Extended DiagData
A distinction is made in the Extended DiagData between identification diagnosis, channel diagnosis and manufacturer-specific diagnosis. The first byte indicates the type of the diagnosis and the length of the associated data. Several diagnostic types can also follow one another in the Extended DiagData.
Header Byte
Bit | Meaning |
|---|---|
0-5 | Length of the associated diagnostic data, including header byte |
6-7 | 0 = manufacturer-specific diagnosis (DPV1 is not supported) or DPV1 diagnosis (DPV1 is supported (DPV1_Enable = 1) in associated GSD file) |
1 = Module diagnosis | |
2 = Channel diagnosis |
Manufacturer-specific diagnosis
The structure of the manufacturer-specific diagnosis may be found in the documentation for the DP slave.
DPV1 Diagnosis
In the case of DP slaves that also support DPV1, the DPV1 diagnosis, in which a distinction is made between status messages and alarms, is sent instead of the manufacturer-specific diagnosis.
