| Abstract: | This paper introduces the OPC technology, and it＇s communication principle. The typical frame of OPC application program is also introduced. The OPC client is exploited that communicates with OPC server through OPC automation interfaces with OPC 2.05 specification, and client data acquisition is implemented. It is pointed out that OPC technology will be the direction of the development of communication standard for many fields besides process control. |
