Your benefits
- Intelligent link between system and M-Bus devices:
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
Properties
- Data can be sent to FTP and https server
- Different executions with support for 8, 32, 64, 128, 256 or 512 devices available
- Various templates available for sending meter data
- Integration of wireless M-Bus participants (T & C mode) with CMi-Box
- DIN mounted, modular and expandable – future-proof solution
- Various extension modules (infrared interface) available
- Supports static and dynamic IP addressing
- Configuration changes and ad hoc read-out can be carried out remotely
- M-Bus protocol according to EN 13757-3
- Two M-Bus slave outputs for splitting the system to further systems
- Flexible extension system TCP, JSON-RPC, DLMS/REST

1) The maximum possible network reach (entire cable length) as well as the distance to the M-Bus end devices depends greatly on the network
topology, the number of connected devices, the cross-section of the used cables and the transfer rate.
