Check this box to enable DPV1 settings for the selected PROFIBUS device. The device's GSD
file determines which settings are editable and which are read-only.
Clear this check box to disable DPV1 settings. The values of all parameters are retained
until the DPV1 settings are enabled again for the selected device.
The maximum length in bytes of the DPV1 telegrams. The slave adapts its buffer size for
the respective data count.
Valid range: 4 through n bytes, where n is the value specified in the GS? file.
The maximum length in bytes of the DPV1-Alarm telegrams.
Valid range: 4 through n, where n is calculated by the following formulas
m = Max_Diag_Data_Len - 6
n = Max(Min(m,64),4)
Max_Diag_Data_Len is a value specified in the GS? file. If m is greater than 64, n is set to
64. If m is less than 4, then n is set to 4. Otherwise, n is set to m.
If n is set to 4, the only valid Maximum Alarm PDU Length is 4.
Default: The value n calculated by the above formulas.
The maximum number of extra diagnosis cycles that the master waits to obtain from a
slave the release for a DATA_EXCHANGE. If the Diagnostic Update Delay is set to 0, the
master waits for one diagnosis cycle before reporting an error. If the Diagnostic Update
Delay is set to 15, the master waits for 16 diagnosis cycles before reporting an error. The
master waits for one diagnosis cycle more than the value of the Diagnostic Update Delay.
Some newer slave devices require more time for the consistency testing for the processing
of the SET_PRM parameterizing telegrams. Therefore a simple diagnosis cycle may be
insufficient until the participant can inform the Master of the release for the
DATA_EXCHANGE.
Valid range: 0 through 15.
The maximum number of possible active alarms.
Choices:
1 alarm of each type
2, 4, 8, 12, 16, 24 or 32 alarms in total
The service access point (SAP) through which the master quits alarms.
Choices:
Master Alarmacknowledge SAP51: Master quits alarms via SAP51.
Master Alarmacknowledge SAP50: Master quits alarms via SAP50.
The DPV1 data types.
Choices:
Configuration Data of EN 50170
Configuration Data of DPV1
