Project design and programming
Example:
An EIB / KNX scene (no. 8) consisting of 4 lamps and 3 shutters which are
connected to two DALI-Gateways (1-fold and 8-fold) and 2 shutter actuators
can be recalled via a single EIB / KNX telegram. The prerequisite for this is
that all devices have programmed scene 8 accordingly in the devices. After
the receipt of the telegram, the two DALI-Gateways switch on their scene
with the number 8. This is carried out with the transition periods which have
been set in the gateway. The two shutter actuators move the 3 shutters into
the corresponding position at the same time.
Advantage: The 8-bit scene offers a few advantages in comparison to
conventional scene programming. On the one hand, only a single telegram
which is received by all participants in the scene and implemented
accordingly, is sent on the bus to retrieve a scene. On the other hand, the
target position of the shutter or the brightness of the DALI devices is stored
in the actuator or DALI-Gateway and does not need to be transferred via the
EIB after each recall.
The scene numbering 1 to 15 is retrieved via the EIB / KNX with
a telegram number 0 to 14. Refer to the key table in appendix A.6
for the corresponding scene codes.
The store scene command over the EIB / KNX includes all 128
DALI samples. This means that a scene stored with the object
„store scene" will include all 128 DALI samples. Every DALI
samples will get the brightness in the moment of the storage.
The brightness stored over the ETS parameterisation and the
mask (sample not part of the scene) are lost. The next
download will restore the stored calibration if the parameter
„overwrite scene on download" is set with „yes". Otherwise the
stored scene values are protected.
