11 Promag 53 PROFIBUS-DP/-PA 3 Installation 3 Installation 3.1 Incoming acceptance, transport and storage Incoming acceptance Check the packaging and the contents for damage. Check the shipment, make sure nothing is missing and that the scope of supply matches your order Transport The following instructions apply to unpacking and to transporting the device to its final location: Transport the devices in the containers in which they are delivered. Do not remove the protective plates or caps on the process connections until the device is ready to install. This is particularly important in the case of sensors with Teflon linings. Special notes on flanged devices Caution: The wooden covers mounted on the flanges before the device leaves the factory protect the linings on the flanges during storage and transportation. Do not remove these covers until immediately before the device is installed in the pipe. Do not lift flanged devices by the transmitter housing, or the connection housing in the case of the remote version. Transporting flanged devices (DN 300): Use webbing slings slung round the two process connections (Fig. 3). Do not use chains, as they could damage the housing. Warning: Risk of injury if the measuring device slips. The center of gravity of the assembled measuring device might be higher than the points around which the slings are slung. At all times, therefore, make sure that the device does not unexpectedly turn around its axis or slip. F06-xxxxxxxx xx-000 Fig. 3: Transporting transmitters with DN 300 Endress+Hauser 11

12 3 Installation Promag 53 PROFIBUS-DP/-PA Transporting flanged devices (DN 350): Use only the metal eyes on the flanges for transporting the device, lifting it and positioning the sensor in the piping. Caution: Do not attempt to lift the sensor with the tines of a fork-lift truck beneath the metal casing. This would buckle the casing and damage the internal magnetic coils. F06-5xFxxxxx-22-xx-xx-xx-001 Fig. 4: Transporting sensors with DN Storage Note the following points: Pack the measuring device in such a way as to protect it reliably against impact for storage (and transportation). The original packaging provides optimum protection. The permissible storage temperature is C (preferably +20 C). Do not remove the protective plates or caps on the process connections until the device is ready to install. This is particularly important in the case of sensors with Teflon linings. 12 Endress+Hauser

13 Promag 53 PROFIBUS-DP/-PA 3 Installation 3.2 Installation conditions Dimensions Dimensions and the fitting lengths of the transmitter and sensor are on Page 145 ff Mounting location Correct measuring is possible only if the pipe is full. Avoid the following locations: Highest point of a pipeline. Risk of air accumulating. Directly upstream of a free pipe outlet in a vertical pipe. Fig. 5: Mounting location Installation of pumps Do not install the sensor on the intake side of a pump. This precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring tube. Information on the lining's resistance to partial vacuum can be found on Page 142. It might be necessary to install pulse dampers in systems incorporating reciprocating, diaphragm or peristaltic pumps. Information on the measuring system's resistance to vibration and shock can be found on Page 133. F06-5xxxxxxx xx-001 F06-5xxxxxxx xx-000 Fig. 6: Installation of pumps Endress+Hauser 13

14 3 Installation Promag 53 PROFIBUS-DP/-PA Partially filled pipes Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe Detection function (see Page 106) offers additional protection by detecting empty or partially filled pipes. Caution: Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable to install a cleaning valve. Fig. 7: Installation in partially filled pipe Down pipes Install a siphon or a vent valve downstream of the sensor in down pipes longer than 5 meters. This precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring tube. These measures also prevent the system losing prime, which could cause air inclusions. Information on the lining's resistance to partial vacuum can be found on Page 142.

15 Promag 53 PROFIBUS-DP/-PA 3 Installation Orientation An optimum orientation position helps avoid gas and air accumulations and deposits in the measuring tube. Promag, nevertheless, supplies a range of functions and accessories for correct measuring of problematic fluids: Electrode Cleaning Circuit (ECC) for applications with accretive fluids, e.g. electrically conductive deposits Description of Device Functions manual. Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes, e.g. in the case of degassing fluids or varying process pressures (see Page 106) Exchangeable measuring electrodes for abrasive fluids (see Page 128) Vertical orientation This is the ideal orientation for self-emptying piping systems and for use in conjunction with Empty Pipe Detection. Fig. 9: Vertical orientation Horizontal orientation The measuring-electrode plane should be horizontal. This prevents brief insulation of the two electrodes by entrained air bubbles. Caution: Empty Pipe Detection functions correctly with the measuring device installed horizontally only when the transmitter housing is facing upward (Fig. 10). Otherwise there is no guarantee that Empty Pipe Detection will respond if the measuring tube is only partially filled or empty. F06-5xxxxxxx xx-xx-000 F06-5xxxxxxx xx-004 Fig. 10: Horizontal orientation 1 EPD electrode for the detection of empty pipes (not with Promag H, DN 2...8) 2 Measurement electrodes for the signal acquisition 3 Reference electrode for the potential equalisation (not with Promag H) Endress+Hauser 15

16 3 Installation Promag 53 PROFIBUS-DP/-PA Inlet and outlet runs If possible, install the sensor well clear of fittings such as valves, T-pieces, elbows, etc. Compliance with the following requirements for the inlet and outlet runs is necessary in order to ensure measuring accuracy: Inlet run 5 x DN Outlet run 2 x DN Fig. 11: Inlet and outlet runs Vibrations Secure the piping and the sensor if vibration is severe. Caution: It is advisable to install sensor and transmitter separately if vibration is excessively severe. Information on resistance to vibration and shock can be found on Page 133. F06-5xxxxxxx xx-006 F06-5xxxxxxx xx-005 Fig. 12: Measures to prevent vibration of the measuring device 16 Endress+Hauser

17 Promag 53 PROFIBUS-DP/-PA 3 Installation Foundations, supports If the nominal diameter is DN 350, mount the transmitter on a foundation of adequate load-bearing strength. Caution: Risk of damage. Do not support the weight of the sensor on the metal casing: the casing would buckle and damage the internal magnetic coils. F06-5xFxxxxx xx-xx-000 Fig. 13: Correct support for large nominal diameters (DN 350) Endress+Hauser 17

18 3 Installation Promag 53 PROFIBUS-DP/-PA Adapters Suitable adapters to (E) DIN EN 545 (double-flange reducers) can be used to install the sensor in larger-diameter pipes. The resultant increase in the rate of flow improves measuring accuracy with very slow-moving fluids. The nomogram shown here can be used to calculate the pressure loss caused by crosssection reduction: Note: The nomogram applies to fluids of viscosity similar to water. 1. Calculate the ratio of the diameters d/d. 2. From the nomogram read off the pressure loss as a function of flow velocity (downstream from the reduction) and the d/d ratio. F06-5xxxxxxx xx-xx-000 Fig. 14: Pressure loss due to adapters Nominal diameter and flow rate The diameter of the pipe and the flow rate determine the nominal diameter of the sensor. The optimum velocity of flow is m/s. The velocity of flow (v), moreover, has to be matched to the physical properties of the fluid: v < 2 m/s: for abrasive fluids such as potter's clay, lime milk, ore slurry, etc. v > 2 m/s: for fluids producing build-up such as wastewater sludge, etc. Note: Flow velocity can be increased, if necessary, by reducing the nominal diameter of the sensor (see Page 18). 18 Endress+Hauser

37 Promag 53 PROFIBUS-DP/-PA 3 Installation Installing the Promag H sensor The Promag H is supplied to order, with or without pre-installed process connections. Pre-installed process connections are secured to the sensor with hex-head threaded fasteners. Caution: If you intend to use your own process connections, make up the process adapters as specified on Page 160 ff.. The sensor might require support or additional attachments, depending on the application and the length of the piping run.

Firmly tighten the threaded fasteners. The process connection forms a metallic connection with the sensor, which ensures a defined compression of the seal. Caution: The seals must be replaced periodically, depending on the application, particularly in the case of gasket seals (aseptic version). The period between changes depends on the frequency of cleaning cycles, the cleaning temperature and the fluid temperature. Replacement seals can be ordered as accessories Page 111.

38 3 Installation Promag 53 PROFIBUS-DP/-PA Usage and assembly of ground rings (DN ) In case the process connections are made of plastic (e.g. flanges or adhesive fittings), the potential between the sensor and the fluid must be equalised using additional ground rings. If the ground rings are not installed this can affect the accuracy of the measurements or cause the destruction of the sensor through the electrochemical erosion of the electrodes. Caution: At the factory, plastic rings will be inserted in the process connections instead of the ground rings. These are only intended as placeholders and do not provide potential equalisation. Before installing the ground rings, please observe the following points: ground rings can be ordered separately from E+H as accessories (see Page 111). When placing the order, make certain the included o-ring seals are of the same material as the seals that are used for the process connections. When placing the order, make certain that the grounding ring is compatible with the material used for the electrodes. Otherwise, there is a risk that the electrodes may be destroyed by electrochemical corrosion! Information about the materials can be found on page 137. The dimensions of the ground rings can be found on page 167. ground rings, including the seals, are mounted within the process connections. Therefore, the fitting length is not affected. For plastic flange connections, ground disks, which are mounted between the flanges, can be used instead of ground rings. 1. Loosen the four hexagonal headed bolts (1) and remove the process connection from the sensor (5). 2. Remove the plastic disk (3), including the two o-ring seals. 3. Place the new seal (2) in the groove of the process connection. 4. Place the metal ground ring (3) on the process connection. 5. Now place the second seal (4) in the groove of the ground ring. 6. Finally, mount the process connection on the sensor again F06-xxHxxxxx-17-xx-xx-xx-001 Fig. 22: Installing ground rings with a Promag H (DN ) 1 Hexagonal headed bolts (process connection) 2 O-ring seal for the process connection 3 Plastic disk (placeholder) or ground ring 4 O-ring seal for the ground ring 5 Sensor Promag H 38 Endress+Hauser

39 Promag 53 PROFIBUS-DP/-PA 3 Installation Welding the sensor into the piping (weld nipple) Caution: Risk of destroying the measuring electronics. Make sure that the welding machine is not grounded via the sensor or the transmitter. 1. Tack-weld the Promag H sensor into the pipe. A suitable welding jig can be ordered separately from E+H as an accessory (see Page 111). 2. Remove the threaded fasteners from the process-connection flange. Remove the sensor complete with seal from the pipe. 3. Weld the process connection into the pipe. 4. Reinstall the sensor in the pipe. Make sure that everything is clean and that the seal is correctly seated. Note: If thin-walled foodstuffs pipes are not welded correctly, the heat could damage the installed seal. It is therefore advisable to remove the sensor and the seal prior to welding. The pipe has to be spread approximately 8 mm to permit disassembly.

With PROFIBUS-RS 485 Cable Type A, this value is: Transmission Rate [kbit/s] Cable length [m] A maximum of 32 stations are permitted per segment. Each segment is terminated at both ends with a terminating resistor. The bus length or number of users can be increased by installing a repeater. The first and last segments can support a max. of 31 devices. The segments between repeaters can support a max. of 30 stations. The maximum distance achievable between two bus users is calculated as: (NUM_REP + 1) x segment length NUM_REP = maximum number of repeaters, which can be placed in series, dependent on the respective repeater. Example: According to the manufacturer's information, a maximum of 9 repeaters may be placed in series on a standard line. The maximum distance between two bus users at a transmission rate of 1.5 MBit/s is thus: (9 + 1) x 200 m = 2000 m Endress+Hauser 45

46 4 Wiring Promag 53 PROFIBUS-DP/-PA Stubs (PROFIBUS -DP) Note the following points: Total combined length of all stubs < 6.6 m (at a max. of 1.5 MBit/s) At transmission rates >1.5 MBit/s, stubs should not be used. The line between the cable connector and the bus driver in the field device is called a stub. Our experience with the systems, indicates that you should be quite careful with the length of the stubs when planning your project. Therefore, we recommend that you do not attempt to utilise the full theoretical maximum total combined length of 6.6 m for all stubs at 1.5 MBit/s. The order of the respective field devices makes more of a difference in this case. We recommend that at transmission rates >1.5 MBit/s you avoid using stubs. If you must use stubs, do not install terminating resistors on them. Shielding and grounding (PROFIBUS-DP/-PA) When planning the shielding and grounding for a field bus system, there are three important points to consider: Electromagnetic compatibility (EMC) Explosion protection Safety of the personnel To ensure the optimum electromagnetic compatibility of systems, it is important that the system components and above all the cables, which connect the components, are shielded and that no portion of the system is unshielded. Ideally, the cable shields will be connected to the field devices' housings, which are usually metal. Since these housings are generally connected to the protective ground conductor, the shield of the bus cable will thus be grounded many times. This approach, which provides the best electromagnetic compatibility and personnel safety, can be used without restriction in plants with good potential equalisation. In the case of plants without potential equalisation, a mains frequency (50 Hz) equalising current can flow between two grounding points, which in unfavorable cases, e.g. when it exceeds the permissible shield current, may destroy the cable. To suppress the low frequency equalising currents on systems lacking potential equalisation, it is therefore advisable to connect the cable shield directly to the building (or protective ground conductor) at only one end and to use capacitive coupling to connect it to all other grounding points. 46 Endress+Hauser

47 O N O N O Promag 53 PROFIBUS-DP/-PA 4 Wiring Setting the terminators Since mismatches in the impedance result in signal reflections on the line and can thus lead to communication errors, it is important to terminate the lines properly. Warning: Risk of electric shock. Exposed components carry dangerous voltages. Make sure that the power supply is switched off before you remove the cover of the electronics compartment. The terminator switches are located on the I/O board (see Fig. 29). For baud rates of up to 1.5 MBaud, terminate the last transmitter on the bus by setting the terminator switch SW 1 to: ON ON ON ON. If the device is to be operated at over 1.5 Mbaud, you can tap the supply voltage for an external terminator from terminals 24 (GND) and 25 (+5 V) (see Fig. 33). If the device is to be operated at a baud rate >1.5 Mbaud, an external terminator is necessary, e.g. with a 9-pin Sub D cable connector combination, with an integrated series inductance to compensate for the station's capacitive load and minimise the resulting line reflections.

48 4 Wiring Promag 53 PROFIBUS-DP/-PA PROFIBUS-PA: Cable specifications Cable type Twin-core cable is required for connecting the device to the fieldbus. By analogy with IEC protocol four different cable types (A, B, C, D) can be used with PROFIBUS protocol, only two of which (cable types A and B) are shielded. Cable types A or B are particularly preferable for new installations. Only these types have cable shielding that guarantees adequate protection from electromagnetic interference and thus the most reliable data transfer. On multi-pair cables (Type B), it is permissible to operate multiple fieldbuses (with the same degree of protection) on one cable. No other circuits are permissible in the same cable. Practical experience has shown that cable types C and D should not be used due to the lack of shielding, since the freedom from interference generally does not meet the requirements described in the standard. The electrical data of the fieldbus cable has not been specified but determines important characteristics of the design of the fieldbus, such as distances bridged, number of participants, electromagnetic compatibility, etc. Cable type A Cable type B Cable structure twisted pair, shielded one or more twisted pairs, fully shielded Wire size 0.8 mm 2 (AWG 18) 0.32 mm 2 (AWG 22) Loop resistance (DC) 44 Ω/km 112 Ω/km Impedance at khz 100 Ω ± 20% 100 Ω ± 30% Attenuation at 39 khz 3 db/km 5 db/km Capacitive asymmetry 2 nf/km 2 nf/km Envelope delay distortion (7.9 through 39 khz) 1.7 µs/km * Shield coverage 90% * Max. cable length (inc. spurs >1 m) 1900 m 1200 m * not specified Suitable fieldbus cables from various manufacturers for the non-hazardous area are listed below: Siemens: 6XV BH10 Belden: 3076F Kerpen: CeL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL 48 Endress+Hauser

49 Promag 53 PROFIBUS-DP/-PA 4 Wiring Maximum overall cable length The maximum network expansion depends on the type of ignition protection and the cable specifications. The overall cable length is made up of the length of the main cable and the length of all spurs (>1 m). Note the following points: The maximum permissible overall cable length depends on the cable type used. Type A Type B 1900 m 1200 m If repeaters are used the maximum permissible cable length is doubled. A maximum of four repeaters are permitted between station and master. Maximum spur length The line between distribution box and field device is described as a spur. In the case of non ex-rated applications the max. length of a spur depends on the number of spurs (>1 m): Number of spurs Max. length per spur 120 m 90 m 60 m 30 m 1 m Number of field devices In systems that meet FISCO in the EEx ia type of protection, the line length is limited a max. of 1000 m. A maximum of 32 stations per segment in non-explosive areas or a maximum of 10 stations in an Ex-area (EEx ia IIC) are possible. The actual number of stations must be determined during the project planning. Bus termination The start and end of each fieldbus segment are always to be terminated with a bus terminator. With various junction boxes (not ex-rated) the bus termination can be activated via a switch. If this is not the case a separate bus terminator must be installed. Note the following points in addition: In the case of a branched bus segment the device furthest from the segment connector represents the end of the bus. If the fieldbus is extended with a repeater then the extension must also be terminated at both ends.

Do not install or wire the device while it is connected to the power supply. Failure to comply with this precaution can result in irreparable damage to the electronics. Risk of electric shock. Connect the protective conductor to the ground terminal on the housing before the power supply is applied (not necessary if the power supply is galvanically isolated). Compare the specifications on the nameplate with the local voltage supply and frequency. The national regulations governing the installation of electrical equipment also apply. Procedure (Fig. 33, Fig. 34): 1. Remove the cover of the connection compartment (f) from the transmitter housing. 2. Feed the power-supply cable (a) and PROFIBUS cable (b) through the appropriate cable entries. Note: The Promag 53 can also be supplied with the option of a ready-mounted fieldbus connector. More information on this can be found on Page Connecting the cables: Wiring diagram (aluminum and stainless steel housings) Fig. 33 Wiring diagram (wall-mount housing) Fig. 34 Caution: The PROFIBUS cable can be damaged! If the shielding of the cable is grounded at more than one point in plants without additional potential equalisation, mains frequency equalisation currents can occur that damage the cable or the shielding. In such cases the shielding of the cable is to be grounded on only one side, i.e. it must not be connected to the ground terminal of the housing. The shield that is not connected should be insulated! We recommend that the PROFIBUS not be looped using conventional cable glands. If you later replace even just one measuring device, the bus communication for the entire bus will have to be interrupted. Note: The terminals for the PROFIBUS-PA connection (26/27) have an integral polarity protection. This ensures correct signal transmission via the fieldbus even if lines are confused.

56 4 Wiring Promag 53 PROFIBUS-DP/-PA Fieldbus connector Note: This connector can only be used for a PROFIBUS-PA device. The connection technology of PROFIBUS-PA allows measuring devices to be connected to the fieldbus via uniform mechanical connections such as T-boxes, junction boxes, etc. This connection technology using prefabricated distribution modules and plug-in connectors offers substantial advantages over conventional wiring: Field devices can be removed, replaced or added at any time during normal operation. The communications will not be interrupted. This simplifies installation and maintenance significantly. Existing cable infrastructures can be used and expanded instantly, e.g. when constructing new star distributors using 4-channel or 8-channel junction boxes. The Promag 53 can therefore be supplied with a ready-mounted fieldbus connector. Fieldbus connectors for retrofitting can be ordered from E+H as a spare part (see Page 111).

58 4 Wiring Promag 53 PROFIBUS-DP/-PA 4.4 Potential equalisation Standard case Proper measurement is only ensured when the fluid and sensor are at the same electrical potential. The majority of Promag sensors have, as part of their standard configuration, a built-in reference electrode, which ensures the required potential equalisation. As a rule, this is sufficient to eliminate the need for ground disks or other measures. Promag W: Reference electrode is standard Promag P: Reference electrode is optional, depending on material Promag H: No reference electrode. The metallic process connection provides a permanent electrical connection to the fluid. If the process connections are made of a synthetic material, ground disks have to be used to ensure that potential is equalised (see Page 38). Ground rings are optional accessories, which must be ordered separately Page 111. Note: When installed in metal pipes, we recommend that the transmitter housing's ground terminal be connected to the pipe. F06-5xxxxxxx-04-xx-xx-xx-002 Fig. 36: Potential equalisation by means of the transmitter's ground terminal Caution: If the sensor does not have a reference electrode or metallic process connections, the potential equalisation must be established in the manner described in the following special cases. These special measures are in particular necessary when the usual grounding is not ensured or when it is likely that there will be an excessive equalisation current. 58 Endress+Hauser

59 Promag 53 PROFIBUS-DP/-PA 4 Wiring Special cases Equalising currents in metallic, ungrounded pipes To prevent disturbances to the measurement, we recommend that both sensor flanges be connected with a grounding cable to the adjacent pipe flange and to ground.

Note: The grounding cable for flange-to-flange connections can be ordered separately as an accessory from E+H Page 111.

60 4 Wiring Promag 53 PROFIBUS-DP/-PA Plastic pipes or pipes lined with insulating material Normally the potential equalisation is accomplished via the reference electrodes in the measuring tube. However, it is still possible that in some cases due to a plant's grounding design that a large equalisation current will flow over the reference electrodes. This can cause the destruction of the sensor, e.g. through the electrochemical erosion of the electrodes. In such cases, e.g. with fiberglass or PVC pipes, we recommend that you use ground disks to improve the potential equalisation (Fig. 38). Mounting of ground disks Page 26, 32. Caution: Risk of damage by electrochemical corrosion. Note the electrochemical series of metals, if the ground disks and measuring electrodes are made of different materials. Fig. 38: Potential equalisation / ground disks with plastic pipes or lined pipes Lined pipes (cathodic protection) In such cases, the sensor should be installed in the pipes in a potential-free manner: When installing the measuring device, make sure that there is an electrical connection between the two piping runs (copper wire, 6 mm 2 ). Make sure that the installation materials do not establish a conductive connection to the measuring device and that the installation materials withstand the tightening torques applied when the threaded fasteners are tightened. Also comply with the regulations applicable to potential-free installation.

Compliance with the following points is mandatory following installation in the field or servicing, in order to ensure that IP 67 protection is maintained: The housing seals must be clean and undamaged when inserted into their grooves. The seals must be dried, cleaned or replaced if necessary. All threaded fasteners and screw covers must be firmly tightened. The cables used for connection must be of the specified outside diameter (see Page 132). Firmly tighten the cable entries (Fig. 40). The cables must loop down before they enter the cable entries ( water trap, Fig. 40). This arrangement prevents moisture penetrating the entry. Always install the measuring device in such a way that the cable entries do not point up. Remove all unused cable entries and insert plugs instead. Do not remove the grommet from the cable entry. F06-xxxxxxxx-04-xx-xx-xx-005 Fig. 40: Installation instructions, cable entries Caution: Do not loosen the threaded fasteners of the Promag sensor housing, as otherwise the degree of protection guaranteed by Endress+Hauser no longer applies. Note: The Promag W and Promag P sensors can be supplied with IP 68 rating (permanent immersion in water to a depth of 3 meters). In this case the transmitter must be installed remote from the sensor.

The function matrix, therefore, comprises a multiplicity of additional functions which, for the sake of clarity, are arranged on a number of menu levels (blocks, groups, and function groups). Comply with the following instructions when configuring functions: You select functions as described on Page 67. Each cell in the function matrix is identified by a numerical or letter code on the display. You can switch off certain functions (OFF). If you do so, related functions in other function groups will no longer be displayed. Certain functions prompt you to confirm your data entries. Press to select SURE [ YES ] and then press again to confirm. This saves your setting or starts a function, as applicable. Return to the HOME position is automatic if no key is pressed for 5 minutes. Programming mode is disabled automatically if you do not press a key within 60 seconds following automatic return to the HOME position. Note: The transmitter continues to measure while data entry is in progress, i.e. the current measured values are output via the signal outputs in the normal way. If the power supply fails, all preset and parameterised values remain safely stored in the EEPROM. Caution: All of the functions are described in detail, including the function matrix itself, in the Description of Device Functions manual, which is a separate part of this Operating Instruction! Enabling the programming mode The function matrix can be disabled. Disabling the function matrix rules out the possibility of inadvertent changes to device functions, numerical values or factory settings. You must first enter a numerical code (factory setting = 53) before you can change the settings. If you use a code number of your choice, you exclude the possibility of unauthorised persons accessing data ( see the Description of Device Functions manual). Comply with the following instructions when entering codes: If programming is disabled and the keys are pressed in any function, a prompt for the code will appear automatically on the display. If 0 is entered as the customer's code, programming is always enabled. The E+H service organisation can be of assistance if you mislay your personal code. Caution: Changing certain parameters such as all sensor characteristics, for example, influences numerous functions of the entire measuring system, particularly measuring accuracy. There is no need to change these parameters under normal circumstances and consequently, they are protected by a special code known only to the E+H service organisation. Please contact Endress+Hauser if you have any questions. 68 Endress+Hauser

69 y Promag 53 PROFIBUS-DP/-PA 5 Operation Disabling the programming mode Programming mode is disabled if you do not press a key within 60 seconds following automatic return to the HOME position. You can also disable programming in the ACCESS CODE function by entering any number (other than the customer's code) Error messages Type of error Errors which occur during commissioning or measuring operation are displayed immediately. If two or more system or process errors occur, the error with the highest priority is the one shown on the display. The measuring system distinguishes between two types of error: System errors: This group comprises all device errors, e.g. communication errors, hardware errors, etc. see Page 115 Process errors: This group comprises all application errors, e.g. empty pipe, etc. see Page P XXXXXXXXXX #401 00:00: F06-53xxxxxx-07-xx-xx-xx-002 Fig. 45: Error messages on the display (example) 1 Error type: P = process error, S = system error 2 Error message type: $ = fault signal,! = notice message (definition: Page 115 ff.) 3 Error designation: e.g. EMPTY PIPE = measuring tube is only partly filled or completely empty 4 Error number: e.g. #401 5 Duration of most recent error occurrence (in hours, minutes and seconds) Error message type The device assigns system error and process error to two error message types (fault message or notice message) in accordance with a predefined algorithm and classifies them accordingly Page 115 ff. Serious system errors, e.g. module defects, are always identified and classed as fault messages by the measuring device. Notice message (!) The error in question has no effect on measurement currently in progress. Displayed as Exclamation mark (!), error type (S: system error, P: process error). PROFIBUS-DP/-PA Errors of this type are registered in the Transducer Block with an UNC(ERTAIN) status for the process variable in question. Fault message ( ) The error in question interrupts or stops measurement currently in progress. Displayed as Lightning flash ( ), error designation (S: system error, P: process error). PROFIBUS-DP/-PA Errors of this type are registered in the Transducer Block with a BAD status for the process variable in question. Endress+Hauser 69

70 5 Operation Promag 53 PROFIBUS-DP/-PA Confirming error messages For the sake of plant and process safety, the measuring device can be configured in such a way that fault messages () always have to be rectified and acknowledged locally by pressing.only then do the error messages disappear from the display. This option can be switched on or off by means of the ACKNOWLEDGE FAULT MES- SAGES function (see the Description of Device Functions manual). Note: Notice messages (!) do not require acknowledgment. Note, however, that they remain visible until the cause of the error has been rectified. 5.3 Communications: PROFIBUS-DP/-PA PROFIBUS-DP/-PA technology PROFIBUS (Process Field Bus) is a standardised bus system based on the European standard EN 50170, Volume 2, which has been successfully used for many years in production and process automation (chemical industry and process engineering). The PROFIBUS is a multi-master bus system with high performance, which is particularly suitable for medium to large plants. PROFIBUS-DP PROFIBUS-DP is a MASTER/SLAVE bus system. The master function is handled by an automation control system (Class 1 master) or by one or more personal computers (Class 2 master). Using cyclic data telegrams, the automation control system has full access to all of the bus stations assigned to it. With a personal computer (Class 2 master), you can, if needed, use acyclic data telegrams to exchange data with all of the connected stations. In accordance with the standard, up to 126 stations can be connected to a PROFIBUS-DP network. The PROFIBUS-DP can operate at a transmission rate of 9.6 kbit/s...12 MBit/s and, at a transmission rate of 1.5 MBit/s, can support network expansions of up to 2000 m with copper cables or 21,730 m using optical link modules. PROFIBUS-PA PROFIBUS-PA expands the PROFIBUS-DP by using an optimised transmission technology for field devices while retaining the communications functions of the PROFIBUS-DP. With the selected transmission technology, field devices can be connected via the PROFIBUS-PA to automation control systems over great distances, even in hazardous areas. PROFIBUS-PA is the communications compatible extension of PROFIBUS-DP. PROFIBUS-PA = PROFIBUS-DP + optimised transmission technology for field devices 70 Endress+Hauser

As a consequence, the Promag 53 can exchange data with automation control systems, which satisfy this standard. The integration in an automation control system must be in accordance with the PROFIBUS-PA Profile 3.0 specifications. Data transmission rate The Promag 53's maximum PROFIBUS-DP data transmission rate is 12 Mbaud. Note: The device is able to automatically determine the data transmission rate. We recommend that, before you load a new data transmission rate, you reset the device: via the function: SUPERVISION SYSTEM OPERATION SYSTEM RESET by switching the supply voltage off and back on again Information about bus terminators can be found on Page 47. Communications partner In a automation control system, the Promag always serves as a slave and can thus, depending on the type of application, exchange data with one or more masters. The master can be a automation control system, a PLC or a PC with a PROFIBUS-DP communications adapter card. Filling function In contrast to the functionality of a Promag 53 that does not support the PROFIBUS, the internal filling function is not integrated in the PROFIBUS-DP devices, since the device does not have any relay functions. However, it is still possible to use a filling function, for some applications, using the totalizer functionality. Endress+Hauser 71

Function blocks The PROFIBUS uses predefined function blocks to describe the function blocks of a device and to specify uniform data access. The function blocks implemented in the fieldbus devices provide information on the tasks which a device can perform as part of the whole automation strategy. The following blocks can be implemented in field devices in accordance with Profile 3.0: Physical Block: The Physical Block contains all the device-specific characteristics. Transducer Block (transmission block): One or more transducer blocks contain all the device measurement and device-specific parameters. In the transducer blocks, the measurement principles (e.g. flow rate and temperature) are mapped in accordance with the PROFIBUS Profile 3.0. Function Block: One or more function blocks contain the device's automation functions. We distinguish between different function blocks, e.g. Analog Input Block, Analog Output Block, Totalizer Block, etc. Each of these function blocks is used to process different applications PROFIBUS-PA system architecture PROFIBUS PA F06-xxxPBxxx-02-xx-xx-xx-000 Fig. 47: PROFIBUS-PA system architecture 1 = Automation control system, 2 = Commuwin II operating program, 3 = Segment coupler, 4 = PROFIBUS-DP RS 485 line (max. 12 MBit/s), 5 = PROFIBUS-PA IEC (max kbit/s) General information The Promag 53 can be equipped with a PROFIBUS-PA interface in accordance with the fieldbus standard PROFIBUS-DP (EN Volume 2). As a consequence, the Promag 53 can exchange data with automation control systems, which satisfy this standard. The integration in a automation control system must be in accordance with the PROFIBUS-PA Profile 3.0 specifications. The selection of the international IEC (International Electrotechnical Commission) transmission standard ensures a future-proof field installation with PROFIBUS-PA. 72 Endress+Hauser

73 Promag 53 PROFIBUS-DP/-PA 5 Operation Communications partner In an automation control system, the Promag always serves as a slave and can thus, depending on the type of application, exchange data with one or more masters. The master can be an automation control system, a PLC or a PC with a PROFIBUS-DP communications adapter card. Note: During the project planning, please remember that the Promag 53 consumes 11 ma. Caution: To prevent severe device failures (e.g. short-circuits) from having effect on the PROFIBUS-PA segment, the IEC interface is equipped with a fuse. If the fuse blows, the device is permanently disconnected from the bus. In this case, the I/O module must be replaced (see Page 123). Filling function In contrast to the functionality of a Promag flow meter that does not support the PROFIBUS, the internal filling function is not integrated in the PROFIBUS-PA devices, since the device does not have any relay functions. However, it is still possible to use a filling function, for some applications, using the totalizer functionality.

74 5 Operation Promag 53 PROFIBUS-DP/-PA Acyclic data exchange The acyclic data transmission is used to transfer parameters during the commissioning, during maintenance or to display other measured variables that are not contained in the cyclic data traffic. Generally, a distinction is made between Class 1 and Class 2 master connections. Depending on the implementation of the field device, it is possible to simultaneously establish several Class 2 connections. Theoretically, a maximum of 49 Class 2 connections can be established to the same field device. Two Classe 2 masters are permitted with a Promag. This means that two Class 2 masters can access the Promag 53 at the same time. However, you must make certain that they do not both attempt to write the same data, since otherwise the data consistency cannot be guaranteed. When a Class 2 master reads parameters, it will send an interrogation telegram to the field device specifying the field device address, the slot/index and the expected record length. The field device will answer with the requested record, if the record exists and is the correct length (byte). When a Class 2 master writes parameters, it will send the address of the field device, the slot/index, record length (byte) and the record. The field device will acknowledge this write job after completion. A Class 2 master can access the blocks that are shown in the illustration below. The parameters, which can be accessed by the Endress+Hauser operating program (Commuwin II), are shown Page 75 ff. in the form of a matrix.

These can be used for configuring both the PROFIBUS-DP/-PA parameters and all of the device-specific parameters. The predefined function blocks allow uniform access to all the network and device data. Note: A step-by-step description of the procedure for commissioning the PROFIBUS interface is given on Page 86 together with information about the configuration of device-specific parameters FieldTool operating program FieldTool is a universal service and configuration software package designed for the PROline measuring devices. Connection is by means of the PROline service interface (service adapter).

Factory setting: TOTALIZER BLOCK Select the process variable (e.g. Volume flow) with the parameter CHANNEL (V8H5). Enter the required units for the totalizer (UNIT TOTALIZER, V1H0). Configure the totalizer, e.g. for totalizing (SET TOT, V1H1). Configure the totalizer mode, e.g. balancing (TOTALIZER MODE, V1H3). 5. Configuration of the cyclic data traffic: All the relevant data is described in Chapter System Integration (see Page 90). We recommend that the Coupling Documentation be used for step-by-step configuration. This can be obtained from Endress+Hauser Process Solutions for various automation control systems and programmable logic controls. The files required for commissioning and network configuration can be obtained as described on Page Endress+Hauser

89 Esc E Promag 53 PROFIBUS-DP/-PA 6 Commissioning Rescaling the input value In the Analog Input function block the input value or input range can be scaled in accordance with the automation requirements. Example: The system unit in the Transducer Block is m 3 /h. The measurement range of the sensor is m 3 /h. The output range to the automation control system should be %. The measured value from the Transducer Block (input value) is rescaled linearly via the input scaling PV_SCALE to the desired output range OUT_SCALE. Parameter group PV_SCALE (see Description of Device Functions manual) PV_SCALE_MIN (V1H0) 0 PV_SCALE_MAX (V1H1) 30 Parameter group OUT_SCALE (see Description of Device Functions manual) OUT_SCALE_MIN (V1H3) 0 OUT_SCALE_MAX (V1H4) 100 OUT_UNIT (V1H5) [%] The result is that with an input value of, for example 15m 3 /h, a value of 50% is output via the parameter OUT. Transducer block Analog Input Function block m 3 /h PV_SCALE 100% OUT_SCALE Volume flow m 3 /h % OUT 50% m 3 /h F06-53PBxxxxx-05-xx-xx-en-002 Fig. 51: Rescaling the input value in the AI function block Note: The OUT_UNIT does not have any effect on the scaling. It should, however, be configured that it can, for example, be shown on the display. Endress+Hauser 89

90 6 Commissioning Promag 53 PROFIBUS-DP/-PA 6.4 System integration The device will be ready for system integration once commissioning has been effected via the local display or the Class 2 master (Commuwin II). The PROFIBUS-DP system will require a description of the device parameters, e.g. output data, input data, data format and supported transmission rate so that it can integrate the field devices into the bus system. This data is contained in a PROFIBUS description file (GSD file) which will be placed at the disposal of the PROFIBUS-DP master while the communication system is being commissioned. Device bitmaps, which appear as symbols in the network tree, can also be integrated. The Profil 3.0 PROFIBUS description file (GSD) allows field devices from various manufacturers to be exchanged without having to repeat the configuration process. Generally, a distinction can be made between three different types of GSD (Factory setting: manufacturer-specific GSD): Manufacturer-specific GSD: This GSD guarantees the unlimited functionality of the field device. Device-specific process parameters and functions are therefore available. Profile GSD: This GSD is different in terms of the number of Analog Input blocks (AI) and the measuring principles. If a system is configured with profile GSDs, it will be possible to exchange devices that are supplied by various manufacturers. It is, however, essential that the cyclic proces values follow the same sequence. Example: Promag 53 supports Profile GSD PA gsd (RS 485) or PA gsd (IEC ). This GSD file contains two AI blocks and a totalizer block. The first AI block is always assigned to the volume flow. This guarantees that the first measured variable agrees with the field equipment of other manufacturers. The second AI block can be freely selected as Promag 53 is capable of producing a calculated mass flow (see configuration example on Page 98 ff.). Profile GSD (multivariable) with the ID number 9760 Hex : This GSD contains all function blocks such as AI, DO, DI... This GSD is not supported by Promag. Note: A decision should be made with respect to which GSD is to be used before configuration takes place. The configuration can be altered using the local display or a Class 2 master!

91 Promag 53 PROFIBUS-DP/-PA 6 Commissioning Promag 53 supports the following GSD files: Name of device Manufacturer-specific ID No. Profile 3.0 ID No. Manufacturer-specific GSD Promag 53 PA PROFIBUS-PA (IEC ) 1527 (Hex) 9741 (Hex) EH3_1527.gsd EH3X1527.gsd Profile 3.0 GSD Type file Bitmaps PA gsd EH_ EH_1527_d.bmp/.dib EH_1527_n.bmp/.dib EH_1527_s.bmp/.dib Manufacturer-specific ID No. Profile 3.0 ID No. Manufacturer-specific GSD Promag 53 DP PROFIBUS-DP (RS 485) 1526 (Hex) 9741 (Hex) EH3_1526.gsd EH3X1526.gsd Profile 3.0 GSD Type file Bitmaps PA gsd EH_ EH_1526_d.bmp/.dib EH_1526_n.bmp/.dib EH_1526_s.bmp/.dib Each device is assigned an identification number by the Profibus User Organisation (PNO). The name of the PROFIBUS description file (GSD) is derived from this. At Endress+Hauser, this ID No. starts with the manufacturer ID 15xx. In order to ensure clarity, the GSD names (with the exception of type files) at Endress+Hauser are as follows: EH3_15xx EH3x15xx EH = Endress + Hauser 3 = Profile 3.0 _ = standard identification 15xx = ID No. EH = Endress + Hauser 3 = Profile 3.0 x = extended identification 15xx = ID No. The GSD files for all Endress+Hauser devices can be acquired in the following manner: Internet (Endress+Hauser) (Products Process Solutions PROFIBUS GSD files) Internet (PNO) (GSD library) On CD-ROM from Endress+Hauser: Order Number Structure of GSD files from Endress+Hauser In the case of the Endress+Hauser field transmitter with PROFIBUS interface, all the files which are needed for configuration are contained in one file. Once unpacked, the file will create the following structure: Version #xx stands for the corresponding device version. Device-specific bitmaps can be found in the directories BMP and DIB. The utilisation of these will depend on the configuration software that is being used. The GSD files are saved in the subdirectories Extended and Standard which can be found in the GSD folder. Information relating to the implementation of the field transmitter and any dependencies in the device software can be found in the Info folder. Please read this carefully before configuration takes place. The files with the extension *.200 have been saved in the TypDat folder. Endress+Hauser 91

92 6 Commissioning Promag 53 PROFIBUS-DP/-PA Standard and Extended formats The modules of some GSD files are transmitted with an extended identification (e.g. 0x42, 0x84, 0x08, 0x05). These GSD files can be found in the Extended folder. All GSD files that have a standard identification (e.g. 0x94) can be found in the Standard folder. When integrating field transmitters, the GSD files with the extended identification should be used first. If, however, the integration is not successful, the standard GSD should be used. This differenciation is the result of a specific implementation in the master systems. Contents of the download file from the internet and the CD-ROM: All Endress+Hauser GSD files Endress+Hauser type files Endress+Hauser bitmap files Useful information relating to the devices Working with GSD / type files The GSD files must be integrated into the automation control system. Depending on the software that is being used, the GSD files can be copied to the program-specific directory or can be read into the database using the import function within the configuration software. Example 1: In the case of the configuration software Siemens STEP 7 (Siemens PLC S7-300 / 400) the files are copied to the subdirectory...\ siemens \ step7 \ s7data \ gsd. The GSD files also contain bitmap files. These bitmap files are used to display the measuring points in image form. The bitmap files will have to be saved to the directory...\ siemens \ step7 \ s7data \ nsbmp. Example 2: If you have a PLC Siemens S5 where the PROFIBUS-DP network is configured with the configuration software COM ET 200, you will have to use the type files (x.200 files). If you are using configuration software other than that referred to above, ask your PLC manufacturer which directory you should use. Compatibility of Profile 2.0 and 3.0 devices It is possible to operate Profile 2.0 and 3.0 devices with different GSD files in one system using one DP master as the cyclic data for the automation control system in both profile versions is compatible. Note: In most cases, it is also possible to replace Profile 2.0 devices with Profile 3.0 devices of the same type without having to repeat the configuration process. This does not apply when replacing an E+H Profile 2.0 flow device with a Profile 3.0 flow device. The functionality of the new generation of devices PROline (Profile 3.0) differs from that of Profile 2.0 devices as do the names. For this reason, PROline devices (Profile 3.0) have been issued with a new identification number and as a result, an exchange of devices will involve the reconfiguration of the automation control system. 92 Endress+Hauser

93 Promag 53 PROFIBUS-DP/-PA 6 Commissioning Cyclic data exchange In the case of PROFIBUS-DP/-PA, the cyclic transmission of analog values to the automation control system is effected in data blocks of 5 bytes. The measured value is portrayed in the first 4 bytes in the form of flowing point numbers in accordance with IEEE 754 standard (see IEEE floating point number). The 5th byte contains status information pertaining to the measured value which is implemented in accordance with the Profile 3.0 specifications (see Page 90). The status will be indicated on the display of the device (see Page 65). Note: A detailed description of the data types can be found in the Slot/Index lists in the separate Description of Device Functions manual. IEEE floating point number Conversion of a hexadecimal value into an IEEE floating point number for measured value detection. The measured values are shown in numerical format IEEE-754 in the following manner and are transferred to Class 1 master: Byte n Byte n+1 Byte n+2 Byte n+3 Bit 7 Bit 6 Bit 0 Bit 7 Bit 6 Bit 0 Bit 7 Bit 0 Bit 7 Bit 0 Sign Exponents Mantisse Mantisse Mantisse Formula value = (-1) Sign * 2 (exponent -127) * (1 + Mantisse) Example: 40 F hex = binary Value = (-1) 0 * 2 ( ) * ( ) = 1 * 2 2 * ( ) = 1 * 4 * = 7.5 Endress+Hauser 93

95 Promag 53 PROFIBUS-DP/-PA 6 Commissioning Input data The following are examples of input data: volume flow, totalizers 1-3 and calculated mass flow. The current volume flow, totalizers 1-3 and calculated mass flow can be displayed on the basis of these measured variables. The calculated mass flow is derived from the volume flow and a fixed density. Data transfer from Promag to the automation control system The input and output bytes are structured in a fixed sequence. If addressing is effected automatically using the configuration program, the numerical values of the input and output bytes may deviate from the values in the following table.

The assignment of the measured variables to the respective variables can be effected using the parameter Channel, the local controls or a Class 2 master. Totalizers 1-3 can be configured individually. The following settings are possible (factory setting: volume flow in m 3 ): Off Mass flow Volume flow The parameter Channel is described in more detail in the separate Description of Device Functions manual.

96 6 Commissioning Promag 53 PROFIBUS-DP/-PA Output data Display value The display value allows you to transfer a measured value which has been calculated in the automation control system directly to the Promag. This measured value is a display value which can be assigned to the main line, the secondary line and the info line of the display. The display value contains 4 bytes measured value and 1 byte status. The status is displayed as being OK, UNCERTAIN or BAD (see Page 65). Data transfer from the automation control system to Promag 53 (display value) Output byte Process parameter Access type Comment/Data format Factory setting unit 6, 7, 8, 9 Display value write 32-bit floating point number (IEEE-754) Illustration Page 93 ao 10 Status Display value read - Note: The status can be entered freely and will be interpreted in accordance with the status coding in Profile Specification 3.0. Example: The concentration is calculated in % f (temperature/density) in the automation control system. The temperature and density status is transferred with the two cyclic measured values and can therefore be shown directly in the automation control system together with the calculated concentration. Control variables (output data) manufacturer-specific Promag 53 is capable of processing control variables during the cyclic data exchange e.g the switching on positive zero return. The following table shows the control variables (output data) that can be transferred to Promag 53. Data transfer from the automation control system to Promag 53 (Control block) Output byte Process parameter Access type Comment/Control variable Factory setting unit 11 Control variable write This parameter is manufacturer-specific and can control the following control variables: 0 1: Reserved 0 2: Positive zero return ON 0 3: Positive zero return OFF 0 4: Reserved 0 5: ECC ON 0 5: ECC OFF Note: A control variable can be executed through the cyclic data exchange each time the output byte changes from 0 to another bit pattern. It will then be necessary to reset to 0 before a further control variable can be executed. The transition from any bit pattern to 0 will not have any effect. 96 Endress+Hauser

97 Promag 53 PROFIBUS-DP/-PA 6 Commissioning Control variables for totalizers 1-3 (output data) These functions allow totalizers 1-3 to be controlled from the automation control system. The following control variables are possible: totalizing, resetting, activation of a predefined value, balancing, positive flow detection, negative flow detection and stopping of totalizing. Data transfer from the automation control system to Promag 53 (Control variables of totalizers) Output byte Process parameter Access type Comment/Control variable Factory setting unit SET_TOT 1 SET_TOT 2 SET_TOT 3 write write write The following control variables can be entered for totalizers 1-3 using these parameters. Control variable for SET_TOT: 0: Totalizing 1: Reset totalizer 2: Preset totalizer MODE_TOT 1 MODE_TOT 2 MODE_TOT 3 write write write Control variable for MODE_TOT: 0: Balancing 1: Only positive flow detection 2: Only negative flow detection 3: Stop totalizing Note: A control variable can be executed through the cyclic data exchange each time the output byte changes from one bit pattern to any other bit pattern. It will not be necessary to reset to 0 to execute a control variable. It is only possible to preset a predefined totalizer value via the local display or the Class 2 master! Example of SET_TOT and MODE_TOT: If the control variable SET_TOT is set to 1 (1 = Reset the totalizer), the value of the totalizer will be set to 0. The value of the totalizer will now be added up starting from 0. If the totalizer is to retain the value 0, it will be necessary to set the control variable MODE_TOT to 3 (3 = STOP totalizing). The totalizer will now stop adding up. The control variable SET_TOT can be set to 1 at a later point in time (1 = Reset the totalizer). Factory settings of cyclic measured variables The following measured variables are configured in Promag 53 at the factory: Volume flow Totalizer 1 (with control variable SET_TOT and MODE_TOT) Totalizer 2 (with control variable SET_TOT and MODE_TOT) Totalizer 3 (with control variable SET_TOT and MODE_TOT) Mass flow Display value (input value) Manufacturer-specific control block If all measured variables are not required, you can use the placeholder EMTY_MODULE (0x00) - which can be found in the GSD file - to deactivate individual measured variables using the configuration software of the Class 1 master. Configuration example Page 98 ff. Note: Only activate the data blocks which are to be processed in the automation control system. This will improve the data throughput rate of a PROFIBUS-DP/-PA network. A blinking double-arrow symbol will appear on the display to show that Promag 53 is communicating with the automation control system. Endress+Hauser 97

98 6 Commissioning Promag 53 PROFIBUS-DP/-PA Caution: It is essential that the following sequence be adhered to when configuring the measured variables volume flow, totalizers 1...3, mass flow, display value and control! The device will have to be reset after the new measured variables have been configured. This can be effected in either of two ways: Via the local display: HOME Block J (SUPERVISION) Group JAA (SYSTEM) Function group 804 (OPERATION) Function 8046 (SYSTEM RESET) Switch supply voltage off and then on again. System units The measured values are transmitted in system units - as described in the table on Page 95 - to the automation control system during the cyclic data exchange. If the system unit of a measured value is changed using the local display, this will not have an immediate effect on the output of the AI block (Analog Input Block) and therefore will not influence the measured value which is transmitted to the automation control system. The altered system unit of the measured value will only be transmitted to the automation control system once the SET UNIT TO BUS function in block G (BASIC FUNCTIONS) Group GBA (PROFIBUS-DP/-PA) function group 614 (OPERATION) Function 6141 (SET UNIT TO BUS) has been activated. This can also be activated with a Class 2 master (e.g. Commuwin II). Configuration examples The configuration of a PROFIBUS-DP system is normally effected in the following manner: 1. The field device (Promag 53) which is to be configured is integrated into the configuration program of the automation control system via the PROFIBUS-DP network. The GSD file is used here. The configuration software can be used to configure measured variables offline. 2. The automation control system's user program will have to be programmed now. The input and output data is controlled in the user program and the location of the measured variables is defined so that they can be processed further. An additional measured value configuration module may have to be used in the case of automation control systems which do not support the IEEE-754 floating point format. It may also be necessary to change the byte sequence (byte swapping) depending on the type of data management employed in the automation control system (littleendian format or big-endian format). 3. When configuration has been completed, this will be transferred to the automation control system in the form of a binary file. 4. The system can be started now. The automation control system will establish a connection to the configured devices. The device parameters which are relevant for the process can now be set using the Class 2 master, e.g. with Commuwin II (see Page 87). 98 Endress+Hauser
