Abstract

PURPOSE:To surely execute a control request having the highest priority issued at the time of emergency, etc., by storing control requests in a memory and by devices to be controlled by successively reading out the stored control requests from the one having the highest priority. CONSTITUTION:In building control systems, etc., existence, nonexistence, etc., of controls are set at locations of a register REG of a CPU corresponding to origins of control requests. In a memory MEM a control request storing section CRM, a program storing section PM, and a search program storing section SM are formed. The storing section CRM is installed in the number corresponding to the kind of devices to be controlled, groups to be controlled, etc., and each CRM has a region which corresponds to each origin of control request and the priority and control request information of each origin of control request are written in each CPM. Moreover, the storing section SM successively searches the storing sections CPMs for existence or nonexistence of the control request information from the highest priority, and, when the first control request information is read out, stops further searchings. Therefore, the control request having the highest priority is surely executed.
