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 drive response returned the ASCII text Drive Reset Flt,
with each character reversed. The fault code for this example is 22.
