<p>A PC simulation system for simulating a ladder program (22) of a PC (programmable controller). A cursor (1) is set to a relay contact on a screen (42a) displaying the ladder program (22) to directly change the input signal. A false signal (5) thereof and an input signal (6) from the machine are subjected to the logical processing to simulate the ladder program (22). Thus, there is realized a simulation that meets the actual motion of the machine.</p> |
