There is no "self test" VI in DAQmx. Your query seems to imply that you saw it in the past. Are you basing this on the self-test that exists in MAX?

You can build your own self test with loopback cables and a vi that generates signals and reads the signals from the loopback cable.  If this is what you want, we can provide more details.

hi,

thanks for your replay, i have already built loopback and tested i was wondering is there any vi available as it is available for other cards to check the self test operation of the card as in  Measurement and automation.

No self test vi's available that I am aware of.  That is why I suggested writing your own.  We do this all of the time.

There is no Self-Test VI or function in LabVIEW. You can try using the Reset Device function in LabVIEW which provides similar functionality as Self Test in MAX.

You find details in the following link.

If you wish to do a hardware level test of the I/Os, you will have to write your own code in LabVIEW as suggested earlier. 

Hope this helps.
