7 Manual Technical Description. Safety notes and scope of delivery Technical Description. Safety notes and scope of delivery WARNING! This device is electrically operated. When operating electrical equipment, certain parts of this equipment automatically carry dangerous voltages. Failure to observe these instructions could therefore lead to serious injury or material damage. Only properly trained and qualified personnel are allowed to work on this equipment. This personnel must be fully conservant with all the warnings and commissioning measures as described in this user s guide. The perfect and safe operation of this equipment is conditional upon proper transport, proper storage, installation and assembly as well as on careful operation and commissioning.

8 Technical Description. Range of Application Manual D Subject to change The user s guide has been compiled with great care. However, it may be necessary within the scope of product care to make changes to the product and its operation without prior notice which are not contained in this user s guide. We are not liable for any costs ensuing for this reason.. Range of Application The SIPART DR is a digitally operating device in the top class range. Its program memory contains a large number of prepared function blocks for calculating, controlling, regulating in technical processes which the user can implement without programming knowledge and additional tools. In addition a robust adaptation procedure is available in this device which makes it much easier to commission even critical controlled systems. The controller determines the optimized control parameters independently on request without the user being expected to have any prior knowledge of how the control loop may respond. The applied procedure is suitable for systems with compensation and aperiodic transient behavior; even greater dead times are taken into account. For more complicated applications the fixed connection of the individual functions can be canceled in the input range and replaced by a free structuring. The user can easily add extra analog function blocks and connect them to each other and to the interfaces of the input range with the software. This achieves optimum adaptation even to complex problems. The named programming possibilities guarantee a great flexibility in the use of the controller and allow fast, easy adapting of the device to the problem so that the SIPART DR can be used universally for control jobs in processing engineering, e.g. as fixed setpoint controller for one, two or three-component control, optionally with two setpoints DDC fixed setpoint controller for one-, two- or three-component control follow-up controller (synchronized controller, SPC controller) with internal/external switching fixed or commanded ratio controller with Internal/External switching cascade controller (double controller) ratio-cascade controller (double controller) override controller with Min or Max selection of the manipulated variable (double controller) double controller with two independent control channels The extensive hardware equipment of the instrument by which numerous interfaces are available for connecting the field cables is of advantage for the universal utilization. The instrument can also be connected to master systems via a plug-in serial interface or operated and monitored centrally by a Personal Computer. The SIPART DR can be used alternatively as a continuous controller with a current output signal or as a three-position step controller for controlling electric motor drives without changing the hardware equipment. 8 SIPART DR 6DR C79-G7476-C54-4

9 Manual Technical Description. Design (Hardware). Design (Hardware) The process controller SIPART DR has a modular structure and is therefore maintenance friendly and easy to convert and retrofit. Other signal convertors can be installed in the generously equipped, fully functional standard controller to expand the range of application. These modules are inserted in backplane slots of the enclosed instrument (Fig. -, page ). The standard controller consists of the front module with the control and display elements the main board with CPU and terminal strips the plastic casing with an interface board the power supply unit. The electrical connections between the modules are made by an interface board screwed into the casing. The main board is pushed into rear slot and locked. It holds a -pin and a 4-pin terminal strip to which all inputs and outputs of the standard controller are connected. Five other slots can be equipped with option modules if the number of terminals to the process available in the standard controller are not sufficient for the planned task. The standard controller always has three permanently installed analog inputs (AE) with electronic potential isolation which can be wired alternatively with standardized voltage signals (/. to V or / to V) or current signals (/4 to ma). There are also four digital inputs (BE, /4 V) and eight digital outputs (BA, /4 V, 5 ma) which can be used for different functions depending on the configuration. The SIPART DR also has three analog outputs (AA) which can all supply a current signal from to ma or 4 to ma and be assigned to different variables. A short-circuit-proof Loutput (DC 4 V, ma) is available for supplying transmitters. The power supply unit is located in a fully enclosed metal casing and is screwed tightly to the plastic casing of the controller. This power supply is available in two different versions so that two types of SIPART DR are available: 6DR-4 for power supply connection UC 4 V 6DR-5 for power supply connection AC V, switchable to AC 5 V Many applications can be implemented with the three permanently available analog inputs of the standard controller alone. Two additional input modules can be inserted in slots and for complex jobs or for the connection of other input signals. These input modules are available in addition to for processing normalized current and voltage signals for the direct connection of resistance thermometers Pt and all common thermocouples and resistance sensors or potentiometers. In addition a module with analog inputs (equipment as in the standard controller) can be inserted in slots 5 and 6. This increases the number of inputs to a total of. Slot 4 serves to accommodate an interface module (SES) with V.8-point-pointoutput or SIPART bus interface for serial communication with a master system. A PROFIBUS interface module can be equipped optionally here. SIPART DR 6DR C79-G7476-C54-4 9

12 Technical Description.4 Function principle.4. Standard controller Manual.4 Function principle.4. Standard controller The standard controller consists of three function blocks: Power supply unit Front module Main board Power supply unit Primary clocked power supply plug with high efficiency for AC 5/ V (switchable) or for UC 4 V. It generates the secondary internal supply voltages 4 V and 5 V from the power supply. The metal body is mounted on PE conductors (protection class I). The power supply and internal supply voltages are isolated from each other by safe separation by a protective shield. The internal supply voltages are functional extra-low voltages due to overvoltage cutoff in the event of an error. Since no other voltages are generated in the instrument, these statements apply for all field signal cables (used standards, see chapter.6, page 7). A total of 45 ma are available for the outputs L, AA and BA due to the design for a high power output. Front module The front module contains the control and display elements and the appropriate trigger components for the displays. All display elements are designed in LED technology which provides a longer service life and higher light density as well as a good viewing angle. The control elements are short-stroke switches with a tangible pressure point and high return force. Main board The main board contains the field signal conditioning of the standard controller, the CPU (Central Processing Unit) and the connections (through the interface board) to the module slots. The field signals are fed through protective circuits for external static or dynamic overvoltages and then adapted to the signal levels of the CPU by the appropriate circuits. This adaptation is performed for the analog inputs, the analog outputs and the digital outputs by modern thick-film circuits. The microcontroller used has integrated AD- and DA converters and operates with k batterybacked RAM. The user-specific configuration is stored in an user program memory with a serial 4k EEPROM. When replacing the main board the user memory can be plugged from the old onto the new module. The whole CPU is designed in C-MOS technology. A process image is generated at the start of every routine. The analog and digital inputs and actuation of the front buttons is included and the process variables received from the serial interface are accepted. All calculations are made with these input signals according to the configured functions. Then the data are output to the display elements, the analog outputs and the digital outputs as well as storage of the calculated variables on standby for the serial interface transmitter. The interface traffic runs in interrupt mode. SIPART DR 6DR C79-G7476-C54-4

13 Manual Technical Description.4 Function principle.4. Description of the option modules A large number of prepared functions for controlling processing plants as well as machines and apparatus is stored in the set value memory of the SIPART DR. The user programs the instrument himself by selecting the desired functions by setting structure switches. The total functioning of the instrument is given by the combination of the individual structure switches. Programming knowledge is not necessary for the settings. All settings are made without an additional programming unit exclusively through the front panel of the SIPART DR or through the serial interface. The job-specific program written in this way is saved in the non-volatile user program memory..4. Description of the option modules The following option modules are described in this chapter 6DR8-8A Module with AE, U- or I-input 6DR8-8J I/U module 6DR8-8R R module 6DR8-8V UNI module 6DR85-8A Reference junction terminal 6DR85-8J Measuring range for TC, internal connector 6DR8-8D Module with BA (relays) 6DR8-8E Module with BE and 4 BA 6DR8-8C Module with 5 BE 6DR8-8A Analog output module with y-hold function 6DR8-8B Module with AA and BE 6DR8-8P Serial interface PROFIBUS-DP 6DR8-8C Serial interface RS / RS 485 6DR84-8A Module with 4 BA relays 6DR84-8B Module with BA relays 6DR8-8A Module with AE, U- or I-input D Inputs for current and voltage To expand the analog inputs. For a description of the module and technical data, see chapter.6., page 9 (Inputs standard controller). SIPART DR 6DR C79-G7476-C54-4

14 Technical Description.4 Function principle.4. Description of the option modules Manual 6DR8-8J I/U module D Input variables current /4 to ma or voltage /. to V or / to V The input amplifier of the module is designed as a differentiating amplifier with jumperable gain for to V or to V input signal. For current input signals the 49.9 Ω. % impedance is switched on by plug-in bridges on the module. The start value ma or 4 ma or V or. V ( V) is defined by configuration in the standard controller. The differentiating amplifier is designed for common mode voltages up to V and has a high common mode suppression. As a result it is possible to connect the current inputs in series as for electrical isolation when they have common ground. At voltage inputs this circuit technique makes it possible to suppress the voltage dips on the ground rail by twopole wiring on non floating voltage supplies. We refer to an electronic potential isolation. 6DR8-8R R module D Input for resistance or current potentiometer Potentiometers with rated values of 8 Ω to Ω can be connected as resistance potentiometers. A constant current of Is = 5 ma is fed to the potentiometer wiper. The wiper resistance is therefore not included in the measurement. Resistances are switched parallel to the potentiometer by a slide switch on the module and a rough range selection made. Range start and end are set with the two adjusting pots on the back of the module. This fine adjustment can be made by the displays on the front module (with the appropriate structuring). For adjustment with a remote measuring instrument, the analog output can be assigned to the appropriate input. The external wiring must be changed for resistance potentiometers which cannot withstand the 5 ma wiper current or which have a rated resistance > kω. The constant current is then not fed through the wiper but through the whole resistance network of the potentiometer. A voltage divider measurement is now made through the wiper. Coarse adjustment is made by a remote parallel resistor to the resistance potentiometer. This module can also be used as a current input with adjustable range start and full scale. The load is 49.9 Ω and is referenced to ground. 6DR8-8V UNI module D Direct connection of thermocouple or Pt sensors, resistance of mv transmitters Measured value sensors such as thermocouples (TC), resistance thermometers Pt (RTD), resistance potentiometers (R) or voltage transmitters in the mv range can be connected directly. The measuring variable is selected by configuring the controller in the HdeF level (AE4/AE5); the range and the other parameters are set in the CAE4/CAE5 menu. The sensorspecific characteristics (linearization) for thermocouples and Pt resistance thermometers are stored in the contoller s program memory and are automatically taken into account. No settings need to be made on the module itself. 4 SIPART DR 6DR C79-G7476-C54-4

15 Manual Technical Description.4 Function principle.4. Description of the option modules The signal lines are connected by a plug terminal block with screw terminals. When using thermocouples with internal reference junction terminal, this terminal block must be replaced by the terminal 6DR85-8A. With the measuring for TC, internal connector 6DR85-8J in place of the terminal block, the measuring range of the direct input (/ to mv) can be extended to /uptovor/4uptoma. The UNI module operates with an AD converter with 8 bit resolution. The measuring inputs and ground of the standard controller are electrically isolated with a permissible common mode voltage of 5 V UC. 6DR85-8A reference junction terminal D Terminal with internal reference junction terminal for thermocouples This terminal is used in connection with the UNI module for temperature measuring with thermocouples at an internal reference junction terminal. It consists of a temperature sensor which is preassembled on a terminal block and plated to avoid mechanical damage. 6DR85-8J measuring for TC, internal connector D measuring for TC, internal connector for current /4 to ma or voltage / to V The measuring for TC, internal connector is used in connection with the UNI module to measure current orvoltage. The input variable is reduced to / to mv by a voltage divider or shunt resistors in the measuring for TC, internal connector. Wiper resistors with 5 Ω or 5 Ω are available optionally at different terminals for /4 to ma signals. The electrical isolation of the UNI module is retained even when the measuring for TC, internal connector is used. 6DR8-8D Module with BA relays D Digital output module with relay contacts To convert digital outputs to relay contacts up to 5 V UC. This module is equipped with relays whose switching contacts have potential free outputs. The RC combinations of the spark quenching elements are respectively parallel to the rest and working contacts. In AC consumers with low power the current flowing through the capacitor of the spark quenching element when the contact is open may interfere (e.g. the hold current of some switching elements is not exceeded). In this case the capacitors ( μf) must be removed and replaced with low capacitance capacitors. The 68 V suppressor diodes parallel to the capacitors act additionally to reduce the induced voltage.

16 Technical Description.4 Function principle.4. Description of the option modules Manual WARNING! The relays used on the digital output module are designed for a maximum rating up to UC 5 V. The same applies for the air and creep lines on the circuit board. Higher voltages may therefore only be switched through appropriately approved series connected circuit elements under observance of the technical data and the pertinent safety regulations. 6DR8-8E Module with BE and 4 BA D Digital signal module with digital inputs and 4 digital outputs The module serves to extend the digital inputs and digital outputs already existing in the standard controller. The inputs are designed for the 4 V logic and are non-floating. The functions are assigned to the inputs and outputs by the configuration of the controller. The digital outputs are short-circuit-proof and can drive commercially available relays or the interface relays 6DR848A/8B directly. 6DR8-8C Module with 5 BE D Digital input module with 5 digital inputs The module serves to extend the digital inputs already existing in the standard controller. The inputs are designed for the 4 V logic and are non-floating. The function is assigned to the input by the configuration of the controller. 6DR8-8A Analog output module with y-hold function For auxiliary control device function when servicing and for extending the analog outputs AA to AA existing in the standard controller. Can be inserted in slot 5/6, S/S=4 to be set in the structure mode StrS, Start value of the outputs S7/S49 can be set in StrS. The y hold module contains a microprocessor which maintains serial data communication with the processor on the main board through the Rxd/Txd lines. The processor feeds the U/I converter and the CPU fault message output St through its analog output. The module can be externally supplied through an auxiliary voltage input which is ORlinked with the controller power supply. The analog output of the module is freely available. y hold -function If data communication to the y hold processor is interrupted, the analog output receives its last value. The processor reads the current variable first when data traffic is recovered. The output current is maintained if: 6 SIPART DR 6DR C79-G7476-C54-4

Observe the safety precautions!), if it is powered externally (error message on the front module op. *.6 Err/oP.*.5, see chapter 5, page 7). *.6 Err/oP.*.5, see chapter 5). In this way it is possible to perform all maintenance work right up to replacing the instrument whilst maintaining the controller controlled variable. Handling during module replacement, see chapter 5 Maintenance. St Fault message output This digital output is always high when there is no error and becomes low in the event of an error. It responds when: the self diagnostics of the CPU (see chapter.4., page ) responds. the controller power supply fails, the Y hold module is removed, the main board is removed. 6DR8-8B Module with AA and BE To extend the analog outputs (/4 to ma) and digital inputs can be inserted in slot 5: AA7, AA8, AA9 BE5, BE6, BE7 and in slot 6: AA4, AA5, AA6 BE, BE, BE 6DR8-8P Serial interface PROFIBUS-DP The module 6DR8-8P is a PROFIBUS-DP interface module with RS 485 driver and electrical isolation to the controller. It operates as an intelligent converter module and adapts the private SIPART to the open PROFIBUS-DP protocol. This optional card can be inserted in all SIPART-DR controllers in slot 4. The following settings must be made with the appropriate configurations for the serial interface: Interface on Even parity LRC without Baud rate 96 Parameters/process values writable (as desired) Station number according to selection to 5 Make sure that the station number is not assigned double on the bus. The PROFIBUS module serves to connect the SIPART controllers to a master system for control and monitoring. In addition the parameters and configuring switches of the controller can be read and written. Up to process variables can be selected and read out cyclically by configuration of the PROFIBUS module.

The module can be snapped onto a mounting rail on the back of the controller. The mounting rail is delivered with the interface relay module. One or two relay modules with relays each are installed depending on the version. Every relay has a switching contact with spark quenching in both switching branches. In AC consumers with a very low power, the current flowing (e.g. hold current in contactors) through the spark quenching capacitor (nf) when the contact is open interferes. In this case they should be replaced by capacitors of the same construction type, voltage strength and lower value. The switching contact is fed to the plug terminals with poles so that rest and working circuits can be switched. The relays can be controlled directly from the controller s digital outputs by external wiring. SIPART DR 6DR C79-G7476-C54-4 9

20 Technical Description.4 Function principle.4. CPU self-diagnostics Manual WARNING! The relays used on the interface relay module are designed for a maximum rating of AC 5 V in overvoltage class III and contamination factor according to DIN EN 6 Part. The same applies for the air and creep lines on the circuit board. Resonance increases up to twice the rated operating voltage may occur when phase shift motors are controlled. These voltages are available at the open relay contact. Therefore such motors may only be controlled under observance of the technical data and the pertinent safety conditions via approved switching elements..4. CPU self-diagnostics The CPU runs safety diagnostics routines which either can only after a reset or cyclically. The CPU is familiar with two different types of reset. Power on reset Power-On-Reset always takes place when the 5-V supply drops below 4.45 V, i.e. the power supply is interrupted for longer than specified in the technical data. All parameters and configurations are reloaded from the user program memory into the RAM. At S = the digital x-display flashes as indication after a Power-On-Reset, it is acknowledged by the Shift key (). Flashing is suppressed by S =. Watch dog reset When a watch-dog-reset occurs the parameters and configurations from the user program memory are reloaded into the RAM. The current process variables and the status signals are read out of the RAM for further processing. There are no flashing signals on the front module. CPU-tESt appears in the digital displays dd and dd for a maximum 5 s after every reset. Every error detected by the self-diagnostics leads to a flashing error message on the digital displays dd and dd with defined states of the analog and digital outputs. The fault message output St of the y hold module becomes low. The reactions listed in the table are only possible of course (since this is a self-test) if the errors occur in such a way that the appropriate outputs or the front module can still be controlled properly or the outputs themselves are still functioning. There are other error messages for the input range which indicate defective structurings within this range (see chapter.5.6 Error messages, page 99). In addition error messages are output in the adaptation (see chapter.. Parameterization mode AdAP, page 7). The digital displays flash in the case of error messages. SIPART DR 6DR C79-G7476-C54-4

22 Technical Description.5 Functional description of the structure switches.5. Analog input signal processing permanently connected Manual.5 Functional description of the structure switches (S to S7, S to S68) In the factory setting (setting when the device is delivered) most of the structure switches are set to. This corresponds to the most usual setting of the individual functions so that only few structure switches need to be set selectively during commissioning. However, it is recommendable to compare the individual structure switch settings with the task. With structure switch S the user program can be identified by a number from to 54 in the structuring mode Strs. The setting corresponds to the factory setting and is regenerated automatically in the APSt function (All Preset). All changes in parameters or structures in relation to the factory setting automatically set S from to. The structure switches S and S are fundamentally significant. With S the controller type is set and thus the processing of command variable, main controlled variable and auxiliary controlled variables up to control difference generation determined. With S the controller output structure is set and thus the processing of the automatic-, manual-, safety- and followup variables as well as the manipulated variable output determined as a K- or S-output..5. Analog input signal processing permanently connected (S to S, S to 5) In the structure switch setting S4= the analog input range is permanently connected (see figure -5, page 4). With S4= the permanent connection is canceled and converted into a freely connectable input range (see chapter.5., page 5). Every one of the maximum analog inputs is fed through an AD converter which performs the 5 or 6 Hz interference suppression by averaging over or 6 / ms. After this the signal range to ma or 4 to ma is normalized to to % calculated value per channel with S5 to S9 or S to S5. At the same time it is decided with S5 to S9 or S to S5 whether operation is to take place with or without range monitoring (transmitter fault). The monitor signals per channel on dropping below.5 % or exceeding 6.5 % with a hysteresis of.5 % to the digital x and w display. By an OR link of all single messages the group transmitter fault MUF is formed which can be assigned to the digital outputs and negated optionally (see chapter.5.8, page ). Only the analog inputs selected with the transmitter fault monitor are monitored, displayed on the front panel (the appropriate position stays dark in the case of analog inputs not selected with transmitter fault) and signaled with the OR link. The error message is acknowledged with the Shift key (). The fault message signal via the OR link is available until the appropriate analog inputs are back in the working range. After the range monitoring the analog inputs are fed through a st order filter which can be set by the parameters tf to tfb in the range of off,. to s in the parameterization mode onpa. The factory setting is s. With S to S4 or S6 to S every channel can now be root extracted optionally. After root extraction, the analog inputs are available for further processing as AEA to AEbA.

The outputs of the analog inputs AEA to AEbA are now assigned to the function inputs FE to FE by the structure switches S5 to S9 or S to S7. The outputs AEA to AEbA and the function inputs FE to FE are available for the assignment to analog outputs, the limit value alarm and the parameter control and can be read through the SES. With this input structure most control tasks can be solved in connection with the different controller types and controller output structures. SIPART DR 6DR C79-G7476-C54-4

25 Manual Technical Description.5 Functional description of the structure switches.5. Analog input signal processing freely connected (S4 = ).5. Analog input signal processing freely connected (S4 = ) The structure switch setting S4= cancels the permanent connection at S4= in the analog input range and replaces it with a freely connectable input range. The freely connectable input range basically represents a multifunctional unit, configuring takes place according to the same rules. Up to the outputs AEA to AEbA (AEA), the signal processing is identical to that described in chapter.5., page. The function inputs FE to FE also operate in the same way with the difference that FE5 (follow-up input) and FE6 (position feedback input) can be used in parallel and with the difference that FE5 (followup input) and FE6 (position feedback input) can be used in parallel and connected with different signals. Nine different function blocks which occur with different frequency can now be connected absolutely freely between the outputs AEA to AEbA and the function inputs FE to FE. The outputs AEA to AEbA represent data sources whilst the function inputs FE to FE are data sources. Parallel to the outputs, 5 connectable linear parameters are arranged with a setting range of to (corresponding to % to %), a number of normal constants as well as other variables gained from the controller as data source. The function blocks have a different number of inputs (data sinks) and output each (data source) depending on the function depth. The function blocks function transmitter and correction computer have assigned parameters which can be set in the structuring mode ofpa. The connectable parameters P to P5 are set in the parameterization mode onpa. By structuring on the front module the necessary functions are selected or defined (structuring mode FdEF), connected (structuring mode FCon) and correctly positioned in time in the cycle (structuring mode FPoS), see chapter..7, page to..9, page 5. Connection is absolutely free, i.e. any data source can be connected with any data sink. The operating effort is minimized by fading the data sources and sinks from undefined function blocks. In addition the data sinks which are not obliagatory for a function are preoccupied by constants which can be overwritten. The inputs preoccupied with ncon (not connected) are absolutely essential for the function and must be connected. This very variable connection facility in the analog input range also enables complex control tasks to be solved. No distinction is made between analog and digital signals. Digital inputs have a threshold value of.5. Digital outputs supply a value of % () or % (). SIPART DR 6DR C79-G7476-C54-4 5

Parabolae are set by the computing program between these vertex values which interlink tangentially the vertex values so that a constant function is produced.

When used as a linearizer for the displays, the linearization function is entered by the vertex values so that the series circuiting of the sensor function gives a linear equation with the linearization function (see chapter.5.4, figure - to figure -, page 46)..5..

According to the law of continuity the flow of a flowing liquid in a pipe is the same at all places. If the cross-section is reduced at one point, the flow speed at this point should increase. According to Bernoulli s energy equation the energy content of a flowing material is made up of the sum of the kinetic energy (due to the speed) and the potential energy (of the pressure). An increase in speed therefore causes a reduction in pressure. This drop in pressure, the so-called active pressure Δp is a measure of the flow q. The following applies: q = c Δp with c as a factor which depends on the dimensions of the pipe, the shape of the constriction, the density of the flowing medium and some other influences. The equation states that the active pressure generated by the constriction is in the same ratio as the square of the flow. SIPART DR 6DR C79-G7476-C54-4 9

Analog input signal processing freely connected (S4 = ) Manual Δp q Figure - Relationship between flow q and active pressure Δp To measure the flow, a choke is installed at the measuring point which constricts the pipe and has two connections for tapping the active pressure. If the properties of the choke and the measuring material are known to the extent that the equation specified above can be calculated, the active pressure is a measure of the flow. If you have chosen a certain choke, the flow can be described in the calculation state or operation state. q B = K ρ B Δp or q = K ρ Δp Since the density is included in the measuring result according to the above equation, measuring errors occur when the density in the operating state differs from the value based on the calculation of the choke. Therefore a correction factor F is introduced for the density in operating condition. F= B V B V = with V= as specific volume. as specific volume. In order to be able to perform the correction with the factor F, the current specific volume must be determined first. For the dry gases the densities change according to the laws for ideal gases: V = R T p = ρ The correction factor is then given as: F = T B p T with p as absolute pressure and T as absolute temperature. pb SIPART DR 6DR C79-G7476-C54-4

Assignment and direction of effect of the digital inputs see fig. -6, page 7 The control signals CB, He...yBLII, -yblii are assigned by the structure switches S4 to S8 and S9 to S8 to the digital inputs BE to BE4 or the status Lo. In the assignment of CB (S4), CBII (S9), PI (S), PII (S), wsli (S5) and wslii (S6) the High status (S** = ) is also possible. The control signals can be negated optionally by the structure switches S9 to S46 and S9 to S. The digital inputs BE to BE4 of the standard controller can be extended with the option modules 6DR8-8C, 6DR8-8E, 6DR8-8B in slot 5 and in slot 6. When using option modules in slots 5 and 6 the structure switches S and S must be set according to the assembly, otherwise it will lead to error messages (see chapter.4., page ). All digital inputs can be read by the SES..5.. Linking the digital inputs BE bis BE4 to the control signals via the SES (S47 to S49, S) see fig. -7, page 8 The control signals CB and N may be available optionally as static signals or as a pulse (key operation on consoles) at the digital inputs. The setting is made by S47 for CB and S48 for N. On selecting the pulse input, every positive edge flips the flip-flop. In the following descriptions the output status of the flipflop is assumed as CB or N. All control signals except Δw and Δy can also be preset by the SES at S =,, 4, 5 and OR linked with the appropriate control signals through the digital inputs. The incremental adjustment of w or y by the SES is not advisable on account of the bus run times. Since the top operation hierarchy in a computer link should be with the autarcic single controller, the control signals can be switched off by the SES by rounding with RC = Int CB via the Internal/External key () of the controller or via CB ES (optionally time-monitored) or via CB BE (central Computer Fail line). In addition the internal flip-flop can be activated at S = to 5 parallel to pressing the keys via IntES. The CB signal is formed at S =, 4 as an OR function of CB ES via the serial interface and CB BE via a digital input so that operation can take place optionally with one signal. At S =, 5 the OR function is replaced by an AND function so that the CB set by the SES can be reset via a central Computer Fail line. The function RC = Int CB (computer operation) also controls the command variable switching in all controller types, i.e. also in SPC-mode or manipulated variable switching in DDC mode (see chapter.5.4, page 4). The two controller types S = / operate without command variable switching. The Internal key and the control signal CB are available with the link RC = Int CB for locking operation through the serial interface (e. g. when coupling to control systems).

36 Technical Description.5 Functional description of the structure switches.5. Digital input signal processing Manual At S47 = static switching takes place due to the logic function RC = Int CB. In the case of the preset to Int(Internal LED () off) you can switch statically with CB between controller values and computer values (command and manipulated variables). The computer standby CB is displayed negated by the C-LED () (C = CB, CB = = C LED off). The computer standby of the controller is signaled negated as a message signal RB = Int. The computer mode is also signaled negated as a message signal RC = Int CB. At S47 = static switching with acknowledgement takes place. Every time the computer is recovered (CB from! ) the internal flipflop is set to (Internal LED on, C LED off) so that the computer mode RC = Int CB only becomes active after pressing the Internal key (Int=). With S49 the Internal/External key can be switched out of function and only internal or external operation preselected. The control signal H is generated as an OR-function by the Manual-/Automatic key (9) with subsequent flip-flop (Hi) and the control signal He whereby He can be preset by the SES or the digital inputs in the way described above. With the structure switch S64 Automatic-/Manual switching can be blocked in the positions only Automatic (H = ) or only Manual (H = ). The Manual LED (8) always indicates the active status (see also chapter.5.6, page 99). At S64 = to, He is connected statically by both the SES and the digital inputs. At S64 = /4 the connection is made dynamically, i.e. every positive edge causes manual-automatic-manual opeeration switching. Additionally interlocking of He ES with RC =Int CB is canceled at structure switch S64 = 4. 6 SIPART DR 6DR C79-G7476-C54-4

Blocking parameterization and structuring The entire configuring of the device is blocked, this means the parameterization as well.

General, recurrent functions Manual setpoint preset wi or nominal ratio preset wvi on the control front panel. The internal setpoint can always be adjusted with the Δw-keys (6 Fig. -) when the green internal LED () lights up. The adjusting facility is marked by in the tables. Exceptions to this rule are expressly mentioned in the individual controller types. The adjustment operates incrementally, in the first step with a resolution of digit and then an adjustment progression so that major changes can also be performed fast enough. After every interruption in the adjustment by releasing the keys, the progression starts again with the smallest adjustment step. Setpoint preset wi or nominal ratio preset wvi by the SES Every time the internal setpoint can be adjusted by the keys (6) on the control front panel, it is also possible to make a preset with the SES. Since only absolute and not incremental adjustment is possible with the SES, it is advisable to use the setpoint ramp ts to avoid steps. In addition the control signal Int and the automatic/manual switching can be preset with the manual manipulated variable adjustment with the SES so that a complete parallel process operation is possible with the SES (see also chapter.5.6 Controller output structure, section Control system coupling via the serial interface on page ). Source for the external setpoint S5 and S The external setpoint we can come from a maximum of three different sources in the different controller types: external setpoint as an absolute value via the analog inputs (w EA ) Selection with S5 external setpoint incremental via the control signals Δw (w EΔ ) external setpoint as an absolute value via the SES (wes) SES (w ES )selection with S In double controllers (S = ) you can switch between w ES and w EA respectively with control signal w SLI or w SLII.

Setpoint limits SA, SE (accordingly SAII, SEII at S = ) With the parameters SA and SE (ofpa) the effective setpoint w can be limited to minimum value (SA) and maximum value (SE) in the range from - to %. Exception: Ratio controller (S = 4) and ratio cascade, commanded ratio controller (S = 6) Follow-up of the ineffective setpoint to the active setpoint (S5) (accordingly S5 at S = ) Normally the ineffective setpoint is followed up to the effective setpoint so that the setpoint switching is bumpless. The internal setpoint (wi), the external setpoint incrementally adjustable via Δw (w EΔ ) and the external setpoint via the SES (w ES ) can be followed up. The safety setpoint SH cannot be followed up. The external setpoint w EA via the analog inputs can only be followed up indirectly by following up the supplying device on the output side. To do this the effective w is used as a follow-up variable, assigned to an analog output and as a followup control signal the OR-operation H N Si, assigned to a digital output. At S5 = the follow-up is suppressed. This switch setting is always required especially in follow-up controllers if the internal setpoint represents a kind of safety function or if multiple setpoint operation is to be run in follow-up controller (S = ). x-tracking (S5) (accordingly S at S = ) With the structure switch S5 =, x-tracking (ratio controller xv-tracking) can be switched on. This means that the setpoint is followed up to the actual value or the nominal ratio is followed up to the actual ratio and therefore a control difference xd is reset to. The follow up always takes place when there is no automatic operation (A). This is the case in manual mode (H), follow-up mode (N), DDC mode and in operation with safety manipulated variable (Si): A =H N Si SIPART DR 6DR C79-G7476-C54-4 4

42 Technical Description.5 Functional description of the structure switches.5.4 Controller types (S, S49 to S5) Manual x-tracking in direction-dependent blocking operation is not possible because the P-step produced by resetting the driving control error to blocking direction would immediately cancel the blocking. x-tracking takes place without the set setpoint ramp ts. By following up the setpoint to the actual value (nominal ratio to actual ratio), the control difference xd = and automatic operation starts absolutely bumplessly. Since one can usually assume in manual mode and DDC mode that the actual value has been driven to the desired value, the followed up setpoint corresponds to the rated value. x-tracking only takes full effect if the follow-up of the inactive setpoint is locked onto the active setpoint (S5 = ) so that not only the active setpoint w but also the setpoint source which is supplying after switching to automatic operation is followed up. At S5 = (without follow-up) the control difference is during the A-operation but after switching to the automatic mode the old non-followed up setpoint is immediately active again. With the setpoint ramp ts this step-shaped setpoint change takes place via a time ramp. This combination is always useful when it is not guaranteed during A-operation (especially in safety mode) that the actual value will be driven to the desired rated value by the actuating manipulation and the follow-up variable would not be correct in full x-tracking. Constants c to c7 In the individual controller types the process variables are partially linked with each other whereby the constants c to c are used for the controlled variable links and constants c4 and c5 for the command variable links. The constants are set in the parameterization mode onpa in the range from to The constants c6, c7 serve to dose the disturbance variable connection to the controller output yi or yii (see chapter.5.5., figure -5, page 9 and figure -5, page 9). They can be set in the parameterization mode onpa in the range from to Control signals for the setpoint switching If available in the single controller types, the setpoint switching takes place depending on the control signals Int (Internal/External key) and CB (Computer standby) as an AND function RC = Int CB and its negation. The status of the control signal CB and the Internal key () is indicated by the C LED () and the Internal LED (). With S49 the Internal/External key () can be set out of function and can block in the positions Internal or External (see chapter.5., figure -7, page 8). The factory setting is S49 = only Internal. With S4 the CB signal can be set to Lo or Hi or a digital input assigned, (see chapter.5., figure -6, page 7). The factory setting is S4 = -, CB =. 4 SIPART DR 6DR C79-G7476-C54-4

The corresponding adjustment keys and status-led s are assigned in color and position to the displays. The two analog displays always indicate the active actual value. The difference between the two displays is the control difference xd or the control error xw = xd. The digital actual value display also indicates the current actual value except in the ratio controllers (ratio controller: actual ratio). The digital setpoint display indicates the setpoint before the setpoint ramp except in ratio controllers (ratio controller: nominal ratio before the setpoint ramp).

In K-controller circuits, the actuating current can be output parallel by the computer periphery to achieve full redundancy. In this case the actuating current of the K-controller is switched off during computer operation (S66 = ). If the actuating current of the computer is also to be switched off during controller operation, the two currents simply need to be added by OR diodes. This OR diode is integrated in the current outputs of the SIPART controllers. If the UI-converter of the K-controller is to be used during computer operation to feed the final control element, the actuating current cutoff must be canceled (S66 = ).

With S6 the priority between DDC-mode and manual mode is determined. If DDC-mode has priority over manual mode, you can select with the manual-automatic switching whether operation is to continue after a computer failure in automatic or manual mode.

The external setpoint can be preset via the analog output FE (w EA ) or via the digital signals Δw as an incremental setpoint (w EΔ ) (selection via S5) or via the SES (w ES ) (selection by S). The active setpoint w can be fed back by an appropriately assigned analog output to the feeding controller for follow up when using wea or for displaying when using weδ. This controller type is used for cascade controls with separate controllers (master and follow-up controllers), for synchronized controls, fixed setpoint controls with external setpoint preset (e.g. under console conditions via the incremental Δw-inputs) and SPC-controls (setpoint control). This controller type attains special importance when coupled with the SIPART software for operation and monitoring. Here this controller type is used for fixed setpoint control with external setpoint preset (w ES ) and Automatic/Manual switching via the follow-up signal N ES and the input y ES (see chapter.5.6, page 99). SPC controls Here a process computer takes over the setpoint command during computer operation RC = Int CB =, in the event of a computer failure (CB from! ) the controller takes over either the last computer setpoint (followed up wi) or the safety setpoint SH (selection via S5). 58 SIPART DR 6DR C79-G7476-C54-4

59 Manual Technical Description.5 Functional description of the structure switches.5.4 Controller types (S, S49 to S5) Cascade control A command controller, e.g. a fixed setpoint controller (with the main controlled variable) feeds the external setpoint of a slave controller with its manipulated variable (with the auxiliary controlled variable, disturbance variable) and this the actuator. This gives faster control of the main controlled variable in the event of changes in the auxiliary controlled variable, e.g. furnace temperature control (furnace temperature, main controlled variable) with different flow of the medium to be heated (auxiliary controlled variable). Synchronized controls A master controller feeds several synchronized controllers simultaneously whose individual setpoints can be set in a ratio to each other by the constants c4 and c5 and then drag the controlled variables accordingly (controlled variable synchronization). Internal/External switching The setpoint switching takes place via a logic link RC = Int CB and its negation (see table, page 6 and table, page 6). Both control signals can be set statically to or (int via S49, CB via S4) in addition to their normal functions as Shift key or control signal with the states and, see chapter.5. fig. -6, page 7 and fig. -7, page 8. The factory setting is Int = (S49 = ) and CB= (S4 = -), so that in the factory setting the internal setpoint wi is always active and cannot be switched! With this setting facility it is possible to perform the switching only dependent on Int (S49=, S4= -) or only dependent on CB (S49=, S4= to 4) as a slave controller with Internal/ External-switching. If the switching facility is blocked in External position (S49=, S4=-), the controller operates as a follow-up controller without Internal/External-switching (see table -, page 4). Display of the external setpoint w E With the Shift key () the digital w-display can be switched to the external setpoint we and the digital x-display to the main controlled variable x in the display level II (display range I must be set, display range II is automatically set the same). The active setpoint and the active actual value are still indicated on the analog displays. The LEDs Controller I/Controller II signal the display level. Flashing signals that the displayed external setpoint is not identical with the active setpoint. Steady light signals that the displayed and active setpoints are identical. SIPART DR 6DR C79-G7476-C

The ratio factor range v = va to ve is determined with the parameters va and ve in the structuring mode ofpa in the range from. to (factory setting va =, ve = ). In addition a basic value c5 (parameterization mode onpa) can be connected in the range from to (factory setting =.). The standardized nominal ratio wv (wvi or wv E ) in the range from to is converted to the ratio factor range. v=wv(veva)va With w=v x c5, w = wv [(ve va) va] x c5 is given. 64 SIPART DR 6DR C79-G7476-C54-4

65 Manual Technical Description.5 Functional description of the structure switches.5.4 Controller types (S, S49 to S5) In the ratio controller the standardized nominal ratio wv and the standardized actual ratio xv are displayed on the digital w and x displays respectively. Via d*i a physical display is possible. The controlled variable x and the evaluated commanding procesan be switched to the external nominal ratio (display level II) (display level I must be set, display level II is automatically set the same). Signaling of the display levels, see S =, fos variable w are displayed on the analog x and w displays respectively so that a direct control difference monitoring is possible at all times. With the Shift key () the digital w-display cllow-up controller. The digital x-display shows the actual ratio xv in both display levels. The actual ratio is gained by back calculating the ratio formula with the current process variables x, x: v is = xc5 x v ist = xv (ve va) va gives for xv = v isva veva or xv = xc5 -va x veva xv is displayed and is required for x-tracking mode. For the xv-display, x and x are limited to,5 % so that the display does not become too restless for small x and x or flip from positive to negative in the case of negative x. The linearizers can be used for linearization of the commanding process variable x (via FE in the freely connectable input range) and the following process variable x (via FE also in permanently connected input range). The linearization then acts on the analog displays and the ratio formation and therefore indirectly on the digital displays for nominal and actual ratio. The ratio controller has no nominal ratio limiting because the ratio factor range already marks the limit. The commanding process variable x can be limited by the freely connectable range (S4 = ) if necessary. The ratio controller behaves like slave controller S = in switching of the setpoint ratio wv so that the information and tables there apply accordingly. The variables wi and w E must be replaced by wvi and wv E. This controller type can also be used as a ratio controller with fixed ratio (manually adjustable) or with commanded ratio factor. A fixed ratio factor is used for example in simple combustion rules, (see example in figure -) where the ratio factor is reset manually if necessary for varying fuels. If it is possible to measure the effects of the ratio factor (combustion quality, pollutants in the flue gas) a commanded ratio controller is used. Here a master controller adjusts the ratio factor (ratio cascade) with the combustion quality as a control variable. Another application for ratio cascades are concentration controls, e.g. ph-value controls. The ph-value is the controlled variable of the master controller, the flow of alkali and acid the commanded process variable and the following (controlled) process variable of the ratio controller.

Selection is made with w SL II and S. In computer coupling it is also possible here, in the case of a computer failure (CB from! ) to continue working with the last computer setpoint (followed-up wi) or with the safety setpoint SH (selection by S5). The master controller cannot be switched to manual operation but the slave controller can be switched to the internal setpoint. Follow-up of the inactive setpoint to the active setpoint can be switched off with S5 =. Follow-up controller (controller I) The follow-up controller can be switched for disconnecting the cascade for startup procedures via the Internal/External key () (Int I) between the internal setpoint wii and the external setpoint wei which is equal to the manipulated variable of the master controller (yaii). The internal operation of the follow-up controller corresponds to manual operation of the master controller. Setpoint limiting of the follow-up controller can be implemented by the y-limiting of the master controller. The follow-up of the master controller in internal operation of the follow-up controller and x-tracking (A) and the follow-up of the internal setpoint of the follow-up controller in external operation and x-tracking (A) always takes place so that the switching Internal/External is bumpless.

(Applications see S = 4) Master controller The master controller has the same structure with respect to the setpoint switching as the follow-up controller S =. It is therefore a fixed setpoint controller with the possibility of external setpoint preset via the analog signal, the serial interface or as an incremental setpoint via the control signals Δw. Selection is made with w SL II and S. In computer coupling it is also possible here, in the case of a computer failure (CB from! ) to continue working with the last computer setpoint (followed-up wi) or with the safety setpoint SH (selection by S5). The master controller cannot be switched to manual operation but the follow-up controller can be switched to the internal setpoint. x-tracking in A-operation is possible by selection with S5 =. The follow-up of the inactive setpoint to the active setpoint can be switched off by S5 =. Follow-up controller The follow-up controller is a ratio controller as described under S = 4. To disconnect the cascade the Internal/External key () (Int I) can be used to switch between the internal ratio factor wvi and the external ratio factor wv E, which is equal to the manipulated variable of the master controller (yaii). The internal operation of the follow-up controller corresponds to manual operation of the master controller. xv-tracking is possible in A-operation by selection with S5 =. Setpoint limitings can be performed via limiting of the manipulated variable of the master controller and possibly by limiting the commanding process variable x I in the freely connectable input range (S4 = ). The follow-up of the master controller and xv-tracking in A-operation and the follow-up of the internal ratio factor wvi in external operation and in x-tracking (A) always takes place so that switching is bumpless.

The non-intervening controller then has a control difference which controls it to the limited manipulated variable. In this case all further integration is prevented so that no integral saturation takes place. Disconnection always takes place at the latest when the control diffrence in the non-intervening controller reverses. Changes in the controlled variable in the direction of the control difference reversal also lead to disconnection via the P-part (possibly also D-part). This gives a particularly good dynamic behavior. By the arrangement of two controllers, better adaptation to the different time behaviors of the two controlled systems is achieved than with a Minimum- or Maximum selection of the control differences. The possible implementation by Minimum or Maximum selection of the manipulated variables can lead to dynamic problems due to integral saturation of the non-intervening controller.

78 Technical Description.5 Functional description of the structure switches.5.4 Controller types (S, S49 to S5) Manual - Example: Core temperature control with maximum casing temperature limiting The core temperature of a reactor is to be controlled without the cooled casing of the reactor exceeding a specific temperature (limiting setpoint Sb). In error-free operation the main controller (Controller I) controls the core temperature to the set setpoint w core. Since the casing temperature is below the critical limiting setpoint Sb, the limiting controller (Controller II) has a positive control difference. The manipulated variable of the main controller is fed increased by % to the limiting controller as a maximum limiting variable and forms its maximum manipulated variable. The limiting controller is driven to this limit by the positive control difference. Its manipulated variable is also fed to the main controller as a maximum manipulated variable limit but remains ineffective because it is an increase of % above the manipulated variable of the main controller. In this situation the main controller can set its manipulated variable totally independently of the limiting controller and control the core temperature of the reactor. Sb=w case x case YE Controller II Casing temperature controller (Limiting controller) w core x core Controller I YE y S=8 Core temperature controller (Main controller) Figure -4 Core temperature control with max. casing temperature limiting If the casing temperature rises above the set limiting value Sb, e.g. due to failure of the cooling water, the limiting controller gets a negative control difference. As a result its manipulated variable is released from the forced limit and the heating performance is reduced. The limiting controller then forces the reduced manipulated variable on the main controller as a maximum manipulated variable limit. Due to the reduced heating performance the main controller receives a positive control difference which drives it to the manipulated variable limit. Now the limiting controller controls the process to constant casing temperature. When the cooling is reinstated, the casing temperature drops. The limiting controller will now increase the heating performance and maintain the casing temperature. With increasing heating performance the core temperature also increases and the control difference of the main controller becomes negative. 78 SIPART DR 6DR C79-G7476-C54-4

79 Manual Technical Description.5 Functional description of the structure switches.5.4 Controller types (S, S49 to S5) As a result the main controller controls down its manipulated variable and with it the heating performance and imposes the manipulated variable limit on the main controller. The case temperature drops below the limiting setpoint and the limiting controller drives to the manipulated variable limit via the now positive control difference. It is controlled to a constant core temperature. The disconnection therefore always takes place when the controlled variable of the non-intervening controller becomes more positive than the set setpoint (xd negative), then the manipulated variable limited to maximum is dropped below, i.e. a maximum value limiting of the controlled variables takes place. The manipulated variable maximum value limiting corresponds in this example to a minimum value selection of the manipulated variables. Depending on the structure switch position (S = 7 or 8) and the set controller direction of effect (normal: Kp or reversed: -Kp) the limiting direction of the controlled variables is reversed (Minimum- or Maximum value limits): S Manipulated variable limiting direction corresponds to y- selection Controller direction of effect Main controller I Limit ing controller II Main controller I Disconnection at Limiting controller II Limiting of the controlled variables to 7 ya Max norm Kp norm Kp xdi >, xi< wi xdii >, xii <Sb Min Min 7 ya Max rev -Kp rev -Kp xdi <, xi >wi xdii <, xii >Sb Max Max 8 ye Min norm Kp norm Kp xdi <, xi >wi xdii <, xii >Sb Max Max 8 ye Min rev -Kp rev -Kp xdi >, xi <wi xdii >, xii <Sb Min Min 7 ya Max norm Kp rev -Kp xdi >, xi <wi xdii <, xii >Sb Min Max 7 ya Max rev -Kp norm Kp xdi <, xi >wi xdii >, xii <Sb Max Min 8 ye Min norm Kp rev -Kp xdi <, xi >wi xdii >, xii <Sb Max Min 8 ye Min rev -Kp norm Kp xdi >, xi <wi xdii >, xii >Sb Min Max xi xii Table -5 Limiting direction of the controlled variables depending on S = 7/8 and controller direction of effect The direction of effect of the transmitter, actuator and controlled system are included in the determining of the controller direction of effect (see chapter 4., page 5).

80 Technical Description.5 Functional description of the structure switches.5.4 Controller types (S, S49 to S5) Manual Main controller I The main controller has the same structure with respect to the setpoint switching as the follow-up controller (S = ) with the difference that the external setpoint we cannot be preset via the analog inputs as an absolute value. It is therefore a fixed setpoint controller with the possibility of external sepoint preset via the SES or as an incremental setpoint via the control signals Δw. Selection is made by S. In computer coupling it is also possible here, in the case of a computer failure (CB from! ) to continue working with the last computer setpoint (followedup wi) or with the safety setpoint SH (selection by S5). x-tracking in A-operation is posssible by selection with S5 =. The follow-up of the inactive setpoint to the active setpoint can be switched off by S5 =. Limiting controller II The limiting controller has a normal fixed setpoint structure without x-tracking and setpoint switching possibilities. The limiting setpoint Sb is set physically in the structuring mode ofpa in the range from - to % related to the display range deii -daii = %. Display and operating level switching The display and operating level switching Controller I or Controller II takes place in all operating modes with the Shift key ().

As a rule the display level switch is in position I (main controller) so that the main controller variable xi canbemonitored. Flashing of the Controller LED I signals that the limiting setpoint has been reached and requests switching to the display level II (limiting controller) with the controlled variable of the limiting controller. The display range must be set separately for the digital x and w display for both controllers with the parameters d*i and d*ii if necessary in connection with the linearizers so that both controllers can be displayed correctly. Automatic/Manual switching Since both controllers only generate one common automatic manipulated variable y a,the Automatic/Manual switching of both controllers is also common. In manual-, follow-up-, safety- or blocking operation, both controllers are followed up to the active y. The manipulated variable limit which is only active in automatic operation via the parameters YAI and YEI represents an absolute manipulated variable limit in automatic operation. The mutual follow-up of YA or YE can only take place up to the set limits. By setting YAI and YEI, YAII and YEII are set to the same value automatically on leaving the parameterization mode onpa.

92 Technical Description.5 Functional description of the structure switches.5.5 Control algorithm, parameter control, adaptation Manual Controller direction of effect The controller direction of effect is set with S54 (controller I) or S56 (controller II), it must always have an opposite behavior (reverse coupling) to the controlled system (including actuator and transmitter) S54/56=, normally acting controller (Kp, rising x causes falling y) for normally acting systems (rising y causes rising x) S54/56=, reversing controller (Kp, rising x causes rising y) for reversing systems (rising y causes falling x). Operating point yo for P-controller The operating point yo of the P-controller can be set either automatically or as a parameter (onpa). Automatic operating point (Yo = Auto) Whenever there is no automatic operation (manual, follow-up, safety or blocking operation) the operating point yo is followed up so that switching to automatic operation is bumpless. This gives an automatic setting of the operating point yo in manual mode: yo = y H K p (wx H ) c6 z y II in controller II or yo = y H K p (wx H ) c6 z y in controller I If the actual value in manual mode (x H ) is driven to the desired setpoint (w) by the appropriate manual manipulated variable (y H ), the operating point (yo) is identical to the manual manipulated variable (y H ). yo = y H or yo = y H c6 z y. Set operating point (Yo = to %) The controller operates in all operating modes with the operating point set as a permanent parameter. Bumpless switching to automatic mode If there is no automatic operation (manual, follow-up, safety or active blocking operation) the I-part or the operating point yo (only at Yo = Auto) is followed up so that the switching to automatic operation is bumpless. Any still active D part is set to zero. P-PI switching With the control signal P*= the controller is switched from Pi to P-behavior, at Yo=Auto the switching is bumpless. 9 SIPART DR 6DR C79-G7476-C54-4

93 Manual Technical Description.5 Functional description of the structure switches.5.5 Control algorithm, parameter control, adaptation Manipulated variable limiting ya, ye (yaii, yeii at S=) The manipulated variable limiting with the parameters YA and YE is active in automatic operation in any case. The limits of these parameters are at and %. However, it should be taken into account that the controllers neither output negative actuating currents nor detect any negative position feedback signals. If the manipulated variable y a reaches one of the limits YA or YE in automatic mode, further integration is aborted to avoid integral saturation. This ensures that the manipulated variable can be changed immediately after reversing the polarity. In manual-, follow-up- (DDC) or safety operation the manipulated variable y can be driven out of the limiting range (only at S45= or S46=). When switching to automatic mode the last manipulated variable is transfered bumplessly, then only changes in the manipulated variable in direction of the range YA to YE are executed. In controller I the manipulated variable limiting is only possible in K-controllers and three-position step controllers with external position feedback (S= and S=). Adaptive filter The control difference xd is fed through an adaptive filter. By adjusting tfi or tfii (onpa) from off to s the filter is switched on. By further increases to tf* the filter can be adapted to a lowfrequency disturbance frequency (seconds to hours time constant). Within a band in which changes repeatedly take place, changes are seen as disturbances by the filter and are filtered with the preset time constant tf*; Changes in a direction leading out of the band are passed unfiltered to the Pi(D) algorithm to enable fast control. If the disturbance level changes in time, the filter is automatically adapted to the new level. E t A t Figure -5 Effect of the adaptive non-linear filter The factory setting of tfi and tfii is s. In controllers with D-part it should be set as great as possible because of the input noise amplified by vv Kp and in the adaptation (see chapter 4.4, page 9). SIPART DR 6DR C79-G7476-C54-4 9

It should be taken into account that the remaining control difference can adopt the value of the set response threshold AH. The factory setting of AH is % and can be set up to % in the parameterization mode onpa. In S-controllers the minimum necessary setting of AH is given by the minimum Δx=ks Δy (see chapter 4., page 8) and can be increased for further calming of the controlled system. In K-controllers a small threshold value is advisable for calming the control circuit and reducing wear. Parameter switching The single controllers, i.e. fixed setpoint controllers with two independent setpoints, fixed set-point controllers with two dependent setpoints, DDC-fixed setpoint controllers, follow-up controllers (synchronized controllers, SPC-controllers) and ratio controllers operate with the parameter set I and can be switched via the control signal PAU = to the parameter set II. Both parameter sets are separately adjustable in the parameter mode onpa. Every parameter set contains the parameters vv, cp, tn tv, AH, Yo, YA and YE with the ID I or II. The switching facility is conceived for -batch mode and should be performed manually since it cannot be bumpless in automatic operation. Double controllers (cascade control, ratio cascade control and override control) operate with the separately adjustable parameter sets I and II for the controllers I and II. There is no longer a possibility of parameter switching by the control signal PAU. Parameter control With the structure switch S59 the parameter sets I or II can be replaced by a controlled parameter set except for YA and YE. In double controllers one of the two controllers can operate with controlled parameters. In single controllers the controlled parameter set can be used for operation and additionally it can be switched to a fixed parameter set by the control signal PAU.

Beyond the marginal vertex points and 9 % the set values remain constant. (Exception: Yo can be controlled over the whole range to %.) For parameters which do not need to be controlled, same values are set for all vertex points. The derivative action gain vvc is not controllable but can be set in the range from. to. When controlling tv a supplementary condition must be satisfied: tv. to tv.9 must either be all = off (Pi or P controller) or all off (PID or PD controller). Otherwise the error message tv/err appears when jumping out of the structuring mode PAST with the Exit key (see chapter.., page 75). Yo is controllable in the range from to % and then acts like a fixed set operating point. Yo = Auto can also be set, in this case no parameter control takes place but the operating point is set automatically in nonautomatic operation (see operating point in P-controller). Yo. to Yo.9 must either be set all = Auto or all Auto. Otherwise the error message Yo/Err appears when jumping out of the structuring mode PASt with the Exit key (see chapter.., page 75). Typical controlling variables are the control difference xd (it acts as jxdj) for progressive controls and x or y for operating point dependent controls (non-linear controlled systems). If S6 = 7 is set, a controling variable of % is simulated in Pi operation and a controlling variable of % in P operation. In this way you can work with large Kp (cp.) for example in P operation (control signal P=) to reach the operating point quickly. After switching to Pi operation (control signal P=) a reduced Kp (cp.) is active for a stable control. The parameter values and the value of the controlling variable can be gained by adaptation (see section Adaptation on the next page). SIPART DR 6DR C79-G7476-C

The adaptation procedure is far superior to manual optimization especially in slow controlled systems and in PIC controller types. It is activated by the operator and can be aborted at any time in the event of danger. The parameters determined by the adaptation can be changed and accepted specifically by the user. Non-linear control lines can also be mastered in connection with the parameter control. In the parameterization mode AdAP which is only accessible at S58, the following presettings are made for the adaptation procedure: tu Monitoring time dpv Direction of step command dy Amplitude of step command With the structure switch S58 the choice of the control behavior (with or without overshoot) is made. The adaptation principle is divided into line identification and controller design. Line identification The controller is driven to the desired operating point manually. By pressing the Enter key the set manual manipulated variable is changed by a step adjustable in the direction (dpv) and amplitude (dy). The y-step is output at the end of % of the set monitoring time (tu) if there was a fixed state of the controlled variable during this time. Otherwise there is an error message with abortion of the identification (see chapter.., table, page 77). 96 SIPART DR 6DR C79-G7476-C54-4

97 Manual Technical Description.5 Functional description of the structure switches.5.5 Control algorithm, parameter control, adaptation The step response of the controlled system is then accepted with a max. 84 value pairs (time and amplitude). The respective main controlled variable of the different control types is filtered adaptively (see figures -5, page 5 to figure -4, page 8) to use for controlled variable measurement. The measured values are read in with a scanning rate according to the cycle time. The noise level is suppressed by the adaptive filter. The storage procedure operates with cyclic data reduction and subsequent refilling so that slow controlled systems can be entered. After the start ID has been run through (the controlled variable x must have left the start ID band within 5% of the set monitoring time tu), 95% of the full range must have been reached at the latest at / of tu. The set monitoring time (tu) must be T95 of the controlled system with safety reserve. The remaining time is required for the full scale identification. The full scale identification can also take place immediately after the start identification, but / of the performed measurements are always required for the full scale identification. Recording of the measured value pairs is ended on identifying the full scale. A comparison with the recorded transient function is now made based on the stored Ptn models with n = to 8 and equal time constants T by variation of n and T. The determined line gain ks is transfered to the line models. The comparison is made over the minimum error area F (n, T) Additionally a special entry of real dead times is made which then shifts the identified control line to higher orders. Control lines with compensation and periodic transient of st to 8th order with a transient time T95 of 5 s to h can be identified. Dead time parts are permissible. In S-controllers the transient time T95 should be twice the positioning time Ty. SIPART DR 6DR C79-G7476-C

Acknowledgement of the error messages, see table - Error messages of the adaptation procedure, page 77. Controller design The controller is designed according to the amount optimum method (S58=). This setting method is very robust and also allows variation of the line amplification. However, it generates an overshoot of approx. 5 % in the event of changes in the command variables. If this is not wanted, you can also work with the controller design without overshoot (S58 = ), Kp is reduced here to 8 %. The controller is designed for PI and PID behavior, therefore kp, tn and for PID tv are calculated, whereby the derivative action gain is fixed at 5. A prerequisite is that the D-element is connected with xd or x (S55 = or ). In S-controllers the response threshold AH is calculated in addition to kp, tn, tv. The parameters ta, te and ty must be set beforehand according to the actuating drives used (see chapter 4., page 8). If the transient time T95 is near to ty (floating time) overshooting may also occur in controller designs with D-part at S58=. 98 SIPART DR 6DR C79-G7476-C54-4

S = : Continuous (K) controller (Fig. -56, page and fig. -57, page ) For activating P-action usually pnemumatic final control elements or as a master controller in cascades. In the K-controller the automatic manipulated variable ya of the controller I can be processed directly without further conversion. The manipulated variable y is followed by two split range-outputs y and y for actuator operation. The manipulated variable y is divided into two individual manipulated variables adjustable by the parameters Y and Y (structuring mode ofpa). Via S65 you can select the split range functions rising falling (y actuator heating y actuator cooling) or rising rising (y actuator control range y actuator control range ).

Depending on the design of the cooling and heating aggregate, related to the control range of the controlled variable, the different line gains can be compensated by different slope settings and good control results achieved in both branches.

The manipulated variable display at S67= is made for the outputs y and y by an ID I and II.

In the off position, no limiting takes place, in positions to s the minimum floating time for to % manuipulated variable is preset. The P, I and D part as well as the disturbance variable Z is limited in the rise speed. This positioning speed limiting is always used when the following final control element has floating times > s to prevent integral saturations or when the process cannot stand the hard impacts of the P, D or Z-part. In this case it must be taken into account that the control time is greater. At S6 = (incremental preset of YN) ty is used for the positioning speed setting of the integrator. The floating time for to % change is preset. In the off position the integrator output changes suddenly. SIPART DR 6DR C79-G7476-C54-4

S = : Three-position step (S) -controller with internal feedback To control I-acting motorized actuating drives. In S-controllers with internal feedback the K-controller is followed by an internal position controller. The positioning control circuit consists of a comparator with following three-position switch with hysteresis and an integrator in the feedback. The I-function of the actuator is simulated by the integrator with adjustable floating time ty (parameterization mode onpa) which replaces the position feedback. To ensure the internal integrator and the K-controller output do not drift apart or into saturation in time, both are set back rhythmically by the same amount (synchronized). The y-output is only a relative manipulated variable (y ). It is therefore not possible to perform a manipulated variable limiting of ya and an absolute value preset of ye and ys. The safety manipulated variable ys is preset as a direction-dependent continuous contact. At YS < 5 % (ofpa), Δy switches,atys 5 %, Δy switches to continuous contact so that the end positions represent the safety position. The position controller has an adjustable minimum pulse length (te) and pause (ta) with which the response threshold of the position controller is set indirectly: Switching on A ee = Switching off A ea = % te ty % te ty Hysteresis A ee A ea = % te ty Pause A a = % ta ty ty set floating time (parameterization mode onpa) After a pulse pause A ee must be set up at least as a deviation until an actuating pulse with length te is output. A ea can remain as a constant control error of the position control circuit. A a can be set up after an actuating pulse as a deviation until an actuating pulse is output in the same or opposite direction. When time ta has expired, the position controller reacts accordingly to the set te. Setting criteria of ta and te, see chapter 4., page 8. The position feedback y R via FE6 is only used to display the manipulated variable in S-controllers with internal feedback. If it is not connected, S67 is set to, the y-display (4) is then dark. 4 SIPART DR 6DR C79-G7476-C54-4

107 Manual Technical Description.5 Functional description of the structure switches.5.6 Controller output structures (S, S6 to S68).5.6. S = : Three-position step (S) controller with external feedback To control I-acting motorized actuating drives. In S-controllers with external feedback the internal position control circuit is replaced by a real position controller (with the K-controller output y as a setpoint and the position feedback yr via FE6 as an actual value). As a result a manipulated variable limiting of ya and an absolute value preset of ye and ys are now possible. With the absolute value preset of ye it is also possible to preset the manual manipulated variable via the SES as an absolute value yes in follow-up operation. If y E is preset via the follow-up input yn (FE5), the freely connectable input range (S4=) must be used because in the permanently connected input range, FE5 is not available at S= (see fig. 4). Here too the response threshold of the position controller is preset with the parameters te (minimum turn-on duration) and ta (minimum turn-off duration) in connection with ty (floating time). Switching on A ee =4 Switching off A ea = Hysteresis A ee A ea = Pause A a = % te ty % te ty % te ty % ta ty If a control deviation of xds A ee is set up, the three-position switch switches direction-dependently to continuous contact. xds is reduced by the negative follow-up of the position control circuit until xds <A ea is reached. The continuous contact is now switched off. After the pause time ta pulse of length te are output with subsequent pause time ta until xds A ee is reached. Δy -Aea-Aee Aea Aee -Δy xds These single pulses are also output if xds coming from zero does not reach A ee. These single pulses which are not fully transformed into the path change (rotational movement) additionally calm the control circuit, i.e. in theory (without lag) the single pulses would switch off at.5 or.5 A ee. The opposite direction can only occur at appropriate control deviation after the pause time ta. The control difference of the position control circuit xds can be measured at assigmment to an analog output. Manual adjustment via the front panel is made at S67= here too as an incremental adjustment by overmodulating the three-position switch so that manual adjustment is possible even when the position feedback is interrupted. To simplify commissioning of the position control circuit, the manual manipulated variable is preset absolutely at S67= (manipulated variable of the K-controller) so that the setpoint of the position control circuit is changed continuously in this structure switch position to enable optimization (see chapter 4.). It should be taken into account here that the manual SIPART DR 6DR C79-G7476-C54-4 7

108 Technical Description.5 Functional description of the structure switches.5.6 Controller output structures (S, S6 to S68) Manual manipulated variable which is also displayed is changed faster by the floating time than the active manipulated variable on the actuator and a lag therefore takes place. The controlling status can be monitored on the Δy-LEDs (5) in the y-display. After optimization, S67 should be set to to display the active manipulated variable via the position feedback y R (FE6). 8 SIPART DR 6DR C79-G7476-C54-4

All other control signals He, N (DDC), Si and ybl must be. The automatic manipulated variable is connected through to the controller output. Manual mode (y=y H) Manual operation is switched on by the Automatic/Manual key (yellow manual LED(8) an) or the control signal He as an OR function. The control signals Si and ybl must be. If follow-up operation has priority over manual operation (S6=), the control signal N (DDC) must also be. The manual manipulated variable is through connected to the controller output. The manual manipulated variable is preset in K-controllers as an absolute value, in S- controllers as a positioning increment. Follow-up(DDC) mode (y=y E) The follow-up mode is switched on by the control signal N (in DDC mode by the control signal CB and the Internal/External key.5.4, page 4). The control signals Si and ybl must be. If manual mode has priority over follow-up mode (S6=) the control signal H=Hi v He must be. The external manipulated variable y E is connected through to the controller output. The source for y E is preset at S = or as an absolute value (y N ) via the function input FE5 (S6=) or as an external manipulated variable with incremental adjustment by the control signals Δy (y N Δ ) (S6 = ). The incremental adjustment runs at the adjustment speed %/ty. With S = the absolute value becomes active as an external manipulated variable via the SES (y ES ). In Scontrollers with internal feedback (S = ) absolute value presets of the manipulated variable are not possible, only the external manipulated variable with incremental adjustment (y N Δ) is available. Safety operation (y = y s) The safety operation is switched on by the control signal Si. The control signal ybl must be. The safety manipulated variable y s is through conencted which can be set as a parameter in the structuring mode ofpa in the range from to %. In Scontrollers with internal feedback (S = ) absolute value preset is not possible. When safety operation is active the output at YS<5 % is Δy continuous contact and at YS 5 % Δy continuous contact so that the actuator moves to the end positions. Direction dependent blocking operation Blocking operation is controlled by the control signals ybl. All other control signals have no function. If a control signal is applied the manipulated variable output is blocked direction-dependently, i.e. only changes in the opposite direction are allowed. If both control signals are applied simultaneously, the output is blocked absolutely. The direction-dependent blocking is necessary especially in S-controllers with internal feedback and actuators with limit stop switches to avoid integral saturation. If the control circuit is opened on reaching the end position of the actuator, further integration of the controller must be prevented in order to be able to react immediately in the event of control difference reversal.

113 Manual Technical Description.5 Functional description of the structure switches.5.6 Controller output structures (S, S6 to S68) As described above, the control signals ybl have priority over Si and H or N. Priority of H or N can be selected via S6. All these operating modes have priority over automatic operation. Signaling of the switching states is made by the LEDs Manual (8) and y-external (). If manual operation is active or preselected (if the prioritized operating modes are active), the Manual LED lights up. He = (via control signal) is signaled by a flashing rhythm of 9.9 when Hi = (via Manual/Automatic switch i.e. is in automatic operation). When switching the control signal He from automatic operation becomes active. Follow-up (DDC), safety and blocking operation is signaled by the y-external LED. Flashing rhythm.5 indicates that in manual operation priority over follow-up operation, manual operation is active but follow-up operation is prepared and after switching to automatic operation also becomes active. Blocking of the manual/automatic switching (S64) With S64 Manual/Automatic switching can be blocked in the operating modes only automatic or only manual (see figure -6, page 7). The other operating modes are still possible. The follow-up operation only if follow-up has priority over manual operation. Manual mode in event of transmitter fault S6 With S6 it is possible to switch to manual mode when the transmitter group fault message occurs (see chapter.5., page ). Manual operation starts at S6= with the last y or at S6 = with the parameterized YS. In both cases the manual manipulated variable can be adjusted with the Δy keys after switching. Source and direction of effect of the y-display S67, S68 With S67 the y-display is switched to the different display sources or switched off. The absolute manipulated variable y or the split range manipulated variables y and y can be displayed in K-controllers or the position feedback message/command signal y R via FE6 in S-controllers. With S68 the display direction rising falling can be selected (see chapter 4.). Control system coupling via the serial interface In addition to the DDC controller (S = ) the SPC controller (S = ) a complete parallel process operation is possible in all controller types via the serial interface. The control signals Int and Hi (via HeES at S64 = /4, see chapter.5., page 4) and the process variables wi and yh can be written at S via the serial interface so that switching from internal to external setpoint and Automatic/Manual switching is possible in all controller types. If the internal setpoint wi or the manual manipulated variable yh is active it can also be changed by the SES or the adjusting keys on the front panel. Since the SES can only adjust absolutely and not incrementally, it is advisable to use the setpoint ramp (ts) or the dynamic manipulated variable with ty to avoid steps. This parallel front operation via the serial interface can be locked at S64 = via RC = Int CB (see chapter.5.). This locking facility for the operation via SES on the controller front is only useful in the controller types fixed setpoint controller with a setpoint (S = ) and follow-up controller without Internal/External switching (S = ) because in all other controller types both the Internal key and the control signal CB have other additional SIPART DR 6DR C79-G7476-C54-4

114 Technical Description.5 Functional description of the structure switches.5.6 Controller output structures (S, S6 to S68) Manual functions. At S64 = 4 this locking facility is omitted and operation is always parallel to the front keys. To avoid simultaneous actuation by the controller front and the SES the last switching action can be read both on the process control system and the controller. For this, a status bit is set when writing IntES and HeES which is only reset when the front keys Int or Hi are actuated. By requesting the status bit, the process control system can issue a warning when the last operation took place via the front. If the last operation took place via the SES the warning SES flashes for s in the x/w display when the Internal key or the Manual key is pressed. This initial pressing of the keys does not activate a switching function, only when the keys are pressed again is the desired switching function triggered. Output structure controller II at S = With S = a second parallel independent control channel is released. Operation and monitoring of both control circuits take place on two levels which are selected with the Shift key and signaled by the displays I or II. The functions of the output structure of the controller II correspond to those of the controller I; only exception: incremental manipulated variable adjustment is not possible. The effect of the respective duplicated structure switches and parameters can be seen in the following block diagrams. 4 SIPART DR 6DR C79-G7476-C54-4

When using option modules in the slots 5 and 6 the structure switches S and S are set according to the assembly, other settings lead to error messages (see chapter.4., page ). The control signals Δy (positioning increments of the S-controller) are not assigned and not negatable. When structuring S-controllers (S = or ) they are always at BA7 and BA8, i.e. BA7 and BA8 can only be assigned freely in K-controllers (S = ).

123 Manual Technical Description.5 Functional description of the structure switches.5.8 Digital output signal processing (S76 to S9 and S58 to S66) Functional explanation of the digital message signals RB RC H N No computer standby of the controller This signal indicates that the controller is in internal operation, i.e. not in computer standby. In cascade controllers (double controllers) this signal relates to the master controller, in override controls to the main controller. No computer operation This signal indicates the negated computer operation RC = Int CB and controls the setpoint switching or the DDC operation. In cascade controllers this message relates to the master controller, in override controls to the main controller. Manual mode The controller is in manual mode, triggered either by manual/automatic switching on the front of the controller (Hi) or by the binary signal He if the control signals Si, ybl and N (with follow-up over manual operation priority) are Low. Follow-up mode The controller is in follow-up mode when the control signals Si, ybl and H (in manual over follow-up operation priority) are Low. A/A Alarm and indicate response of the limit value alarms A and A. A/A4 Alarm and 4 indicates response of the limit value alarms A and A4. MUF IntI Δy Transmitter fault The analog input signals of the controller can be monitored for exceeding of the range. This signal gives a group alarm if an error is detected. Internal operation of the slave controller This signal indicates that the cascade in cascade controllers (double controllers) is disconnected to Internal by Internal/External switching of the follow-up controller. Position increments for the Δy-adjustment in S-controllers Message signals RBII, RCII, HII, NII, IntII, ΔyII are only active at S= and have the same meanings for controller II as above.

With S67 = or S68 = (factory setting), the limit value alarms A, A or A, A4 are combined as pairs. In this case the assignment only takes place with S94 or S95, only hysteresis H. or H.4 are active. With S96 (A, A) or S97 (A, A4) the monitoring function Max/Min, Min/Min, Max/Max, Min/Max can be set. The response thresholds A to A4 and the hysteresis H., H.4, H., H4. can always be set in the structuring mode ofpa. According to the switch position of S98 only the display or the display and adjustment of A to A4 is possible in the process operation level. In this case the switching cycle of the Shift key () is extended by the response thresholds A to A4, displayed on the y-display (4): Controller I Controller II -A-A-A-A4ControllerI... The response thresholds are set depending on the assignment physically corresponding to the display format of the digital x or w display (see chapter.5.4, page 4) or in %: S S94, S95 S67, S68 assigned to Display format Parameter range 4 6 xdi xi wi according to dai bis dei -999 to 9999 maximum - % to % related to dei -dai = % 4 and 6 4 xdi xi wi xv wv % % % according to dai bis dei -999 to %to% maximum - % to % related to dei -dai = % 5 to xdii xii wii according to daii bis deii -999 to 9999 maximum - % to %relatedtodeii -daii = % to 8 # 7 y # FE % -%to% Table - Display format of the limit values A to A4 The hysteresis H., H.4, H., H4. is set in % in the range from. to %.

Restart conditions (S99, S) With S99 the restart conditions after mains recovery and manual reset are determined. In position the controller starts after mains recovery and after a watchdog reset with the operating mode and with the y which was active before the power failure. This variation must be used when temporary mains failures are to be expected in slow control circuits. In position start takes place after mains recovery in manual and Internal operation (in cascades also with IntI) with ys in the K-controller and with the last y in the S-controller. If only external operating mode or only automatic operation was selected by the structuring, the restart takes place in these operating modes. With S the optical signaling of mains voltage recovery and reset is determined by flashing of the digital x-display. The flashing is acknowledged by pressing the Shift key () or by an alarm request via SES..5. Serial interface and PROFIBUS-DP (S to S7) With S the depth of the SES interventions is preset. Generally all available set data can be read. In position no transmission and reception of data to the controller is possible. In position only parameters and structures can be transmitted. In the other positions the process variables wes (external setpoint via the SES) and yes (external manipulated variable via the SES) and all control signals can be transmitted by the SES. In this position the other possible sources for the external setpoint or the external manipulated variable are switched off. The structure switches S to S7 determine the transmission procedure through the serial interface.

143 Manual Installation. Mechanical Installation Installation. Mechanical Installation D Selecting the Installation Site Maintain an ambient temperature of to 5 _C. Don t forget to allow for other heat sources in the vicinity. Remember that if instruments are stacked on top of each other with little or no gap between them, additional heat will be generated. Front and rear sides of the controller must be easily accessible. D Panel mounting The SIPART DR is installed either in individual panel cutouts or in open tiers (for dimensioned diagram, see chapter.6., page 8 fig. -7, and fig. -7). The upper edge of the panel cut-out must be left unpainted to ensure good interference suppression of the controller even at high frequencies. A good HF ground connection is established by the contact spring protruding from the top of the SIPART DR. If necessary: Push self-adhesive sealing ring for sealing front frame/front panel over the tube and stick to the tube collar (see chapter 5., page, item.6). Insert SIPART DR into the panel cut-out or open tier from the front and fit the two clamps provided to the controller unit from the rear so that they snap into the cut-outs in the casing. Align SIPART DR and do not tighten the locking screws too tight. The tightening range isto4mm.. Electrical Connection The arrangement of the connecting elements can be seen in fig. -, page 45. WARNING! The Regulations for the installation of power systems with rated voltages under V (VDE ) must be observed in the electrical installation! D PE conductor connection Connect the PE conductor to the ground screw (see figure -) on the back of the controller. When connecting to 5 or V AC mains supply, the PE conductor can also be connected through the three-pin plug (see figure -). The controller s ground connection may also be connected with the PE conductor (grounded extra low voltages). SIPART DR 6DR C79-G7476-C54-4 4

144 Installation. Electrical Connection Manual WARNING! Disconnection of the PE conductor while the controller is powered up can make the controller potentially dangerous. Disconnection of the PE conductor is prohibited. D Power Supply Connection The power supply is connected on 5 V or V AC systems by a threepin plug IEC /V DIN A, on 4 V UC systems by a special pin plug (polarity irrelevant). The plugs are supplied with the unit. WARNING! Set the mains voltage selection switch (see figure -) in the novoltage state to the existing mains voltage. It is essential to observe the mains voltage specified on the rating plate or on the mains voltage switch (5/ V AC) or on the voltage plate (4 V DC)! Feed the power cables via a circuit breaker within easy reach (fire safety according to IEC 66E (sec) /DIN VDE 4 Part ). When connected to an unprotected power supply, the controller must be supplied via a circuit breaker. The circuit breaker is not required if one already exists ( Vrms or 4,4 V DC and current 8 A or source under all load conditions 5 VA or fuse element which responds at 5VA). The circuit breaker can be omitted if the 4 V UC power supply is protected by 4 A (5 V DC) (T,5 A is required at least). D Connection of measuring and signal lines The process signals are connected via plug-in terminal blocks that can accommodate cables of up to.5 mm (AWG 4) cross-section. Standard controller Slot 4- and -pin Option modules Slots and 4-pin Slot 5 and 6 5- and 6-pin Interface relays Slots 7 and 8 - and 6-pin The slots to 8 must be marked in the circuit diagrams and at the terminal blocks. Signal lines should be laid separately from power cables to avoid the risk of interference couplings. If this is not possible, or due to the type of installation the controller may not function properly as a result of interference on the signal lines, the signal lines must be shielded. The shield must be connected to the PE conductor of the controller or one of the ground connections, depending on the fault source s reference junction terminal. The shield should only ever be connected to one side of the controller when it is connected to the PE conductor to prevent creation of a ground loop. 44 SIPART DR 6DR C79-G7476-C54-4

145 Manual Installation. Electrical Connection The SIPART DR is designed with a high electromagnetic compatibility (EMC) and has a high resistance to HF interference. In order to maintain this high operational reliability we recommend that all inductances (e.g. relays, contactors, motors) installed in the vicinity of or connected to the controllers should be assembled with suitable suppressors (e.g. RC combinations)!

If these GND connections are not sufficient, additional proprietary terminals can be snapped onto the DIN rail on the power pack. The controller uses a common reference for both inputs and outputs, all process signals are referred to this point. The reference line is also connected to vacant terminal modules. These may only be used if practically no current flows through this connection (see e.g. fig. -, page 5, I 4L). The power supply connection is electrically isolated from the process signals. In systems with unmeshed control circuits, the SIPART DRs need not be interconnected. In meshed control circuits the GND connections of all controllers must be fed singly to a common termination or the continuous GND rail with a large cross-section. This common termination may be connected with the system s PE conductor at one point. Since in analog signal exchange between the devices, only currents /4 to ma are used and these are evaluated as a four-pole measurement (differential amplifiers with electronic potential isolation), voltage drops on the M-conductor are not interpreted as errors (see fig. -6, page 59 to fig. -). The signal-to-noise ratio on digital signals is so great that voltage dips on the GND rail can be ignored. 46 SIPART DR 6DR C79-G7476-C54-4

167 Manual Operation. Process operation Operation The SIPART DR is operated exclusively and fully with the operating keys on the front module. The function of the operating panel can be switched between three main levels: Process operation level Selection level Configuring level (structuring and parameterization modes) Some of the keys and displays on the front module are assigned different control and display functions when the operating mode is changed. See the description of the respective main level for details.. Process operation The operation of the SIPART DR in process mode requires no detailed explanation due to the design and colour scheme of the operating panel, the control elements and the labeling. (Fig. -): Red is the color of the actual value: The four-digit red digital display (6) and the red vertical LED bargraph (7) display the actual value. Green is the color of the setpoint: The four-digit green digital display (9) and the green LED bargraph (8) display the setpoint. The green Internal/External key () is used to switch between the internal and external setpoint, the internal setpoint is set with the green w-adjusting keys (6). The green internal LED () signals operation with the internal setpoint, the C-LED () also lights green when there is no CB control signal. Yellow is the color of the manipulated variable: The yellow H/A key is used to switch between manual and automatic operation. The yellow manual LED (8) signals by lighting steadily or flashing that manual operation has been activated. Lighting up of the yellow y-external LED () signals an external intervention in the manipulated variable, i.e. a follow-up (DDC), safety or blocking operation. The manipulated variable generally displayed in the yellow digital display (4) can be adjusted with the yellow y-keys () in manual operation. The yellow y-leds (5) indicate the output of the adjusting increments in all operating modes of the S-controller. The alarm LEDs (5) and (7) signal exceeding or dropping below of the limit values. The adaptation LED (4) signals the progress of the parameter optimization during the adaptation process by lighting steadily or flashing. The displays and setpoint keys in the double controllers are switched over by the Shift key () with which the displays can also be switched to different signal levels in single controllers. The corresponding controller LEDs () signal the switching state. The measuring point label () is exchangeable. To change it, open the plexiglass cover with a pointed tool in the center and take out the label. Behind it a screw is revealed which can be used to separate the front module from the controller (see chapter 5, page 7 Maintenance ). SIPART DR 6DR C79-G7476-C54-67

172 Operation. Configuring level (parameterization and structuring mode).. Paramterization Manual. Configuring level (parameterization and structuring mode).. Paramterization Parameterization including the selection level takes place online, i.e. the controller continues operating in its last operating mode. The analog x-display (7) and W-display (8) still displays the process image so that the reaction of the controlled system to parameter changes can be read off directly. The Internal LED () and Manual LED (8) and the Alarm LEDs A to A4 indicate the current operating state. The Internal/External key () becomes the Exit key, the corresponding C-LED () indicates ready to exit, i.e. whenever the LED flashes, pressing the Exit key returns from the selected level to the higher level in the hierarchy. The w-keys (6) serve to adjust the variables displayed in the digital w-display (mode name or parameter value). The Automatic/Manual key (9) becomes the Enter key, the corresponding y-external LED () indicates ready to enter, i.e. whenever the LED flashes, pressing the Enter key causes a jump down to the next level in the hierarchy. The digital x-display still indicates the controlled variable x except in mode AdAP (see chapter.., page 75). The y-keys () serve to adjust the parameter name displayed in the y-display. In double controllers the remaining process displays can still be switched over to the controllers not selected in the process operation level with the Shift key () but now only for as long as the Shift key () is pressed. The extension of the switch over cycle by A to A4 which may have been selected with S98 is suppressed. The discrepancy signaling by the controller I /controller II LEDs () is not changed with this switchover. Therefore the controller with the unlit controller LED (steady or flashing light) is always displayed whilst the Shift key is pressed. The parameters with a large numeric range can be adjusted rapidly in the parameterization modes onpa and AdAP.

175 Manual Operation. Configuring level (parameterization and structuring mode).. Parameterization mode AdAP (Adaptation).. Parameterization mode AdAP (Adaptation) This mode only appears in the parameterization preselection level when S58 (with adaptation). The Enter function into the parameterization mode AdAP is only possible when the controller is in manual operation (when adapting the master controller in cascades (S = 5/6) only in internal and automatic operation of the master controller). In the parameterization mode AdAP, the controller influences the process online (but in manual operation). In double controllers (cascade, ratio cascade and override controllers), adaptation is always made to the controller selected by the Shift key () in the process operation level. The remaining process displays can still be switched over to the controllers not selected in the process operation level with the Shift key () but only for as long as the Shift key () is pressed. Steady or flashing lights in the controller I/controller II LEDs signal the adapted controller. In override controllers (S = 7/8) the flashing controller LED signals that the other controller would be active in automatic operation. The parameterization mode AdAP has 4 different states: Pre adaptation During adaptation Aborted adaptation Post adaptation The digital display and the keys are assigned different functions in the individual states which are integrated smoothly in the operating concept of the controller. In pre- and post-adaptation the digital displays and the keys are used for the parameter display and -setting as is the case in the parameterization mode and structuring mode onpa or ofpa (see figure -6, page 79). The complete process image as described in chapter., page 67 is displayed during adaptation (see figure -7, page 79). In the case of aborted adaptation the error message flashes in the digital x- and w-displays. The error messages are acknowledged with the Enter key (9) (see figure -7). D Pre adaptation The adaption LED (4) is off and indicates readiness for adaptation. First the parameters for the presettings (tu, dpv, dy) are displayed. They must be set according to the desired step signal. Then the old parameters **.o with the ID Pi or Pid with their value and the new parameters **.n with the ID Strt AdAP appear on the displays. If there is parameter control (S59 ) PAST is displayed as a note in place of the value when **.o. The old and the new parameters are not adjustable. The adaptation can only be started with the Enter key (9) when the new parameters **.n are selected with the display Strt AdAP (manual operation is a prerequisite). SIPART DR 6DR C79-G7476-C54-75

176 Operation. Configuring level (parameterization and structuring mode).. Parameterization mode AdAP (Adaptation) Manual D During adaptation The adaption LED (4) flashes indicating that the adaptation is in progress. The process can be monitored over the whole process display. D Aborted adaptation The adaptation LED (4) is off indicating readiness for adaptation after error acknowledgement. The current adaptation can be aborted manually or automatically by the error monitor. Manual abortion can be activated in the event of danger by pressing the Exit key (). The program then jumps to the parameterization preselection level after AdAP. From there you can return to the process operation level by pressing the Exit key () again. The controller is in manual operation and the manual manipulated variable can be adjusted. Automatic aborting is effected by the error monitors. The error messages are displayed on the digital x- and w-displays. The error message is acknowledged by pressing the Enter key (9), the parameterization mode AdAP is retained, tu is displayed, the presettings can be corrected if necessary. The adaptation is aborted by the signals N (DDC), Si and ybl. Abortion by the SES control signals N ES (DDC), Si ES, ybl ES can be prevented by Internal operation. D Post adaptation The adaption LED (4) is on indicating the end of adaptation. The parameters **.o with the ID Pi or Pid and the new parameters **.n with the ID Pi. to 8 and Pid. to 8 for Pi and Pid controller design are offered. The digits after the Pi or Pid ID indicate the determined line order. If there is parameter control (S59 ) the old parameters **.o are displayed with PAST instead of the parameter value. The old and new parameters are adjustable but the new parameters only if there is no parameter control. On pressing the Exit key the parameters **.o or **.n just selected are transferred when returning to AdAP in the parameter preselection level. The LED (4) is now off. When transfering **.o, these parameters remain unchanged if they have not been changed manually. When transfering **.n the old parameters are overwritten by the new parameters. The new parameters are deleted, i.e. after jumping back to the parameterization mode AdAP, the **.n parameters are identified by Strt AdAP. The transfered parameters do not affect the process until the process operation level has switched to Automatic after pressing the Exit key (). When the Exit key () is pressed with parameter control ( **.o PAST) and selection of **.n, the error message no AUto appears (see fig. -5, page 78). It indicates that no automatic transfer is possible, the **.n parameters and the controlling variable SG must be noted down (see chapter.5.5, page 96 Adaptation ). 76 SIPART DR 6DR C79-G7476-C54-

202 Operation. Configuring level (parameterization and structuring mode)..8 Structuring mode FCon (connect functions, connection) Manual..8 Structuring mode FCon (connect functions, connection) In the FCon mode (only appears when S4 = ) the functions defined with YES in the FdEF mode are connected (software connected ) with each other and with the selectable inputs and outputs (FE to FE) of the freely connectable range. A connection is made by setting a data source/data sink pair on the digital x and y display. The data sink (question) is always set first followed by the data source (answer). The connection is established when switching to the next data sink or returning to the structuring preselection mode FCon. The data sinks (inputs of the functions and the outputs of the freely connectable range) and the data sources (outputs of the functions and inputs of the freely connectable range) are stored in the listed order. The data sources and sinks of the functions defined by no are hidden. Every data sink can only be assigned exactly one data source whereas every source can be connected with as many sinks as you like. The parallel loop of inputs (sinks) is therefore achieved by connection of the respective inputs with the same output (source). The presettings of the inputs (ncon or numeric values) specified in the description of the various functions is transferred to the FCon mode and can be changed (overwritten) there if necessary. Changes in the FdEF, if FCon has already been carried out If functions defined by YES are overwritten by no after connection in the FdEF mode, the existing connection to the inputs and outputs of the functions overwritten by no is removed. The inputs (data sinks) fed by the output of the deleted function are identified by ncon (not connected). Error message ncon Err It is not permissible to end the connection with data sinks defined by ncon because the desired functions cannot run with undefined inputs. If the structuring preselection level is to be left with the Exit key and some data sinks (inputs) are still defined by ncon, the flashing error message ncon Err appears and the structuring preselection level is not exited, the error can be corrected (Enter key) or ignored (Exit key). The error message is acknowledged by pressing the Enter key. It returns to the configuring mode FCon to the first data sink marked ncon, the error can be corrected. SIPART DR 6DR C79-G7476-C54-

205 Manual Operation. Configuring level (parameterization and structuring mode)..9 Structuring mode FPoS (position functions)..9 Structuring mode FPoS (position functions) In the FPos mode (only appears when S4 = ) the chronological order for processing the functions defined by YES in FdEF is determined. This chronolgical processing of the freely connectable range is inserted in the processing cycle of the controller at the right time. The position numbers to are called as questions and the positioning is established by assigning to a function (answer). Only defined functions appear in the answer cycle, already positioned functions are automatically deleted from the answer cycle. For positioning, the guideline applies that the input variables of a function have already been calculated before they have been processed. Since this requirement cannot be met, it must be taken into account that values from the previous cycle are used for operation in the case of feedbacks. If a positioned function is defined by no in FdEF, this function is deleted from the positioning list. The order for processing the other functions remains unchanged. The gap is closed automatically by shiting them together. Existing positioning sequences can be corrected with inst, delt and npos (in the answer cycle). D Function inst (insert) To insert a not yet positioned function in an existing positioning sequence. Set the position with y-keys () in place of which the not yet positioned function block is to be inserted. Set inst with w-keys (6) inst, the Enter-LED flashes and indicates the effectiveness of the Enter key. On pressing the Enter key (9), the set position number no** is defined by npos and the Enter LED goes out. The previous positioning series from no** is shifted up one position, the nr** can now be overwritten with the still free function. If the end of the positioning sequence is reached by the inst function (position number >), the function cannot be executed (Enter LED does not go out). D Function delt (delete) To close npos- gaps within a positioning sequence. Set the position number which is to be deleted with y-keys (). Set delt with the w-keys (6), the Enter LED flashes and indicates the effectiveness of the Enter key (9). On pressing the Enter key the set position number nr** is defined by the function of the following position numbers. The previous positioning sequence is moved down one position number from no**. D Function npos (not positioned) To exchange function blocks within a positioning sequence. Select the position numbers to be changed with the y-keys and mark respectively with npos. Then the functions overwritten with npos are available again in the answer cycle. They can be assigned to the position numbers occupied with npos. SIPART DR 6DR C79-G7476-C54-5

Determine direction of effect of the actuator Press the right manipulated variable adjusting key if possible with the process switched off or near to its safety position and observe whether the actuator opens or closes. If the actuator opens this means it has normal effect. If closing is determined in S-controllers, the connections y and - y should be switched.

217 Manual 4 Commissioning 4. Setting the split range outputs and the actuating time Note for cascade control In cascade controllers first the direction of effect of the followup controller is determined and set as described above if necessary. Then the direction of effect of the master controller is adapted to the system. This is done as described above. It must be noted that the followup controller has been switched to internal operation because manual adjustment of the master controller is performed by adjusting the setpoint of the followup controller. The display should be switched to the master controller with the Shift key () to observe the main manipulated variable. 4. Setting the split range outputs and the actuating time in K-controllers (S = ) D Split range outputs Y, Y In split range operation the two partial manipulated variables must be adapted to the control range of the individual final control elements with the slope setting so that as constant a system amplification Ks as possible is achieved over the whole setting range. Determine the system line amplifications in the partial setting ranges in manual operation. Ks= Δx andks= Δx Δy Δy Then set Y and Y so that at S65 = rising falling at S65 = rising rising % Y Y = Ks Ks Y % Y = Ks Ks D Floating time ty At S6 = : set ty to the floating time of the following actuating drive. If the control circuit is to be calmed additionally, e.g. to avoid hard impact on the actuating drive, ty can be further increased in Automatic operation. At S6 = : set ty to the desired floating time for the incremental follow-up variable. SIPART DR 6DR C79-G7476-C54-7

218 4 Commissioning 4. Adaptation of the S-controller to the actuating drive Manual 4. Adaptation of the S-controller to the actuating drive D S-controller with internal feedback (S = ) The floating time of the actuating drive is set with the online parameter ty ( to s); Attention:the factory setting is off! The online parameter te should be selected at least great enough that the actuating drive starts moving reliably under consideration of the power switches connected before it. The greater the value of te, the more resistant to wear and more gentle the switching and drive elements connected after the controller operate. Large values of te require a greater dead band AH in which the controller cannot control defined because the resolution of the controlled variable diminishes with increasing turn-on duration. The factory setting is ms for te. This corresponds to a y resolution in a 6 s actuating drive of: Δy = % te ty = % ms 6 s =.% The minimum possible resolution is transposed with the system line amplification Ks to the controlled variable: Δx =K s Δy The parameter ta (minimum turn-off time) should be chosen at least great enough that the actuating drive is safely disconnected under consideration of the power switches connected before it before a new pulse appears (especially in the opposite direction). The greater the value of ta, the more resistant to wear the switching and drive elements connected after the controller operate and the greater the dead time of the controller under some circumstances. The value of ta is usually set identical to the value of te. ta = te = to 4 ms are recommended for 6 s actuating drives. The more restless the controlled system, the greater the two parameters should be selected if this is reasonably justified by the controller result. According to the set te and the resulting y or x, the response threshold AH I must be set or for the controller II AH II. The following condition must be satisfied: AH I or AH II > x orah I or AH II > Ks te % ty Otherwise the controller outputs positioning increments although the control deviation has reached the smallest possible value due to the finite resolution. For setting of AHI or AHII see chapter 4.4, page 9. D S-controller with external feedback (S = ) The position control circuit is optimized with the online parameter ty. The same relationships apply as in the S-controller with internal position feedback whereby the dynamic of the position control circuit (non-linearities, follow-up) is added to the criteria of the processability of the positioning increments by the final control element. It will usually be necessary to select 8 SIPART DR 6DR C79-G7476-C54-

219 Manual 4 Commissioning 4.4 Setting the filter and the response threshold ty and the resulting response thresholds smaller than in the S-controller with internal position feedback for the above mentioned reasons. The position control circuit is optimized in manual mode. To do this, S67 is set to for the optimizing phase so that the manual manipulated variable is preset as an absolute value. It must be noted that the active manipulated variable trails the manipulated variable display due to the floating time of the actuator. In the case of non-linearity in the position control circuit, the optimization must take place in the range of greatest slope. Set S67 to Set ta and te so that the actuating drive can just process the actuating increments (see S-controller with internal feedback). Set st order filter of the y R -input (tf,,, 4 or 5) to. Ty (real floating time of the drive). Increase ty until the position control circuit overshoots due to small manual changes in the manipulated variable (observe opposite pulse on the y-leds (5) in the y-display). Reduce ty slightly again until the position control circuit is calm. Reset S67 to. 4.4 Setting the filter and the response threshold Set the structure switch S to the mains frequency 5 or 6 Hz existing in the system (factory setting 5 Hz) to suppress faults due to the mains frequency. D D Filter of first order of analog inputs The filter time constants (tf to tfb) for the input filters are set in the onpa parameterization mode and to the greatest possible value permitted by the control circuit without affecting the controlability (tf to tfb < Tg). When using the adaptation method the appropriate input filters must be optimized. Adaptive, non-linear filters of the control difference Since the dead zone sets itself automatically and its size is therefore unknown, the time tfi or tfii (onpa) can only be selected so great that the control circuit cannot oscillate in the case of a large dead zone (tfi or tfii less than Tg). When using the D-part (PD, PID) the use of the adaptive, non-linear filter is strongly recommended because the input noise amplified by Kp vv can be suppressed. When using the adaptation method the filters must be set. D Optimization of the response threshold AH If the controller output is to be calmed or the load on the actuator reduced additionally, the response threshold AHI can be increased for controller I or AHII for controller II. The response threshold AH is given in S-controllers by the setting of te (see chapter 4., page 8) and must be greater than zero. A response threshold of approx..5 % is recommendable for K-controllers. It must be taken into account that the remaining control error can assume the value of the set response threshold.

220 4 Commissioning 4.5 Automatic setting of control parameters Manual 4.5 Automatic setting of control parameters by the adaptation method The adaptation method should always be preferred to manual settings because the control results with the parameters gained from adaptation are better especially in slow controlled systems and this saves optimization time. D Presetting S58 selecting the control behavior (structuring mode Strs) No adaptation is possible when S58 =. In position a control behavior without overshoot is offered. In position changes in the command variables can be expected with a maximum 5 % overshoot. tu: Monitoring time (parameterization mode AdAP) tu is necessary for error messages only and has no influence on the identification quality. tu must be set at least double the transient recovery time T 95 of the controlled system. If you have little knowledge of the controlled system, use tu = off (factory setting) for adapting. After successful adaptation tu is automatically set to T 95. At tu <. h (6 min) tu = off is displayed. dpv: Direction of the step command (parameterization mode AdAP) The direction of the controlled variable change from the set operating point is selected with this configuring switch: x manual x = ks (y manual y). In controlled systems with batches it is recommendable to perform one adaptation with rising x and one with falling x. The averaged or dynamically more uncritical parameters can then be used for the control. dy: Amplitude of the step command (parameterization mode AdAP) The step command must be selected so great that the controlled variable changes by at least 4 % and the controlled variable change must be 5 times the average noise level. The greater the controlled variable change, the better the identification quality. Controlled variable changes of approx. % are recommended. D Notes on certain types of control for pre-adaptation Cascade control Double controllers are always adapted to the controller selected by the Shift key (). In cascade controls the sequence controller is adapted first in manual operation by selecting the controller I with the Shift key (). We recommend you to use the controller version without overshoot (S58=) so that the command behavior is uncritical. Then the master controller is adapted in internal and automatic mode of the follow-up controller. To do this, switch the folow-up controller to Internal on selecting the controller I (corresponds to manual operation of the master controller) and switch over to automatic operation, set the desired operating point by changing the setpoint if necessary. Then switch over to controller II (master controller) with the Shift key and start adaptation. The setpoint step of the follow-up controller is invisible for system identification. SIPART DR 6DR C79-G7476-C54-

221 Manual 4 Commissioning 4.5 Automatic setting of control parameters Ratio-cascade control When adapting the master controller in ratio cascades, the master process variable should not fluctuate too greatly otherwise additional changes in this controlled variable may occur at a constant ratio factor (v v) due to the control dynamic of the ratio controller (follow-up controller) and non-linearities between the ratio factor and the controlled variable of the master controller. These additional changes in the controlled variable would falsify the adaptation result because only changes by the ratio factor are to be measured. Override controls When selecting the operating point in override controls (including the y-step for the adaptation) it must be ensured that the limiting setpoint is not exceeded in adaptation of the limiting controller and the main controller. If the desired operating point cannot be attained due to the operating state of the system, the adaptation must be made at a level which comes closest to the later operating state. In the example explained in chapter.5.4.9, page 77, (core temperature control with casing temperature limiting) the maximum permissible casing temperature cannot be reached in adaptation of the limiting controller if the cooling water flow is not interrupted. Therefore adaptation must take place at a low level without exceeding the maximum permissible core temperature. In the other case, if the cooling water is switched off or fails, the maximum permissible casing temperature is exceeded, when adapted to the normal core temperature. In this case adaptation must take place at a low core temperature. Non-linear controlled systems In non-linear controlled systems several adaptations should be made at different load states. The adaptation results and the (previously selected with S6) controlling variable SG must be noted. The controlling variable is also read off in the parameterization mode AdAP in the range from to %. The parameter sets determined in this way, related to the controlling variable SG, are then entered in the structuring mode PASt (if necessary with interpolation). In this way ideal controller results can be achieved even on non-linear controlled systems. D Notes on the adaptation results D-part In S-controllers and K-controllers on controlled systems of st order the D part brings no noticeable advantages due to the finite actuating time ty or for reasons founded in the control theory. The disadvantages in the form of wear on the positioning side dominate. Range limits If one of the determined parameters reaches its range limits, the other parameter should be adjusted slightly in the opposite direction of action. If systems of the 8th order are identified the determined Kp must be reduced for safety reasons and if the control circuit is too slow (uncritical), then re-increased in manual optimization.
