Retrieval Modes

The following retrieval modes can be set:

Retrieval mode



Raw data, as it was logged, for the specified start and end date/time.


An aggregate consisting of calculated data grouped by time interval. You must supply the time interval and type of calculation (function) to apply to the data.

Current Value

The current data value.

NOTE: The Current Value retrieval mode ignores the start and end times. If you want to return the most current value within the start and end time range (that is, the value closest to the end time), select the "raw" retrieval mode, set the Max. Rows at 1, and choose a Sort Order of Descending.
