DEOS BACnet/SC BMS - New standards in safe building automation
At #ISH 2025 / Hall 11.1 - D88 / we will show you our innovations and solutions for modern building management.
At ISH, we will be presenting our three scalable BMS solutions - for different building sizes and requirements, whether locally on the automation station, server-based and on-site or as a cloud BMS. The BMS solutions can be expanded with DEOS site networking or with the IoT platform developed in-house by DEOS. This ensures that the buildings are always operated at the optimum energy level.
*** The difference
Only a few I&C manufacturers like DEOS offer an IT-secure BACnet/SC-certified complete system - from the BMS to the automation station. This is where we at DEOS make the most of our many years of BACnet expertise:
DEOS has been one of the early BACnet pioneers of interoperable solutions since 2005 and has been supporting our own BACnet experts for more than 20 years.
*** The highlight
Onboard-GLT/-MBE - the integrated and powerful HTML5 web server with basic BMS functions for small projects directly on the automation station.
Server and cloud GLT/MBE - full BMS functions when the functional requirements or number of buildings increase
Easily scalable - the system graphics created on the DEOS Controller can continue to be used in OPENweb without any additional effort.
Consistently secure - BACnet/SC certified from the OPEN.WRX AS automation station to the OPENweb BACnet/SC BMS
BACnet/SC - with over 55 years of expertise, we have launched the world's first BACnet/SC security-certified automation station, setting new standards in IT security in building automation.
Graphic & simple - Thanks to the standardised graphic system display, employees can monitor and set the room and system parameters without prior knowledge
*** The references
Agrippabad in Cologne - whether remote access or on-site operation via the centrally installed building management system (BMS): the conversion to the BACnet/SC-certified DEOS OPENweb BMS during operation now makes it much easier to monitor and control all systems in the Agrippabad.
*** Three points in conclusion
We focus on the right solutions for each project size, speed and simplicity in scaling, installation and operation, as well as end-to-end BACnet/SC security through certification.
