HOW TO MONITOR REDUNTANT SYSTEM
This section explains the restrictions on the connection methods and other information applicable when the QCPU
redundant system is monitored by the GOT.
In a redundant system, the monitoring can be performed with the monitoring target specified as the control system or the
standby system on the GOT. By specifying the monitoring target PLC CPU as the control system of the redundant
system, the monitoring target is automatically changed to the PLC CPU in the control system when system switching
occurs.
To enable this automatic changing of the monitoring target at the GOT, settings are required in the GT Designer3.
