PREDICTED FAULT ANALYSIS
First Claim
1. A method of correlating candidate factors to a predicted fault in a process control system, comprising:
- obtaining a value associated with a particular factor corresponding to a process controlled in the process control system;
predicting a fault corresponding to the process when at least one of;
a predicted quality of the process passes a first threshold, the predicted quality of the process determined based on the value associated with the particular factor, ora variation of the value of the particular factor passes a second threshold;
determining a set of candidate factors corresponding to the predicted fault, the set of candidate factors including the particular factor; and
displaying, on a user interface of a computing device in communicative connection with the process control system, a correlation of at least one candidate factor of the set of candidate factors and the predicted fault.

Abstract
Example methods, apparatuses and systems to correlate candidate factors to a predicted fault in a process control system are disclosed. Techniques may include obtaining a value associated with a particular factor corresponding to a process, and predicting a fault based on the value. A set of candidate factors corresponding to the predicted fault may be determined, and a correlation between the predicted fault and at least one factor from the set may be displayed. Different sections of the display may respectively correspond to the predicted fault and to the at least one factor, and the correlation may be indicated by time aligning the different sections. Modifications to one displayed section may result in automatic modification of other sections to maintain the correlation. A user may select one or more candidate factors to be displayed, and may indicate a particular point of a particular section to obtain additional details.
