Product description Use and Application The WCS-PNG410 interface module acts as an interface between the WCS read head and the PROFINET IO controller. The device has two PROFINET ports. The second port can be used as an outgoing PROFINET port. Data is transferred between the WCS read head and the inter- face module via an RS-485 interface.

WCS-PNG410 Installation Installation Mounting Mounting the Modules The module is fastened to a DIN mounting rail with a width of 35 mm using a snap-on fixing method. Figure 3.1 Mounting Hook the module (1) onto the DIN mounting rail (2) from above and press it down until it snaps into place.
WCS-PNG410 Installation Electrical Connection Danger! Device damage due to incorrect installation Incorrect installation of cables and connection lines can endanger the function and the electri- cal safety of the device. • Observe the permissible core cross section of the conductor.
WCS-PNG410 Installation Connecting the Power Supply Connect the operating voltage (10 VDC...30 VDC) to terminals 1 and 2 of the 4-pin plug X2 on the interface module. In addition, note the label on the module. The "Power" LED lights up green.

WCS-PNG410 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 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-PNG410 interface module • Cordset from the interface module to the read head • Connector for the PROFINET connection to the interface module •...
WCS-PNG410 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.

WCS-PNG410 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.
WCS-PNG410 Commissioning Connection to the Network The connection to the PROFINET IO is made via the two "RJ45 PROFINET IO" sockets on the underside of the interface module. The front socket is labeled "X3 P1," and the rear socket is labeled "X3 P2."...
WCS-PNG410 Commissioning Integrating the Interface Module into the Network Warning! Risk of injury due to incorrect configuration An error during the configuration of the device can override the fail-safe function, causing a danger to people and machinery. • Ensure that the device is programmed exclusively by qualified personnel.

WCS-PNG410 Commissioning Note Ensure that the correct port is connected to the controller. If Ethernet is connected to port 2 on the physical controller, port 2 must also be connected to the interface module in the TIA portal. If the ports are not respected, an error message will appear and the interface module will not be controllable.

WCS-PNG410 Commissioning Start-up behavior of the read head After the supply voltage has been connected, the X position is set to the last valid X position and the VAL bit is set to 1. After the read head moves by approx. 5 mm, the VAL bit is set to 0 and the X position is assigned a new calculated X position.
WCS-PNG410 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 31
WCS-PNG410 Appendix • Version A: One WCS reader is located at the beginning and one WCS reader at the end of the data line. For both WCS readers, the RS-485 terminator is activated. The interface module is located between these two readers and does not have an RS-485 terminator. Each WCS reader is connected to the interface module by a separate data cable.
Page 32
WCS-PNG410 Appendix • 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).
WCS-PNG410 Appendix Behavior of the read head in the area of the WCS3 code rail exten- der (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).
WCS-PNG410 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. Cable Routing The basic prerequisite for uninterrupted data transfer is that the data cables are routed in such a way that any coupling of electromagnetic fields and interference is excluded.
400 m 250 m 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.
