Overview:
This example reads an historical trace and extrapolates the data to the start and end time interval. When the maximum number of points per trace is set, DSC's Read Historical Trace.vi ignores extrapolation thus returning missing start and end points (in some cases only 1 data point). This VI always extrapolates and adjusts for the last recorded value in the citadel database in order to always extrapolate between the time interval specified.
Software & Toolkits:
LabVIEW 2010
Datalogging and Supervisory Control (DSC) Module 2010

This is an awesome work-around to helping an application meet the expected extrapolation results
Very inspiring work.
I working on an .exe VI that traces several Instruments and has the possibility to extract several traces of one library at once to a spreadsheet.
Like you do with MAX but from a Runtime only Computer.
This example is very helpful!
Thanks for sharing.
