Systems and methods of industrial control processes that employ a data
matching component associated with a programming logic controller (PLC),
to substitute a plurality of collected data points with a data pattern
(e.g., a curve). Such data matching component can facilitate data
trending analysis, wherein a running industrial process can be compared
with a predetermined criteria (industrial process with optimal/desired
performance). A graphical tool (e.g., an on-screen) can be provided as
part of the matching component, to enable a user to interactively set
deviation thresholds from a predetermined criteria (e.g., optimum
performance of an industrial operation.)
