描述了开放式标准接口OPC(OLE For Process Control),结合MATLAB强大的工程计算能力和西门子组态软件WINCC实时采集数据的特点,设计并实现MATLAB与WINCC之间数据的动态交换。作为客户端MATLAB与服务器端WINCC之间的通信接口,OPC较好的实现了异构系统间的通讯,文中详细阐述其实现方法和具体步骤,验证了OPC技术在工业现场和系统集成应用中的实用性和有效性。
The open standards interface OPC (OLE For Process Control) is described in this article. In combination of the powerful MATLAB engineering computing capability and real-time data acquisition WINCC, the dynamic data exchange between MATLAB and WINCC is designed and realized. As the communication interface of Client ~TLAB and Server WINCC, OPC implements better communications between heterogeneous systems. This paper tells of in detail its methods and concrete steps. Furthermore, the practicality and effectiveness of OPC technology applied in the industrial field and system integration is verified.
