(3) Monitoring target change when system switching occurs in a redundant system
(a)
System switching due to an alarm occurred in the control system
When system switching occurs, the CC-Link switches the station No. 0 of the master station and the station
No. 1 of the standby master station on the network.
The CC-Link module of the new control system after system switching takes over the control as the master
station.
Since the GOT monitors the master station, the monitoring target is automatically changed to the new
control system after system switching.
(b)
System switching due to a network communication error occurred in other than the CC-Link of the control
system, or due to switching by the user
When system switching occurs, the CC-Link does not switch the station No. 0 of the master station and the
station No. 1 of the standby master station on the network.
The CC-Link module of the new control system after system switching takes over the control as the
standby master station.
Since the GOT monitors the master station, the monitoring target is not automatically changed to the new
control system after system switching.
To automatically change the monitoring target of the GOT to the new control system after system switching,
switch the data link control from the standby master station to the master station by the sequence program
of the new control system.
For details of the sequence program, refer to the following manual.
