Study on remote PLC experiment system based on web

According to requirements, a solution of remote PLC experiment system has been introduced, including total architecture, hardware and software design. We made a remote experiment in order to control simple mechanical equipment with S7-200 PLC. Then through CP243-1IT, mechanism, PLC, server and clients from internet are mutually connected. By visiting lab web and operating panel of console interface, students can finish required tests at any time. Exams indicate that the scheme of system is feasible.
