M-Bus data logger

EMU M-Bus Center

EMU M-Bus Center

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

Made in Switzerland  

Flexible and expandable

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.

    2400 baud recommended

Anbindung an Energiemanagement nach ISO 50001

Plug & Play communication to
energy management and billing software.

As an open energy management system, all energy meters with M-Bus are read. If necessary, individual device drivers can be created. All available measured values are archived and transferred to the higher-level energy management and billing system e.g. EMU Joulio-Web



Protection of investment

The open communication and Gateway functions
allow our energy meters and data loggers to communicate
with systems of different manufacturers.
This protects your hardware and installation investments.
