(5) Monitoring target change when system switching occurs in a redundant system
When the system switching occurs, CPU (Network No.: 1, PLC station No.: 1) takes over the control of the Ethernet
network system as the control system.
The GOT automatically starts monitoring accroding to the specified system.
