Functions
The selected application and its parameters as well as input and output configuration deter-
mine 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 pres-
sure 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 sta-
tions 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.
