Using LM/Wiser "offline" (without KNX)

[mjaanes]

I am programmering ETS remotely at the office (i.e. not at site).
At the office, I do not have KNX setup.
I would like to setup the LM/Wiser also at the office prior to going out to the site.
In particular:
1) Importing objects (that's easy) and
2) Configuring the visualization (mostly "Touch Configurator").

I do have the physical device at the office.

Therefore: Can I "program" the LM/Wiser via IP only or must it be connected to a KNX line?

Thanks
