The main task of a real-time failure diagnosis system is to monitor the process measurements constantly and to detect and locate disturbances and failures. In this paper the use of a fault diagnosis system is studied from the process operator's point of view. A fuel feeding system of a coal-fueled power plant is presented as an example process. The user interface was built using a commercial process monitoring and control system (PMC1000 by HP). The diagnosis methods used are model-based, i.e. they utilize a mathematical model describing the physical relations of the process.
