 The last digit x refers to the current version of the software profile.
ETS is informed about the underneath mentioned system profiles through the
following mask versions:

2
 y01xh: System 1
 y02xh: System 2
3
 y70xh: System 7
4
 y7Bxh: System B
 y300h: LTE
 091xh: TP Line/backbone coupler – Repeater
 190xh: Media coupler TP-PL110
 2010h: RF bi-directional devices
 2110h: RF unidirectional devices

Unidirectional devices can basically not be configured by ETS. Only e.g. gateways which
communicate with these devices can be configured by ETS. Bi-directional RF-BCUs can
currently not be configured by ETS. The goal is to make this possible as of ETS 5.

Temporary values of the system and the application: These are lost when there is
a bus power down (if not stored earlier in non-volatile memory by the device).

the application program, the physical and group addresses: these are usually
stored in memory that can be overwritten.

In the case of S-mode compatible devices, the manufacturer makes the application
program available to the installer as an ETS product entry, who then loads it into the
device. The manufacturer code of the application program and the bus coupling unit must
match to be able to load the application program.
In the case of E-mode devices, the device reports the supported functionality (as regards
supported “Easy” channels) by means of the device descriptor 2.
