Abstract
Abstract In a fault diagnostic system an operator interface (25, 30) simultaneously displays an operations hierarchy (60) and a components hierarchy (50) in two separate windows (200, 210). The display system is used with a model-based diagnostic system (10, 95) that monitors operational parameters of an industrial process (20). The diagnostic system (10, 95) identifies possible failure source components in the industrial process (20) an the display system (25, 30) 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 other fault sources at that level.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
88 words
A method for interactively displaying results of a diagnostic analysis system used for analyzing operation of a monitored process, the process being modeled by a component hierarchical model and a process operations hierarchical model, said method comprising the steps of simultaneously displaying in separate display windows of a display at least a portion of the hierarchical component model and at least a portion of the hierarchical process operation model, and allowing user independent scrolling in each said window independent of each other window and in two orthogonal directions.
Claim 2
Dependent Claim
45 words
The method of claim 1 further comprising the step of automatically determining a base node which serves as the root of the hierarchical model portion to be displayed in a said window, said base node initially being the highest level node for each hierarchical model.
Claim 3
Dependent Claim
64 words
The method of claim 2 wherein said automatic determining step comprises the steps of reading current data signals from the diagnostic system representing the current state of alarms at various nodes, determining from said data signals which node is a most interesting node, and displaying, using said most interesting node as the base node, a subtree of the hierarchical model in the selected window.
Claim 4
Dependent Claim
49 words
The method of claim 3 wherein said base node determining step comprises the steps of identifying the number of subnodes dependent upon a fault source base node, and selecting the base node, at a given hierarchical level, as that fault node having the largest number of nodes emanating therefrom.
Claim 5
Dependent Claim
33 words
The method of claim 4 further comprising the step of altering said display at each node at which a fault or alarm occurs to provide a visual indication of said fault or alarm.
Claim 6
Dependent Claim
40 words
The method of claim 5 further comprising the step of changing a background color of a block identifying a node having a fault or alarm condition for making a visual presentation of the fault or alarm condition to a user.
Claim 7
Dependent Claim
20 words
The method of claim 1 further comprising the step of manually scrolling said display hierarchical models in said two directions.
Claim 8
Dependent Claim
51 words
The method of claim 7 further comprising the steps of displaying each hierarchical model as a base node connected to each of its immediate children, each of said children being connected to each of their children, and continuing said display so that all levels of the hierarchical model can be displayed.
Claim 9
Dependent Claim
32 words
The method of claim 8 further comprising the step of displaying each node of the hierarchical model as a rectangular box having associated therein a text string, at least identifying the node.
Claim 10
Dependent Claim
46 words
The method of claim 9 further comprising the steps of aligning all display boxes belonging to a same hierarchical level along a first direction, and centering a parent box in said first direction with respect to its related children boxes of a next lower hierarchical level.
Claim 11
Dependent Claim
106 words
Apparatus for interactively displaying results of a diagnostic analysis system (10, 95) used fro analyzing operation of a monitored process (20), the process (20) being molded by a component hierarchical model (50) and a process operations hierarchical model (60) said apparatus comprising means (25, 30) for simultaneously displaying in separate display windows (200, 210) of a display at least a portion of the hierarchical component model (50) and at least a portion of the hierarchical process operation model (60), and means (95, 100, 130, 160) for allowing user independent scrolling in each said window (200, 210) independently of each other window and in two orthogonal directions.
Claim 12
Dependent Claim
47 words
The apparatus of claim 11 further comprising means for automatically determining a base node (255) which serves as the root of the hierarchical model portion to be displayed in a window (200, 210), said base node (255) initially being the highest level node for each hierarchical model.
Claim 13
Dependent Claim

The apparatus of claim 12 wherein said automatic determining means comprises means for reading current data signals from the diagnostic system (10, 95) representing the current state of alarms at various nodes, means for determining from said data signals which node is a most interesting node, and means for displaying, using said most interesting node as the base node, a subtree of the hierarchical model in the selected window.
Claim 14
Dependent Claim
50 words
The apparatus of claim 13 wherein said base node determining means comprises means for identifying the number of subnodes dependent upon a fault source base node, and means for selecting the base node, at a given hierarchical level, as that fault node having the largest number of nodes emanating therefrom.
Claim 15

The apparatus of claim 14 further comprising means for altering said display at each node at which a fault or alarm occurs to provide a visual indication of said fault or alarm.
Claim 16
