PURPOSE:To release control of a system, and to prevent discrepancy between the response display of a main station and the executing state in a slave station by sending out a control on-signal toward the slave station from the main station, and thereafter, sending out automatically a control off-signal, when a response signal from the slave station does not return within a prescribed time. CONSTITUTION:A control signal ON is sent out to a slave station 2 by a processing 6 of a main station 1 side of a remote control system, and it is sent out, a timer set 11 of the processing is executed. This signal ON from the main station 1 is received and executed by processing 7 of the slave station 2, and a response signal is returned to the main station 1 through a communicating circuit from a processing 8. In such a state, when the communicating circuit extending from the slave station 2 to the direction of the main station is disconnected 10, and the response signal is not returned to the main station 1, it is detected by a processing 12 that the timer 11 has become time-up. Subsequently, a control off-signal is sent out toward the slave station 2 by a processing 13, the control of a system is released by a processing 14 of the slave station 2 side, and discrepancy between the response display of the main station 1 and the executing state in the slave station 2 side is prevented. |
