evaluating reachability from PCSDK

Good Morning.
I’m trying to develop a standalone desktop app which would use the reachability of a robotstudio target.
I tried using robotstudio sdk developing some add-ins following the samples, but everyone implied an initial manual interaction with RobotStudio and couldn’t really communicate with extern apps.
So my take was that I need to use PCSDK. Is there a way to get the reachability of a target via SDK in a programmatic way?
Thanks for your time,
Stefano

I did this and got the reachability outside RS.
