Communication – network
Communication standards specially developed for building systems
Compliant devices can be interconnected at low cost using the BACnet (Building Automation and Control network) open communication
protocol. The worldwide BACnet standard was developed specifically for the needs of building services.
Desigo CC is an open management platform built on a proven SCADA technology and supports a variety of open system protocols and IT
standards. Thanks to the support of the BACnet Life Safety objects, simple and secure connection to fire detection systems such as Sinte-
so FS20 or Cerberus PRO to Desigo is possible without problems.
BACnet, KNX and LW
For the exchange of information among its own system components, Desigo uses for building automation three standard protocols,
recognized worldwide: BACnet, KNX (EIB) and LW. Desigo uses the BACnet communication protocol to exchange information
between the individual Desigo PX automation stations and the Desigo TRA room automation stations on the one hand, and to the Desigo
management platform on the other.
Desigo uses IP, LonTalk or MS/TP as the transport medium.
Furthermore, Desigo supports integration of BACnet/MSTP subsystems. The PXG3 router provides transparent BACnet traffic between the
MSTP and IP network (BACnet/IPv4 as well as BACnet/IPv6) and, optionally, to LonTalk as an addition.
The integrated KNX connection on Desigo TRAs room automation station PXC3 and DXR permits direct integration of both devices with
the KNX PL-Link as well as KNX S-Mode in Desigo TRA. Communication between room automation stations and field devices with KNX PL-
Link is optimized within the framework of the KNX standard for available plug-and-play functionality including automatic device recogni-
tion. Desigo Tools parameterize devices with the KNX PL-Link; the KNX commissioning software (ETS) is not required. A broad selection of
Siemens field devices, including room operator units, buttons, motion detectors, or VAV compact controllers support the KNX PL-Link.
Also, the Desigo RX room automation product range communicates per LM standard or KNX S-Mode (EIB).
BACnet certification
All Desigo PX and TRA BACnet servers as well as the Desigo management platform were submitted to the BACnet Interest Group
Europe (BIG-EU) for compliance testing based on the BACnet standard DIN EN ISO 16484-5 and successfully certified. A well-
known testing institution conducted the comprehensive testing.
The management platform, as well as the automation and room automation stations are all implemented as full BACnet nodes.
BACnet is integrated directly without the need for any special data conversion.
The Desigo PX automation stations satisfy the B-BC profile (BACnet Building Controller). Desigo CC and Desigo Insight satisfy the B-AWS
profile (BACnet advanced workstation). The Desigo TRA room automation stations support a BACnet object’s scope (BACnet B-ASC profi-
le) adjusted to room automation.
Web Services
Using RESTful technology, Desigo CC provides alarm, object and time series data via web based services to any 3rd party application.
AMEV guideline
Open communication between various systems using a common automation and operating concept are key functions for energy-saving
and reliable plant operation. As a consequence, Desigo meets in full the AMEV guideline V1.2 with the following profiles:
• Desigo management: AMEV profiles MBE-A and MBE-B
• Desigo PX: AMEV profiles AS-A and AS-B
OPC Foundation Certification
The Desigo CC managment platform is designed as an open platform and supports various open standard communication protocols and
IT standards such as OPC client and server for the OLE process control or ONVIF standard for IP-based video surveillance.
OPC is the interoperability standard for the secure and reliable exchange of data in the automation space and in other
industries. Desigo CC has been certified by the OPC Foundation meaning it has been tested and has passed independent
OPC testing. The benefits of using OPC certified products include faster configuration and start-up with fewer support calls,
proven reliability and interoperability, minimal integration risks and an investment in quality.
