Members

Member name	Value	Description
Unspecified	0	No feature is specified.
WindowsSecurity	1	The PIServer supports windows security through PIIdentity and PIIdentityMapping objects.
BulkDataAccess	2	The PIServer supports retrieving Data in bulk. The supported bulk Data methods include: RecordedValues(AFTimeRange, AFBoundaryType, String, Boolean, PIPagingConfiguration, Int32) RecordedValuesByCount(AFTime, Int32, Boolean, AFBoundaryType, String, Boolean, PIPagingConfiguration) InterpolatedValues(AFTimeRange, AFTimeSpan, String, Boolean, PIPagingConfiguration) InterpolatedValuesByCount(AFTimeRange, Int32, String, Boolean, PIPagingConfiguration) InterpolatedValuesAtTimes(IListAFTime, String, Boolean, PIPagingConfiguration) PlotValues(AFTimeRange, Int32, PIPagingConfiguration)
BulkSummary	3	The PIServer supports retrieving summary data in bulk. The supported bulk Data methods include: Summary(AFTimeRange, AFSummaryTypes, AFCalculationBasis, AFTimestampCalculation, PIPagingConfiguration) Summaries(AFTimeRange, AFTimeSpan, AFSummaryTypes, AFCalculationBasis, AFTimestampCalculation, PIPagingConfiguration) FilteredSummaries(AFTimeRange, AFTimeSpan, String, AFSummaryTypes, AFCalculationBasis, AFSampleType, AFTimeSpan, AFTimestampCalculation, PIPagingConfiguration) Summaries(IListAFTimeIntervalDefinition, Boolean, AFSummaryTypes, AFCalculationBasis, AFTimestampCalculation, PIPagingConfiguration) FilteredSummaries(IListAFTimeIntervalDefinition, Boolean, String, AFSummaryTypes, AFCalculationBasis, AFSampleType, AFTimeSpan, AFTimestampCalculation, PIPagingConfiguration)
FutureData	4	The PIServer supports data in the future through future PIPoint.
TimeSeriesDataPipe	5	The PIServer supports signing up for data update through TimeSeries.
DeleteRange	6	The PIServer supports removing time series data within an AFTimeRange. For the case of connection to a PICollective, this feature is supported if all collective members support them. The supported methods include: ReplaceValues(AFTimeRange, IListAFValue, AFBufferOption) ReplaceValuesAsync(AFTimeRange, IListAFValue, AFBufferOption, CancellationToken)
BulkRecordedValuesAtTimes	7	The PIServer supports retrieving recorded values by time in bulk. The supported bulk Data methods include: RecordedValuesAtTimes(IListAFTime, AFRetrievalMode, PIPagingConfiguration)
OIDCSecurity	8	The PIServer supports OpenID Connect security through tokens and PIIdentityMapping objects.

Remarks

The supported features can be checked for a PIServer by calling its Supports(PIServerFeature) method. Supported features are determined by the version of the PI Data Archive and what the server reports that it supports.
