Figure 204: FPΣ Unit No. for PLC link
The unit number is a number assigned to a given PLC in order to identify that particular
PLC. Unit numbers should be specified in such a way that the same number is not used
for more than one PLC on the same network.
Setting method
The unit number is specified using the system registers settings in the FPWIN GR
programming tool, and the unit No. setting switch on the side of the FPΣ control unit.
Setting the unit No. setting switch to “0” makes the system register settings valid.
