PROBLEM TO BE SOLVED: To provide a control system which controls an electric blind by establishing communication via a floor control unit between a central control unit and a plurality of blinds control units, and which enables the central control unit to perform recording without the lack of the state and/or history of each electric opening/closing device. SOLUTION: When instructions on the control of the electric opening/closing device 4 are issued from the central control unit 1, state calling instructions are given to a floor control unit 2 from the central control unit 1 after a lapse of corresponding predetermined time immediately after the start of the operation of the electric opening/closing device. In a plurality of memory areas of the floor control unit 2, pieces of information on the electric blind, which are sent from respective blind control units 3, are stored in the memory area with the oldest stored information in order. A notification means of the floor control unit 2 determines whether or not the state calling instructions are received. A data link is established in terms of the information on the electric blind, which is sent from the blind control unit 3 without reference to the control instructions; the central control unit 1 determines whether or not the information can be received; and the information is transmitted to the central control unit 1.
