摘　　要：针对PLC实训平台的特点及受场地、成本限制等诸多问题,该文设计一种以虚拟仿真模型为控制对象的PLC实训平台。该实训平台主要包括PLC和虚拟控制对象2部分,其中,虚拟控制对象由西门子NX MCD应用模块构建,而两者的数据连接则采用OPC通信方式。结果表明,该实训平台的设计能为实践教学提供丰富的工业控制领域典型的虚拟控制对象,并能实现对控制程序的调试与仿真运行,有效地锻炼学生的PLC工程实践能力,也是对传统线下PLC实践教学的有益补充。Aiming at the characteristics of PLC training platform and the limitation of venue and cost,a PLC training platform based on virtual simulation model is designed in this paper.The training platform mainly includes two parts:PLC and virtual control object,in which the virtual control object is constructed by Siemens NX MCD application module,and the data connection between them adopts OPC communication mode.The results show that the design of the training platform can provide a wealth of typical virtual control objects in the industrial control field for practical teaching,and can realize the debugging and simulation operation of the control program,effectively exercise the students'practical ability of PLC engineering,and is also a useful supplement to the traditional offline PLC practical teaching.
