Applications
A comprehensive block library for room automation is provided as part the
scope of delivery. The library contains predefined application functions for room
climate, lighting, shading, and superimposed room functions. The applications
can be combined with operating and display functions as required. The
individual application functions can be adapted to customer needs and are
programmable. The application functions do not depend on the selected field
devices.
See
Application Catalog .
Configuration of application functions
Many application functions are preconfigured and available in the library.
Retroactive configuration during engineering or commissioning is possible. Your
own configured application functions and entire rooms can be stored in a
project library.
Configuration of field devices
The application architecture does not depend on the field device interface.
Field devices can be connected directly to the PXC3 room automation station
(via TX-I/O modules) or via bus (KNX or DALI) or IP communication.
Many field devices are preconfigured and available in the library. Retroactive
configuration during engineering or commissioning is possible. Project-specific
field devices configured accordingly can be saved in a project library.
Modular room automation stations
PXC3 room automation stations with control functions for one or multiple
rooms:
● Assume control functions for one or multiple rooms.
● Communicate with each other or other system components via BACnet/IP.
Scope and functionality of supported BACnet objects are matched to the
requirements of room automation.
● Provide a 2-port Ethernet interface for cost-effective cabling via daisy
chaining.
● Contain bus supplies for island bus, KNX PL-Link, and DALI. Internal bus
supplies can be extended for island bus and KNX PL-Link as needed.
● Have an integrated web server for IP communication with QMX7.E38 touch
room operator units.
