Programming control training device

The PLC tr--ning room is an important vocational skills curriculum teaching tr--ning room for vocational and technical colleges. Programming controller principles and application experimental courses and tr--ning design and graduation design of programming controller development technology.

2. Practical ability evaluation

Through experiments, the PLC programming ability and PLC's industrial application capabilities are m--nly cultivated, and the students' design ability, practical ability, innovation ability, analysis and problem -solving ability have been explored and practiced. In teaching experiments, it also provides the actual model of industrial production. The content is close to the actual production, and it is popular with students. At the same time, it has improved the employment competitiveness of students.
