Abstract

PURPOSE: To ensure to detect the occurrence of runaway in a program, by comparing and judging the number of interruption pulses fed to an operation processor with the operation confirming pulse number counted.
CONSTITUTION: When interruption pulses are fed from a timer 12, a microprocessor 10 executes the specified interruption operation processing for runaway detection, and when the result of operation is correct, a decoder 16 is accessed, one operation confirming pulse is produced every time, and the pulse is counted. At a comparison circuit 20, the pulse number N and the interruption pulse number n are compared and judged, and the result is given to a display mechanism 22 or alarm is made. When the comparison and judgement are made, a reset pulse is output from a reset circuit 24 to reset counters 14, 18.
