Diagnostic addresses with direct data exchange
You assign a diagnostic address to the receiving station when directly exchanging
data:
During configuration you define in
the receiver a diagnostic address
that is allocated to the sender.
The receiver receives information
on the status of the the sender or
on a bus interruption via this
diagnostic address.
