2.5. KNX Topology
Via a line/area coupler up to 15 lines can be connected to a main line called an area. It is possible to
have up to 64 bus devices on one line. With use of line repeaters, a line can theoretically be extended
to 255 bus devices. This means up to four line segments form a single KNX TP line. But it is common
practice on exceeding 64 bus devices to insert a new line instead of extending the originating one.
The free tree structure of the KNX topology prevents problems caused by circling telegrams and heavy
bus load. To maintain this condition, interconnection between lines or line segments is strictly
forbidden.
