7.6 Communication Function 3: PC(PLC) link

7.6.1 PC(PLC) link

Overview
• The PC(PLC) link is an economic way of linking PLCs, using a twisted-pair cable.
• Data is shared between the PLCs using link relays (L) and link registers (LD).
• The statuses of the link relays and link registers of one PLC are automatically fed back to the other
PLCs on the same network.
• PC(PLC) link is not the default setting. Therefore, the setting of system register no. 412 must be
changed to "PC(PLC) link" in order to use this function.
• Unit numbers and link areas are allocated using the system registers.
