Table 8.4 HART Configuration Error Message
Error message Probable cause Countermeasure
Invalid selection — Change the setting.
Value was too high Set value is too high.
Value was too low Set value is too low.
Too few data bytes received — —
In write protect mode Operation is set in the Write Protect mode. —
Lower range value too high LRV set point is too high. Change the range.
Lower range value too low LRV set point is too low.
Upper range value too high URV set point is too high.
Upper range value too low URV set point is too low.
Span too small Set span is too small.
Applied process too high Applied pressure is too high. Adjust the applied pressure.
Applied process too low Applied pressure is too low.
New lower range value pushed upper range
value over upper sensor limit
The shift of URV according to the new LRV
setting exceeds USL.
Change the URV setting within the range
of USL.
Excess correction attemted Amount of correction is too much. Adjust the amount.
Lower conversion not succeeded Characters are not convertible. e.g. % Correct the setting.
Not in fixed current mode The fixed current mode is desired but not
set in that mode.
Set in the fixed current mode.
In multidrop mode Operation is set in the multi-drop mode. —
Not write protect mode Operation is set without a password. —
Lower range value and upper range value
out of limits
URV and LRV are out of range limits. Change the setting.

(Default Value)
Description
Device Malfunction (0x80) N Field device has malfunctioned due to a hardware error or failure.
Configuration Changed* (0x40) N A modification has been made to the configuration of the field
device.
Cold Start (0x20) N A reset or self test of the field device has occurred, or power has
been removed and reapplied.
More Status Available (0x10) N Field device has more status available.
Loop Current Fixed (0x08) N Analog output and its digital representation are in fixed mode, and
not responsive to input changes.
Loop Current Saturated (0x04) S Analog output and its digital representation are outside the
operating range limits, and not responding to input.
Non-PV Out of Limits (0x02) S Process applied to the non-primary variable is outside the operating
limits of the field device.
PV Out of Limits (0x01) S Process applied to the primary variable is outside the operating
limits of the field device.
*: This flag can be reset.
For the procedure, see subsection 7.3.1.3.
