PXIe List of Available Signals

[Silverfang-]

Hello everyone,

So I have a PXIe chassis and a bunch of PXIe 4300 AI cards. The test setup is regularly changed which means at any point the chassis could have any number of slots filled with these AI cards.

I want to write a program for acquisition such that the VI recognizes which slots are available and exclude the blank slots.

I realize that in the DAQmx Create Channel task, there is an input where you list the physical channels you want to acquire from, but how do I get the list of all available channels so I can feed it to this physical channel field?

I am relatively new with LabVIEW. Seeking help! Thanks in advance.

Hi Silverfang,

using the SystemConfiguration API you can determine all available devices…

Retrieve All DAQmx Physical Channels of a System Programmatically

Thanks. I tried both ways and the SystemConfig API method worked too but I think this is a simpler way to get all the active slots.
