HART Program User Manual
Primary Variable — Displays the Primary Variable (primary value) as read from the device. The PV
is setup in the HART device and cannot be altered from the ROC. The PV is a measured
quantity originating in the process such as pressure, temperature, flow, or a value derived from
these like the HART Dynamic Variables. The user prompt message is: For information
only.
Primary Current — Displays the current of the device loop in milliamps. In the point-to-point mode,
this value will vary between 4 and 20mA. In the multi-drop mode, this value is fixed typically
at 4 milliamps. The user prompt message is: For information only.
SV Units — Displays the units configured in the device for the Secondary Variable. The user prompt
message is: For information only.
Secondary Variable — Displays the Secondary Variable as read from the device. The Secondary
Variable is setup in the HART device and cannot be altered from the ROC. The user prompt
message is: For information only.
TV Units — Displays the units configured in the device for the Tertiary Variable. The user prompt
message is: For information only.
Tertiary Variable — Displays the Tertiary Variable as read from the device. The Tertiary Variable is
setup in the HART device and cannot be altered from the ROC. The user prompt message is:
For information only.
4th Units — Displays the units configured in the device for the 4th Variable. The user prompt message
is: For information only.
4th Variable — Displays the 4th Variable as read from the device. The 4th Variable is setup in the
HART device and cannot be altered from the ROC. The user prompt message is: For
information only.
Slot Variables — This field uses a pop-up dialog box to display the Slot Units and Slot Variables
configured in the device. Refer to Figure 5-6.
