<p>PROBLEM TO BE SOLVED: To easily conduct the test of a real equipment even during the operation of a system by providing the operation of the real equipment and a sequence processing which is locally executed in a sequencer, easily switching the real equipment and a virtual equipment and to always monitoring the state. SOLUTION: A sequence program 12, a virtual equipment 13 into which the operation of the real equipment 3 and the sequence processing of a relay circuit and the like are virtually incorporated and a switching part 14 for changing over the real equipment 3 and the virtual equipment 13 are provided for the sequencer 11. The operation test using the virtual equipment 13 can be conducted during the operation of the system and the real equipment 3 and the virtual equipment 13 can easily be switched. Then, the state can always be monitored. Thus, the test becomes easy by using the virtual equipment 13 and the time of synthetic test is especially and considerably reduced. When the test of the real equipment 3 is difficult during the operation of the system, the virtual equipment 13 is used and how to operate it can be checked.</p> |
