This error is reported after your own programming
device is restarted in the case of long message
frames or when the partner is restarted. This
represents normal system start-up behavior. You do
not have to correct anything.
The error can also occur during operation as a
consequence of error statuses only recognized by
the partner.
Otherwise, you can assume an error on the part of
the partner device. The error may not occur in the
case of requests < 128 bytes.
Check for malfunction of the partner device, possibly
by using interface test device interconnected in the
data link.

Is the partner a slow device? This error is also often
displayed as a consequence of a previous error. For
example, procedure receive errors (event class 8)
can be displayed after a FETCH message frame
was sent. Reason: The response message frame
could not be received because of disturbances. The
monitoring time expires. This error also possibly
occurs if the partner is restarted before it could
respond to the last received FETCH message frame.
