M-Bus vs Modbus.
M-Bus and Modbus solve different parts of an integration problem. M-Bus is commonly used on the meter side, while Modbus RTU over RS-485 is common on PLC, BMS and SCADA host systems.
Practical distinction
In many projects an automation controller uses RS-485 while the meters use M-Bus. A converter therefore provides host communication on one side and M-Bus Master signalling on the meter side.
Host segment
Host segment
RS-485 connects to PLC, BMS or SCADA equipment.
Repeater option
Repeater option
An additional M-Bus Slave input can allow upstream M-Bus repeater operation.
