摘要
介绍了一种采用WinCC组态软件和S7-200系列PLC实现压力自动调节的方法。详细描述了PLC参数采集编程、OPC数据链接、WinCC在线趋势组态的过程,并在WinCC客户端实现系统参数设置、在线趋势显示、数据记录和存储、报警提示等功能。最后,模拟运行测试的结果表明该系统很好的完成了浮空器的压力自动调节。
A method of pressure auto control is introduced, which uses WinCC configuration software and S7-200 series PLC. The process of parameter collection program with PLC, OPC date link and trendline eonfigurationwith WinCC is described in detail, with which the function of system parameter setup, trendline display, date record and memory are achieved on WinCC client. At last, the system is tested in simulated setting and the result shows that the pressure auto control of aerostst operates well.
