Abstract
Loop status monitoring involves the declaration of deterministic trends, such as oscillations and drifting in process plant control loops. By analysing various time domain statistics associated with PI control loops, a trend can be associated as one of seven categories. The basis for doing this is given and the categorisation process is described.
