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variables are beyond their limits and no longer 
represent the true applied process.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.
