A data setting system for terminal units using an optical wireless signal includes in the respective terminal units a data storing device and a receiving device for the optical wireless signal and, in a data operating device separate from the terminal units, an operating device for preparing and transmitting a setting signal to the terminal units. The setting of data in the respective terminal units employed in a remote supervisory and controlling system using a multiplex data transmission is thereby possible from a remote position from the terminal units through the optical wireless signal.

Data setting system for terminal units in remote supervisory and

A remote supervisory and controlling System for remotely supervising and controlling loads in time-divisional multiplex transmission of control 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.
