<p>PROBLEM TO BE SOLVED: To obtain the reliability of a computer system by detecting abnormality of cycle software. SOLUTION: A cycle parameter setting means 2A previously sets conditions for inputting monitor parameters for monitoring the cycle software and stores the monitor parameters in a table for monitor parameter registration at each monitor timing point according to the conditions. A cycle parameter input means 3A inputs the monitor parameters stored in the table for monitor parameter registration and calculates a process time required for one cycle run. An abnormality detecting means 4 decides that the cycle software becomes abnormal if the calculated process time deviates from a predetermined prescribed range and outputs an abnormality signal to an abnormality informing means 5.</p> |
