VISA Resource Name alias to integer

I need to "convert" a VISA Resource Name alias an integer that will passed to a Call Function Node input parameter.

For example, COM1 will result in 1.

 

So far I have wired the VISA Resource Name to Format Into String then wire that string into Scan From String.

Is there an easier way.

You can use VISA property node to get this information (and other informations, like "is it serial port?").

Hi, is there a way to do this in the other direction? I will use Labview for a plugin in a other program. For this I need for input only a integer variable, e.g. the number of the COM Port. Is it possible to convert this then in a Visa Ressource name?

Simple like this:

(You can wire strings into VISA resource inputs…)

Hi Gerd, thank you for the very (very) fast response:-)

I found in the last minute my own solution.

So both works. Thank you again.

I do something similar to GerdW.

NOTE: That Set Termination Settings is my own VI, so don't go looking for it in the palettes.
