I am using RSLOGIX500 connected to Micrologix1100, sometime, Toggle bit instruction does nothing to XIC (NO) or XIO (NC) contacts, it only changes the bit value in the data file (memory), but does not make any change on the ladder program (No action on the rung )
What is the reason? and how can we resolve it?

Regards
