Module Inhibit
Function
Some controllers support the module inhibit function. See your controller
manual for details.
Whenever the 1769sc-IF8u module is inhibited, the module continues to
provide information about changes at its inputs to the 1769 CompactBus
master (for example, a CompactLogix controller).
