Product Description Use and Application The WCS-EIG310 interface module acts as an interface between the WCS read head and the EtherNet/IP controller. Data is transferred between the WCS read head and the interface mod- ule via an RS-485 interface. The data from the interface module to the control panel is trans- ferred via the EtherNet/IP protocol.

WCS-EIG310 Installation Preparing for Operation on RS-485 Interface For operation on an RS-485 interface, the terminals on connector X1 must be connected: Connect the read head to the terminal. Use the enclosed jumper to connect the terminals to each other...
WCS-EIG310 Installation Dismounting Dismounting the modules Use a suitable slot-head screwdriver for dismounting the module. Disconnect all the supply and signal lines. Figure 3.4 Dismounting Insert the screwdriver (2) into the groove of the mounting bracket (3). Press the screwdriver (2) in the specified direction until the lock on the DIN mounting rail (4) opens, see figure.
Installation and commissioning must only be carried out by trained personnel in accor- dance with safety regulations. Components To commission the module, you will require the following components: • WCS-EIG310 interface module • EDS file (the EDS file can be obtained free of charge from our website www.pepperl- fuchs.com). •...
WCS-EIG310 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 only connect one WCS read head to an interface mod- ule, this WCS read head always receives the address 0.

WCS-EIG310 Commissioning Connecting the WCS Read Head Connect the voltage supply for the WCS read head to terminals 1 and 2 of the 4-pin connector X2 on the interface module. Connect the RS-485 data cable to the WCS read head on terminals 4 and 5 of connector X1.
WCS-EIG310 Commissioning Connection to the Network The connection to EtherNet/IP is made via the two RJ45 EtherNet/IP P1 and P2 sockets on the underside of the interface module. The front socket is labeled P1 and the rear socket is labeled P2.
WCS-EIG310 Commissioning Setting the IP Address and Subnet Screen To set the device IP address, the subnet screen, and the gateway IP address, you need the WCS UGC_PF configuration tool. Downloading the Software Tool from the Internet The software tool can be downloaded from our website: www.pepperl-fuchs.com.

The configuration has now been changed according to your requirements and saved in the non-volatile memory of the interface module. Setting Rotary Switches S4 and S5 Switch off the interface module.
WCS-EIG310 Commissioning Network Settings The interface modul uses implicit messaging. Therefore, any position and speed data is mapped directly in the controller. The following figure shows the correct setting for integrating the interface module into the network. Parameters Value Input assembly...

WCS-EIG310 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.

WCS-EIG310 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).

If three or four WCS readers are used on the same interface module, connect these using spurs as shown in variant B.
WCS-EIG310 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: •...

WCS-EIG310 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.
