About two VIs

[luiart]

Hi,I'm luiart.
I'd like to know something abour acquisition with more than one VI.
I've two VIs:when I run both of them the acquisition is much slower than they run alone.
What is it up to and how can I solve this problem?
Thanks luiart.

Luiart;

You are probably seeing that behavior because your aquisition task is probably a synchronous type. If you are running a synchronous acquisition, all the CPU time will be sucked up by the acquisition.
You need to set up a Asynchronous DAQ type which can be found at Search Examples->I/O Insterfaces->Data Acquisition->Analog Input->DAQ Occurrences.
Hope this helps.
