Abstract: This paper puts forward a method of implementing OPC data access between heterogeneous operating system platforms based on TCP/IP. In this method, smartly, TCP/IP communication acts as the bridge between the heterogeneous platforms, so it realizes the cross-platform OPC data access effectively and conveniently. This method can be used for universal reference towards various cross-platform OPC data access problems in industry process control field. It is successfully applied to the Alpha Magnetic System-02(AMS-02) Cryogenic Ground Support Equipment-Electric System(CGSE-ES) project, and the interface program is real-time, flexible, reliable and very easy to realize.

Key words: TCP/IP protocol, OPC communication, heterogeneous platforms, temperature data
