Bits 6-7 Meaning
00B Type byte, with no consistency. Bits 0-5 contain the length of the data minus 1 (i.e. bits 0-5 =
000000B corresponds to a length of one byte, while bits 0-5 = 111111B corresponds to a length
of 64 bytes)
01B Type word, with no consistency. Bits 0-5 contain the length of the data minus 1 (i.e. bits 0-5 =
000000B corresponds to a length of one word, while bits 0-5 = 111111B corresponds to a length
of 64 words)
10B Type byte, with consistency. Bits 0-5 contain the length of the data minus 1 (i.e. bits 0-5 =
000000B corresponds to a length of one byte, while bits 0-5 = 111111B corresponds to a length
of 64 bytes)
11B Type word, with consistency. Bits 0-5 contain the length of the data minus 1 (i.e. bits 0-5 =
000000B corresponds to a length of one word, while bits 0-5 = 111111B corresponds to a length
of 64 words)
5.1.8.7 Diagnostic Data - DiagData
There follows a description of the DP diagnostic data
Offset Meaning
0x00.0 StationNonExistent: slave did not reply to the last telegram
0x00.1 StationNotReady: slave still processing the Set_Prm / Chk_Cfg telegram
0x00.2 CfgFault: slave signaling a configuration error
0x00.3 ExtDiag: extended DiagData available and valid
0x00.4 NotSupported: slave does not support a feature requested via Set_Prm or Global_Control
0x00.5 InvalidSlaveResponse: slave response not DP-compatible
0x00.6 PrmFault: slave reports a parameterization error
0x00.7 MasterLock: slave currently exchanging data with another master
0x01.0 PrmReq: Slave must be parameterized and configured again
0x01.1 StatDiag: slave signaling static diagnosis / DPV1 slave application not yet ready for data
exchange
0x01.2 PROFIBUS DP slave
0x01.3 WdOn: DP watchdog on
0x01.4 FreezeMode: DP slave in freeze mode
0x01.5 SyncMode: DP slave in sync mode
0x01.6 reserved
0x01.7 Deactivated: DP slave has been deactivated
0x02.0 reserved
0x02.1 reserved
0x02.2 reserved
0x02.3 reserved
0x02.4 reserved
0x02.5 reserved
0x02.6 reserved
0x02.7 ExtDiagOverflow: too much extended data present
0x03 MasterAdd: station address of master with which slave is exchanging data
0x04, 0x05 IdentNumber
from 0x06 Extended DiagData
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.
