Connecting the WCS Reader
If you connect several WCS readers to one interface module, the WCS readers must have
different addresses. This will allow the programmable logic controller to allocate the data to the
correct WCS readers. If you only connect one WCS reader to an interface module, this WCS
reader always receives the address 0. You can connect up to 4 WCS readers to an interface
module via an RS-485 cable. Each WCS reader is supplied with the default address of 0.
Details of how to change the address of the WCS reader can be found in the configuration
instructions for the WCS reader.
The number of connected readers and their operating mode is configured in the hardware
project settings. To the Hardware Configuration, see chapter 4.4.
Setting the number of connected WCS readers
Set the number of connected WCS readers with the rotary switch S4 in accordance with the
table "Rotary switch S4."

Position of rotary switch S4 for setting the number of WCS readers
Example!
You have connected 3 readers to the interface module and want to use the velocity output.
Move the rotary switch S4 to switch position 7 and set the addresses 0,1,2 on the 3 readers.
Note!
Rotary switch S5
Rotary switch S5 has no function. Always set rotary switch S5 to position 0.
