PURPOSE:To simplify the processing of input data, by coding a selection signal for a control item in the same level step unit, in a remote monitoring and controlling device which selects the content of control by every step. CONSTITUTION:Since the variable display plate selecting switch on the operating panel 10 is not simulatneously operated for the same level switch after the station and types of devices are selected, the coding circuits 12c-12e of the variable display selecting switches are formed with the same level step unit of each variable display panel. Thus, the selection for the control items of each type is coded in the same level step unit and input to the master station 11, then the coding circuits 12a-12e can be less in number, and the number of ports of the input port group 13 is remarkably reduced. |
