Bit Error Code Description
7
Communications Error If set, the field device has detected a communications error. Bits 0  6 indicate the type of error.
6 Vertical Parity Error The parity of one or more of the bytes received by the HART field device is incorrect.
5 Overrun Error At least one byte of data in the receive buffer of the HART field device was overwritten before it
was read.
4 Framing Error The stop bit of one or more bytes received by the HART field device was not detected.
3 Longitudinal Parity Error The longitudinal parity calculated by the HART field device does not match the longitudinal parity
byte at the end of the packet.
2 Reserved Set to 0.
1 Buffer Overflow The packet is too long for the receive buffer of the HART field device.
0 Undefined Not defined at this time.

All
➀
No commandspecific errors No errors were found in verifying the parameters for this command.
2
All
➀
Invalid Selection The code or index was not allowed in this command or for this field device.
5
All
➀
Too Few Data Bytes Received The message syntax was proper but the number of bytes contained in the message
was less than required to execute the command.
6
All
➀
TransmitterSpecific
Command Error
An error occurred in a HART command for which a CommandSpecific Response
Code is not defined. Further information on this response code is available in each
TransmitterSpecific document.
7
All
➀
In Write Protect Mode The field device is Write Protected and cannot accept this write command.
8
All
➀
Warning: Update Failure The realtime data returned from the field device has not changed since the last time
it was read.
9 35 Lower Range Value too High The Lower Range Value was above the Upper Sensor Limit.
43 Applied Process too High The process applied to the field device was too high.
10 35 Applied Process too Low The process applied to the field device was too low.
43 Lower Range Value too Low The Lower Range Value was below the Lower Sensor Limit.
11
All
➀
Upper Range Value too High The Upper Range Value was above the Upper Sensor Limit.
12
All
➀
Upper Range Value too Low The Upper Range Value was below the Lower Sensor Limit.
13
All
➀
Upper and Lower Range
Values Out of Limits
Both the Upper and Lower Range Values are beyond their limits.
14
All
➀
Span too Small The Span, as determined from the Upper and Lower Range Values, was below the
Minimum Span.
16
All
➀
Access Restricted The command was rejected due to a condition within the Field Device which would
prevent proper execution.
32
All
➀
Busy The device is performing a function that cannot be interrupted by this command.
64
All
➀
Command not implemented The command was not defined for this device.
