Abstract
Disclosed herein is a method for monitoring performance of equipment located in an automation environment including identifying a sequence of tasks performed by the equipment, wherein each task in the sequence is defined by a series of signals; for each task in the sequence: (a) collecting data pertaining to the series of signals; (b) determining a completion time based on the collected data; and (c) determining a difference between the determined completion time and a predetermined reference value indicative of an expected completion time; repeating (a)-(c) for a plurality of repetitions of the sequence; summing, over the plurality of repetitions of the sequence, at least some of the determined differences to calculate an accumulated variance value for each given task; and selectively generating a predictive failure indication based on the accumulated variance values.
