Abstract

A remote supervisory and controlling system for remotely supervising and controlling loads in time-divisional multiplex transmission of control units and monitor data between a central control and terminal units each connected to the central control unit through a two-wire line. Supervision and control of the overall system can be carried out from a plurality of locations so that failure of a central or host computer will not render the overall system inoperative.
