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.

•The room automation stations have a 2-port Ethernet switch to support for low-
cost 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.

Building Technologies 2015-11-23
The internal bus supplies can be reinforced by external power supply modules.
An additional TXS1.12F10 supply module must be switched on and off at the same
time as the room automation station. Otherwise, DC 24 V island bus supply may
sag, resulting in alarms.

Engineering
•Each device has a unique serial number for commissioning support.
It is also located on the removable barcode label: See the ABT online help for
the associated workflow.
•Each device has a unique MAC address.
•Each device with KNX PL-Link has a unique KNX ID.
•Cable length, topology, etc.: See installation manual Desigo TRA, CM111043.
Caution!
•The cable insulation must always comply with the present rated voltage.
•When the supply voltage of the room automation station is transited to external
devices, the cable cross section must always correspond to the rated current
of the safety circuit breaking device.
Observe local regulations in any case.
Mounting
The room automation stations can be snapped onto a standard mounting rail.
The automation station has pluggable screw terminal blocks to connect the AC 24
V supply, the AC 24 V outlets, the KNX PL-Link, and the DALI bus.
The TX-I/O modules are snapped onto the mounting rail on the right side of the
room automation station. The island bus is created automatically in this process.

*) 50 °C / 122 °F is admissible if the bus supplies use max. 2/3 of the specified
load: KNX PL-Link 105mA, DALI 85mA and island bus 400mA.
PXC3.E16A-100A: 50 °C / 122 °F is admissible without restrictions.
You must ensure, however, that sufficient ventilation is available to maintain
the permissible ambient temperature for the devices (inside the cabinet /
installation box).
Outside, the temperature must be 10 K lower.
Installation
See installation manual Desigo TRA, CM111043.
Island bus Polarity: If a TXS1.12F10 supply module is connected to output
24 V, do not invert ~ and ⊥.
The devices are not damaged but island bus communications will not work.
Operation
If island bus or USB communications do not work, this is an indicator that the
AC 24 V operating voltage is incorrectly wired (conductors ~ and ⏊inverted).
