    Communication between maximum 16 blocks of C series and PLC can be carried out via PLC interface unit CIT-200. The CIT-200 reads and writes the PV, SV or other data from/to the memory in the PLC via a host link unit.

  • Page 7: System Configuration

    The PLC sets and monitors the C series. RS-232C RS-422A The CIT-200 receives the data from the data memory in the PLC, CIT-200 and sends the command data to the CPT-20A. The CIT-200 receives the response data from the CPT-20A, RS-422A and sends it to the data memory in the PLC.
