Abstract: In order to make up for the limited funds and the lack of cross table sets of colleges and universities, starting from the driving system of the cross table and the positioning control method of FX3U PLC, a virtual PLC experiment platform of cross table is developed by using KingView simulation technology. In this paper, the simulation of pulse equivalent and subdivision settings are introduced in detail from the aspects of communication settings, interface design, variables definition and command statements. And then using the two-leaf experiment, the feasibility and practicability of the virtual PLC Experiment Platform of the cross table are confirmed from the shape, size and evenness of the patterns and the time drawing the patterns in four different cases.
