Where can i find the BACnet-Binding .cfg file

I have added the .jar to the addons folder but i can´t find the .cfg.

If it is not created automatically just create it manually …

Where?
Name of of the .cfg file?

Haven’t found the docs yet?

Take a look here:

http://docs.openhab.org/tutorials/migration.html#configure-add-ons

It looks like there is an updated version of the binding, so you should look at those threads (found through the search button on the top right of this forum):

It should be located in conf/services/bacnet.cfg as far I remember.
