ABSTRACT:
An operator interface for a programmable controller is disclosed. The programmable controller has a plurality of discrete input terminals, a discrete input switch coupled to one of the input terminals, a plurality of discrete output terminals, a processor and a memory. The memory stores operating system software processed by the processor and comprises relay logic. The processor controls states of the output terminals in response to states of the input terminals and the relay logic. The operator interface selectively operatively coupled the input switch to a desired one of the output terminals and comprises an operator actuable control switch coupled to another one of the input terminals and an element responsive to actuation of the control switch for selectively coupling the input switch to the selected one of the output terminals, the coupling element comprising the operating system software processed by the processor.
