Research on Field Device Integration Model

Each field device contains a great deal of automation control information, which is used for different stages of software tools throughout a device´s life cycle from the configuration towards operation, maintenance, and asset management. By analyzing functions and structure of software tools throughout a device´s life cycle and using object-oriented technology for modeling, this paper establishes a field device integration model with structured organization of user interfaces, data, parameters, services, and events in order to provide understanding of features of field device integration and meet needs of achieving field device integration and device interoperability for software tools. The model can be converted into a corresponding field device description, so the paper presents methods that the field device integration model is applied to the current major device integration technologies in the end.
