Modbus profile generator

[Shunsuke Baba]

Hi,

I’m trying to write the configuration for the following Modbus device but haven’t been able to get it right, so I’d appreciate your help.
When each register holds an 8-bit value and two registers together form a 16-bit integer, how should I define it?

Register addresses (hex)ataByte Size
• 0x1C: Temperature (Low Byte):1 byte
• 0x1D: Temperature (High Byte): 1 byte
–15.0 °C to 90.0 °C (raw values 0xFF6A to 0x0384)

My failed Configration :
[
  {
    "bus_datatype": "int16",
    "datatype": "int16",
    "address": 28,
    "read_count": 2,
    "units": "°C",
    "type": "register",
    "value_multiplier": 0.1,
    "name": "Temperature"
  }
]

Thank you for reading.
