WCS-PNG110 Introduction Introduction Congratulations You have chosen a device manufactured by Pepperl+Fuchs. Pepperl+Fuchs develops, produces and distributes electronic sensors and interface modules for the market of automation technology on a worldwide scale. Symbols used The following symbols are used in this manual: Note! This symbol draws your attention to important information.
WCS-PNG110 Declaration of conformity Declaration of conformity CE conformity This product was developed and manufactured under observance of the applicable European standards and guidelines. Note! A declaration of conformity can be requested from the manufacturer.
Failure to observe the instructions given in this warning may result in the devices and any connected facilities or systems develop a fault or fail completely. Intended use The WCS-PNG110 interface module serves as an interface between the WCS reading heads and the PLC. Read through these instructions thoroughly. Familiarize yourself with the device before installing, mounting, or operating.
Product description Use and application The WCS-PNG110 interface module acts as an interface between the WCS reading head and the PROFINET IO. Data is transferred between the reading head and the interface module via an RS 485 interface. The data from the interface module to the PLC is transferred using the PROFIBUS protocol.
The dimensions of the WCS-PNG110 interface module are: 23 x 111 x 115 mm (W x H x D). The WCS-PNG110 interface module is attached to a 35 mm wide DIN mounting rail (EN 50022- 35) with a snap attachment.

WCS-PNG110 Installation Preparing to use the RS 485 interface Connect terminal 4 "Rx 422+" to terminal 6 "Tx 422+". Connect terminal 5 "Rx 422-" to terminal 7 "Tx 422-". Terminal Designation UB (Pwr) Operating voltage interface module/ operating voltage reading head...
WCS-PNG110 Commissioning Commissioning Cable routing in the RS 485 bus The data cable 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 reading heads and can be switched on and off with the interface module.

WCS-PNG110 Commissioning If two reading heads are attached to one interface module, there are two wiring versions: • Version A: One reading head is located at the beginning and one reading head at the end of the data line. With two reading heads, the RS 485 terminator is activated. The interface module is located between these two heads and does not have an RS 485 terminator.

WCS-PNG110 Commissioning • Version B: The interface module is located at the beginning of the data line; one reading head is located at the end of the data line. Both need the RS 485 terminator. The second reading head is connected to the line connection between the interface module and the first reading head through a short spur (length <...
Commissioning Meaning of LEDs Power: The "Power" LED lights up green: The WCS-PNG110 interface module is correctly connected with the power supply. 1, 2, 4, 8 and State: The "State" LED lights up or flashes green: Data exchange takes place with the reading heads.
Connect the RS 485 data line to the reading head on terminals 4 and 5 of connector X1. If you operate the WCS-PNG110 interface module at the beginning or end of the RS 485 bus, you must activate the RS 485 terminator.
WCS-PNG110 Commissioning Connecting the WCS-PNG110 to the network The connection to the PROFINET IO is made via the "RJ 45 PROFINET IO" connector on the underside of the interface module. Terminal Designation Transmission line + Transmission line - Receive line + Receive line - Table 6.2: Terminal of the 8-pin "RJ 45 PROFINET IO"...

F0=1: The reading head sends the result of the diagnostic function. For more information on the function of F0 see chapter 7. Data format of WCS-PNG110 interface module for the reading heads In "only Position" mode, 4 bytes are reserved for each reading head.
WCS-PNG110 Appendix Appendix Meaning of F0 Function number for reading head Send position value Send diagnosis result Diagnostic function F0=1 The reading head can be requested to perform a diagnosis of the photoelectrics by means of the request byte. For this purpose, the reading head must be located outside of the code rail.
