Research on numerical control system of coiling machine based on PC-PLC

A PC-PLC numerical control system is discussed in this paper. On the one hand, OOP(Object Oriented Programming,) technology is applied in the Master, i.e. PC. Friendly interface is offered, and programmability of coiling process is realized. On the other hand, PLC is used as the slave that drives the end effector and receives control signals. All of this improves the reliability of the control system. The practice proves that this control system can be employed well in coiling machine for having advantages of operating easily, high automatization degree. Process parameters can be modified conveniently.
