Message Operation

Fault Queue Entry Read Full reads the contents of the fault queue
specified in word 3 of the request. The response returns the fault text
which can be ASCII text. Every two characters of text are in reverse
order. Also, the 1336 FORCE drive returns a time stamp, indicating
the day and time the fault occurred.

If an error has occurred, word 1 of the response returns a negative
value.

Example

In this example, Fault Queue Entry number 3 was retrieved from a
1336 PLUS drive. The fault code for this example is 22, and the fault
name is Drive Reset Flt. The fault code (22) is word 11 (12th word) in
the decimal drive response. The fault name (Drive Reset Flt) is in the
ASCII drive response. Note that every other character is reversed.
