EEP structure
Each EEP is identified using three fields:
◼
RORG
RORG identifies the high-level telegram type, e.g. rocker switch telegram (RPS), one-
byte sensor telegram (1BS), four-byte sensor telegram (4BS), variable length tele-
gram (VLD), Universal Teach-in with EEP (UTE), etc.
◼
FUNC
FUNC identifies the function group to which this telegram belongs, e.g. the function
group of temperature sensors within the four-byte sensor telegram type
◼
VARIANT (or TYPE)
VARIANT (which is confusingly also called TYPE) identifies the exact sensor variant
within the function group, e.g. a 0 °C
–
40 °C temperature sensor that is defined
within the function group of temperature sensors
Figure 19 below shows the structure of the EEP identifier.

EEP identifier structure
The EEP identifier is typically only transmitted during the initial teach-in (paring) between
devices. For special cases (e.g. devices using more than one EEP), data telegrams might
specify the EEP that is used.
