Time in normal mode
how often the loop runs in auto or cascade.
Control Loop Performance Monitoring
Continuous monitoring of controller and loop health against live plant data. The output is a ranked list of the loops that cost you the most, with an example fix for each.

Why CLPM sits under APC.
APC depends on the PID loops beneath it. A controller adjusts the setpoints of those loops, so a loop that oscillates, sticks, or sits in manual limits what the controller can do. CLPM establishes and holds that base layer performance, so APC has stable loops to work through.
What CLPM measures, loop by loop
Oscillation
cycling that ripples into neighboring loops.
Valve health
stiction, hysteresis, and undersized final elements.
Variability
deviation against the loop's own baseline.
Service factor
availability of the loop through upsets and transitions.
How it works
Plant data
DCS, historian, and controller status.
CLPM engine
KPIs calculated continuously, loop by loop.
Loop scorecard
mode, oscillation, valve health, and variability.
Ranked actions
worst-performing loops first, with the example fix named.
CLPM feeds directly into APC diagnostics. Where Atlas Advisor™ is deployed, the same KPIs feed its contextual root cause work.
90-day pilot at no cost.
Atlas configures CLPM on an agreed set of loops and runs it for 90 days. There is no fee. The pilot requires some implementation work on your side.

Frequently asked questions
What does the 90-day pilot require?
Atlas configures CLPM on an agreed set of loops and runs it for 90 days at no cost. The pilot requires some implementation work on your side. The specific implementation work is agreed as part of setting up the pilot.
What does CLPM measure?
CLPM measures time in normal mode, oscillation, valve health, variability, and service factor, loop by loop. It uses live plant data to produce loop scorecards and a ranked list of actions, starting with the worst-performing loops.
How does CLPM connect to APC diagnostics and to the PID loops beneath APC?
APC adjusts the setpoints of underlying PID loops. If those loops oscillate, stick, or remain in manual, they limit APC performance. CLPM monitors and helps establish stable base-layer performance. Its KPIs feed APC diagnostics and, where Atlas Advisor™ is deployed, contextual root cause work.
