PURPOSE:To transfer selection information, which is outputted from one electronic computer, to the other electronic computer accurately with a simple constitution, by incorporating this selection information into display information, which is transmitted from a place to be controlled, together with a selection completion signal. CONSTITUTION:A selecting signal 14a from an electronic computer 1 is transmitted to a remote supervisory and control device 7 of the side to be controlled through a transmission code converter 19 and is transferred to an output circuit 32 through a receiving code converter. The output circuit 32 decodes the received selecting signal to select a designated device to be controlled. A selection completion encoding circuit 41 discriminates the position of selection completion and converts this position to a code. The code from the circuit 41 is incorporated in display information and is transmitted to a control place and is supplied to electronic computers 1 and 2. Consequently, the computer 2 grasps the selection code outputted from the computer 1 and the completion of selection. |
