| Abstract: | Aiming at stopping production problem updating transducer in the course of use of straight line wire drawing machine, the settle plan for H1000 transducer to update G7 transducer was given. The control system is mainly composed of S7 -300PLC, G7 transducer, H1000 transducer, PROFIBUS, Siemens＇ MP277 touch screen, the wiring diagram and operator interfaces of replacing transducer of two kinds of different transducer are given. The hardware configuration process and transducer parameters enacting in S7 -300 program design are expounded, and concrete communication address enacting examples are given. The transmission course of relative position inspection signals are inspected. Using indicated that the alteration of transducer G7 and H1000 can be realized by key-press of touch screen, which provide convenience for production and maintenance. |
