<p>PURPOSE:To execute a simulation to be matched to the actual movement of a machine by directly changing an input on a ladder program displayed on a screen, selecting the input and a signal from the machine, and executing the simulation. CONSTITUTION:A ladder program 22 is displayed on the screen, a cursor is directly set on the contact of a relay, and the contact is changed. Consequently, the signal to be changed is surely grasped, the efficiency of the simulation is raised, and errors are also eliminated. Further, the input signal from the display screen of the ladder program 22 and the input signal from the machine are logic-processed, for example, AND-processed, and they are used as the actual input signals. Thus, by selecting a signal 5 from the display screen and a signal 6 from the machine, the sufficient simulation can be executed.</p> |
