Labview 8.20 - "TDM streaming versus Binary Files"

[chrishassan]

Hello Herbert,

Please excuse me for invading your conversation here, but it appears that you are a TDM expert which is exactly what I need at the moment...

I am using LabVIEW 8.0 which means no TDMS, therefore, I am trying to use TDM to stream 15 minutes of 16 channels x 10000S/s of  acquired data to disk.  However, during the acquisition, my WindowsXp page file eventually maxes out and my program hangs.

I thought I could get around this by closing the TDM file that I am writing to after every 20 or so readings and then re-opening it to continue writing, but the page file does not "shrink to normal size" upon closing the TDM file.

1. Does 8.20 and TDMS exhibit the same behavior? (Although upgrading to 8.20 is probably not an option).

2. Do you know a way around this problem with LV8.0 and TDM?

Thanks for your time,

Chris

Herbert,

Please disregard my request for information about "flushing" TDM streams in LV8.0.  After doing a little digging, I found an update package that has LV8.20, and now I can use TDMS.

Thanks,

Chris
