2.3.1
Individual Address
For line coupler functionality in a KNX network MECps640 has to use the correct Individual
Address of a line coupler (x.y.0, 1≤ x & y ≤15). In ETS up to 225 addresses can be defined
(from 1.1.0 to 15.15.0).
For area coupler functionality in a KNX network MECps640 has to use the correct Individual
Address of an area coupler (x.0.0, 1≤ x ≤15). In ETS up to 15 areas can be defined.
If MECps640 is used in a KNX system for both purposes, it is necessary to ensure that the
MECps640 used as a line coupler has a line coupler address assigned from a free addressing
area. Following figure illustrates the correct line coupler topology.

Example: If an area coupler with address 1.0.0 already exists on the backbone no line coupler
with address 1.x.0, 1≤ x ≤15 can be added here. Even if no line coupler with address 1.1.0
exists on the subline of the 1.0.0 area coupler. Vice versa, if a line coupler with address 1.1.0
already exists in the installation no area coupler with address 1.0.0 can be added.
