Option
Setup
A user-configured
static pressure value
a. Set Pressure Unit to the desired unit.
b. Set Compensation Pressure to the desired value.
Polling for pressure
a. Ensure that the primary mA Output has been wired to support
HART polling.
b. Choose Online > Configure > Manual Setup > Measurements >
External Pressure/Temperature > External Polling .
c. Set Poll Control to
Poll As Primary Host
or
Poll as Secondary Host
.
d. Choose an unused polling slot.
e. Set External Tag to the HART tag of the external pressure device.
f. Set Polled Variable to
Pressure
.
Tip
•
Poll as Primary
: No other HART masters will be on the network.
•
Poll as Secondary
: Other HART masters will be on the network.
The Field Communicator is not a HART master.
A value written by
digital communica-
tions
a. Set Pressure Unit to the desired unit.
b. Perform the necessary host programming and communications
setup to write pressure data to the transmitter at appropriate in-
tervals.
Note
If the Weights & Measures application is implemented and the trans-
mitter is secured, digital communications cannot be used to write
temperature or pressure data to the transmitter.
Postrequisites
If you are using an external pressure value, verify the setup by choosing Service Tools >
Variables > External Variables and checking the value displayed for External Pressure.

Options for Pressure Measurement Unit
The transmitter provides a standard set of measurement units for Pressure Measurement
Unit. Different communications tools may use different labels for the units. In most
applications, Pressure Measurement Unit should be set to match the pressure
measurement unit used by the remote device.
