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.
Always operate the device as described in these instructions to ensure that the device and
connected systems function correctly. The protection of operating personnel and plant is only
guaranteed if the device is operated in accordance with its intended use.
3.3 General safety instructions
The operator of the system is responsible in terms of planning, mounting, commissioning,
operating and maintenance.
Installation and commissioning of all devices must be performed by a trained professional only.
Independent interventions and separate modifications are dangerous and will void the warranty
and exclude the manufacturer from any liability. If serious faults occur, stop using the device.
Secure the device against inadvertent operation. In the event of repairs, send the device to
Pepperl+Fuchs.

4 Product description
4.1 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. You can connect a maximum of four WCS reading heads Type LS221
(and/or LS121) to one WCS-PNG110 interface module. If you connect several reading heads,
they must have different addresses. The number of connected reading heads is configured in
the hardware project settings.

Installation
5 Installation
5.1 Mounting
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.
The device is grounded via the mounting rail.
5.2 Electrical connection
Connector X1 is located on the top side of the interface module, connector X2 on the
underside.
Figure 5.1: Electrical connection
Note!
Grounding of the mounting rail
The mounting rail must be grounded to the switch cabinet. The connection wire must have a
cross section of at least 10 mm2.

Commissioning
6 Commissioning
6.1 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.
If only one reading head is connected, one device is connected at the beginning and one
device is connected at the end of the data line.
