Functions
The selected application and its parameters as well as input and output configuration determine
the room automation station's functionality.
A detailed description of functionality is available in the ABT (Automation Building Tool) online
help.
Communication
● For critical environment DXRs with fume hood controls, all controllers in a pressurized space
must be on a common switch
● 2-Port Ethernet switch for cost-effective cabling via line topology
● USB connection for service and commissioning, firmware download, and LAN access
● SCOM (sensor communication) for fast and high resolution communication with a pressure
sensor and sash open area module (SOAM). Up to 5 devices are supported
● The following functions are available with the KNX PL-Link bus:
– Communication with room operator units, operator display panels, switches, sensors,
actuators, and luminaires
– Plug-and-play connection of Siemens field devices with KNX PL-Link
– Integration of KNX S-Mode devices (ETS engineering required)

Technical design
Voltage supply
The supply provides controlled voltages for inputs and outputs. The room automation stations
also supply AC 24 V and DC 24 V field supply. The supply is located in the device to simplify
wiring and diagnostics.
The processor controls voltage supply. This ensures clean conditions for the field devices
connected to the I/Os during startup, shutdown, and undervoltage.
Bus power supply
The room automation station includes the bus power for KNX PL-Link. The bus power is
switched on by default, but can be switched off via a web interface or configuration in the
Automation Building Tool (ABT).
