DAQ 6008 need to be reconnected

[chipet]

  Hello,

  I have a problem while performing a voltage measurement using DAQ 6008 board;

I need to reconnect the board each time I want to measure otherwise if I run the program, stop it and after that run it again

I receive the error 200284 saying that some or all of the samples requested have not yet been acquired.

Any suggestion is welcomed.

 Thanks, Chipet

Hey Chipet,

I looked into this error code for a little bit and found this article that goes over the some common reasons for getting it:

I'm not sure where this is occuring in your VI, but I'd imagine it happens when you reads the samples. Adjusting the type of read you're doing (finite vs continous and the corresponding settings) could be helpful. Here is another article that goes through some of the more common DAQmx functions and when to use them:

Hope this helps,

Hey,

  Thanks for your answer. I forgot to add into the block diagram the clear task vi.
