(5) Monitoring target change when system switching occurs in a redundant system
• Redundant system-1
When the system switching occurs, CPU (PLC station No.: 2) takes over the control of the Ethernet network
system as the control system.
The GOT automatically starts monitoring accroding to the specified system.
• Redundant system-2
When the system switching occurs, CPU (PLC station No.: 4) takes over the control of the Ethernet network
system as the control system.
The GOT automatically starts monitoring accroding to the specified system.
