The room automation stations communicate with each other and other system
components via BACnet/IP (DXR2.E…) or BACnet MS/TP (DXR2.M...).
The room automation stations support different I/O mixes, protocols (KNX S-
Mode and KNX PL-Link for IP and KNX PL-Link for MS/TP) and power
supplies (240/24V). Operating devices, buttons, sensors, and actuators for
lighting and shading can be connected to the room automation stations via KNX
PL-Link.
The room automation stations contain preloaded applications, but are also
freely programmable. A comprehensive library of proven, standardized
applications is available.
The DXR2.. room automation stations have an integrated web server for IP
communication with QMX7.E38 touch room operator units. Engineering access
is available via the web interface.
Desigo RXB
The RXB room controllers control the room climate in individual rooms and
important parameters of the applications can be configured.
The RXB room controllers communicate via KNX.
The PX KNX system controller connects the room automation devices to Desigo
PX and the management level and assumes coordination functions for room
automation (grouping, scheduling, demand signal exchange, peer-to-peer, etc.).

Acvatix Intelligent Valve
Acvatix Intelligent Valve is a pre-loaded device with a specific application. The
Desigo tool environment supports the Intelligent Valve to allow smooth and
lean BACnet/IP integration into Desigo projects.
See
Intelligent Valve Datasheet (A6V11444716)
Use case
Acvatix Intelligent Valve acts as a control valve within a PX primary system. The
Intelligent Valve communicates via BACnet IP.
