Recovering data in history but not logged

Recommended Posts

Is there a way to recover the data from history that was not logged in a logging set?

I set up a counter that measured pulses over one minute intervals but failed to include the channel in a log set.

I saved the program 'with history' so when I open the program I can see the old data with about 125 minutes of counter data in the channel table and in the graph, but I can't seem to figure out how to extract it into a data file.

I have tried re-running the program with the counter data channel as part of a logging set and by exporting, but the history disappears and only new data shows in the log and export files.  

Any help would be appreciated.

You should be able to setup an export set to do it. Just make sure not to include [0] in your expressions.

If that doesn't work you can create a little script to write the data to a file using the lower level file. functions.  Is it just one channel?
