problem in the telemecanique plc p57302

[ELYAS_GH]

My system is cpu p57302 telemecanique.
While working on a system that is run once and the LED lights run off ter and err and i / o light are fixed and there is no contact with the cpu.
To resolve this problem, you can reset the cpu.
What is it:
run = off
ter = light
err = light
i / o = light

it System Error

Processor or system errors are serious errors related either to the processor (equipment or software) or to the rack bus wiring. The system can no longer operate correctly when these errors occur. They cause the PLC to stop in ERROR status, which requires a cold restart. The next cold restart will be forced in STOP status to prevent the PLC from returning to error.

replace rack or processor module
