Key Features:

  • Automated M-Bus device search streamlines the commissioning process.
  • Support for both M-Bus primary and secondary addresses enhances flexibility.
  • Baudrate options ranging from 300 to 9600, with 2400 Baud recommended for optimal performance.
  • Templates tailored for Modbus devices expedite setup and configuration.

Elevate your commissioning process with our efficient M-Center, ensuring a smooth and error-free transition into operational use.


Integration into Energy Management per ISO 50001

Seamless Integration with ISO 50001 Energy Management

Our open and inclusive energy management system seamlessly reads all energy meters equipped with M-Bus interfaces compliant with EN 13757-2, -3. If necessary, customized device drivers can be generated on the EMU M-Center, exported, and then applied to other M-Bus devices. Naturally, all captured measurements are meticulously archived and transmitted to the centralized Energy Management System.

Integration into Existing Systems


Additionally, the M-Center serves as an ideal system component for system integration by BACnet IP or MQTT.

The M-Center and the registered M-Bus participants are recognized as separate device objects with a static listing of analog input objects (measurements). Integration into an overarching BACnet IP system is almost configuration-free.
