PLC与HMI在阀门生产线改造中的应用

Design of Control System for Valve Automatic Manufacture

介绍了采用Siemens S7-300系列PLC和Pro-face人机界面为某工厂生产自动化流水线设计的方案及实现过程,给出了控制系统结构、主程序流程图及程序设计的关键,阐述了HMI的设计实现及其最终的应用效果。

This paper introduces the design and realization of automatic production line for a valve factory, using Siemens PLC S7-300 Series and Digital human machine interface Pro-face Series. We give the configuration of control system and the flow chart of the main program. We point out the key point of the programmer, and explain the design and realization of human-machine interface as well as the effect of the finally application.
