My question is regarding RSLogix5000"s MSG instruction.
I am an automation tech. Our "Start_Command" bit turns on a motor. At one point, the motor was turning on without anybody triggering the Start_Command bit.
It turns out, the "Start_Command" bit was a destination element of a MSG instruction from another PLC... incorrect IP address issue.
By looking at the PLC project, was there a way for me to tell the bit was being written by another PLC through the MSG instruction?
