Design of a PLC control system in NC wheelset assembly machine

This paper introduced a PLC-based control system in a NC wheelset assembly machine, which included the system configuration, control mode, closed-loop control technology in cylinders and communication protocol between IPC and PLC by MPI network. The PLC-based control system is feasible, and it can strengthen the system stability and improve the efficiency of products. The control system has been successfully applied in wheelset assembly machine.
