In order to solve the problems of hardware equipment, experimental duration, and limited space in the offline course of “Automated Production Line Training”, and improve the teaching quality and effectiveness, a simulation training platform for automated production lines based on PLCSIM Advanced and Simulink is designed. This platform is based on the physical training equipment in the laboratory, and uses Simulink to build a simulation model of the controlled object. Control algorithms are written in the PLCSIM Advanced simulation controller, through API communication the real-time exchange between object model and controller data is achieved and simulated. Taking the paper tension control system as an example, the construction and implementation process of the simulation training platform are introduced. Practical teaching has shown that this platform has improved the teaching effectiveness, stimulated students’ interest in practical learning, improved their ability to discover and solve complex engineering problems, and made students deeply realize the importance of teamwork and effective communication.
