1) The control station on the network and all normal stations can be monitored.
2) The control station on the other network and all normal stations can be monitored.
(To monitor the other network, be sure to designate the routing parameter.) 3) When the monitor target is the multi-PLC system, CPU No. 1 to No. 4 can be
monitored.
4) Devices of other stations (other than devices B and W that are allocated by the network parameter) may not allow monitoring depending on their PLC CPU.
Refer to Examples 1 to 4.in (7).
The motion controller CPU (Q Series) at other stations cannot be monitored.

5) Devices of other stations (other than devices B and W that are allocated by the network parameter) may not allow monitoring depending on their PLC CPU.
Refer to Examples 1 to 4.in (7).
(c) If connected to AnACPU/AnNCPU
