Best way to start, for using OpenHab2 and Beckhoff CX9020

Hey there,

i just saw the new openhab2 HomeAutomation Framework. Looks perrty good and now i want to use this in my home automation szenario. I’m already using the Beckhoff system.

But to start with OpenHab, i have a little question at first:
is there any ADS-Protocol-speaking Binding, or do i have to start with the ModBus-One? For sure, there are at least many ways to connect to the Beckhoff Control, like http-bindings.

Perhabps, someone of you could help me out, while trying to figure out the best way to start.

Thanks a lot,
