Hello everyone;
I have Mitsubishi PLC FX3U 32M in hydropower plant governor, an error message popped up when a technician was working on an Encoder connected to it for measuring a displacement, after pressing confirm on the error message, a counter started. after some days the PLC completely stopped all functions while there is no error indication on the plc.
Any expert kindly guide me how to tackle this error, it can not be reprogrammed because settings are done during commissioning for reliable operation.
Can I put the PLC back into normal operation without affecting the set parameters?
