System functions
Communication – network
MODBUS IP
Desigo CC support the MODBUS communication protocol, allowing for example a seamless integration of power meters at the manage-
ment level.
DALI, EnOcean
DALI, EnOcean, and KNX devices turn the PXC3 room automation stations of Desigo TRA into a complete solution for the room.
The optional DALI bus of the room automation stations allow for simple integration of different lamps and luminaires. DALI (Digital
Addressable Lighting Interface) is a worldwide standard that applies specifically to lighting control at cost-efficient two-wire technology
and integrated power supply.
Self-powered EnOcean radio technology offers wireless connection of field devices based on extremely energy-saving technology. The
operating energy required by the devices is taken directly from the environment. The wireless room units QAX9..4 can be used via En-
Ocean/LW or EnOcean/KNX gateway with Desigo TRA or RX.
S7 Protocol
Desigo CC integrates S7-300 and S7-400 natively, allowing the use of all standard workflows for also these Siemens devices.
Client/server options
The management platform Desigo CC offers flexible client-server architecture for building automation and fire protection applications.
It supports the configurations of small single-user systems to large multi-user installations. Desigo CC can be fully installed on a compu-
ter, with full client and server functionality. Additional clients (dedicated with browser as well as Windows desktop application) can be
easily added.
Desigo Touch and Web
Desigo Touch and Web permits operation and monitoring of the Desigo PX automation level using the Desigo touch panels PXM40 and
PXM50, as well as via standard Web browser (HTML5 technology) on various hardware platforms (e.g. tablets, notebooks/PCs, smartpho-
nes). The BACnet/IP Web interface PXG3.W100 supports flexible and remote access to the BACS via LAN/W-LAN connections in a straight-
forward manner.”
IT security
The protection against unauthorized or malicious access to building services systems and installations is becoming increasingly impor-
tant. Desigo CC, as modern management platform takes this into account and meets security level SL1 according to ISA-99/IEC 62443.
This includes securely handling of passwords with appropriate key strength and authorized system access only to elements (menus,
buttons, etc.) to which the user has at least read access.
Connection of legacy sytems
Desigo is compatible with the legacy automation systems Unigyr, Visonik, Integral or Simatic and allows their seamless integration.
Changes in use, system extension and retrofit projects can all be handled in gradual stages. For example, previously installed PTM-I/O
modules of Unigyr or Visonik can be connected directly to modular Desigo PXC..D automation stations. Existing actuators and sensors
can continue to be used that way.
