How to read one number in an new coded Vi file using an already exited Vi file

[ZhenCo]

Hi everyone,

I have a new coded program and I need to connect it to a hardware and drive the card. But it dosen't work. I contacted the manufacturer and he told me what is missing in my scheme is some handshake with the status of the acquisisition. And I need a already existed .Vi file to read the number of sweeps to get information how far the acquisisition is completed. So my question is how to execute this? How to let the already existed .Vi file to connect to my coded .Vi file to fulfill the "reading" function? I really appreciate for helping. I am totally a fresh man.

Thanks a lot

Best regards,

Jane

If it is a VI, you just call it in your own VI as a subVI.

Thank you so much for your quickly reply. For calling of an VI as a subvi in my vi file, just using "select a Vi" in the Block Window of my Vi file, is that correct?

Thanks.

That's one way.  You can also just drag the VI from your project or even Windows Explorer to your block diagram.
