I want to run a vi for 4 days and save 360,000,000 samples in a file

Hi

I want to run a vi for 4 days and save samples to a file.

I use the Ni EX save to file.vi example provided by LabView and change the Trigger mode to "immidiate ref trigger" as I am measuring a DC voltage.

The application runs correctly when min record length is 2048 however when I change the min record length to 2,000,000 I receive the following error message and nothing get saved:

Error occurred at:  niScope Multi Fetch.vi
<err>Driver Status:  (Hex 0xBFFA2003)
Maximum time exceeded before the operation completed.

Possibly no trigger received. Buffers done: 0, Points done: 0.000000.

I appreciate if you help me in this regard,

Maryam

Maryam,

Have you tried increasing the timeout?  What is the exact name of the vi that you are using. Also, what hardware are you using?  What driver versions do you have installed?  Actually, the more information you could give us, the better.  Thanks and have a great day!

Regards,
