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