26 1. Installation 1.4 Connecting the fieldbus There are one (FB20) or two (FB21) connections on the node for connecting the Interbus. One connection is for the incoming line; the other is intended for the continuing bus cable. Observe the differences in the remote bus, which are listed below. Note Faulty installation and high transmission rates may cause data transmission errors as a result of signal attenuations. Transmission errors can be caused by: transmission over distances which are too long inappropriate cables. Observe the cable specifications! Obtain information about the cable type to be used from the manual for the interface module or from the Interbus installation manual System structure on the remote bus The CPX terminal with bus node FB20/21 is a fibre-optic remote bus participant on the Interbus with Rugged Line connection technology. Dependent on the modules used, it reacts to the remote bus like a fibre-optic bus terminal with integrated I/Os and it must be addressed accordingly. Note Commissioning on the remote bus can only take place if all slaves are completely connected, or if they are bridged by means of a software setting. The CPX terminal requires a 24 V DC power supply. This is supplied via the Rugged Line plug. It is possible to supply and switch off separately the valve terminal outputs/valves. 1-12

30 1. Installation Connecting the fibre optic cable Preparing Note Only use the fibre optic cable from Phoenix Contact (see Appendix A, Tab. A/5). Only the following procedure is suitable for removing the outer red insulation coating: The fibre optic cable must be at least 12 cm longer than required, as the cable must be shortened by this length when the insulation is removed (see following pos. 7). Proceed as follows: 1. The cable must be cut in a longitudinal direction. The cable cross-section must be turned so that the longitudinal cut is on the side facing the aramide yarn. 2. Place the cable cutter (KAMES LWL) on the cable coating approx. 10 cm from the end of the cable and pull it in a longitudinal direction (see Fig. 1/5, diagram A). If necessary, repeat the step until the cable coating has been cut. 3. Loosen the strain relief (aramide yarn) from the cable coating which has been cut open (see Fig. 1/5, diagram B). 4. Wind the aramide yarn onto a mandril (e.g. screwdriver, pliers) and protect it against rolling off (see Fig. 1/5, diagram C). 5. Tear open the outer red cable coating approx. a further 15 cm with the aramide yarn without bending the cable (see Fig. 1/5, diagram C). 1-16

31 1. Installation Note The two individual cores must not be damaged. 6. Use a sharp diagonal cutter to cut off the outer red cable coating and the strain relief at the start of the cut area, without damaging the two individual cores (see Fig. 1/5, diagram D). 7. Shorten the individual cores by 12 cm, as this part may have been damaged when the insulation was removed with the cable cutter (see Fig. 1/5, diagram D). A 1 B C D 1 Cable stripper Kames 1 from Phoenix Contact Fig. 1/5: Removing the outer cable insulation 1-17

32 1. Installation Connecting Proceed as follows: 1. Break through the sealing rubber with a screwdriver. 2. Place the Quickon screw, the clamping box and the sealing rubber on the polymer fibre cable. The sealing rubber must be flush with the edge of the insulation (see Fig. 1/6, diagram A). 3. Push both black cores through the splice ring. The smooth side of the splice ring must face towards the cable. Note Note the marking IN/OUT on the splice ring. Cross the individual cores on the opposite splice ring (see Fig. 1/6, Pos. 5 ). If you have inserted the individual cores incorrectly in the splice ring, you must not turn the cores, as they will then be damaged. 4. Push both black cores through the appropriate opening in the Rugged Line plug until they project at the other end (see Fig. 1/6, diagram B). 1-18

33 1. Installation Tighten the Quickon screw with the fibre cutter (Phoenix Contact, type IBS RL FOC). This provides strain relief (see Fig. 1/6, diagram C). 6. Push the fibre cutter as far as possible onto the projecting cores on the Rugged Line plug (see Fig. 1/6, diagram D). 7. Cut off the individual cores.

34 1. Installation Checking the fibre optic cable connection When a fibre optic cable has been installed, you can check the optical performance in front of the receiving device with a fibre optical measuring unit (see Appendix A, Tab. A/5). Proceed as follows: 1. Clean the optical active range of the measuring unit with a clean cloth free of fluff. 2. Screw the measuring unit adapter onto the measuring unit. 3. Place the measuring unit with the measuring unit adapter on the longer of the two remote bus connections on the Rugged Line plug. 4. Set the measuring unit to 660 nm. 5. Measure the optical performance. For reliable data transmission, the measured level must not exceed a value of -3.6 dbm or drop below a value of dbm. This level takes into account the performance drift of the send and receive components and a system reserve of 3 db. 1-20

36 1. Installation Fieldbus cable Bus length Details concerning the bus length can be found in Appendix A. Note If the valve terminal is mounted into a moving part of a machine, the fieldbus cable on the moving part must be provided with strain relief. Please also observe the relevant regulations in EN part Fieldbus baud rate and fieldbus length The maximum permissible fieldbus length is dependent on thefibre-opticcableused.thebaudrateis500or 2000 kbit s. 1-22

37 1. Installation 1.5 Pin assignment of power supply Warning Only use PELV circuits as per IEC/EN (protective extra-low voltage, PELV) for the electrical power supply. Observe also the general requirements of IEC/DIN EN for PELV circuits. Only use voltage sources, which guarantee reliable electrical isolation of the operating voltage as per IEC/EN The use of PELV circuits ensures protection from electric shock (protection from direct and indirect contact) in accordance with IEC/EN (Electrical equipment of machines, General requirements). The current consumption of a CPX terminal depends on the number and type of integrated modules and components. Observe the information on power supply and the required earthing measures in the CPX system description. 1-23

Note Use a power supply cable 5 x 1.5 mm 2, e.g. from Phoenix Contact (see Appendix A, Tab. A/5). The numbers printed on this cable correspond to the numbering on the splice ringoftheruggedlineplug. Proceed as follows: 1. Break through the sealing rubber with a screwdriver. 2. Push the Quickon screw, the clamping box and the sealing rubber over the power supply cable (see Fig. 1/8 diagram A). 3. Remove the insulation coating over a length of approx. 10 cm. 4. Push first the sealing rubber to the edge of the insulation, then push the clamping box onto the sealing rubber (see Fig. 1/8, diagram B). This forms the strain relief for the cable. 1-25

40 1. Installation 5. Push the ends of the cable cores into the appropriate openings on the splice ring (see Fig. 1/8, diagram C). The numbers printed on the cable correspond to the numbering on the splice ring. 6. Pull hard on the ends of the cores. 7. Cut off the projecting ends of the cores. Make sure that the ends of the cores are flush with the splice ring, do not project, and are not too short (see Fig. 1/8, diagram D). 8. Insert the ready-to-use cable into the appropriate connection on the Rugged Line plug (see Fig. 1/8, diagram E). 9. Turn the ready-to-use cable until the coding lugs of the splice ring fit exactly into the appropriate guides of the Rugged Line plug. 10. Tighten the Quickon screw with the fibre cutter (see Fig. 1/8, diagram F). The insulation will then be cut and the electrical contact restored. Note If you wish to connect the cable cores again, you must cut them again, as otherwise the electrical contact cannot be guaranteed. 1-26

Commissioning Note If two addresses are assigned for one valve location, the following applies: lower-value address: pilot solenoid 14 higher-value address: pilot solenoid 12 Address assignment on the Interbus The address assignment (processing data assignment) of the inputs and outputs of a CPX terminal on the Interbus depends aboveallontheinterbusmoduleandonthecontrolsystem used. Caution There are different address assignments on the Interbus. The reason for this is the assignment of the processing data within the Interbus module. When assigning the addresses, note the position of the high and low bytes, as the position of these bytes may be swapped in conjunction with some control systems. You can then avoid faults in addressing the inputs/outputs. Further details on addressing can be found in the manuals for your controller and for the Interbus module. The following examples provide basic information on the different address assignments and the positions of the low byte (n) and the high byte (n+1) with various controllers. There are two modes: IntheSiemens mode the lower-value input or output byte (byte n) is mapped on inputs or outputs , byte n+1 on the next inputs or outputs ( ) etc. 2-9

54 2. Commissioning IntheStandard mode the lower-value input or output byte (byte n) is mapped on inputs or outputs , byte n+1 on the inputs or outputs This allocation also applies to the bytes of diagnostics M2 M4. In section you will find instructions on addressing with the CMD software (processing data assignment) and on modifying the position of the low and high bytes ( byte swap ). Note Thebyteswapcaneither be set via DIL switch 1.3 or with the help of the CMD software. If the byte swap is set via DIL switch and CMD, then the settings override each other! Examples for the address assignment of the CPX terminal The following examples show the assignment of the input and output bytes to the individual modules. In the examples the following applies: Configured input address: IB20 Configured output address: OB20 The address assignment is represented both in the Siemens mode and in the Standard mode. The address assignment within the individual I/O modules canbefoundinthemanualforthei/omodules. The address assignment within the pneumatic modules can be found in the manual for the valve terminal pneumatics. 2-10

60 2. Commissioning Address assignment after extension/conversion A speciality of the CPX terminal is its flexibility. If the demands placed on the machine change, the equipment fitted on the CPX terminal can also be modified. Caution If the CPX terminal is extended or converted at a later stage, the input/output addresses may be shifted. This applies in the following cases: if additional modules are inserted between existing modules if existing modules are removed or replaced by other modules which have more or fewer input/output addresses VTSA... manifold sub-bases for monostable valves are replaced by manifold sub-bases for bistable valves or vice versa (see pneumatics manual). Additional VTSA... manifold sub-bases are inserted between existing bases. The configured addresses of the pneumatic interface are modified. Note If the configuration is modified, the addresses of diagnostics M3 or M4 may also be shifted if necessary! 2-16

61 2. Commissioning The following diagram shows the changes which occur to the address assignment when the equipment fitted in example 1 is modified.

63 2. Commissioning Bus configuration and addressing General instructions on commissioning Before commissioning or programming, compile a configuration list of all connected fieldbus slaves. On the basis of this list you can: carry out a comparison between NOMINAL and ACTUAL configurations, in order to recognize connection faults. access these specifications during the syntax check of a program, in order to avoid addressing faults Configuration of the CPX terminal demands a very accurate procedure, as different configuration specifications are sometimes necessary for each slave on the Interbus, due to the modular structure. Note here the specifications in the sections which follow. 2-19

64 2. Commissioning Switching on the power supply Note Note also the instructions in the manual for your controller with Interbus module. When the controller with Interbus module is switched on, it automatically carries out a comparison between the NOMINAL and ACTUAL configurations. It is important for this configuration run that: the configuration specifications are complete and correct the fieldbus slaves are supplied with power, in order that they can be recognised when the ACTUAL configuration is ascertained. Therefore, switch on the power supply for all the fieldbus slaves simultaneously, e.g. via a central switch. Alternatively switch on the power supply in the following sequence: 1. First the power supply for all the fieldbus slaves, 2. then the power supply for the controller. 2-20

65 2. Commissioning Bus configuration with the CMD software This section describes as an example the main steps within the CMD software for inserting a CPX terminal in your project. A general and comprehensive description can be found in the relevant manual for the CMD software. In the following it is assumed that the user is familiar with the contents of the CMD manual. Note Note that software packages are often updated, so that modifications to the software may not yet be taken into accountinthismanual. The examples used here for the screen displays have been taken from CMD software version

66 2. Commissioning Inserting with Ident. code Proceed as follows: 1. Click on the module with the right-hand mouse button. 2. Select the command Insert with ID code... in the context menu. Fig. 2/8: Inserting bus slaves with Ident. code 2-22

Observe the following: Note Round up the number of inputs and/or outputs to the next word limit (16, 32, 48, 64, 80 or 96). If the number of input bits differs from the number of output bits, the greater number is in each case decisive for the entry of the process data channel bits. 2-24

69 2. Commissioning Insert description of slave In the following dialogue window you can describe the slave and enter specific information, e.g. station name and picture of the slave. Fig. 2/10: Dialogue window Insert Device Description 6. Profile number: The CPX terminal corresponds to the Interbus I/O profile 12 H. Enter this value in the field Profile Number. 7. Interface type: Interface type Universal is preset. This setting can be accepted. Alternatively, by actuating the Interface Type button you can open a dialogue window in which you can set the type Remote bus. 2-25

70 2. Commissioning 8. If required, you can enter appropriate terms for identifying the CPX terminal under Station Name, Device Name, Manufacturer Name and Device Type. 9. Representation: You can adapt the representation of the CPX terminal individually in the CMD software. However, this is not absolutely necessary for commissioning. By actuating the Presentation button you can open a dialogue window in which you can set a specific icon for the CPX terminal. The specific icons for CPX terminals can be found online Firmware and drivers. Copy the file CPX-21.ico into the CMD directory \PICTURE\. Actuate the Select... button in the Presentation dialogue window. Select the entry Icons (*.ico) under File type. Fig. 2/11: Dialogue window Change Icon Collection 2-26

72 2. Commissioning Fig. 2/13: Example inserted CPX terminal 2-28

73 2. Commissioning Bus configuration without CMD software Logical addressing In the case of the bus configuration without CMD software, the following specifications must be known or ascertained for each bus slave. Configure the CPX terminal as follows: ID code (Ident. code) CPX terminal only with outputs 1) :IDcode1 D CPX terminal only with inputs:idcode2 D CPX terminal with inputs and outputs 1) :IDcode3 D 1) Valve coils and/or electric outputs Process data channel: Calculate the number of I/Os per valve terminal. The number of inputs and/or outputs must be rounded up to the next word limit. If the number of input bits differs from the number of output bits, the greater number is in each case decisive for the entry of the process data channel bits. Please note the following: Diagnostics mode 3 occupies an additional 16 inputs. Diagnostics mode 2 and 4 occupy an additional 32 inputs. Assign logical IN and OUT addresses to each slave. 2-29

74 2. Commissioning Process data entry via the CMD software The CMD software offers as from version 4 the possibility of assigning any input/output in the PLC/IPC bit-by-bit to each input/output of a CPX terminal within the configured address range. Proceed as follows: 1. Insert a CPX terminal into your bus structure (necessary steps see section Bus configuration with the CMD software ). 2. Select the command Process Data in the context menu of the CPX terminal. 2-30

75 2. Commissioning Fig. 2/14: Open the dialogue window Process Data 2-31

76 2. Commissioning You can define the I/O addresses in the following dialogue window. In this way you can adapt the I/Os of the CPX terminal to the PLC used. The following diagram shows the byte-by-byte assignment for a Siemens S7: Fig. 2/15: Enter process data Example for Siemens mode 2-32

77 2. Commissioning If necessary, swap the high byte and the low byte (byte swap). Note You can select the data format in two ways: EitherviaDILswitch1.3(seeTab.1/2)orviatheCMD software. Selection of data format via the CMD software: InordertocorrectthebyteassignmentintheSiemensand Standard modes, it will suffice to assign the appropriate I/O address to each byte. Individual I/O assignment at bit level is only necessary in rare cases. The following dialogue window shows the entries required for swappingtheassignmentofthehighbyteandthelowbyte (example: byte swap for Standard mode ). Fig. 2/16: Modification of the I/O assignment (byte swap) Example for Standard mode 2-33

78 2. Commissioning 2.2 Parameterisation You can set the reaction of the CPX terminal as well as the reaction of individual modules and channels by parameterisation. A distinction is made between the following parameterisations: System parameterisation, e.g.: switching off fault messages, etc. Module parameterisation (module and channel-specific), e. g.: monitoring, settings in the event of errors, settings for Forcing. Parameters of the CPX terminal A description of the functions of the individual parameters canbefoundinthecpxsystemmanual. Which module parameters are available for the various modules can be found in the manual for the relevant module (e.g. manual for CPX I/O modules (P.BE-CPX-EA-...)). 2-34

79 2. Commissioning Prerequisites for parameterisation With the system parameter System start you can influence the starting reaction. If possible select the setting System start with default parametrisation and current CPX expansion. The desired parameterisation can then be carried out in the initialisation phase or user-controlled. Note The CPX terminal can only be parameterised if the system parameter System start has the setting System start with default parametrisation and current CPX expansion. If the M LED lights up permanently after the system start, then System start with saved parametrisation and saved CPX expansion is set. In this case, no other parameterisation can be carried out. Caution In the case of CPX terminals on which the M LED lights up permanently, the parameterisation will not be restored automatically by the higher-order system if the CPX terminal is replaced during servicing. In these cases, check before replacement to see which settings are required and carry out these settings. 2-35
