Required functionality is missing from the
data compression component.
The HART Application is unable to acquire
enough memory for data compression.
The system cannot open the DD.
An error is detected while uncompressing the
DD.
An unexpected value is returned from a
function call.
The checksum of the DD does not match with
that described in the DD header file. This
error may be corrected by connecting the 375
Field Communicator to the Easy Upgrade
Programming Utility and running a Refresh
operation.
The HART Application attempts to use a DD
to run in forward compatibility mode and finds
that the DD is prevented from running in
forward compatibility mode.
The DD for the connected device is not in the
375. If your System Card is licensed for Easy
Upgrade, you can add DDs to your 375 from
the Easy Upgrade Programming Utility.
The HART Application lets you ignore some
response code warning messages, such as
Update Failure, while communicating with a
device. The next time you communicate with
the device, this message will appear.
