Abstract
PURPOSE: To improve the efficiency of cost reduction processing by a control circuit using a microcomputer, etc., by comparing a time set in a timer with a timer set time for a new processing request and by setting a time of higher priority.
CONSTITUTION: If microprocessor MPU1 detects processing with the 2nd time limit element from input-output circuit 7 while timer 4 is in process of counting, the current count time of timer 4 is compared with a count value up to the starting time of the 2nd processing to judge the priority, the count value up to the starting time of a processing program with high-priority time limit element is stored according to the priority of the starting address, and the program is branched to an element with higher priority, which is executed. Therefore, the time limit processing within the range that one timer allows can be performed.
