M-Bus to Modbus Converter

Description

CMBUS protocol transducers enable devices with RS-485 Modbus Master communications to communicate with different M-BUS slave units.

There are two unit models:

• The CMBUS-8 model can communicate with 8 slave units (100 parameters).
• The CMBUS-24 model can communicate with 24 slave units (500 parameters)

Applications

In Northern and Central European installations there are many devices that log consumption, equipped with M-BUS communications protocols or interfaces. These equipments measure cold and hot water consumption, as well steam, gas, electricity, etc. Said equipments deliver characteristic parameters of the systems they control, such as, water temperature, volume, flow, pressure or electrical energy consumption, as well as the more basic parameters of an electrical network. The M-BUS (BUS-Meter) protocol is a communications system for reading energy meters that has been designed to automate data collection by remote control or computer programs.
