利用OPC实现VC应用程序与WinCC的数据交换

OPC-Based Data Communication between VC Application Program and WinCC

本文基于OPC(OLE for Process Control)技术的基本原理,重点介绍了通过组态软件WinCC实现VC应用程序与一级自动化系统的通讯方法。详细介绍了WinCC作为OPC服务器的设置方法和VC编写OPC客户端程序的实现代码。

Based on the principle of OPC （OLE for Process Control）, the paper introduces a communication method between VC and first class automation system through WinCC, especially the set method of WinCC as the server of OPC, and the code structure using VC to program the end users.
