The diagnostic messages that are created by the Profibus slave have,
depending on the parameterization, a length of 58Byte.
As soon as the Profibus slave sends a diagnostic to the master, the max.
of 58Byte diagnostic data are prepended by 6Byte norm diagnostic data:
Byte 0 ... Byte 5 Norm diagnostic data
Byte 6 ... 10 Identifier related diagnostic *
x ... x+11 Module state*
7...13
⋅
(x ... x+2)
Channel related diagnostic*
x ... x+19 Alarm* Internal stored diagnostic
*)
Can be enabled or disabled via parameterization
Due to the restrictions there are the following diagnostic data for the
IM 253-1DP31 - ECO:
Byte 0 ... Byte 5 Normdiagnose-Daten
Byte 6 ... 7 Kennungsbezogene Diagnose*
x ... x+5 Modulstatus*
10...13
⋅
(x ... x+2)
Kanalbezogene Diagnose*
x ... x+19 Alarm* Internal stored diagnostic
*)
Can be enabled or disabled via parameterization
At the transfer of a diagnostic to the master the slave
norm diagnostic data
are prepended to the diagnostic bytes. More detailed information to the
structure of the slave
norm diagnostic data
is to find in the norm papers of
the Profibus User Organization.
The slave
norm diagnostic data
have the following structure:
Byte Bit 7 ... Bit 0
0 Bit 0: Bit is always at 0
Bit 1: DP slave is not yet ready to exchange data
Bit 2: Configuration data does not correspond
actual
configuration
Bit 3: External diagnostic available
Bit 4: Request function is not supported by the DP slave
Bit 5: Bit is always at 0
Bit 6: Wrong parameterization
Bit 7: Bit is always at 0
1 Bit 0: New parameters have to be assigned to the DP slave
Bit 1: Statistic Diagnostic
Bit 2: Bit is always at 1
Bit 3: Response monitoring has been enabled
Bit 4: DP slave has received "FREEZE" control command
Bit 5: DP slave has received "SYNC" control command
Bit 6: reserved
Bit 7: Bit is always at 0
2 Bit 0 ... Bit 6: reserved
Bit 7: Diagnostic data overflow
3 Master address after Parameterizing
FFh: Slave has not been parameterized by DP master
4 Ident number High Byte
5 Ident number Low Byte
