<p>PROBLEM TO BE SOLVED: To provide a test device of a distributed control system where the time required for generating the data base of a virtual control station is shortened and deterioration of performance of an EWS(engineering work station) when the virtual control station on the EWS is operated is suppressed. SOLUTION: The device virtually conducts a communication test between the control stations of an actual machine by conducting the communication test between the virtual control stations 6. A first simulation means 51 simulating all functions of the control station is provided for the virtual control station 5 simulating the control station being a test object. A second simulation means 61 simulating only the function of a communication interface is provided for the virtual control station 6 simulating the control station except for the control station being the test object. The second simulation means 61 is provided with a communication interface means and a means having various functions processing communication data which the communication interface means receives.</p> |
