Topology and structures in KNX-Programming
The KNX bus is hierarchically structured. The smallest installation unit is the line.
Up to 64 bus participants can be connected to each line. A line can consist of a maximum of 4 line segments.
Up to 15 lines can be combined into one area via line couplers.
What happens if more than
64 participants are on a line
If more than 64 participants are connected to one line or the line lengths are exceeded, it is possible to connect more participants to another line via line amplifiers or to allow longer line routes.CONTACT
Physical address – the house number
of the KNX participants
The physical address uniquely identifies all bus participants. The physical address is
only displayed in three digits and may occur only once in the project.
Communication takes place – communication objects
The communication object determines which data is sent on the bus and how big this data is. The smallest data type is the bit, and I’m not talking about the German beer.CONTACT
