How to check number of elements available in RT FIFO?

Solved!
Go to solution

Hi,

 

    Without using READ FIFO function is there a way to check the number of elements in RT FIFO? I am looking a function like the get queue status function VI.

 

    Thanks a lot!

 

    Regards,

 

    Tom

I am having this exact question right now however the link to the document referenced does not give me access.  Is there a better link?

RT FIFO Read and Write functions have had a "# elements" output since LabVIEW 8.2.  You should be able to utilize that output to determine how many elements are left in the FIFO.  If you have a version of LabVIEW previous to LabVIEW 8.2, you can utilize the attached VI to determine how many elements are left.
