Key parts of the system hardware and software design, and the system hardware, wiring diagram, PLC control I / O port allocation table and the overall program flow, etc., to achieve a plating production automation, improve productivity and reduce labor order to adapt the modern tradition industry control system, we also used based on the configuration king software system had taken on the position machine, coordinate lower position machine PLC has pleted this system realtime monitoring system function, better caused this automatic production system to integrate to the modern industry control domain in.
