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.

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.

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. Each reading
head is connected to the interface module by a separate data cable.

•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 < 1 m). Use bus terminal BT111 to connect the
spur.

6.3 Connecting the reading heads
If you install several WCS reading heads together on one interface module, the reading heads
must have different addresses. This will allow the PLC to allocate the data to the correct
reading heads. If you connect only one WCS reading head to the interface module, this reading
head is always given the address 0. You can connect up to four WCS reading heads to the
interface module via an RS 485 line. The default address of the reading head as delivered is 0.
If you install several WCS reading heads together on one interface module, the reading heads
