PM866 controller is going to fault mode
We have PM866 controller with CI867. System was running fine from last 2 month but as on today the controller went into Fault mode with reason unknown. We had to power restart (Off & then On) the controller to make it normal again.
We are using this controller to read Modbus data over TCP through CI867. Cyclic load on controller is 60%.
I have attached here the Logs.
Can some one please help to identify the issue so that it does not repeat.
* Is there any power fluctuation observed at that time?
* The below is an extract from controller log:
