基于Kingview的S7-300 PLC监控系统设计

摘要

主要讨论了基于Kingview的S7-300 PLC监控系统的硬件组成、工作原理、PLC程序设计,Kingview组态中PLC的连接、数据词典的建立、监控界面的设计等,系统最后经调试和PID参数整定后投入运行.该系统解决了PLC控制系统无法显示的缺点,具有调节及时、调节速度快、没有余差、监控方便等特点,使企业的管理更为方便快捷,提高了企业的自动控制水平.%This article focuses on the S7 -300 PLC monitoring system, including its hardware components , working principle, PLC programming, the connection to the PLC in Kingview configuration, the establishment of the database, monitoring interface and so on. The system put into operation after debugging and adjusting the PID parameters. The system solves the problems that the PLC control system can not display. It can start adjustment timely, rapidly with no error and can easy to monitor. It makes enterprise management more convenient and efficient improve the level of automatic control.
