描述了开放式标准接口OPC(OLEForProcessControl),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。
This paper describes the OLEForProcessControl which is an open standard interface and combines the powerful engineering calculation ability of MATLAB with the WINCC real-time data acquisition by Siemens to design and realize the dynamic exchange of data between MATLAB and WINCC. As the communication interface between client MATLAB and server-side WINCC, OPC better implements the communication among heterogeneous systems. The article describes its implementation method and concrete steps in detail, and verifies that OPC technology is applied in industrial field and system integration Practicality and effectiveness.
