Vaillant VR71 eBus and binding

I have a Vaillant system that is controlled by a VR71 and sensoNet. I tried to connect with eBus binding to the port 12480 of the sensoNet (with port scanner was opened) and my eBus bridge goes to online.

Somebody knows what have I to add next? I cannot find the Vr71 in the things list.
Thanks for any suggestions
