954 SmartServo FlexLine
For the FCI-HT software to differentiate between a HART device
malfunction and a HART device not actually installed, P1 pressure has
the entity [P1 Installed] which must be set to either <Installed> if a P1
pressure HART device is actually fitted or <Not Installed> if a P1 pressure
HART device is not actually fitted.
The Secondary and Tertiary values of a P1 pressure HART device are
not converted, and they are simply translated from the HART device to
the FlexConn environment.
7.3.7.3.3 P3 Pressure
The FCI-HT software only accepts the Primary Value of a P3 pressure
HART device in SI units kilo Pascals (kPa).
☛ Make sure the P3 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.

Table 7-5 Accepted PV unit for a P3 HART device
NOTE: The Secondary and Tertiary values of a P3 pressure HART
device may be any units.
The PV of the P3 pressure HART device is read and converted into SI
Units Pascals (Pa) within the FlexConn function PV.
The value is filtered, and the filtering factor depends on the value set in
the entity [P3 Integration time]. A higher value gives more filtering, and a
lower value gives less filtering.
The correction factor stored in the [P3 PV offset] entity is then subtracted
from the filtered value. If the [P3 PV offset] entity = 0 no offset is applied.
Depending on the [PV selected type] entity, the P3 pressure can be
displayed as either absolute pressure or relative pressure.
