BACnet communication router UBR | LON

LANRS485IP

Communication intermediary between two worlds MBS GmbH has developed a Universal BACnet Router (UBR) which links BACnet over LonTalk to BACnet/IP. It gives property operators an inexpensive way of connecting facility engineering based on BACnet over LonTalk to the modern IP technology. The LON field bus performance standard (Local Operating Network, ISO 14908-x) with the LonTalk communication protocol is one of the world's most popular building automation technologies. The idea behind it is, at the automation level, to establish a topology decentrally and using existing structures in enclosures and buildings – for example as stars, rings or lines. This enables integrated networking and brings great flexibility to the system as a whole. Yet when fixed-network telephony is switched over to Voice over Internet Protocol (VoIP), telephone alarm systems suffer a communication gap. Closing the communication gap The VoIP has become increasingly well-established and will continue to do so. According to the German Federal Network Agency, there were 25.5 million VoIP connections in Germany by late 2018, and the figure was rising. But controllers that use BACnet over LonTalk and issue alerts by phone are not suitable for IP telephony. So, this type of alert system no longer works when the existing phone line is switched to VoIP. For such cases, MBS has added the Universal BACnet Router UBR | LON to its product line. It mediates between these two worlds, because it converts the data that is transported by BACnet over LonTalk to IP-capable information.
