Hello,

I'm trying to design the VI enclosed to acquire data with the NI 6211 card. I use LabVIEW 8.5 (2007) and an error occurs after the "Read property node" (number -200077).

Does anyone can help me please? Is it a matter of LabVIEW version ?

Can I create a similar program with LabVIEW 8.5 ?

Thanks.

Hello.

Could you explain what you want exactly to do?Why changing the read position 2 times in a loop?

Which case of the sequence generates the error?Does it always happen?

Best regards

Hello,

Actually, I want to acquire analog voltage with USB 6211. I tried to use this example https://decibel.ni.com/content/docs/DOC-2431

I sent an analog sine voltage to check the data acquisition and I get this behavior (attachement). The frequency was set at 75Hz and the sample rate at 1000 S/s.

Also, when I'm usign a test pannel with MAX, the data acquisition is well.

Thanks for your answer.

Hello.

The VI you used really implements good development practices.

How did you connect the analog output to the input?is it in differential or single ended mode?

The default mode is differential for this VI.Could you check if you connections correspond to this?

Best regards
