Handling Field Device Documentations throughout the Life Cycle of Automation Systems - Web-based Information Model and Access Methods

Field devices contain a set of data for automation and control, but also for other stages in life cycle. In addition, device-related documentation like descriptions, instructions, pictures and multimedia documents exist. Thus, the device is a central part of a complex information set, usable by software tools throughout a device´s life cycle, from configuration towards diagnosis, repair, and asset management. In heterogeneous networks containing devices from different vendors, the variety of the above-mentioned information requires a flexible, adaptable and extensible organizational structure for the information set. The paper describes such a system and presents an application example for PROFIBUS / PROFINET systems.
