5 Display and Configuration Interface
Varec, Inc. 91
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.
