KNX
In conventional topologies, all line
and backbone couplers have usually
been designed as KNX couplers.
This topology is proven and widely
used. For the most part, the bus line
lengths are limited to one building.

KNX
In this modern topology, the back-
bone couplers are replaced with
N 146/02 IP routers.
Thanks to the use of standard net-
work components, the connection
for example of two building sections
is no longer limited to bus line
lengths.
Use of other media such as fiberoptic
cabling or WLAN is also possible for
the purpose of coupling distant buil-
dings and exchanging group address
telegrams.

KNX
In this innovative topology, all line
couplers are replaced with N 146/02
IP routers.
Backbone couplers are no longer
needed. This configuration allows
to connect every building floor by
Ethernet (LAN) and utilize existing
LAN networks.
Moreover, correct configuration
of the N 146/02 IP router enables
major projects to be commissioned
as smaller, individual subprojects in a
simpler, clearer manner.
It’s possible to exchange group
address telegrams despite the sepa-
ration into individual projects.
