<p>PURPOSE:To provide a highly reliable load control system utilizing multiplex transmission and capable of executing a control program in a state matched with a schedule instantaneously after restoration without invalidating control data received from an external terminal equipment or a host computer even when an emergency signal is received from a terminal equipment. CONSTITUTION:A load controlling controller 30 is provided with a data storing memory 32 for storing control data necessary for the execution of a control program and connected to an external setter 31, and at the time of receiving an emergency signal from any one of terminal equipments 50, temporarily stores control data transmitted from the setter 31 in the memory 32. When the emergency signal is released, the controller 30 reads out the stored control data to start the control program.</p> |
