[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for remotely controlling loads such as lighting.

[0002]

2. Description of the Related Art In a conventional system of this type, a load state and a switch state of a monitor terminal are displayed on a display unit provided outside a main operation panel, a monitor display panel, a sub operation panel, and the like. On the other hand, transmission and reception of signals between the load and the control unit are performed through a transmission line, but the normality or abnormality of the transmission line is not generally displayed.

Unlike the case of the load state or the switch state, the display section for displaying the abnormality of the transmission line does not need to be frequently seen by the operator, and therefore is not generally attached. However, the display is very convenient for the operator at the time of inspection. Therefore, it is conceivable to provide a display section separately from the load status display and the switch status display in order to display the normality or abnormality of the transmission line, but it is not so frequently used as described above, so it has a simple configuration. It is hoped that this will be realized in.
