22.4.7 PX KNX integration (PXC001.D/-E.D)
These limits also apply to PXC00-U.
The maximum number of devices only applies in cases where only one device
type is used. The following formula applies to mixed operation with third-party
devices: 50 * RXB + third-party devices < 2,000 data points.
Item Limit Description
KNX/EIB data points [2,000*] Max. number of KNX data points that can be integrated (KNX
communication objects).
RXB 45 Max. number of RXB devices per KNX (approx. 50 KNX data points
per RXB, depending on the application).
