Abstract
In a control and monitoring signal transmission system according to the present invention, a master station that transmits and receives data to and from a control unit, a plurality of remote stations that transmit and receive data to and from the master station by a transmission synchronization method via a common transmission line, and a terminator that is connected to the common transmission line are provided, and transmitting and receiving data between the master station and the remote stations is performed by superimposing data on a frame repeatedly transmitted from the master station. The terminator extracts all of the monitoring data transmitted from the remote stations, converts the monitoring data into check data by a predetermined rule, and superimposes the check data on a check data output range provided at the end of the frame. The master station converts all of the monitoring data transmitted from the remote stations into the comparison data by the same rule as the terminator, and determines that there is an error in the transmission data when the comparison result of the check data and the comparison data is inconsistent between the check data and the comparison data.
