To me, the more disturbing event and the root cause of the issue is that the PLC's power supply was overloaded and forced the PLC into "power off" mode even while input voltage was still applied. You may want to add an additional or larger PS/PM to the system. Consult the PLC hardware configuration to see how close the system is to using all available power during peak power consumption.
