Section 8 Control Loop Asset Monitor (CLAM)
After running long enough for loop auditing to execute, if parameters in the FCE
and Loop performance read
the Asset Monitor instance may not be receiving PV, SP, and CO data. Check the
Input Records tab of the Asset Monitor and correct the Data Source Items
configuration of that Asset Monitor instance for any errors in the entry. If errors are
found in Input Records, correct the full path, source Aspect name for PV, SP and
CO and the correct tag names for PV, CO and SP in the Controller Configuration
tab.

Operation

CLAM is an automatic and non-invasive tool for PID control loop performance
monitoring. It is based on a number of performance indices monitoring the health of
the Final Control Element and the overall Loop Performance.
The principles of the calculations is described in
Figure 51. Principles of the calculations

First, a large number of performance indices are calculated. These are
advanced mathematical calculations generating numerical values that represent
the control loop performance or the health of the final control element.
