Exele Releases Recalculation for OPCcalc and EDICTvb.Net
allows users to re-run one or more calculation libraries for a period
of time in the past without interruption to the real-time calculation

The version 3.7 release adds the ability to recalculate equations.
typical operation, process calculations run real-time, using current
input tag values to calculate current output tag values. If a historian
is available (OPC-had or OSIsoft PI), it stores the current output
values, making the results available to reports and trends. In some
instances, however, the calculated values that exist in the historian
should be replaced. The calculation logic may have changed or input
values to the calculation may have been modified (e.g. manual input or
allows the user to re-run one or more calculation libraries for a
period of time in the past” said Mike Fishman, Exele VP. “The
previously calculated data can be removed, and the calculations will
execute using the updated logic and/or inputs to repopulate the
historical calculation results. All of this occurs without
interruption to the real-time calculation libraries.”
