Modbus Profile incorrect value

[AlexLV]

Hi,

little help is needed. Value I received using my Modbus profile is invalid, please correct me.

Data from manual:

Export power
13010~13011
S32
1W
Power delivered by the inverter to power grid

Part of my profile:

{
      "name": "Export Power",
      "bus_datatype": "float32",
      "datatype": "int32",
      "type": "inputregister",
      "address": 13009,
      "units": "W"
    },

BR, Alex

Use Read test to find correct settings. You might need to use a different swap mode. Why do you map int32 to float32? This is not needed if you are using the value directly without setting value_multiplier.

You wrote "Why do you map int32 to float32"..

Ok, in that case both type will be the same? Float32? Or I just can delete bus and datatype from profile? What is correct if I use direct value?
I tested, I think I just need to put swap mode to "n"

"datatype" is how data in encoded on the Modbus side. "bus_datatype" is the mapped object data type.
In your case both "datatype" and "bus_datatype" should be "int32" because the value is not changed in any way.
