description abcdeThe present invention deals with diagnosing of a flow system, using status signals carrying information about said flow system, whereby new status information is generated, which relates to a plurality of aspects of the flow system based on said status signals and dependent on a functional model and on a set of predetermined rules. The invention comprises a diagnostic apparatus arranged to analyze the status signals for example by means of an alarm analyzer arranged to separate alarms into primary and secondary alarms, a sensor fault detector arranged to detect sensor values that probably are wrong or a fault diagnozer arranged to find the root causes for unfulfilled goals. Further the invention can comprise a failure mode analyzer arranged to detect functions that can stop working in the future or a process measurement analyzer arranged to analyze the status signals of a specific process.
