Abstract

PURPOSE:To decrease the number of communication circuits without giving effect on a central control monitor even when a control equipment is changed by stopping the output of a control signal to a controlled system when the state of the controlled object is unchanged even when a timeout time elapses. CONSTITUTION:A control signal to a controlled object 6 is outputted based on a control command from a central monitor 1 by a control processing function section 4A. When the state of the controlled object is monitored and the state is changed, the output of the control signal to the controlled object 6 is stopped after the lapse of a specified time and when the state is unchanged even the lapse of a timeout time, the output of the control signal to the controlled object 6 is stopped. Thus, even when a control equipment is changed, no effect is given onto the central control monitor and the number of communication circuits is decreased.
