Data Configurations
APM directory configurations

Hello members, can somebody explain these terms, used while configuring data point.

Calculated PV
RAW VALUE
PV HIGH RANGE IN ENGINEERING UNIT
PV LOW RANGE IN ENGINEERING UNIT
PV EXTENDED ENGINEERING UNIT RANGE HIGH
PV EXTENDED ENGINEERING UNIT RANGE LOW

From the APM noted in title and the parameters asked this I assume you are asking about a Honeywell advanced process manager. Check these links out. Or search for APM manuals via Google. Feels like Honeywell has more available these days than they use to.

Some of this varies on point specifics but normally:

PVRaw is pct of the input.

Pvcalc is the value of the input converted from raw input to engineering units

PVHI is the value in engineering units at 100%

PVLo is the value in engineering units at 0%

Extended range hi lo are the values that the beyond 0% and 100%. Above/below the extended range the PV will be clamped or set to NAN- not a number

Thank You Sir for your answer. Are you working or ever worked on TDC 3000 Honeywell?
