Tab 'KNX - General'Permalink

Object: KNX

The tab in the configurator of the KNX editor shows an overview of all communication objects. The I/Os of the communication objects are applied automatically to the I/O mapping.

Entries can be edited directly in the table or in the “Communication object” dialog. Existing entries can be copied via copy&paste. The next free channel number is used automatically in this case.
