Hi Friends,
I have a strange situation at hand. I wrote a Logic for Tank Over fill (5 Tanks). When Level switch senses level, it triggers Alarm.
Same code duplicated for the 5 Tanks but I noticed that when PLC is Restarted, a False Alarm Triggers for Tank 5.
I have checked the code and I/O Assignments, everything is tight. replaced the Level switch on that Tank 5, checked wiring, used another input point on PLC (MELSEC iQ-FX5U)
Yet no joy.
Has any one here met this type of issue? or could it be PLC Battery as there is no battery in it and I could not see one locally.
I'll appreciate your input.
