Modbus to M-Bus with PiiGAB M-Bus 900S
The application Modbus2MBus for the PiiGAB M-Bus 900S is developed to enable communication via M-Bus with Modbus units on your existing M-Bus network. Your Modbus units will by using the application Modbus2MBus be seen as a virtual M-Bus meters on your M-Bus network. This will give you a unique opportunity to use both M-Bus and Modbus at the same M-Bus network.
The application Modbus2MBus is ordered as an addition to our gateway PiiGAB M-Bus 900S. You can connect up to 32 Modbus units per gateway/converter. For example, you can communicate with meters, heat pumps, cooling units, PLC, distributed I/O units etc. that are using the Modbus protocol. The gateway works as a translator between the two protocols. This allows M-Bus based systems to communicate directly with Modbus units.

|Extend the M-Bus network with Modbus|
In order to connect the Modbus units to your M-Bus-system you have to start the process from the Modbus units. The first step is to put in the address of your Modbus unit and then the M-Bus address, primary or secondary, it should be connected to. The next step is to put in what Modbus register you want to read and that is when the first M-Bus object is created automatically. The system adds on at the pace you are configuring the Modbus registers that you wish to read out. It is also possible to complement your Modbus register with more advanced M-Bus properties, such as what text and kind of value it should have (VIB), as well as which tariff the value should belong to etc.
