Use
Starting with Desigo V5, PXC3 series room automation stations with Total Room
Automation applications (TRA) can be used for buildings with more sophisticated
requirements on functionality and flexibility. TRA is used when several disciplines
(HVAC, lighting, shading) are combined to form one total solution and when total
flexibility is required. TRA is perfect for solutions optimizing energy (class A)
without loss of comfort.
Functions
A PXC3 series room automation station can assume control for multiple rooms.
These programmable room automation stations provide the infrastructure to
provide and process system- and application-specific functions.

If V6 applications are loaded into a V5.1 device, less rooms are supported,
because V6 applications require more memory space.

• The room automation stations have a 2-port Ethernet switch to support for lowcost cabling via line topology.
• A USB Device port is available for service and commissioning.
• TX-I/O modules connected directly to the PXC3 allow for direct connection of
field devices. This offers maximum flexibility.
• The KNX PL-Link peripheral bus supports room operator units, sensors, and
actuating devices. Selected Siemens field devices to the KNX PL-Link bus
(devices with the KNX PL-Link logo) can be connected.
The KNX PL-Link bus supports integration of commercially available devices
with KNX S-Mode (requires ETS engineering).
• The DALI bus supports lighting control. Commercially available DALI EBGs
(electronic ballasts) can be connected.
Equipment combinations
Depending on the type, PXC3 series room automation stations can be operated
with TX-I/O devices and devices with KNX PL-Link.

Island bus cover (supplied with the device)
The bus supplies for island bus, KNX PL-Link and DALI are integrated in the room
automation station.
For better reliability of the room automation station, the bus supplies and the
AC 24 V outlets are independent from the room automations station's own supply.
V6: The bus supplies are switched on by default and can be swiched off via tool if
not needed.
V5.1: The bus supplies are switched off automatically as long as no device is
connected to the respective bus during engineering.
V5.1 devices do NOT support the V6 functionality of field bus supply management.
The internal KNX PL-Link supply must not be operated in parallel with an
external supply. It must be switched off via tool when using an external supply.
This is typically the case if the devices connected to the KNX PL-Link consume
more than the 160 mA available from the internal supply.
