Hi, I am new to the GE PLC.
Our company hired contractors to build a plc control system for electrical interlock and changeover system around the 90s.
The system worked well until a firmware upgrade done by the maintenance team a long time ago, we have to clear the fault table every 2 weeks.
As a client, I have very limited understanding on how to use the PLC and diagnose the error.
The system is using I have no idea what the fault location it is referring to and what causes error. The system is currently using CMM311 and CPU351 modules.
Any advice or help is highly appreciated.
