<p>PROBLEM TO BE SOLVED: To attain efficient debug at low costs. SOLUTION: In a host computer 7 for control, graphing data described with a common code common to each kind of machines are prepared by a graphic processing part 75, and variable data having attributes dependent on the kinds of machines are set by a variable setting part 74, and screen data constituted of a common code independent of the platform of a graphic control panel 5 are prepared based on the graphing data and the variable data. Then, a graphic environment and the run time environment of the screen data and the dummy operation environments of programmable logic controller 3... are risen on the host computer 7 for control, and the screen data are translated into machine words for the host computer 7 for control so as to be executed by a run time part 76. Thus, it is possible to operate the test display of marks corresponding to the states of the virtual devices 21... by a pseudo data generating part 77.</p> |
