Uniform identification and maintenance functions for PROFIBUS devices as an example for Web-based information systems in automation

Each PROFIBUS device contains a set of data relevant for identification and for maintenance tasks. The data are used by software tools throughout a device´s life cycle, e.g., configuration, commissioning, parameterization, diagnosis, repair, firmware update, asset management, audit trailing, etc. Since devices are optimized for specific applications, the data sets are different for different device classes. To provide uniform structures and uniform access for such data, PROFIBUS identification and maintenance functions have been defined. The paper describes a Web-based information platform that has been developed according to this specification, supporting applications by providing access to general purpose tables, to profile-specific functions, and pointers to manufacturer specific service information. The paper shows details of IM functions, as well as the Web-based information model and a demo application.
