徴とするデータ伝送制御装置。[Claims for Utility Model Registration] A regularly used control device that sends a control signal to the looped transmission line to manage data transmission between a plurality of stations connected to the looped transmission line, and the regularly used control device. A backup control device that is switched to use when the device is abnormal; and an abnormality that detects an abnormality in the regular or backup control device and switches the loop-shaped transmission line from one of the regular or backup control devices to the other. A data transmission control device comprising a detection device is provided with a circuit in the regular or standby control device that independently sends out a control signal for managing the data transmission at intended time intervals, and detects the abnormality. After being disconnected by the detection device, the regular or standby control device is characterized in that its input and output ends are connected with a conductive wire, and the signal sent from the circuit is circulated and it is on standby. Data transmission control device.
