VISA resource connected

Solved!
Go to solution

Hi,

 

I would like to check if a VISA ressource is already in use.

 

This seems to be indicated by this symbol in the VISA resource name control:

THBU_0-1575901125586.png

 

Where can I find documentation about the meaning of this symbol? 

Is it possible to read the status of the connection programmatically in code?

 

Thank you!

 

Thomas

Hi Thomas,

 

You can read open VISA sessions using this code:

Thank you, Vilius

 

If someone else should look for this VI, it is located in Program Files (x86)\National Instruments\LabVIEW 2019\vi.lib\Utility\visa.llb
