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 only connect one WCS read head to an interface mod-
ule, this WCS read head always receives the address 0. You can connect up to WCS read
heads to an interface module via an RS-485 cable. Each WCS read head is supplied with the
default address of 0. Details of how to change the address of the WCS read head can be found
in the configuration instructions for the WCS read head.
