KNX Configuration Modes Explained
KNX Protocol - 10-Minute Course
The KNX Standard includes different Configuration Modes:
S-Mode (System Mode):
- S-Mode uses the standard frame format. It needs active Network Management (as performed by ETS) with Broadcast and Individual Addressing.
 
Controller Mode:
- It uses Group communication with the standard frame format. It needs active Network Management (as performed by ETS) with Broadcast and Individual Addressing.
 
Push button mode:
- For configuration, PB mode relies only on active management from one device directly by another. It uses group addressing with the standard frame, with structured binding.
 
Logical Tag Extended mode:
- LTE defines extended frames for its "native"  run-time communication, with
    tagged binding on Interface Object properties.
