daqmx read/write error 50411

[Clecio]

Dear:

I'm finding an error in my application. When I read a waveform sine in my Analog Channel, appear the follow error:

Warning 50411 occurred at DAQmx Write (Analog Wfm 1Chan NSamp).vi

Possible reason(s):

There was no more data in the buffer when new data was being read. The data returned by the operation is stale as a result.

Can you help me to resolve this situation?

Thank you.

Clecio

Clecio,

If you are performing an analog input acquisition, please use the DAQmx Read instead of the DAQmx Write. Have you taken a look at the LabVIEW shipping examples for DAQmx (Help->Find Examples, then Hardware Input and Output->DAQmx)? These are a good place to start when developing new applications. Let us know if you have any more questions.

Hope this helps,
