C-Bus Integration with BACnet

Does your Building Automation System speak BACnet? Do you need to integrate Honeywell C-Bus? We have a solution for you - our C-Bus to BACnet gateway. Based on our proven IEC converter technology we provide the direct translation between both protocols.

The CB-100 Honeywell C-Bus to BACnet gateway allows a Honeywell EXCEL 5000® System integration into a BACnet/IP network. The CB-100 gateway converts C-Bus data points into the BACnet point objects and transforms the C-Bus attributes into the BACnet properties. On the BACnet side, the whole C-Bus appears as one BACnet device. The CB-100 gateway monitors the C-Bus alarm events using the enrollment object and passes the alarms to the notification class recipients. The CB-100 gateway provides the web interface for the C-Bus Time Program editing. Device and point discovery allows the integration of sites where no detailed information about the C-Bus installation is available. To commission the gateway, you need only a web browser, and you do not have to install any legacy management tools. The CB-100 gateway is manufactured in the EU and delivered in the DIN rail enclosure.
