The OPEN EMS controller series supports the BACnet device profile BACnet Building Controller (B-BC) and can be used simultaneously as BACnet servers, clients and routers.

  • B-ASC Controllers
    In addition, we also offer various BACnet devices with the BACnet Application Specified Controller (B-ASC) device profile. The following devices are designed as BACnet servers for the field level and are based on BACnet MS/TP data link layer:
    -Our freely programmable single room unit SRU
    -Various actuators, such as air flap drives and water valves
    -The GALAXY One and CORA room control units
    -The BACnet MS/TP radio receiver, as a gateway solution, for coupling EnOcean sensors and actuators with BACnet

  • B-OWS / BACnet BMS
    Our OPENweb building management systems have natively implemented the BACnet protocol according to its BACnet Operator Workstation (B-OWS) profile. OPENweb allows you to integrate plants and systems from different manufacturers and provides you with worldwide access to your BACnet data thanks to the client/server principle.

For your information: What is BACnet?

BACnet stands for Building Automation and Control Networks and is an open and independent communication protocol for building automation, which takes into consideration all levels, including field levels, automation levels and management levels. BACnet was initially developed as a standard by ASHRAE – American Society of Heating, Refrigerating and Air-Conditioning Engineers – before it was also adopted as the European standard DIN EN ISO 16484-5 in 2003.

The standard defines BACnet Interoperability Building Blocks (BIBBs). They determine which services are supported on the server and client side. In addition, each BACnet product includes a manufacturer-specific Protocol Implementation Conformance Statement (PICS), which lists the supported BIBBs, object types, character sets and BACnet communication options. Thanks to this standard, BACnet ensures the open interoperability between products from different manufacturers in technical building automation.
