For reading historical data. The aggregate type for history reading. Null for raw data.

Indicates if the x-value will be used as a number or as a string

Dataset StatusCode column

Specifies delay of the dataset update before we send it to session and UI.

Dataset X axis column

Dataset Y axis column

For monitoring realtime data. See DeadbandType.

For monitoring realtime data. The value if dead band is set to anything else than DeadbandType.None.

For reading dataset data.

For reading historical data. When the user choses to receive raw data, this value will override the session's buffer size specified by the viewer.

Indicates the Maximum percentage of bad data in a given interval above which would cause the StatusCode for the given interval for processed data request to be set to Bad. For values equal to or below this percentage the StatusCode would be Uncertain or Good. For details on which Aggregates use the PercentDataBad Variable, see the definition of each Aggregate. The default value is 0.

Indicates the minimum percentage of Good data in a given interval which would cause the StatusCode for the given interval for the processed data requests to be set to Good. For values below this percentage the StatusCode would be Uncertain or Bad. For details on which Aggregates use the PercentDataGood Variable, see OPC UA specification. The default value is 100.

The point name.

For reading historical data. When aggregate is set to raw data, this parametere specifies whether only modified data are to be read. Defaults to false.

Indicates how the server interpolates data when no boundary value exists (i.e. extrapolating into the future from the last known value). A value of False indicates that the server will use a SteppedExtrapolation format, and hold the last known value constant. A value of True indicates the server will project the value using SlopedInterpolation mode. The default value is False.

Indicates how the server treats data returned with a StatusCode severity Uncertain with respect to Aggregate calculations. A value of True indicates the server considers the severity equivalent to Bad, a value of False indicates the server considers the severity equivalent to Good. The default value is True.

This distinguishes the most fundamental properties of the session.

For monitoring realtime data. Whether to use a filter at all.

Use dataset StatusCode

When false, the user specifies the aggregate configuration, when true, lets the server decide.
