PURPOSE:To simplify the constitution of a center device and to realize multiple functions in a simple form, by securing the correspondence among each terminal device, each control key of the center device and a working state display respectively. CONSTITUTION:A center device CNT is connected to each terminal device Ti via a circuit, and the device CNT monitors and controls a single type of device connected to each device Ti. In this case, the device CNT contains the 1st pair of a control switch and a display corresponding to each device Ti and the 2nd pair of a control switch and a display corresponding to each type of device. Then a device connected to each device Ti is monitored and controlled by a combination of control switches and displays of the 1st and 2nd pairs. |
