(3) Restoring the system
Restore the system in the following procedure.
(a) When C Controller module is set as CPU No. 1
1) Check the faulty CPU No. and error factor on the System information screen
on the <<Module monitor>> tab of the C Controller setting utility.
2) Remove the error factor.
3) Either reset CPU No.1 or restart the multiple CPU system (power supply
ON OFF ON) for recovery.
By resetting the CPU module No. 1 or powering the multiple CPU system on again, all
the CPUs in the multiple CPU system are reset and the system is restored.
(b) When programmable controller CPU is set as CPU No. 1
1) Check the faulty CPU No. and error factor in the PLC diagnostics of GX
Developer.
2) Remove the error factor.
3) Either reset CPU No.1 or restart the multiple CPU system (power supply
ON OFF ON) for recovery.
By resetting the CPU module No. 1 or powering the multiple CPU system on again, all
the CPUs in the multiple CPU system are reset and the system is restored.
