Function diagram

The function chart indicates the sequence, in which the functions of the DLR/A are processed. If several
communication objects in the function block point to the same function, they have equal priority and are
processed in the sequence in which they are received.
Note
In principle, the priorities in the DALI Light Controller from the highest to the lowest are described in
simplified form in the following:
1.
2.
3.
4.
5.
Note
The function Slave has a higher priority than the additional function Staircase lighting with regard to the
parameterized behavior for incoming KNX telegrams.
The function Staircase lighting has a higher priority than the additional function Light control with regard
to the parameterized behavior for incoming KNX telegrams.
The function Burn-in does not interrupt a function. However, all brightness values not equal to 0 are set
to a brightness value of 100 %.
Test mode (manual operation) of a lighting group has a higher priority than forced operation and
blocking. When test mode ends, forced operation and blocking is re-enabled. The brightness values set
are those that were set before test mode.
The Software Tool continues to send telegrams while in test mode. These incoming KNX telegrams are
not executed. Nor are they stored intermediately. Commands incoming via the objects forced operation,
block and switch group are the exception. These commands are saved in the background and executed
when test mode ends.
Central telegrams interrupt the functions Slave, Light control and Staircase lighting of a lighting group.
The lighting groups undertake the central telegram. The functions switch to standby mode and must be
restarted/activated after completion/fulfillment of the central telegram by an ON telegram or activation of
the function.
