4.2 Direct CPU Connection
4.2.2 When using two GOTs
Connect a GOT to each PLC CPU to respond to the system switching.
(1) Connection method
Connect GOTs to the RS-232 interface of the control system and standby system CPU modules (Q12PRHCPU,
Q25PRHCPU) of the redundant system.
For details, refer to the following.
6. DIRECT CONNECTION TO CPU
(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 GOT cannot change the monitor target automatically in response to the
system switching.
The GOT that is connected to the control system CPU module after system switching continues the monitoring.
Different from the case using one GOT, no cable reconnection is required.
POINTPOINTPOINT
To automatically change the monitoring target after system switching using one GOT, make the Q redundant
settings.
