with the SFC13 and in TwinCAT it is read with the ADSREAD FB.
The maximum length of the diagnostic data can be altered through
User_Prm_Data (byte 11). If there is more diagnostic data available than
can be sent, this is itself indicated in the diagnostic data.
DPV1 format
If the DPV1 diagnostic format is set in User_Prm_Data (byte 2, bit 3 = 1),
the diagnostic data appears as follows (this is only supported by the
BK3x10 / BK3500 / LC3100):
Byte no.; bit no.
Description
Byte 0
Bit 0: slave does not answer (is set internally by the DP master)
Bit 1: slave is starting up (parameterisation and configuration are being evaluated)
Bit 2: configuration error
Bit 3: Ext_Diag_Data available (from byte 6)
Bit 4: function not supported
Bit 5: incorrect answer from slave (is set internally by the DP master)
Bit 6: parameterisation error
Bit 7: slave is exchanging data with another master (is set internally by the DP master)
Byte 1
Bit 0: slave must be parameterised again
Bit 1: slave has static diagnostics
Bit 2: 1
Bit 3: DP watchdog is active
Bit 4: slave is in freeze mode
Bit 5: slave is in sync mode
Bit 6: reserved
Bit 7: slave is deactivated (is set internally by the DP master)
Byte 2
Bit 0-6:
reserved
Bit 7: too much Ext_Diag_Data
Byte 3
