Our Products

EMU M-Bus Centre

M-Bus data logger with integrated web-server, Internet of things and Industrie 4.0 ready with M-Bus to BACnet IP and OPC UA


The M-Bus Center is configured entirely using an appealing, user-friendly interface operable with any customary web browser (HTML5). The graphic display shows the IP address configured manually or obtained via DHCP.

M-Bus to BACnet IP Gateway
The M-Bus Center is furthermore an ideal system component for integration into a BACnet IP network. Once an M-Bus meter is registered or imported to a Center, it is immediately readable via the BACnet IP. The M-Bus Center and the registered M-Bus slaves are each detected as separate device objects with a static list of analogue input objects (M-Bus value). Integration into a higher-level BACnet IP system requires no configuration.
