Construction and Practice of PLC Experimental Platform Supporting Remote Debugging

This paper puts forward the method to realize remote debugging of PLC in industrial field. By building virtual private network (VPN), the problem which traditional PLC experimental equipment can not be accessed remotely is solved, and a remote visual PLC experimental platform is built to realize remote practical training. On this basis, the online and offline hybrid PLC practice teaching reform is carried out. The reformed curriculum can better serve students’ autonomous learning, realize the iterative strengthening of thinking ability and engineering literacy, and conform to the “golden class” construction concept. The platform construction helps to promote the sharing of curriculum resources across schools and regions, and provides a reference for open laboratories.
