KNX network,
three-level structure

A full KNX network is structured on three levels. It consists of:

  • Backbone (area line): 0 🡪 Area 0 (backbone)

  • Main lines: 1...15 🡪 Areas 1…15

  • Lines: 1.1...15.15

Note

The arrangement of the bus devices in the 3-level KNX network structure, with the Synco bus devices factory set with Area/Line address 0.2 corresponds to the gray shaded area in the illustration above.

Area line 0

The area line is the backbone of the network. The subnetwork address (area line) is 0.0 (zero.zero). 15 area couplers (Ac) can be connected to the area line, in addition to bus devices (not shown), whose number is determined by subtracting the number of area couplers from 64.

Main lines

15 main lines can branch off from area line 0 by means of area couplers. The area couplers used to establish the main lines have physical addresses from 1.0.0 to 15.0.0. Each main line can accommodate 15 line couplers (Lc), in addition to bus devices (not shown) whose number is determined by subtracting the number of line couplers from 64.

Lines

15 lines can branch off from each main line via line coupler. The line couplers used to establish the lines from main line 1 have physical addresses from 1.1.0 to 1.15.0. Line couplers from main line 15 have physical addresses from 15.1.0 to 15.15.0.
