PURPOSE: To collect the information produced before a monitor timer works and to avoid the working of a processor for an electronic computer system, by detecting an interruption due to an auxiliary timer by a discriminating circuit.
CONSTITUTION: A processor contains an interval timer 4, a monitor timer 6, an auxiliary timer 8 which is set at a desired time within the time rangesset by the timers 4 and 6 respectively, and a discriminating circuit 10 which discriminates the contents of interruption. When the circuit 10 detects an interruption due to the timer 8 with the signal B, the timers 6 and 8 are reset. Then the memory stacking is performed at that moment for the program information. Then a jog abort processing part 12 is started when a stack area is filled. Thus only the faulty jog is aborted, and the working of the processor is not stopped.
