Using Signals from Station Logic in Rapid Code?

Hello everyone.
I'm trying around with the profinet connection from a real s7-1500 to a virtual irc5 (using SmartComponent RSConnectGIO & DIO) and its working fine, BUT i wonder how to use the received signals from the station logic in rapid code.. can someone give me hints how to realize it?
For example, i want to use the output signals from GIO_xKoords and so on in my rapid program. Do i have to add any bindings or other connections?
Thanks for any
