When opening an old .ccl file in comfigurator the kepads or UCM do not appear - so they have to be added.
The number of keypads form the original file still existis in the modules and settings.
In Comfigurator 3, the Modules Tab shows UCMs, Keypads, Door stations etc but this feature was not in Comfigurator 2 so you will have to manually add them
BUT
You DO have a record of them in settings
So why not add the no of keypads as per the number described in configuration modules and settings
Same with doorphone ?
The old ccl file had numbers or keypads, UCMs etc but if you notice, the new comfigurator Modules Tab has Types of UCMs (eg GSM, general, KNX, Cbus, etc) as well as Types of Keypads (KP03, KP04, KP06, KT03) so the information from the cclx file is not enough to make it into the new Modules tab
It is much more practical to scan for the modules or add it manually into the modules tab
