12 Overview 1 Add 7 product line The Add 7 product line has add-on products for the cost-effective implementation of highperformance or specific process control and automation technology requirements. These products are based on extensive experience in process control and with the current system generation, 7, of the Siemens automation range "Totally Integrated Automation". As part of the Add 7 product line, the front-end module AddFEM covers the specific requirements for rapid turbine control. These include different signal types, redundancy, high-speed detection and preprocessing. Gas, steam, industrial and water turbine control can all be implemented with AddFEM. AddFEM can also be used to implement automation and control applications requiring rapid system responses. A wide and diverse range of technical combinations is possible with AddFEM. It can be used together with SIMATIC S7 and SIMATIC PCS 7 as well as with SPPA-T3000 or SIMADYN D. The AddFEM is controlled as a DP standard slave via the PROFIBUS DP bus system. The control and automation function is typically implemented in the automation processor. Additional AddFEM 6DL3100-8AC features compared to 6DL3100-8AA The AddFEM 6DL3100-8AC supports module redundancy, and/or you can edit the preprocessing functions on AddFEM. The AddFEM 6DL3100-8AC can be configured with DPV1 services during operation. 1.1 Design of the AddFEM The AddFEM combines the following in a stainless steel enclosure: Power supply Processors PROFIBUS DP interfaces Interfaces for process input and output signals Redundancy and service interface Switches and status displays 10 Operating Instructions, 04/2018, A5E C-08

15 Overview 1.3 AddFEM module assignment in PCS AddFEM module assignment in PCS 7 The analog AddFEM has analog and digital inputs and outputs and count pulse inputs for speed monitoring. The AddFEM can optionally be fitted with a preprocessing function (FEF) (software function). For the display and processing of the different AddFEM signal types in the higher-level host system PCS 7, the signal types are divided into logic modules as for a modular DP device with plug-in I/O modules. This division into logic modules corresponds to the numbering under the slot name in the hardware configuration, for example in HW Config. The pin assignment can be found in "Front connector assignment (Page 87)". Operating Instructions, 04/2018, A5E C-08 13

21 AddFEM area of area of application Classification and features Signal inputs and outputs The analog AddFEM has analog and digital inputs and outputs and count pulse inputs for speed monitoring. The arrangement of the different signal types and the optimized signal combination means that small applications can be handed by a single AddFEM. Multiple modules can of course be used for more complex applications. Each AddFEM has the following signal inputs and outputs: 12 analog inputs, of which 6 can be used as current inputs and 6 as either current or voltage inputs, configurable with SIMATIC Manager or COM-PROFIBUS. 8 analog outputs 15 digital inputs, of which 3 can be used as count pulse inputs for speed monitoring with and without rotational direction detection 16 digital outputs, which can also be used as digital inputs The measuring ranges of the analog inputs and outputs are designed in such a way that no additional signal transducers are required when the AddFEM is used for turbine control. Alongside the standard measuring ranges 0 to 20 ma, 4 to 20 ma and ± 20 ma for current inputs and outputs, a ± 30 ma measuring range is also available. An additional current range of ± 50 ma for the analog outputs allows actuators with higher power requirements, for example fuel control valves, to be controlled without additional signal amplifiers. Both analog and digital outputs are short-circuit-proof. All outputs are monitored and can be switched in parallel with other outputs. Analog and digital areas are electrically isolated from each another. More technical data on the inputs and outputs is available in "General technical specifications (Page 73)". Improving availability with redundancy Redundancy in this context means implementing a 1 out of 2 structure. Availability is increased by using two AddFEM in parallel. If one AddFEM fails following a fault, the second AddFEM takes over. With AddFEM 6DL3100-8AA, redundancy is configured on the automation processor. Redundancy control for the AddFEM 6DL3100-8AB/-8AC is an integral part of system performance on the AddFEM. A redundant link over a fiber-optic cable is used to transfer status and update information. Comprehensive redundancy mechanisms and integrated diagnostics functions in AddFEM ensure automatic error detection and switchover without any manual operations required. Operating Instructions, 04/2018, A5E C-08 19

22 AddFEM area of area of application 3.1 Classification and features Redundant PROFIBUS DP I/O The AddFEM has two PROFIBUS DP interfaces, DP A and DP B, which operate in parallel. This allows redundant system structures to be implemented. In principle, the process input information is managed in parallel over both PROFIBUS DP interfaces. However, only the process output information for the DP interface currently active is forwarded to the output pins. The process output information for the DP interface currently passive is analyzed for monitoring purposes. The master/reserve status of the two DP interfaces, i.e. which DP interface is active or passive in terms of output information, can be specified by the automation processor. Preprocessing functions Certain automation functions, such as positioners for turbine control, can be moved to the AddFEM as preprocessing functions. These preprocessing functions are known as front-end functions. GSD file When the AddFEM is used with SIMATIC S7 and SIMATIC PCS7, the PROFIBUS DP parameters and the properties of the AddFEM inputs and outputs (e.g. measuring ranges, filtering, etc.) can be set in the SIMATIC Manager using HW Config. When the AddFEM is used with SIMADYN D, the relevant settings are made with the COM-PROFIBUS software package. You will find information on using the GSD file in the "readme.pdf" on the AddFEM CD. Power supply The power supply for the AddFEM is designed for a rated power of 24 V DC. The typical power consumption is 20 W. Voltage dips of at least up to 10 ms are buffered. The inrush current is limited to 3 A. The 24 V DC load supply for the analog outputs is provided by the AddFEM. The 24 V DC load supply for the digital outputs must be generated externally and connected over connector X7. Design The AddFEM enclosure is made of stainless steel and is suitable both for screw mounting and for standard rail mounting. The signal states of the digital inputs and outputs are displayed by signal LEDs. The operation and error status of the AddFEM are displayed by 12 separate LEDs. The operating status is set with a key switch and a toggle switch. There are eight connectors on the front of the AddFEM, each with 10 pins (80 I/O pins in total) for connecting process input signals. 20 Operating Instructions, 04/2018, A5E C-08

23 AddFEM area of area of application 3.2 Additional features with version 6DL3100-8AC compared to 6DL3100-8AA/-8AB 3.2 Additional features with version 6DL3100-8AC compared to 6DL3100-8AA/-8AB The enhanced AddFEM DPV1 services are particularly suited to the acyclic supply of parameter data to front-end functions as required. This expansion also allows configuration changes to be made during operation (configuration in RUN). CiR allows the AddFEM to be reconfigured, for example to enable unused channels or reconfigure channels already in use when spare parts are fitted and a sensor with different specifications is used. It also allows alarms to be acknowledged with an implicit acknowledgment mechanism. This functionality can be used by front-end functions. PROFIBUS DPV1 The 6DL3100-8AC version (DPV1 slave) supports DPV1 services in accordance with IEC 61158, Part 3-6. The DP master must, of course, also meet these requirements (see DP master documentation). PROFIBUS DPV2 For switching communication redundancy (switchover between DPV1 channel A and DPV1 channel B), version 6DL3100-8AC supports the PrmCommand in accordance with PROFIBUS Guideline and outputs the redundancy status as a diagnosis. Operating Instructions, 04/2018, A5E C-08 21

24 AddFEM area of area of application 3.3 Driver blocks The table below shows the new functions of the AddFEM DPV1 slave: Function DPV0 slave 6DL3100-8AA/ -8AB DPV1 slave 6DL3100-8AC Cyclic data exchange X X Acyclic data traffic (read/write data record) DP master class 1 services (parameter assignment master) DP master class 2 services are not supported (e.g. SIMATIC PDM) Comment X AddFEM parameter assignment during operation. This allows parameter values to be supplied to the front-end function. Diagnostics Device-related diagnostics Identifier-related diagnostics Module status Channel-related diagnostics X X X X One interrupt can be output per diagnostic frame. Interrupts Diagnostic interrupt X Supports DS0/DS1. Manufacturer-specific interrupt X This interrupt can be used by a front-end function. Redundancy switchover Communication redundancy switchover for DPV1 channel A and DPV1 channel B. X Switchover with PrmCommand and redundancy status reported as diagnostics. The manual of the relevant FEF contains more information on configuration in the host system. The manuals for FEFs are available on the AddFEM CD in the directory for the corresponding article number. 3.3 Driver blocks Depending on the automation processor used, either the AddFEM can be controlled with driver blocks or, as for turbine applications with SYMADYN D, the AddFEM can be supplied with PROFIBUS frames straight from the user program. Driver blocks are available for SIMATIC PCS 7 and stored on the AddFEM CD in the "SIMATIC_PCS7_Driver" directory. 22 Operating Instructions, 04/2018, A5E C-08

25 Fitting AddFEM Overview The AddFEM fasteners can be modified. The AddFEM can therefore either be mounted on standard mounting rails or screwed to the wall. Both the lines for the 24 V DC module supply and the process cables are to be attached to the strain relief. Installable type in accordance with EN The AddFEM 6DL3100-8AA/-8AB/-8AC is "open equipment" in accordance with EN an "open type" in accordance with UL/CSA certification To fulfill requirements for safe operation with regard to mechanical strength, flame resistance, stability, and protection from contact, the following alternative types of installation are required: Installation in a suitable cabinet Installation in a suitable enclosure Only allowed in accordance with EN : Installation in a suitably equipped, enclosed operating area. WARNING Danger of burns to hands from hot surfaces The temperature rise in the metal enclosure at full load is approximately 20 K. At an ambient temperature of 60ºC, the temperature limit of 70ºC is exceeded. This limit represents the maximum temperature up to which contact without risk of injury is possible according to EN Do not touch the enclosure at ambient temperatures > 50 C without suitable protection. Operating Instructions, 04/2018, A5E C-08 23

26 Fitting AddFEM 4.2 Mounting options 4.2 Mounting options The following attachment options are possible: Mounting on double standard mounting rail (default configuration on delivery) Screw-mounting straight to the wall Standard rail mounting The center of the upper mounting rail must be mm from the center of the lower mounting rail. See section "AddFEM for standard rail mounting (Page 85)". To ensure that the AddFEM is firmly attached, the standard mounting rail must have a certain minimum stiffness. We therefore recommend a standard mounting rail in accordance with DIN EN with a thickness of 2.2 mm and spacing between fasteners of < 250 mm. For a rail length of 19 inches, this means that a central fastener is required as well as the fasteners at the sides. Requirement Slotted screwdriver, blade width 5.5 mm 24 Operating Instructions, 04/2018, A5E C-08

27 Fitting AddFEM 4.2 Mounting options Procedure Attaching the AddFEM Attach the upper fastening lug 2 from the top to the standard mounting rail 1 and "hook in" the AddFEM. Press the bottom fastening lug 4 against the standard mounting rail 3 until you can hear the fastening lug locking into place. The AddFEM is securely fastened. Removing the AddFEM Slide the slotted screwdriver, as seen in the figure, between the AddFEM and the bottom fastening lug. Turn the slotted screwdriver. This moves the bottom fastening lug against the spring pressure and the bottom standard mounting rail is released. Secure the AddFEM from dropping during removal. The AddFEM can now be lifted off the top. Operating Instructions, 04/2018, A5E C-08 25

28 Fitting AddFEM 4.2 Mounting options Screw mounting Ex factory, the AddFEM is ready for standard rail mounting. For screw mounting, you will need to turn the fastening lugs as shown in the figure below. For direct screw mounting, the fastening lugs on the back of the AddFEM need to be removed and refitted the other way round. 4 x M5 screws are used as fasteners. The spacing is shown in the dimension drawing in "AddFEM for screw mounting (Page 86)". 26 Operating Instructions, 04/2018, A5E C-08

29 Fitting AddFEM 4.3 Enclosure 4.3 Enclosure The AddFEM can be fitted in cabinets together with other distributed I/O devices or higherlevel processing units from the SIMATIC S7, SIMATIC PCS 7 or SIMADYN D range. A special cabinet construction from Siemens has been optimized specifically for these system lines. The cabinets, consisting of system-specific and system-neutral modules, are CE-compliant, i.e. they comply with the guidelines for electromagnetic compatibility set out in the German EMC Act [EMV-Gesetz]. They provide secure protection from unauthorized access, mechanical influences, contamination and corrosion. Thanks to their modularity and the variability this offers, the cabinets can be adapted to different types and sizes of plant. For contact persons for the configuration and design of customer-specific system cabinets, please see "Industry Services and Industry Mall, Digital Factory" in the Preface.

30 Connecting AddFEM Connecting the power supply Connecting the power supply for the AddFEM The AddFEM is supplied with 24 V DC over a connector on the front panel. 1 2 M: Reference potential L+: Power supply +24 V The AddFEM supply input is electronically limited. The AddFEM also has a 2.5 A fast-blow fuse. This is an internal safety fuse for preventing damage and cannot be changed. The AddFEM can be operated with a 19.2 to 30 V DC supply. The low limit 19.2 V is monitored. Connecting the load supply for the outputs The 24 V DC load supply for the analog outputs is provided by the AddFEM. The 24 V DC load supply for the digital outputs must be generated externally and connected over connector X7. For the pin assignment, see "Front connector assignment (Page 87)". 28 Operating Instructions, 04/2018, A5E C-08

31 Connecting AddFEM 5.2 Connecting ground and electrical isolation 5.2 Connecting ground and electrical isolation The following areas are isolated from each other: Microcontroller area including the analog inputs and outputs 24 V DC module supply Digital inputs and outputs 4 of the 12 digital inputs and the 3 count pulse inputs have a common reference potential. The 16 digital outputs are divided between two reference potentials. The grounding is sufficient if the module is mounted on a grounded standard mounting rail (standard rail mounting) or on a grounded panel (screw mounting). If the mounting is not sufficiently well grounded, grounding must be provided separately. For separate grounding, there is a grounding screw on the front panel below the module supply connection, which can be used to connect a grounded cable. For more detailed information on the installation of an entire plant (lightning protection, grounding, etc.), please refer to the SIMATIC PCS 7 documentation on the Internet, for example "Automation System S7-400, Hardware and Installation, Installation Manual". 5.3 Connecting interfaces Interfaces X1 and X2 Redundant interface X2 For redundant operation of two AddFEM. Service interface X1 For maintenance and commissioning. For AddFEM PoCo Plus, 6DL3100-8AC05, only, this interface is used as an additional redundant interface for channel-selective analog input redundancy switching for position feedback. PROFIBUS DP I/O X3A and X3B The AddFEM has two PROFIBUS I/O for communication with the automation processor. Process I/O X4 to X7 The process input and output signals are connected over sockets X4 to X7. The corresponding connectors for the X4 to X7 sockets have screw connections for wire crosssections of 0.14 mm 2 to 1.5 mm 2 (AWG 28 16). See also Design of the AddFEM (Page 10) Operating Instructions, 04/2018, A5E C-08 29

32 Connecting AddFEM 5.4 Connecting process cables 5.4 Connecting process cables Cable type Shielded cables must be used for analog signals to prevent interference. Unshielded cables can be used for digital signals. See "Operating safety standards (Page 90)" and "Electromagnetic compatibility (Page 91)". Front connector In accordance with UL/CSA approval for the front connectors for sockets X4 to X7 (connectors with 10 screw terminals from the AddFEM connector set, article number 6DL9900-8AA), the process signals must be connected either over solid copper wire lines or with stranded wires with wire-end ferrules. Stripped length: 9 mm Screw tightening torque for connecting wires: 0.22 to 0.25 Nm At an ambient temperature of 60 C, the temperature around the terminals can reach 70 C. Cable insulation must be approved for 75 C. WARNING Danger, high voltage Dangerous contact voltages caused by transients or incorrect connections can occur in the process and be transferred to the AddFEM over the connectors. These voltages can lead to death or serious injury in the event of contact. Do not touch any connectors on the AddFEM during the process. Contact by the user with these dangerous voltages is, for example, possible at the following points: Process connector locking screws Contact with the locking screws used to secure the cable cores to the process connectors is possible when attaching the cables or handling the connection plugs. Pins on the module front connector If the process connectors are only partially fitted to the module front connectors, dangerous contact voltages may be transferred by the module from the fully inserted pins to the pins still exposed. Keep the protective cover of the AddFEM closed in normal operation. If you open the protective cover, first disconnect the connection to the process or take suitable precautions to prevent contact with the open pins and locking screws. 30 Operating Instructions, 04/2018, A5E C-08

33 Connecting AddFEM 5.5 Pin assignment for process signals 5.5 Pin assignment for process signals The 4 connectors on the front panel are designed and numbered in the same way. The connector assignment is detailed in "Front connector assignment (Page 87)". The two connectors X4 and X5 are reserved for analog signals. The two connectors X6 and X7 are reserved for digital and speed monitoring signals. Of the 12 analog inputs, 6 can be used either as current inputs or as voltage inputs. The remaining 6 analog inputs can only be used as current inputs. The 16 digital outputs can also be used as digital inputs Of the 15 digital inputs, 3 can be used as count pulse inputs for speed monitoring with/without rotational direction detection. In speed monitoring with rotational direction detection, count pulse input 1 records the leading and count pulse input 2 the lagging signal. 5.6 Strain relief and support Cable strain relief On the front panel of the AddFEM is a metal strain relief rack for securing all the cables and lines with cable ties. If the module is to be changed, you can remove this rack with the cables and lines mounted to it by loosening the 2 screws, and then mount it on the new module. Securing the cable shields The shields for the cables for the analog signals and the shields for the PROFIBUS DP lines should if possible be secured and grounded just upstream of the module. If the cables are not grounded until the strain relief, any high-energy interference from the shielding will be discharged over the module enclosure and affect the module's immunity. Unshielded cables can be used for digital process signals. Operating Instructions, 04/2018, A5E C-08 31

34 Connecting AddFEM 5.7 Interconnecting process signals 5.7 Interconnecting process signals Ground reference All analog input channels are implemented as differential inputs. Each channel has its own input (ground for the individual channel) for the + signal input. This allows the current inputs of 2 AddFEM to be connected in series for redundant supply. Please note, however, that such channel-specific grounding (the input of a channel) must not have a potential difference of more than a command mode voltage of ± 6 V from the analog ground for the analog potential island on which all analog circuits are located (output with pins 10 and 20 of connectors X4 and X5). See for example the common mode voltage shown in "Wiring voltage inputs and ground reference (Page 36)". This is to be ensured with the correct input signal circuit connection to the analog ground. This can be at the encoder end, for example with non-floating voltage encoders, or at the AddFEM end, which is recommended for current encoders. See the details in the circuit examples described below. Note If there is no ground reference, analog measurement can still work because the common mode voltage is limited by naturally occurring transition resistance. With only highimpedance ground reference, however, the analog measurement can be sensitive to electromagnetic interference or electrostatic discharge. 32 Operating Instructions, 04/2018, A5E C-08

35 Connecting AddFEM 5.7 Interconnecting process signals Wire current inputs as singular and non-redundant or redundant Current inputs, singular and non-redundant 1 2 Ground reference at AddFEM Analog M connection pin 10/20 to cabinet ground not necessary Note If only current inputs are used, we recommend establishing the ground reference between the inputs and the analog ground at the AddFEM. Connecting the analog ground to the cabinet ground 2 is not necessary for the AddFEM in this case and is not recommended. If the current transducer (measuring transducer) requires a connection to the cabinet ground, the connection can be established there. Operating Instructions, 04/2018, A5E C-08 33

36 Connecting AddFEM 5.7 Interconnecting process signals Redundant current inputs 1 2 Connect electrical circuit to analog M of the two AddFEM An additional connection of M to the cabinet ground is not necessary. You can find more detailed information about the Zener diodes in "Selecting Zener diodes (Page 35)". Note If only current inputs are used, we recommend establishing the ground reference between the inputs and the analog ground at the AddFEM. Connecting the analog ground to the cabinet ground 2 is not necessary for the AddFEM in this case and is not recommended. If the current transducer (measuring transducer) requires a connection to the cabinet ground, the connection can be established there. 34 Operating Instructions, 04/2018, A5E C-08

37 Connecting AddFEM 5.7 Interconnecting process signals Selecting Zener diodes Zener diodes with higher voltage generally have a smaller leakage current and therefore ensure accuracy. A the voltage of the Z diodes increases, however, so too does the common mode voltage (voltage between input and M analog of the AddFEM 1 in the "Wire current inputs as singular and non-redundant or redundant (Page 33)") in the event of an error (AddFEM 2 is pulled - see same section). This reduces the accuracy of the AddFEM when the partner module is pulled by -0.05% per V. See "Analog inputs and outputs (Page 82)". The best results (low voltage and good insulation) can be achieved with series connection of 2 or 3 special diodes in the direction of flow instead of 2.7 V Z diodes for 20 ma inputs or 3.3 V Z diodes for 30 ma inputs. We recommend the use of diode ZPD1 (or BZX55C0V8) with 2 (~ 1.6 V) or 3 (~ 2.4 V) in series, as shown in the table below: 2 ZPD1 diodes in series for 0 to +20/24 ma inputs 3 ZPD1 diodes in series for 0 to +30/34 ma inputs 2 2 ZPD1 diodes, bidirectional in series for 0 to ± 20/24 ma inputs 2 3 ZPD1 diodes, bidirectional in series for 0 to ± 30/34 ma inputs Manufacturer: Diotec Semiconductor AG ( Operating Instructions, 04/2018, A5E C-08 35

38 Connecting AddFEM 5.7 Interconnecting process signals Wiring voltage inputs and ground reference Connector pin assignment If all encoders connected to the same AddFEM are potential-free, the ground connection for voltage inputs can, as for current inputs, be at the AddFEM as detailed in "Wire current inputs as singular and non-redundant or redundant (Page 33)". This is shown in the figure below. 1 2 Establish ground reference for each voltage channel at the AddFEM end Connecting M analog to the ground for voltage signals is not necessary and is not recommended 36 Operating Instructions, 04/2018, A5E C-08

39 Connecting AddFEM 5.7 Interconnecting process signals If voltage transducers already have an external reference to the ground line for voltage signals, the system should be as in the figure below. To securely limit the common mode voltage 2, M 1 analog of the AddFEM must be connected to the ground line to which the voltage transducers (measuring transducers) are also connected. 1 2 Establish ground reference for each voltage channel at the encoder end Common mode voltage < ± 6 V Operating Instructions, 04/2018, A5E C-08 37

40 Connecting AddFEM 5.7 Interconnecting process signals Using mixture of current and voltage inputs If you are using a mixed assignment of current and voltage transducers to the analog inputs, we recommend only establishing the ground reference for the current inputs at the AddFEM. The ground reference of the voltage-producing measuring transducers should only be implemented at the encoder end. Otherwise, the ground lines for the voltage signals would run together with the ground lines for the current signals at the AddFEM. If the currentproducing transmitters are not configured as floating, this leads to compensating currents between the 2 ground systems and to a loss of accuracy in the voltage signals as a result of a potential shift in the ground line for voltage signals. Note The central grounding point in the system must ensure that the ground reference for voltage signals is connected to the ground in one place for the current signals, so that the common mode voltage at the voltage inputs of the AddFEM is not exceeded. See figure below. 38 Operating Instructions, 04/2018, A5E C-08

41 Connecting AddFEM 5.7 Interconnecting process signals Interconnecting inputs and outputs with redundancy response Interconnecting redundant inputs and outputs All analog and digital outputs of an AddFEM can be connected in parallel to outputs of the same type at another AddFEM for the redundant control of actuators. The configuration is shown in the table below. The same applies to analog voltage inputs and digital inputs. Information on the redundant interconnection of the current inputs can be found in "Wire current inputs as singular and non-redundant or redundant (Page 33)". Note Redundant AddFEM require absolutely symmetrical assignment of I/O signals. With AddFEM PoCo Plus 6DL3100-8AC05 with an extended redundancy concept only, individual channels can be operated in non-redundant mode and wired differently in a redundant configuration.

42 Connecting AddFEM 5.7 Interconnecting process signals Redundancy response of the analog outputs The analog outputs of redundant AddFEM can only be enabled on the master AddFEM. Load distribution between the master and reserve module, for example of 50% to 60%, is only possible for control outputs with: AddFEM PoCo, 6DL3100-8AC02 AddFEM PoCo Plus, 6DL3100-8AC05 40 Operating Instructions, 04/2018, A5E C-08

43 Operating AddFEM Key switch The AddFEM comes in two versions with differences in the types of key switch and in the 4 switch positions. The table below shows the switch positions of the previous and of the new version. Previous version New version This document describes the previous version. It is the selected switch position RUN P, MRES, STOP and RUN that is important and not the turning position of the key switch. Operating Instructions, 04/2018, A5E C-08 41

44 Operating AddFEM 6.2 Operator controls and display elements 6.2 Operator controls and display elements Operator controls All operator controls and display elements are located on the front panel of the AddFEM above the protective cover. See "Design of the AddFEM (Page 10)". The AddFEM can be operated with a key switch and a toggle switch on the front panel. The individual switch positions are explained below. Normal operation the analog outputs are enabled In this position, you can remove the key to prevent unauthorized changes of operating mode. The outputs are disabled In AddFEM redundant mode, a master-reserve switchover is forced, i.e. the AddFEM becomes the "reserve" module. You can set the PROFIBUS DP addresses and reset the AddFEM. In this position, you can remove the key to prevent unauthorized changes of operating mode. Momentary action position of the key switch Required for setting the PROFIBUS DP addresses. Reserved for function expansions In this position, you cannot remove the key. LED Position 2 latching position: No function Position 1 latching position: Neutral position Position 0 spring-loaded momentary action position: The PROFIBUS DP addresses are displayed in binary code by the signal LEDs. The display is enabled for c. 3 s. There are 3 LED arrays above the key switch, each with 4 LEDs, for error displays and status displays. 42 Operating Instructions, 04/2018, A5E C-08

45 Setting the PROFIBUS DP address Configuring the AddFEM The AddFEM is configured over PROFIBUS DP according to the procedures defined in the PROFIBUS standard. The CD supplied with the AddFEM contains GSD files that can be edited using the standard PROFIBUS configuration tools, for example HW Config or COM- PROFIBUS. The configuration tool generates a master parameter data set, which is saved to the automation processor and is loaded to the AddFEM during the initialization phase. Please see the description of the individual configuration tools for more detailed information. You will find more information on using the GSD files in the "readme.pdf" on the AddFEM CD. 7.2 Setting the PROFIBUS DP address A unique address has to be assigned in order to address every single node on PROFIBUS DP. This PROFIBUS DP address can be set in a range of "1" to "125". You can set the PROFIBUS DP address of the AddFEM using the key switch and toggle switch, or in SIMATIC Manager. Both options are described below. In the case of a redundant PROFIBUS DP connection, it makes sense to assign the same address for both PROFIBUS DPs of an AddFEM however, the two addresses can also be set differently. An address set once remains set even after a voltage failure as it is saved in the read-only memory of the AddFEM. For the three to four AddFEM on each PROFIBUS DP line (typical configuration in turbine control systems), you should assign addresses in as low a range as possible, for example "2", "3", "4" or "5", to simplify the setup procedure.

50 Setting the PROFIBUS DP address 7.4 Setting the PROFIBUS DP address for bus B with the key switch and slide switch 7.4 Setting the PROFIBUS DP address for bus B with the key switch and slide switch The following section details the steps to be followed by maintenance and service personnel using the AddFEM operator controls (key switch and toggle switch) for setting the PROFIBUS DP address for bus B (connector X3B at the AddFEM). Note The procedure described below is largely the same as that for setting the PROFIBUS DP address for bus A. However, in step 2, the toggle switch must be pressed again in position 0 to set function mode 2, "Set DP address B".

53 Setting the PROFIBUS DP address 7.6 Setting the PROFIBUS DP address with SIMATIC Manager 7.6 Setting the PROFIBUS DP address with SIMATIC Manager As an alternative to the procedure detailed above with the toggle switch and key switch, the PROFIBUS DP address can also be set with a SIMATIC programming device. The SSA frame SSA: SET SLAVE ADDRESS, which contains the new PROFIBUS DP address, is sent to the AddFEM over the PROFIBUS DP. Once the frame has been received, the new address is automatically saved in the read-only memory of the AddFEM and is therefore permanently available. The setting must be made twice, once for PROFIBUS DP A and once for PROFIBUS DP B. Before the PROFIBUS DP address can be set, the programming device PG 740, PG 760, etc. must be connected to the AddFEM with an MPI cable. The MPI cable is connected to the AddFEM at PROFIBUS DP interface X3A or X3B. A new address can be assigned immediately after SIMATIC Manager startup and menu selection "Target system > Assign PROFIBUS address". The old address is also displayed.

55 How the AddFEM works Preprocessing functions with AddFEM 6DL3100-8AC The preprocessing function only applies to AddFEM 6DL3100-8AC. Certain automation functions, such as positioners for turbine control, can be run with AddFEM 6DL3100-8AC as preprocessing functions. This makes it possible to move timecritical functions requiring short cycle times from the higher level automation system to the AddFEM to reduce the time-critical task load for the higher-level automation system. These preprocessing functions are known as front-end functions. FE functions are provided as ready-to-use functions that are specifically configured by the user with additional parameters and so can be optimized for the process in question. The following FE functions can be ordered; the additional functions are detailed separately in the relevant directories on the AddFEM CD: 6DL3100-8AC02 AddFEM PoCo for high-speed control 6DL3100-8AC03 AddFEM SOE for rapid time stamping of digital input signals 6DL3100-8AC05 AddFEM PoCo Plus, expansion of AddFEM PoCo, in particular for the use of channelselective redundancy Note Other customer-specific individual solutions that have been developed for a limited group of customers only are not listed here; they are detailed separately. The range of FE functions can be expanded. If there are customer-specific applications that cannot be covered by the automation components available to date or only with extensive work, you have the option of commissioning a downloadable FE function. For the contact persons for additional customer-specific FE applications, please see "Industry Services and Industry Mall, Digital Factory" in the Preface.

56 How the AddFEM works 8.2 General functions 8.2 General functions Introduction Malfunctions or errors must be detected, localized and reported as quickly as possible. The AddFEM self-test is run in full after POWER ON (run up self test) and in sections during normal cyclic operation (cycle self test). See section "General technical specifications (Page 73)". Self-tests and self-monitoring The following components and functions are tested: RAM memory test RAM checksum test (calibration data and program code) FEPROM checksum test (calibration data and program code) Self-tests in cyclic operation Some error evaluation processes must be synchronized with the I/O cycle and are therefore part of the I/O cycle. Self-test in the I/O cycle: PROFIBUS functionality Data transfer between host and the AddFEM Data transfer between redundant AddFEM Runtime of cycles Power supply Channel fault of the process inputs or process outputs Co-processor monitoring by main processor Delayed shutdown In the case of brief failures of the host or a failure of communication via the PROFIBUS DP, the process outputs are not switched off until after a configurable tolerance time. The tolerance time can be set in a range of 10 ms to 3 s. The default setting is 0.5 s. See "Setting the PROFIBUS DP address (Page 43)". 54 Operating Instructions, 04/2018, A5E C-08

57 How the AddFEM works 8.3 How 2-channel speed monitoring with rotational direction detection works Signal filters for analog inputs The analog input signals can be digitally filtered. There are line filters for 50 Hz, 60 Hz, 16 2/3 Hz and 500 Hz. Filtering is set individually on a channel-selective basis for each analog input with the parameter assignment frame. The following settings are possible: No filtering The default is "off", i.e. there is no filtering. 50 Hz 60 Hz 16 2/3 Hz 500 Hz Note 500 Hz can only be set as of 6DL3100-8AC version How 2-channel speed monitoring with rotational direction detection works As of version 8 of 6DL3100-8AA or version 7 of 6DL3100-8AB/-8AC, channels 1 and 2 can be used for count frequency monitoring with rotational direction detection. A suitable 2- channel encoder needs to be connected to channels 1 and 2 for this purpose. The leading signal is connected to channel 1 and the lagging signal to channel 2. Channel 3 can also be used on a single-channel basis, i.e. without rotational direction detection, irrespective of the above setting. The signed frequency recorded on the 2 channels and is displayed on both channel 1 and channel 2 as follows: The frequency is calculated separately for each channel on the basis of the pulses from the connected encoder. The sign for the direction of rotation is determined by the phase offset of the two channels and is assigned to both channels. Operating Instructions, 04/2018, A5E C-08 55

58 How the AddFEM works 8.3 How 2-channel speed monitoring with rotational direction detection works Response to failure of one of the two encoders If one of the two signals fails, the speed of the failed channel is gradually reduced to 0 as for single-channel recording. See "General technical specifications (Page 73)". The sign is frozen in its state before the fault. This means that speed detection is still possible on one channel in the event of a fault. However, changes in the direction are no longer detected. A wire break can, for example, be detected by a parity check for the two channels. When conducting a parity check, however, remember that inaccuracies in the motion sensor (tooth edges) and acceleration processes, see "Operating modes (Page 57)", can lead to differences between the two channels. In the light of the large number of possible applications, channel-specific wire break detection must therefore implemented in the host system on a plant-specific basis rather than in the module. Updates and possible speed difference between the two channels Internal module frequency calculation is always linked to a signal change for measurement of the period, and therefore occurs at different times for the 2 phase-shifted encoders. Speed changes therefore lead to small deviations between the displays of channel 1 and channel 2, as each channel in turn has a more recent value than the other. Recency and accuracy and can therefore be increased, in particular for slow speeds, by averaging the values from the two channels. The speed difference between the two channels resulting from acceleration, which must at least be considered if the two channels are being monitored, is of the following order: Applies to frequencies 125 Hz Δf = a 2 ms Δf = Speed difference, a = Acceleration, f = Frequency Applies to frequencies > 125 Hz Note This is a simplified formula for encoders with rotational direction detection, in which both channels operate with phase shifting of Operating Instructions, 04/2018, A5E C-08

59 How the AddFEM works 8.4 Operating modes 8.4 Operating modes System configurations The AddFEM can be configured as singular or redundant with one or two PROFIBUS DP channels in line with the application. There are four system configurations. The configuration is set, see also "Configurable parameters". There is no automatic detection or adaption by the AddFEM. The operating mode on the AddFEM is set using the PROFIBUS DP parameter frame in line with the required system configuration. Note With the basic setting for AddFEM redundancy modes, the configuration does not need to be changed if 6DL3100-8AA is replaced with 6DL3100-8AB/-8AC. Setting the operating mode If you are using SIMATIC S7, the PROFIBUS DP parameters can be set using the HW Config in SIMATIC Manager. If you are using another system, the relevant settings are made with the COM-PROFIBUS software package. Operating mode Host AddFEM PROFIBUS 0 Single-channel Single-channel 1 PROFIBUS DP line 1 Redundant Single-channel 2 PROFIBUS DP lines 2 Single-channel Redundant 1 PROFIBUS DP line 3 Redundant Redundant 2 PROFIBUS DP lines Note After POWER ON, the AddFEM remains in the STARTUP state (RUN LED flashing) until the operating mode specified in the parameter assignment is established.

62 How the AddFEM works 8.5 Redundant functions with AddFEM 8.5 Redundant functions with AddFEM Improving availability with redundancy Redundancy in this context means implementing a 1 out of 2 structure. Availability is increased by using two identical components in parallel. If one component fails following a fault, the second component takes over smoothly. Comprehensive redundancy mechanisms and integrated diagnostics functions in AddFEM ensure automatic error detection and switchover without any manual operations required. Master AddFEM and reserve AddFEM The terms "Master" and "Reserve" are used below to refer to the two AddFEM. The "Reserve" AddFEM operates at the same time as the "Master" AddFEM and not only in the event of a fault. The process outputs of the "Reserve" AddFEM are, however, passive: no signals are output. Features of redundant AddFEM If one AddFEM fails, the system automatically switches to the redundant unit ("1 out of 2" structure). Seamless change of "master" function with redundancy interface fiber-optic link. The change in "master" role initiated by the AddFEM after error detection, in other words switching off the outputs of what has been the master and switching on the outputs of what has been the reserve, is more or less seamless. Tolerance-specific switchover gap see "General technical specifications (Page 73)". FO link Serial bidirectional "redundancy" communication over fiber-optic cables is in place between redundant AddFEM, allowing error status, redundancy status and update data to be exchanged. Master/reserve specification If there is a balanced error rating in the redundant AddFEM, specification is by the AP. This soft preset can also be used to implement a cyclic M/R change (24 hours), for example. Forced reserve selection If there is no redundant fiber-optic link, or the link is faulty, master/reserve assignment is set by the AP. 60 Operating Instructions, 04/2018, A5E C-08

63 How the AddFEM works 8.5 Redundant functions with AddFEM Master/reserve switchover The master module is the active controller until it detects an error in itself, in which case it transfer the master function to the reserve module. Note AddFEM PoCo Plus 6DL3100-8AC05 has supplementary channel-selective redundancy mechanisms (see AddFEM PoCo Plus manual). The handover of the master role is always performed through error rating. The error rating of a module is derived from the weighted sum of all individual errors. Errors that affect the basic function of the module, for example memory errors, have a higher rating, whereas channel errors are handled with the lowest priority for error rating. Channel errors that are included in the error rating are taken from monitoring for the 12 analog measurements, the 8 analog outputs and the 16 digital outputs (which can also be used as digital inputs). Each channel is weighted with the same factor to determine the error rating. 1. For analog measurement, the signal range is monitored. With 4 to 20 ma signals, a channel error is set upon a high or low violation of the range. Measuring range Signal high limit Signal low limit 4 to 20 ma 0 to 20 ma ± 20 ma ± 30 ma 0 to 10 V ± 10 V ma ma ma ma V V ma ma ma ma V V 2. For analog output, the output signal required and the output signal read back are compared to check whether they correspond. A short circuit to ground or wire break cannot be detected if the output is set to For digital output, the signal is read back and monitored for a short circuit to ground when a level of 1 is output. Master/reserve switchover without fiber-optic cable The automation processor assigns master/reserve mode if the fiber optic link fails. The current error rating of the modules is key to the assignment. Process inputs and outputs Redundant AddFEM require absolutely symmetrical assignment of I/O signals. "AddFEM PoCo Plus" is an exception see the relevant description. Operating Instructions, 04/2018, A5E C-08 61

64 How the AddFEM works 8.5 Redundant functions with AddFEM Redundant nodes Redundant nodes represent the fail-safety of systems with redundant components. A redundant node can be considered as independent when the failure of one component does not result in reliability constraints in other nodes or in the overall system. With a 1-out-of-2 structure, one component of the redundant node can fail without impairing the operability of the overall system. The two automation processors AP A and AP B run the same application software synchronously and cyclically, for example a turbine control function. One system (AP A or AP B) is the master and actively controls the outputs. In the event of errors in the master system, master control is automatically and smoothly transferred to the reserve system. The redundancy status and additional update information is exchanged between AddFEM A and AddFEM B over the redundant link. 62 Operating Instructions, 04/2018, A5E C-08

65 How the AddFEM works 8.6 Redundant PROFIBUS DP I/O 8.6 Redundant PROFIBUS DP I/O The PROFIBUS DP channels are equivalent. The AddFEM changes channels if it detects a DP error or sign-of-life change/error, or receives a GCCL frame. A switchover of PROFIBUS DP channels by the AP is always initiated by the sign-of-life. For switching DP channels, version 6DL3100-8AC supports the PrmCommand in accordance with PROFIBUS Guideline and outputs the redundancy status as diagnostics. The AddFEM and AP are linked by a redundant PROFIBUS DP A and PROFIBUS DP B connection. Each AddFEM has two PROFIBUS DP I/O. The two buses operate in parallel. The input data (input) is always transferred in parallel to both automation processors. The AddFEM outputs can only "follow" the control signals of one of the two automation processors, AP A or AP B, i.e. the AddFEM outputs either the output data of AP A or the output data of AP B. A master/reserve switchover is therefore also required for the outputs for the AddFEM. The output information of the passive AP is analyzed for monitoring purposes and then discarded. The output-specific switchover is based on various criteria. The system always switches to the operable interface in response to a coupling failure. In the event of total failure, i.e. if neither interface receives any frames, safety-oriented zero signals are output. Note In addition to the AddFEM switching bus channels, the automation processor AP can also actively initiate a switchover. The AP can actively specify which interface, DP A or DP B, is to be used.

INIT Initialization phase The AddFEM executes the following functions in the initialization phase: Hardware function settings Self-test Wait c. 4 seconds until PROFIBUS DP frames are received STARTUP The address currently set for PROFIBUS DP A (socket X3A) is displayed in binary format on the 16 signal LEDs for the digital inputs. If any fatal errors occur, the AddFEM is reset and assumes the "RESET" state Startup phase The AddFEM remains in the startup phase if it does not receive any PROFIBUS DP frames. Possible reasons: The PROFIBUS DP master is not yet ready The PROFIBUS DP connector is not plugged in, is defective, or has not been terminated. 64 Operating Instructions, 04/2018, A5E C-08

67 Functions of the AddFEM 9.1 Operating states LOAD PARAMETER Parameter assignment If the parameters required for the operation of the relevant AddFEM version are not transferred by the HOST (PROFIBUS DP master), the AddFEM will remain in this phase. Possible reason: Incorrect or no driver block (T3000 HW proxy or PCS 7 driver) With PoCo Plus as of FEF version 03, the module remains in this state if parameter values are outside the permissible range (TN, SETO_TIME1 or YPI_TIME2 > 262 s) CONNECT PASSIVE Connecting to redundancy partner - reserve Data is synchronized with the redundant partner, i.e. with the redundant AddFEM for this module, over the redundant fiber optic link. The module then assumes the RUN PASSIVE state. CONNECT ACTIVE Connecting to redundancy partner - master Data is synchronized with the redundant partner, i.e. with the redundant AddFEM for this module, over the redundant fiber optic link. The module then assumes the RUN ACTIVE state. RUN PASSIVE RUN state - reserve The module is the reserve and receives update data from the master module over the redundant fiber optic link. The outputs are disabled, i.e. no analog signals are output. RUN ACTIVE RUN state active The module is the master and sends update data to the reserve module over the redundant fiber optic link. Operating Instructions, 04/2018, A5E C-08 65

68 Functions of the AddFEM 9.1 Operating states STOP STOP state Can only be set using the key switch. The outputs are disabled, i.e. no analog signals are output. In the STOP state, you can set the bus address and reset the AddFEM using the control switches. INIT INIT state No complete and therefore executable firmware found. The module remains in the INIT state. All red error LEDs flash. The error may have been caused by a defective component or an interrupted firmware update download.

The LED is controlled statically: If master monitoring has been enabled. The LED flashes in the event of configuration errors: If the parameter assignment frame received contains invalid parameter values If the parameter values received do not correspond to the redundancy partner parameter assignment in redundant configuration RED Redundancy error Only relevant with redundant AddFEM configuration. The LED comes on: If the fiber-optic link between the two redundant AddFEM fails. The LED flashes: If the parameter assignment of the redundant AddFEM is not consistent. STOP Offline (stop) AddFEM in the STOP state. The outputs are disabled. A master/reserve switchover is forced if there is a redundant module, i.e. the module is set to "forced reserve." In this state, you can also run the procedures for setting PROFIBUS DP addresses and resetting the AddFEM. DISO Output disable Outputs are disabled for commissioning or maintenance work. The AddFEM is in STOP, or in the passive reserve state (with module redundancy). 68 Operating Instructions, 04/2018, A5E C-08

72 Functions of the AddFEM 9.2 Error and status LED display functions Note If you cannot find the error state displayed in the table above, check the table in "Operating states (Page 64)" for the operating state displays to see whether the AddFEM has remained in the module startup phase due to another error. Note EXTF error display with redundant AddFEM Faults in the process outputs signals (analog outputs; digital outputs) are displayed with the EXTF LED. If a signal fault occurs at the master module, the reserve module assumes the master function. The error display EXTF, for example following a wire break at an analog output, remains saved on the reserve module, however, and cannot be reset, as the reserve module is no longer active and therefore cannot check the line state. Procedure with EXTF: If the display has been caused by an "Analog out" process signal error (e.g. wire break at an analog output) or "Digital out" process signal error (e.g. short circuit to ground), check "Resetting errors with module redundancy (Page 102)". 70 Operating Instructions, 04/2018, A5E C-08
