Function circuit diagrams and priorities

The function tables show the effect of various KNX commands when a function is parametrized.
The following should be noted here.
Note
Priorities in the gateway from highest to lowest:
1. Forced operation/Block function
2. Partial failure function
3. Manual operation
4. Slave/Staircase lighting/Scene/KNX telegrams function
Note
The Burn-in function sets the minimal dimming value on the ballast to 100%. This sets all brightness
values other than 0 to 100%. The same applies for the Forced operation und Scenes functions.
For instance, this means that if a ballast or the group is in burn-in mode, a forced operation is mapped
from 50% to 100%.
Note
If the i-bus
follows:

Note
If either the Forced operation/Block or Partial failure function is activated, the gateway only updates
incoming KNX commands in the background. The system reacts as follows in this case:
Switch, Brightness value and Scenes commands are invisibly executed in the background, memorizing
the end brightness values immediately without transition times. Dimming commands are ignored.
Operating states, e.g. inactive or standby, for the Slave and Staircase lighting functions are also
memorized in the background depending on the incoming KNX commands. If the Staircase lighting is
active when the higher-level function ends, it is in standby. If slave mode is active, it responds to its
master again as soon as the higher-level function ends.
Once the higher-level function ends, the ballast or group adopts the brightness value that would have
occurred if the higher-level function had not been executed.

Provided the i-bus Tool is in View mode ( ), it has no effect via KNX functions.
If configuration mode ( ) is activated and the DALI window has been opened, all KNX functions
(e.g. forced operation or staircase lighting) are deactivated or set to standby. This is the only way to
carry out consistent commissioning. On exiting the i-bus

Tool the functions must be reactivated.
