Direct CPU Connection
This section describes the direct CPU connection by which a GOT is connected to a PLC CPU in the redundant system.
Two methods for the CPU direct connection, using one or two GOTs, are available.
4.2.1
When using one GOT
(1) Connection method
Connect the GOT to the RS-232 interface of the control system CPU module (Q12PRHCPU, Q25PRHCPU) of
the redundant system.
For details, refer to the following.
(2) GT Designer3 setting
Set GT Designer3 as follows.
(3) Monitoring target change when system switching occurs in a redundant system
When the system switching occurs, the PLC CPU (other station) of the control system after system switching
takes over the host station operation.
Since the GOT monitors the control system, the monitoring target is automatically changed to other station.

POINT
To monitor the control system without Q redundant setting
If the system switching occurs when the Q redundant setting is not made, the GOT cannot change the monitoring
target at the occurrence of system switching since it monitors the connected PLC CPU (host station).
As a countermeasure, change the cable connection from the PLC CPU in the previous control system to the control
system after system switching.
