MBus Introduction
      M-Bus remote meter reading system (symmetrical mbus) is a European standard 2-wire two bus system, mainly used for consuming measuring instruments such as heat meters and water meters, flow meter series.
      Mbus bus is a European standard, and the main difference from ordinary 485 bus is:
      1. The Mbus bus operates with a working voltage of 30-36V for instrument data transmission; The general operating voltage of 485 bus is around 3.8V;
      2. Mbus can fully support star connection bus, while 485 bus usually requires hand in hand series connection;
Working principle of MBus concentrator
      Sunfull MBus concentrator is connected to the instrument Mbus bus through the Mbus interface and then converted to RS485 level mode, which allows the PC upper computer or serial device to access the terminal instrument.
