RSL, IsAbstract Interface, Start a Remote Subroutine

I would like, as was possible in the old versions,
that a master robot could subscribe to the programs
of another child robot, and the child robot would publish its programs,
so that the master could remotely call routines.
To call these sequences, in the TEACH menu, there was a button “Start a Remote Subroutine”
and the connection between the 2 components was done using the PnP -> Connect Abstract Interfaces "
If this is possible with Visual Components 4.1 or KUKASIM 3.1 then I would need an example.
Thanks to whoever can help me
