Diagnostic Update
Delay
The maximum number of extra diagnosis cycles that the master waits
to obtain from a slave the release for a DATA_EXCHANGE. If the
Diagnostic Update Delay is set to 0, the master waits for one
diagnosis cycle before reporting an error. If the Diagnostic Update
Delay is set to 15, the master waits for 16 diagnosis cycles before
reporting an error. The master waits for one diagnosis cycle more
than the value of the Diagnostic Update Delay.
Some newer slave devices require more time for the consistency
testing for the processing of the SET_PRM parameterizing telegrams.
Therefore, a simple diagnosis cycle may be insufficient until the
participant can inform the Master of the release for the
DATA_EXCHANGE.
Valid range: 0 through 15.
