PROBLEM TO BE SOLVED: To provide a control/supervisory signal transmission system which superimposes clock signals superimposed with power supplies with supervisory signals and control signals using a mediation station with which faults of restricting a change in the number of inputs or outputs are eliminated, and which has the mediation station having the degree of freedom of coping with an input part and an output part inside, and is easily used. SOLUTION: In the mediation station connected to a plurality of slave stations by common data signal lines and sends out the supervisory data transmitted through the slave stations from an actuator as the control data to previously correlated another actuator, the supervisory data are overwritten and stored in a storage region of the mediation station after sending out of the other surveillance data already stored in the storage region as the control data when extracted from the control signal.
