Compliant devices can be interconnected at low cost using the BACnet (Building
Automation and Control network) open communications protocol. The worldwide
BACnet standard was developed specifically for the needs of building services,
under the auspices of ASHRAE (the American Society of Heating, Refrigerating
and Air-Conditioning Engineers). BACnet networks provide all subscribers with
access to all the data and functions of the connected devices.
For the exchange of information among its own system components, DESIGO uses
three standard protocols, recognized worldwide: BACnet, LONWORKS and Konnex
(KNX) S-mode (EIB). The BACnet communication protocol is used for the
exchange of information between one DESIGO PX automation station and another,
and between DESIGO PX and PXM20 BACnet operator units and DESIGO INSIGHT.
DESIGO/IP uses LonTalk or PTP (point-to-point, modem or null-modem) as the
transport medium. At the room automation, DESIGO RX communicates per
LONWORKS standard or KNX S-mode (EIB).
DESIGO Terminal Server and DESIGO WEB make optimum use of the advantages
of modern IT technology for the benefit of building services. Properly selected and
used, they have a significant influence on the ability to fine-tune the running of the
building and on the comfort and satisfaction of building users. This reduces
maintenance and upkeep costs.
DESIGO Terminal Server provides all the functions of the management system in
the form of terminal services over the network. These services can be accessed
simultaneously by different users in independent sessions. In addition to operation
and monitoring programs for the day-to-day operation of the plant, engineering
tools are also provided, allowing modification and expansion of the system while it
is running. This makes the DESIGO Terminal Server the optimum solution for
professional building operators who need unrestricted access to building data via
their intranet or extranet, from any location.
DESIGO WEB is a genuine Web solution based on Microsoft IIS (Internet
Information Server). The programs for operation of the management system are
mapped to ASPs (Active Server Pages) in special interfaces optimized for Microsoft
Internet Explorer.
All DESIGO PX BACnet servers were submitted to the BACnet Interest Group
Europe (BIG-EU) for compliance testing on the BACnet standard DIN EN ISO
16484-5 and successfully certified. A well-known testing institution conduced the
comprehensive testing.
DESIGO PX devices comply with the B-BC profile (BACnet Building Controller) and
DESIGO INSIGHT largely comply with the B-OWS profile (BACnet Operator
The management and automation stations are all implemented as full BACnet nodes.
BACnet is integrated directly without the need for any special conversion of data.
Workstation).
DESIGO is compatible with the legacy automation systems UNIGYR, VISONIK,
INTEGRAL and SIMATIC S7 and allows their seamless integration. Changes in
use, system expansion and retrofit projects can all be handled in gradual stages.
