PURPOSE:To make high-reliability remote supervision and control possible, by supplying the output of a position to the external only when state data of this position is correct. CONSTITUTION:When a microprocessor 8 gives data of a control output to a control output unit 5, the unit 5 performs an inspection of nC1 in respect to inputted data to determine signals 5-1a-5-na of positions to be outputted and outputs signals 5-1b-5-nb having contents corresponding to these signals 5-1a-5-na. These signals 5-1b-5-nb are read onto a card 6 as data and are read into the processor 8. When data outputted to the unit 5 coincides with data from the card 6, the processor 8 drives a relay 7 to close its contact 7a. Then, the unit 5 outputs signals 5-1a-5-na. |
