C#程序与基于COM的OPC数据存取服务器交换数据研究

Study C# program to exchange data with COM based OPC data access server

研究了OPCNETCOM自动化包装器所封装的COM编排技术和OPCNET应用程序接口内的设计模式。在其基础上使用C#语言编写了一个基于.NET的OPC客户程序,与基于COM的OPC数据存取服务器交换数据。有效地实现了将遵循OPC规范的代码从COM平台移植到.NET平台。

The marshal technique from OPC NET COM Wrapper and design patterns from OPC NET API are researched. An OPC client software based on .NET is built on the basis of these technique with C# language,it is employeed to exchange data with OPC data access server based on COM.It is effectively realized to migrate the code following OPC specifications from COM plantform to .NET plantform.
