【Abstract】 By comparing with traditional laboratory, the necessity of researching and developing virtual experimental platforms for Programmable Logic Controllers(PLC) is expounded. The PLC full virtual experimental platforms based on configuration technology and OPC technology are developed using Mitsubishi FX series PLC as the foundation. The experimental project composition and functions of the basic experimental platform, motor control experimental platforms, step sequential control experimental platforms, comprehensive design experimental platforms, and complex engineering experimental platforms are mainly introduced, and the technical route of PLC virtual experimental platforms development is demonstrated, an example of stepper motor control is finally used to present the effectiveness of the PLC virtual experimental platforms. These experimental platforms hold great significance in improving the quality of PLC teaching experiments and enhancing students’ engineering practice abilities.更多还原
