MaxMinutesForDeltaAnalog

The MaxMinutesForDeltaAnalog property is a read-write property that gets or sets the maximum minutes filter for analog tags for delta retrieval mode.

Syntax

aaHistClientTrend.MaxMinutesForDeltaAnalog = integer;

Result = aaHistClientTrend.MaxMinutesForDeltaAnalog;

Remarks

The aaHistClientTrend control only takes this property into account when retrieving data from AVEVA Historians with a version earlier than 9.0.

Delta retrieval is used for analog queries that have a time range that are within the setting of the MaxMinutesForDeltaAnalog property. If the query time range is longer, cyclic retrieval is used.

Remarks

The default value is 15.
