PURPOSE:To prevent a complete deterioration of a function which is caused by a partial fault of a monitor control line, by transmitting monitor information to a control station, receiving a corresponding command information from the control station and producing a control signal from these command information. CONSTITUTION:A monitor station monitors the state of a device to be monitored through a sensor 11. The monitor station transmits information to all control stations connected to each other via a multiplex communication control device 15 and receives corresponding command information from the control station. These command information are stored in a storage device 14, and the monitor station produces a control command from these command information and based on a prescribed rule. This control command is given to a control device 12 through an input/ output control device 13. Based on this control command, the device 12 gives a control to the device to be monitored. |
