5.2.9 Device Configuration and Parameter Descriptions
Table 11 lists descriptions of all parameters for a HART Transmitter with the Online tab menu path.
The same parameters may be accessed via the Shortcuts menu under the My Device tab.
Table 11 – HART Transmitter Parameters
Displays the current value of the Primary
Variable (loop PV according to the control
mode selected) in user selected engineering
units
Online/SV (CJ
temperature)
Displays the current value of the Secondary
Variable (CJ Temperature) in user selected
engineering units
Displays the current value of Analog Output
in mA
Displays the current value of transmitter
Output in %
Displays the current value of the Lower Range
Value (input which represents 0% output) in
user selected engineering units. This value
may be configured to any value within the
range as per selected loop control mode (It
will be computed depending on LTL1, UTL1,
LTL2 and UTL2.
Displays the current value of the Upper Range
Value (input which represents 100% output) in
user selected engineering units. This value
may be configured to any value within the
range as per selected loop control mode (It
will be computed depending on LTL1, UTL1,
LTL2 and UTL2.
Displays the absolute difference between the
two measured temperature inputs (Sensor 1
temperature value - Sensor 2 temperature
value).
Displays the first sensor input value
Displays the second sensor input value
Online/ Loop Control
Mode
Displays the selected loop control mode
