Multiplex control system with programmable logic for controlling signal transfer between controllers and one or more controlled systems

摘要

A multiplex control system has controllers for delivering control data to at least one common controlled system, and a multiplex mode switching device which is constructed to permit the logic for selecting the control data to be changeably set therein. The mode selection logic of the multiplex mode switching device can be set and changed freely by the user so that a desired logic is obtainable for the selection of the control data from the controllers, whereby the adaptability and utility of the multiplex control system are increased.
