Abstract :
On the basis of introducing the characteristics of OPC Unified Architecture and EDD (electronic device description), a framework of OPC UA server based on EDD is proposed to map field devices as nodes in address space of OPC UA server. In the framework the device object model which accords with the information model of OPC UA is presented by extracting the information from device description document. Then aimed at the characteristics of EDDL in HART, the method for transforming DD document into node object is discussed in detail. According to the method above devices of different manufacturers can be integrated into OPC UA server, and the OPC UA server can get more device management information through EDD.
