Introduction

M-Bus (Meter-Bus) is a communication interface widely used in various meters, such as electricity meters, watermeters, heat meters, etc. Ease of installation (two-wire system includes power and communication function) androbustness are the most important features. M-Bus has its own physical layer and protocol. Therefore, it is usuallyswitched to other systems, such as Modbus, to facilitate the overall application.

Applications

The M-Bus (MeterïBus) is a bus optimized for the reading of measurement instruments like: energy counters, hot and cold water counters, gas, pressure, sensors and actuators, etc..
