基于OPC服务器和网站应用程序的可编程逻辑控制器

Monitoring PLC Based on OPC Server and Web Application Process

各大主流PLC厂家的上位机组态软件都支持建立OPC服务器。用微软公司的Visual C#编写一个Web应用程序作为PLC的监控画面,建立此Web应用程序与OPC服务器的通讯,并把它在Internet上发布。基于Web应用程序的优点,可以使用电脑、手机等任意浏览器(无须安装控件)通过Internet像访问普通网页一样访问画面来监控PLC。

All of the mainstream configuration software supports the establishment of OPC servers. A web application program can be written by using Microsoft Visual C # as the PLC＇s monitoring picture, the communication between web application and the OPC server can be established and it can be published on the Internet. Based on the advantages of Web applications, you can use your computer, mobile phone, etc. any browser （no need to install controls） Internet access as access to the same screen through ordinary web to monitor PLC.
