基于组态技术的PLC虚拟仿真系统设计

Design of PLC virtual simulation test system with configuration technology

提出将组态软件用于PLC仿真实验中,分析了用组态软件虚拟PLC被控对象的可行性,给出了仿真程序流程图,设计了以自动售货机为虚拟被控对象的仿真系统,通过计算机全真模拟PLC的控制对象,克服了真实被控对象的缺点.

The configuration software is applied in PLC simulating test in this paper. Feasibility of simulating PCL-controlled object with configuration software is studied. The simulating program flowchart is given. The simulated system of slot machine used as virtual controlled object is designed. The defects of true controlled object are eliminated with true simulation of PLC-controlled object in computer.
