    That’s the reason, why the first value uses the index 4x1 and the second index uses the index 4x3. So this configurations uses four MODBUS registers with the indices 4x1, 4x2, 4x3 and 4x4. Date Page RESI-KNX-xxx manual Title: 12.12.2018...
  • Page 35 So the MODBUS register 4x5 stores the value 236 if the current temperature 23.66 is received from the KNX bus. You will also notice, that you can configure more than one line with the same KNX group address, but different MODBUS mappings. Date Page RESI-KNX-xxx manual Title: 12.12.2018...

  • Page 36: Functional Description

    The RESI-KNX-MODBUS and RESI-KNX-ASCII gateways communicate with a host system with the MODBUS/RTU slave protocol. The RESI-KNX-ASCII version of the module offer an additional protocol: An ASCII slave protocol with simple text string. The communication runs over a RS485 interface (half duplex) or over a RS232 interface (full duplex).
