Module Inhibit Function
CompactLogix controllers support the module inhibit function. See your
controller manual for details.
Whenever the output modules are inhibited, the modules enter the program
mode and the output channel is changed to the state configured for the
program mode. Whenever the input modules are inhibited, the modules
continue to provide information about changes at its inputs to the 1769
Compact Bus Master (for example, a CompactLogix controller).
