get amount of wired physical channels?

[Andband]

Hi,

I need to create a subVI, and in that subVi it is important to know the amount of physical channels wired to the input of that subVI.

Is the only way to do that writing another 'string search and count'-subVI, which examines the 'physical channels'-wire? Something that searches for any ':' and ',' and which processes that information then.

Or is there a better way to do it?

Or has someone already written such a subVI, which counts the amount of wired channels?

Thank a lot

Andy

If you are asking about knowing how many channels are in a DAQmx physical channel? If so, just wire the physical channel to the DAQmx Unflatten Channel String. You'll get an array out. The array size function will give you the number of channels.

Yeah, that works perfect and was exactly that what I wanted 🙂

You guys really know your stuff!
