Abstract

PURPOSE:To largely shorten the time required for the monitoring control by transmitting a special monitoring control signal instead of the individual monitoring signal in case of monitoring controlling the predetermined combinations. CONSTITUTION:When the input signal is applied to the input terminal 1, this change in the condition change detecting circuit 3B recognizes no output from the detection circuit 3A and orders the marking circuit 4 the formation of the monitoring control mark equivalent to the terminal to which the input of the input terminal 1 is applied. In the marking circuit 4, the input signal condition and synchronizing signal and the detection signal and the like are added to the address signal and the monitoring control mark is formed and transmitted to the receiver portion. In the receiver portion, the monitoring control mark is received and the correct address signal and the input signal conditions are recovered by the synchronizing signal, the error detecting signal and the like by the mark recovery circuit 5 and transmitted the output signals to the output terminal 7.
