Interfacing M-Bus meters to Modbus.
- Heat Meter
- Multical 601
Multical 601 M-Bus meters are required to be interfaced with the BMS.
- A M-Bus/Modbus converter (RS-485, RS-232 or TCP) and configuration software are required. The converter and software are available from SyxthSense or similar suppliers.
- Using the converter and software setup the M-Bus/Modbus system without the BMS system connected.
- The M-Bus/Modbus converter will automatically assign the M-Bus registers as Modbus registers. From the software note the tables and registers used.
- Create the Modbus registers as required for the BMS system used.
For Sigma - Create the gateway.txt, connect and configure the IC3-Modbus. A sample of the gateway.txt can be downloaded here.
