【摘要】 通过基于Microsoft.NET Framework的OPC客户端的开发,总结了OPC客户端的开发的三种方式。这三种方式是:①通过托管代码和非托管代码的互操作,在.NET Framework下访问COM组件;②基于.NET Framework开发的OPCDA类型库,开发OPC客户端;③基于.NET Framework直接开发OPCDA类型库,从而进一步开发OPC客户端。介绍了三种开发方式的特点及应用场合。更多还原

【Abstract】 Three methods of OPC client development based on Microsoft .NET Framework are presented.These methods are:(i) to call COM component in.NET Framework by each operating between managed code and not managed code.(ii)to develop OPC Client based on OPC DA class library developed in.NET Framework.(iii) to develop OPC DA class library based on.NET Framework.and develop further OPC Client.The traits of development method and application occasion are pretended.更多还原
