MaxMinutesForDeltaDiscrete

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

Syntax

aaHistClientTrend.MaxMinutesForDeltaDiscrete = integer;

Result = aaHistClientTrend.MaxMinutesForDeltaDiscrete;

Remarks

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

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

The default value is 15.
