PROFIBUS DP interface for IS1+
3.6 Diagnosis data
Depending on the PROFIBUS diagnosis format supported by the automation system IS1+ is able to transmit
diagnosis data according DPV0 or DPV1 specification. Selection is done by use of different GSE files:

The occurrence of diagnosis changes is registered to the class 1 master by the IS1+ field station in the cyclic
data exchange. The class 1 master then demands the diagnosis data from the IS1+ field station in an acyclic
telegram.
In addition to the 6 bytes of standard information complying with the DP standard, the IS1+ field station can
supply identifier-related diagnosis data, CPU-, module- redundancy and IO-Module status and channel-related
diagnosis data.
Diagnosis data can be displayed in a diagnosis user interface of the master configuration software and can be
evaluated via the user program in the automation system.
If there are
no alarms
in a field station, then only the 6 bytes of standard information (byte 0 to byte 5) are
transmitted in DPV0. Only if one or more alarms are present, the additional information (starting from byte 6)
is transmitted. This has to be considered at the evaluation of diagnosis data in the AS.
