Integral retrieval

Integral retrieval calculates the values at retrieval cycle boundaries by integrating the graph described by the points stored for the tag. Therefore, it works much like average retrieval, but it additionally applies a scaling factor. This retrieval mode is useful for calculating volume for a particular tag. For example, if one of your tags represents product flow in gallons per second, integral retrieval allows you to retrieve the total product flow in gallons during a certain time period.

Integral retrieval is a true cyclic mode. It returns one row for each tag in the query for each cycle. The number of cycles is based on the specified resolution or cycle count.

Integral retrieval only works with analog tags. For all other tags, normal cyclic results are returned.
