Error -200279 in Analogue & Digital inputs

[Ano Ano]

Hello,

I have a NI USB-6001 and I am trying to run the attached simple vi and I get an error 200279. It supposed to just acquire an analogue & a digital signal. Can someone help please?

Thank you in advance

If you look at the explanation of the error code:

Quote

 

Attempted to read samples that are no longer available. The requested sample was previously available, but has since been overwritten.

Increasing the buffer size, reading the data more frequently, or specifying a fixed number of samples to read instead of reading all available samples might correct the problem.

 

You are trying to read one sample at a time when they are coming in at 1000 samples/sec. The buffer fills up and overflows. Try reading in 100 or more samples at a shot or slow your sampling rate to 10 samples/sec.
