【摘要】 为弥补高校资金有限、十字工作台台套数不足的缺憾，从十字工作台的驱动系统和FX3U PLC定位控制方法出发，运用组态王的仿真技术开发了十字工作台虚拟PLC实验平台，分别从通信设置、画面设计、变量定义和命令语言、脉冲当量和细分设置的模拟与仿真等方面进行了详细的介绍，并运用“双片叶”实验，从4种不同情形下的图案的形状、大小、均匀度以及绘图时长等几个方面证实了该十字工作台虚拟PLC实验平台的可行性和实用性。更多还原

【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.更多还原
