This paper uses the idea of object-oriented software engineering to abstract field devices, variables, and the OPC tags of 3G industrial network as objects. And, it uses the theory of modular software engineering to design and implement OPC server for 3G industrial network. In order to accomplish the asynchronous communication of 3G network, event-based approach is used, and complete the data acquisition and write back of 3G industrial nodes. By the approach of using third-party dynamic link library, the processes of developing OPC sever are simplified, and help complete the development OPC server. After the validation of the standard OPC client-side, it suggested that the design and development of this OPC server meet the requirements of OPC specification.
