Please Find the Attached Configuration.
All PLCs are Micrologix-1400.
PLC-1 is taken as a master and only reads data from other 14 nos of PLC through MSG instruction.
Normally this configuration working fine.
But whenever power of one or more PLC(s) fails and after resuming power, the MSG instruction generates ER bit. and its not DN until the all 15 nos of PLCs are made off and then starting one by one.
Its logic of MSG is ok (i.e. it executes step by step- one PLC at a time then next and then next...)
Any Idea please?
