Functional Description

This example uses two methods to retrieve the last trace written to your Citadel Database, or the database of your choice. The first is by using NI Hypertrend to graph the data being sent in to the database, or the last logged trace. This graph does not need a while loop to run continuously. The second method retrieves the trace information for the desired time you specify. In this particular setup, it retrieves the last second of trace data so that a user can identify the final inputs to their database

Caveats and Additional Notes

LabVIEW DSC module is needed to use this VI. As well, if you undeploy the shared variable that was logging the data or turn off the computer for a period of time, then no trace data will be found. This is due to the database having a NaN written into the trace at the current timestamp. So looking back one second in time will not prove useful
