Recalculation 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 libraries. 

EAST ROCHESTER, New York, August 15, 2011 - Exele Information Systems, an industry leader in manufacturing application and process control software,  has announced major enhancements to OPCcalc® and EDICTvb.Net,  a pair of process calculation software products for OPC (PLCs, SCADA, Control Systems, Historians) and OSIsoft PI.  The version 3.7 release adds the ability to recalculate equations. 

Under 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 lab values).

“Recalculation 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.”
