This logic group controls e.g. lighting and shading, depending on partition walls, in a divisible hall.

The hall is divided into three sections and there is a separate KNX push-button for each section.
Thus, depending on the position of the partitions, this logic group can block or forward the switching commands accordingly.

Example:
If the two partitions are closed, the local push-buttons control only their own section.
If the partition between the 1st and 2nd sections is open, the two buttons switch the first and second sections.
When both partitions are open, the three buttons control the entire hall.

Via contacts in the partition walls, the control via the "door object" is enabled or blocked for the sections.
