Compact daq (Error for long time measurement)

[katayama]

I have a trouble when I use the NI9215 (analog input module of the compact DAQ).

When it was kept sampling for more than 20 seconds, I got a error message from labview.

For example, it is operated at the sampling frequency, 10 kHz, and try to get more than 200 kS, namely it takes 20 s, error messagy popped up in the labview program. In the labview program, I use a DAQ assistant, which is connected to DAQ mx read.

Please give me some advice. Thanks.

Post the message will be helpful, this can help determine if it is a buffer overflow, timeout, improper property memory leak...

Is it possible that you forgot to change the default timeout on your DAQmx read vi?

When I started using the DAQmx I got those messages, then I found out that the vis have a timeout input, that by defualt is set to 10 s, if you don't change it you'll get those messages.

Thanks for a comment. I changed the default time out of the DAQ assistant, but I did not try changing it for DAXmx read.vi.

I will try it.
