Abstract
In a fault diagnostic system, an operator interface simultaneously displays an operations hierarchy and a components hierarchy in two separate windows. The display system is used with a model-based diagnostic system that monitors operational parameters of an industrial process. The diagnostic system identifies possible failure source components in the industrial process and the display system uses these diagnostics to display the most interesting portions of the operations hierarchy and the components hierarchy. The most interesting node, to be displayed with its subtree, is defined as the node at the lowest level of the hierarchy that is both a fault source and that has more children than than other fault sources at that level.
