Diagram 5.104 Remote Reset Operation When Control System CPU Module Is in STOP Status and Standby System CPU Module Is
in RUN Status
(c) Precautions when executing remote reset operation
The following describes the precautions to be taken when performing remote
reset for both systems in the backup mode.
1) Remote reset when control system CPU module is in the STOP status
and standby system CPU module is in the RUN status
System switching will occur when remote reset operation is performed for the
control system CPU module when the control system CPU module is in the
STOP status and the standby system CPU module is in the RUN status.
To disable system switching at the time of remote reset, change the operation
statuses of the control system and standby system CPU modules to the STOP
status, and then perform remote reset.
