This paper introduces the application of virtual simulation technology control system in the PCL experimental teaching. The four storey elevator control system as a control object by use configuration software, in the process of developing virtual simulation system is described. The simulation results show that the design of the control system is feasible, the virtual elevator can run under the control of the PLC. The cost of equipment is greatly reduced, thus improving the efficiency and effect of the experiments by use virtual simulation technology.%介绍了虚拟仿真技术在PLC实验教学中的应用，利用组态软件以四层电梯控制系统为虚拟控制对象，详细地介绍了仿真系统的开发过程。通过仿真测试表明了系统设计方案的可行性，虚拟电梯在PLC的控制下运行正常。虚拟仿真技术可以有效地节约实验成本，提高实验效率，增强实验效果。
