Well, that's the big question ...
Most of the binds/rollers motors, like tubular motors, have no
integrated electronics, they just have a wire for the neutral, a
second wire to make the motor run in one direction, a third wire to
make it run in the other direction (never power those two wires at the
same time, of course) and the two end-of-course switches.
In the case of garage door motors, it is more complex because there
any many different ways to open a door ; so it is impossible to answer
the question because it is linked to the way the motor and the
surrounding electronics have been built.
If you can buy a motor that has separate 'go up' and 'go down' inputs,
eventually completed with the traditional "one button - up/down"
remote control (or input), it is probably the easiest way to connect
everything to EIB.
If you don't find such a motor that fits your door, and you end up
buying one without the "magical 2 extra inputs", then you'll probably
need to open the top cover of the motor (and its electronic module) to
find inside how to "build" the 2 missing inputs. The hardware part
will most probably not be more complicated that adding 2 or 3 small
relays and maybe a few diodes, but even that may be far too
complicated for you if you're not experianced into such a work ... and
in any way it will definitely void the warranty on your motor.
So, except if you are a trained electrician/electronician and decide
to work with a used motor, the vendor of the new motor will be THE guy
you need to discuss with at this point, in order to get a motor with
the extra inputs.
By the way, it doesn't necessarily need to be 230V AC inputs, EIB
blind/roller modules also exist for 24V DC as far as I know, and with
a pair of relays you can make it work for any voltage and without any
modification to the motor in this case :-).
