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.
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.
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.
1.3.2 Network address
The network address for a full-scale KNX network consists of the area, line and
device address. It reflects the exact position of a bus device in the overall network
and is unique within the network.
Syntax: Area.Line.Device
Range 0
Range 1...15
Line. 1...15
Device 1...255
The Synco bus devices are factory-set with the KNX-defined area and line
address 0.2.
The "individual address" (a term from the KNX world) consists of the address
components area, line and device, and corresponds to the network address
already defined.
The "physical address" is another term for "individual address".
In KNX terms, a subnetwork is the same as a line. Hence, the subnetwork address
consists of the address components "area" and "line".
