Standalone operation at field level
The room automation system can be operated as a standalone system. All the
necessary functions can be implemented by means of the KNX communications
between RXB controllers, and between these and any KNX-compatible third-party
equipment.
Integration into the automation level
There are different possibilities for integrating RXB controllers into a building
automation and control system:
• The PX-KNX integration station, which converts the KNX communications objects
into BACnet data points. Typically up to 45 RXB controllers can be integrated per PX
KNX interface controller.
• The OCI700 interface, which converts KNX information into USB format.
