Your benefits

  • Intelligent link between M-Bus devices and system:
    The new M-Bus Hub leaves nothing to be desired in terms of flexibility and application diversity and makes data integration easier than ever before
  • Flexibility in data transfer:
    Sending the measured values ​​via email, storing them remotely on servers or querying the data online via the integrated web server are all possible with minimal effort
  • Unique capabilities:
    With the M-Bus Hub it is possible to seamlessly integrate an M-Bus system into surrounding systems such as building management systems via Modbus TCP, JSON-RPC or REST without additional devices

Applications

  • Quick and easy measurement data acquisition incl. integrated statistics functions
  • Integration of measurement data into (building) control systems or other peripheral systems
  • Complete gateway integration based on DLMS or REST, for example

Product information

Technical Data
Metering Gateway
CMe3100 An M-Bus metering gateway for the fixed network that reads up to 256 meters, compiles the meter data in customer-specific reports and delivers them to a receiving system via the fixed network or mobile radio according to a defined schedule and integration protocol.
M-Bus extenders (depending on version)
CMeX11S-CM2X13S Is an M-Bus master that extends the number of meters that a CMe3100 can use by providing additional driver power.
