Config Params
Addr
The short HART address used to detect this device.
Manuf ID
The Unique ID of the Manufacturer that build the HART
device. For NMT and FMR, this is 17 - E+H.
Device Type
The unique device type specified by the HART device
manufacturer. For FMR, 0 to 49; for NMT, 180 to 199.
Device ID
The long HART ID number read from the HART device,
containing manufacturer, device type and ID number.
Preambles Cmd
The number of Preambles in the Request.
Frame Format
Type of message framing supported by the NMT.
Temp Disp Units
Temperature displayed units used by the NMT.
Level Disp Units
Level displayed units used by the NMT.
Access Code
Access code to allow the parameters in the NMT to be
changed. Code 530 unlocks the NMT while any other
code locks it.
No. of Elem
Specifies the number of measuring elements connected
to the NMT.
Type of Spacing
Indicates if the measuring elements connected to the
NMT are spaced at regular or irregular intervals:
• Regular: Element spacing value is used between
each element.
• Irregular: Allows the position of each element to be
individually set.
Elem Spacing
When element interval type is set to regular, this value
specifies the distance between each element.
Element #1 Pos through
Element #16 Pos
Position of element #1 through element #16
Bottom
The bottom point specifies the level of the lowest
temperature element inside the tank, this is then used
as the reference to determine which elements are
covered at a specific liquid level.
Level Offset
An element is only used for the average liquid
temperature calculation when it is this distance below
the liquid level.
Select Element
Specifies a particular element for calibration.
Zero
Used to adjust the average temperature calculation
zero.
Span
Used to adjust the average temperature calculation
span.
Override Short
Short Circuit Error Value: When a short-circuit fault is
detected on an element, this error value is returned
instead of the normal measured temperature.
Override Open
Open Circuit Error Value: When an open-circuit fault is
detected on an element, this error value is returned
instead of the normal measured temperature.
