P1 Pressure

The FCI-HT software only accepts the Primary Value of a P1 pressure
HART device in SI units kilo Pascals (kPa).
☛
Make sure the P1 pressure HART device is configured to output data
in kilo Pascals (kPa). If not, correctly configure as yet, by using an
appropriate HART configuration tool.

Accepted PV unit for a P1 HART device

NOTE: The Secondary and Tertiary values of a P1 pressure HART
device may be any units.
The PV of the P1 pressure HART device is read and converted into SI
Units Pascals (Pa) within the FlexConn function PV.
