OPC技术解决问题的方法
    OPC是为使不同供应厂商的设备和应用程序之间的软件接口标准化，以及使其问的数据交换更加简单化而提出的。作为结果可向用户提供不依赖于特定开发语言和开发环境的可以自由组合使用的过程控制软件组件产品。利用OPC的系统由按照应用程序(客户程序)的要求提供数据采集服务的OPC服务器、使用OPC服务器所必需的OPC接口，以及接受服务的OPC应用程序所构成。OPC服务器按照各供应厂商的硬件所开发，因此可以吸收各供应厂商硬件和系统的差异，从而实现不依赖于硬件的系统构成。同时利用一种叫做Variant的数据类型，可以不依赖于硬件中同有的数据类型，按照应用程序的要求提供数据格式。利用OPC 使接口标准化可以构成如图2所示的系统。
