6.2 Examples of device descriptions:
You should use a systematic legend when creating the description. It should contain the
following data in an abbreviated format:

Place of installation, e.g. DB1
Device type, number + number of channels (e.g. SDA 1f = 1-fold switch/dim actuator,
ShA 4f= 4-fold shutter actuator, SwitchA 8f= 8-fold switch actuator, PB 2f= 2-fold
push-button
Channel number + its function, e.g. Ch1_on/off
Functioning location of channel, e.g. R12

Example:
SubDB_H1F3_ SwitchA_4f(1)_R12_Ch1_L05,

Ch2_L06,Ch3_L07,Ch4_L08_on/off
Means: Lights 5-8 in room 12, 3rd floor of the first house, switching, executed at
switch actuator no. 1, which is installed in the distribution board on the 3rd floor.

7 Group addresses Advanced

7.1 Structure of the addresses

ETS offers 3 options for structuring addresses:
a) 2-level (historically from ETS1, practically not used anymore)
b) 3-level (used in ETS2 and ETS3, also suitable for larger projects, fixed folder sizes
and quantities on 3 hierarchical levels)
c) Free address structure: The user can set up his own, interlinked structures within
the entire 16 bit address range.
