This byte is only prepended to the device related diagnostic data when this
is being transferred via Profibus.
Byte Bit 7 ... Bit 0
6 Bit 0 ... Bit 5: Length device related diagnostic data incl. Byte 6
Bit 6 ... Bit 7: permanently 0
Byte Bit 7 ... Bit 0
7 ... 29 Device related diagnostic data that can be stored internally by
the slave for analysis
As of revision level 6, all diagnostic data that is generated by the Profibus
slave is stored in a ring-buffer along with the time stamp. The ring-buffer
always contains the most recent 100 diagnostic messages.
You can analyze these messages by means of the "Slave Info Tool".
Since the standard diagnostic data (Byte 0 ... Byte 5) and the header
(Byte 6) are not stored, the data in Byte 0 ... Byte 23 corresponds to
Byte 7 ... Byte 30 that is transferred via Profibus.
The structure of the device related diagnostic data is as follows:
Byte Bit 7 ... Bit 0
0 Message
0Ah: DP parameter error
14h: DP configuration error length
15h: DP configuration error entry
1Eh: undervoltage/power failure
28h: V-bus parameterization error
29h: V-bus initialization error
2Ah: V-bus bus error
2Bh: V-bus delayed acknowledgment
32h: diagnostic alarm System 200
33h: process alarm System 200
3Ch: new DP address was defined
3Dh: slave status is ready (only internally)
3Eh: slave status is DataExchange (only internally)
1 Module no. or slot no.
1 ... 32: module no. slot no.
0: module no. slot no. not available
