Abstract: Based on YL-335B type $7-200 automatic production line training device, in order to advancewith the times and convenient teaching, using S7-1500 PLC, PLCSIM, 'TlA Portal and other software andhardware, a set of new simulation system is built. This paper proposes a kind of simulation teachingwhich is easy to realize project-driven and task implementation, and does not rely on specific equipmentwhen necessary. By issuing project assignment , students are investigated from program development andsimulation debugging operation , so as to improve students’ logical thinking and programming ability , andcomprehensively apply the knowledge learned to analyze and deal with practical problems in the engineer-ing field under complex environment , which improve the students’ cognition and adaptability to industrialautomation control. In addition, this paper can also provide some reference for the programming and de.bugging of the electromechanical integration project in the National Vocational College Skills Competition.
