Hierarchical grouping
The four different configurations for central functions can also be used for hierarchical grouping.
Reason and benefits of hierarchical grouping:
- Engineering and commissioning in stages
- Structured network topology

The bundled exchange of data between the building level and floor level takes place on the automation station at the floor level (Cen-Flr).
Sensor placement
Additional sensors can be connected directly via analog or digital I/Os to the automation on the floor level (Cen-Flr). The function belonging to the sensor must be configured each time on the DXR2.
Recommendation
For simplification, the four configurations described in the following sections for central functions also describe the application for hierarchical grouping. The four central function configurations are placed on the automation station at the building level (Cen-Bldg). Also described is the data exchange on the required automation station on the floor level (Cen-Flr).
