ABSTRACT:
A time-division multiplexing system includes a control unit and multiple I/O units. The control unit generates timing signals that select one of the I/O units to be enabled at any time, and the timing signals include clock signals that index selected channels within the enabled I/O unit. The control unit stores both Boolean logical relationships among the channels of the multiplex system and functional names for the channels of the multiplex system in a reprogrammable memory. The control unit can be programmed with a programming system that uses a graphical user interface to make the programming operation simple and reliable.
