PURPOSE:To shorten the time required for pattern control by converting a select signal for the pattern control from a central controller into individual control signals by gateway devices. CONSTITUTION:The central control unit 4 sends out a pattern control signal to a signal transmission line 5 and the select signal for the pattern control from the central controller 4 is converted into the individual control signals by the gateway devices 10a and 10b connected to the signal transmission line 5. Then respective terminal devices 3 and 3 input the individual control signals and performs specific processing according to the contents of control data. Therefore, the control signal need not be sent to the terminal devices 3 and 3 individually from the central control unit 4 in the pattern control and the processing for individual control is decentralized. Consequently, the time required for the pattern control over loads to be controlled can be reduced. |
