  • Page 16: Commissioning

    Installation and commissioning must be carried out only by trained personnel in accor- dance with safety regulations. Components To commission the module, you will require the following components: • WCS-PG410 interface module • Cordset from the interface module to the read head • Connector for the PROFIBUS connection to the interface module •...

  • Page 17: Connecting The Wcs Read Head

    WCS-PG410 Commissioning Connecting the WCS Read Head If you connect several WCS read heads to one interface module, the WCS read heads must have different addresses. This will allow the programmable logic controller to allocate the data to the correct WCS read heads. If you connect only one WCS read head to an interface mod- ule, this WCS read head always receives the address 0.
  • Page 18 WCS-PG410 Commissioning Activating the RS-485 Bus Termination If the interface module is operated as the first or last physical device in an RS-485 bus or if you operate one read head on the interface module, a bus termination must be performed on this interface module.

  • Page 19: Connection To The Network

    WCS-PG410 Commissioning Activating the PROFIBUS DP Bus Termination If the interface module is operated as the first or last physical device in the PROFIBUS DP or if you operate one read head on the interface module, this interface module must have a bus ter- minator (220 ).

  • Page 34 WCS-PG410 Communication with WCS read heads Behavior of the read head in the area of the WCS3 code rail extender (WCS3-CS70-E) The read head retains the last measured end position of the first code rail segment (position = 393203) when traversing the WCS3 code rail extender. The OVL bit is set at the same time. As soon as the first valid position of the second code rail segment is read, the read head switches to the first valid position of the second code rail segment (position = 393318).

  • Page 35: Appendix

    WCS-PG410 Appendix Appendix Cable Routing in the RS-485 Bus The data cables must always form an in-line connection between the first and the last node. This in-line connection must end with a terminator. The RS-485 terminators are integrated in the WCS readers and can be switched on and off with the interface module.
  • Page 36 WCS-PG410 Appendix Reading head Reading head Interface or control (PLC) Figure 6.2 Connection of two reading heads, Version A • Version B: The interface module is located at the beginning of the data line; one WCS reader is located at the end of the data line. Both need the RS-485 terminator. The second WCS reader is connected to the line connection between the interface module and the first WCS reader through a short spur (length <1 m).
  • Page 37 WCS-PG410 Appendix Reading head Spur line (max. 1 m) Reading head Interface or control (PLC) Figure 6.3 Connection of two reading heads, Version B The wiring version used depends on which is best suited for the application. If three or four WCS readers are used on the same interface module, connect these using spurs as shown in variant B.

    WCS-PG410 Appendix Data Cable A shielded data cable with twisted-pair cores is used for the electrical connection. Pep- perl+Fuchs can supply suitable preassembled M12 single-ended female cordsets () or field- attachable M12 female connectors and data cables. Data Cable WCS-DC* There are two types of data cable available: •...
  • Page 39 WCS-PG410 Appendix Cable Length For the RS-485 data transfer path, a four-wire, shielded, twisted pair data cable must be used. One core pair is used for the supply voltage, and one pair for the RS-485 data connection. The maximum length of the cable depends on the capacitance of the data cable—core-core—for data transfer, and on the cross section of the cables for voltage supply to the read heads.
  • Page 40 WCS-PG410 Appendix Cable Overview The cable types listed below represent a selection of the types available from Pepperl+Fuchs. You can find additional cable types on our website. Note For customizable cables, observe the cable length restrictions specified by the interface specifications.
