Your benefits

  • Intelligent link between M-Bus devices and system:
    The CMe3100 M-Bus metering gateway fulfils all requirements in terms of flexibility and versatility and makes data integration easier than ever before
  • Flexible meter reading:
    Reading of the measured values by the time-saving online query via the web platform or on site
  • Unique capabilities:
    Whereas previously it was difficult to connect an M-Bus system via Modbus TCP, JSON-RPC or REST, the CMe3100 enables integration into peripheral systems, e. g. a building management system, without additional devices
  • Preferred M-Bus splitter:
    The CMe3100 supports the complete M-Bus standard, and splitting all bus participants to two further systems via wired M-Bus is easy
  • Infrared interface for modular extensions:
    Metering gateway can be used for the connection of additional measuring points (––> investment protection)

Applications

  • Fast and simple measurement data acquisition incl. integrated statistical functions
  • Integration of measurement data in (building) management systems or other peripheral systems
  • Complete gateway integration based on e.g. DLMS or REST
