As soon as the AS-i configuration error is cleared, the OB82 is invoked again. In
turn the diagnostic address of the VBG-PB-K30-D-S, here 1022, is entered as a
parameter and the event is declared as an outgoing event.
Entry of the error messages in the diagnostic buffer of the CPU and invoking of
the OB82 is a consequence of the set ExtDiag flag for an error in the AS-i 3.0
PROFIBUS Gateway in Stainless Steel.
This can be prevented by turning off the ExtDiag flag in the PROFIBUS parame-
ters of the VBG-PB-K30-D-S.
The errors can be responded to by the controller by querying the AS-i flag in the
input data. This means a configuration error is reported twice in a standard case:
Once via the AS-i flag Config Error and once via the ExtDiag flag in the PROFI-
BUS telegram.
