摘要
针对PLC电气控制用实物方法开设实验研究遇到的被控设备难配备问题,提出了在计算机上用组态软件全真模拟PLC的控制对象,分析了用组态软件虚拟PLC被控对象仿真实验方法的可行性,给出了实验系统的结构框图和仿真程序流程图.通过以自动售货机为虚拟被控对象的应用实例,证明了该虚拟仿真实验方法,克服了真实被控对象的缺点,具有良好的效果.
In view of the difficulty of choosing real equipment to establish experiment of the PLC electric control, a new method of using configuration software to simulate the controlled object of the PLC with computer is presented. The feasibility of the application is analyzed and the system's constitution diagram and simulating program flowchart are given in this paper. Based on the example of the simulated slot machine as the controlled object, the good performance of this virtual simulating test is shown, and the defects of with the real equipment experiment are overcame.
