In this case, the GOT monitoring is performed by transient transmission of the CC-Link network system. Therefore, a
longer time-lag occurs for displaying objects compared with directly monitoring the PLC CPU.
For displaying objects with a shorter time-lag, set the device for RX, RY, RWw, RWr of the host station set in the CC-
Link network and execute the cyclic transmission.
For details, refer to the following.

(3) Monitoring target change when system switching occurs in a redundant system
When the system switching occurs, the GOT automatically changes the monitoring target to the PLC CPU switched
to the control system.
