Abstract

PURPOSE:To secure a communication between another slave station and the master station in a multidrop system, by stopping forcibly the transmission after a continuation of transmission for a certain time in case the transmission of a certain slave station makes no halt. CONSTITUTION:The time of transmission is monitored by a timer circuit that is set at a prescribed time T of transmission, and a relay driving circuit 8 is actuated at the time T. The output signal (c) of the circuit 8 is applied to a relay switch 9 to open the contact of the switch 9 and then cut off the output signal (a) of a transmitting circuit 5 from a transmission line 2.
