1
1: The DP/P-bus link is not ready to
exchange data
Wait until start-up procedure is complete
2 1: The engineering data transmitted by
the master to the DP/P-bus link does

3 1: External diagnosis available
(common diagnostic display)
Evaluate diagnosis. The bit will be reset as
soon as all errors have been cleared.
4 1: The DP/P-bus link does not support

5 1: The master cannot interpret the re-
sponse from the DP/P-bus link.
Check the bus structure.
6 1: The DP slave type does not match
