A standard KNX device that is fully programmed contains an Individual Address, an application, parameters and the Group Addresses.
True
True. After a successful complete download from ETS, a standard KNX device stores four things: its Individual Address (unique identifier on the topology), its application program (the firmware-level logic for its function), its parameter values (the configuration choices made in ETS), and the list of Group Addresses linked to its Group Objects (the communication side). Only with all four does the device participate correctly in the installation.
When troubleshooting a 'silent' device, check via ETS Device Info whether all four blocks are present — a missing Group Address table is a common reason a device 'looks programmed' but never reacts.
