Is there a way to browse the channels of Veristand using a LabVIEW VI?

[James9]

I'm able to stream data from Veristand to a LabVIEW program but it requires me to set a specific path on LabVIEW. I was wondering if there was a way to scan & list all of the Veristand channel paths so I don't need to specify them. I checked out the TreeBrowserWF but I'm not quite sure how it work, and that I have the issue of missing files when loading the handful of usage available.

Here is something I built to view channels from VS from Labview.  If you look through the shipping examples I think it has how to use TreeBrowserWF.  The Subvis should all be in the vi.lib.

I seem to be missing the "Create Custom Channel Alias Filter.vi" as it was not found.

You don't need the filter vi, this was just so I could hide stuff from the user.  Here it is anyway.

Hello,

with "Create Custom Channel Alias Filter.vi" I see also the Custom Devices Channels.

I am not able to see ONLY the Aliases Channels.

Somebody can help me?

You will have to play around with the Custom Filter to only display the Alias channels.  Here is a discussion I had about filters.

I saw that discussion and I set the input of "Create Custom Channel Alias Filter.vi" in the same way of the post: Allow Alias==TRUE, Writable==FALSE and VISIBLE==TRUE. But I am not able to hide the CD channels. I tried also other inputs combination without success result.

This is where trial and error is going to come in since there is no documentation.  You might be able to contact NI directly if you have a support contract.  I would dig into the ITeaverseNode Filter Constructors in the Create Custom Chanel Alias Filter vi (TravNdMatchChannelFilter, TravNdAliasDependentFilter, etc) Copy one and right click and see what other constructors you could use to get the nodes you want and hide them.  I saw TravNdMatchNodeNameFilter that might work.  Please post if the code if you are successful and good luck.
