C-6 Additional HART Protocol Information
Table C.4 HART Field Device Error Codes
Bit Error Code Description
7 Field Device Malfunction An internal hardware error or failure has been
detected by the HART field device.
6 Configuration Changed A write or set command has been executed by
the HART field device.
5 Cold Start Power has been removed and reapplied,
resulting in the reinstallation of the setup
information. The first HART command to
recognize this condition automatically resets
this flag. This flag may also be set following a
master reset or self test.
4 More Status Available More status information is available and can be
read using command #48. Read additional status
information.
3 Primary Variable Analog
Output Fixed The analog and digital outputs for the primary
variable are held at their requested value. They
will not respond to the applied process.
2 Primary Variable Analog
Output Saturated The analog and digital outputs for the primary
variables are beyond their limits and no longer
represent the true applied process.
1 Nonprimary Variable Out of
Limits The process applied to a sensor, other than that
of the primary variable, is beyond the operating
limits of the device. To identify the variable, use
command #48, read additional status
information.
0 Primary Variable Out of
Limits The process applied to the sensor for the
primary variable is beyond the operating limits
of the device.
