<p>PROBLEM TO BE SOLVED: To provide a plant simulation system which improves its working efficiency by shortening the time needed for verification of an object controller. SOLUTION: When a controller 11 is simulated by a single verification device 1, the switch means 8 and 10 are closed and opened respectively. Then the controller 11 is separated from the device 1, and a program start adjustment means 3 functions to fast simulate a controller simulation program 7 and a plant simulation program 5 in a short time smaller than the real time. Thus the reference response characteristic is acquired in a short time for verification of the controller 1. When the controller 11 is verified, the means 8 and 10 are opened and closed respectively. Then the means 3 starts the program 5 in response to the computing cycle of the controller 11 to verify and test the controller 11 in real time. The result of this verification/test is compared with the reference response characteristic acquired previously, so that the quality of the controller 11 is verified.</p> |
