Error in NIScope read

[alex.]

The program works fine until yesterday, but today it seems not stable, sometimes gave error as the attached screen.

I tried the NIscope front panel, it(5133) works fine.

Any suggestion?

Thanks, but I am only having one device and just simple data polling as attahced.

It may caused by not close the session properly. As attached, there are many sessions, some cannot close even I tried to make another simple program.

But I tried to start the system still not work. Unable to open the sample there since the version is too old.

May you give any suggestion, thanks.

You are right at this point. Try closing the session. If not possible try closing LabVIEW and re-launch LabVIEW. Quick try and post back

I restart the PC, unplug and plug the 5133, but still get seem error.

This time even use niscope or Max test cannot run any more.

After self test 2 times, it now works with NIscope front panel only.

Does I missing something, such as NIscope initiate acqusition.

Are you opening up multiple session and not closing it properly?

[alex.]

I just open one session and close it in the end in the attached DAQ2.vi

Now seems know the error, when I open the signal generator and when there is signal coming in, the program works ok and no errrors occur.

But I am still not sure how does it happen and how to change my program.

Any suggestion?

Are you saying that the program now works and that when it wasn't working, you did not have a signal applied? If that's the case, then the error message is normal. Without a trigger event, there is no waveform captured so you are supposed to get a timeout.
