Modbus datapoint type

[daniel.r]

Hi
I have a De Dietrich air conditioning machine and I need to read the values from the attached table.

When I am in the Modbus tab and in the option to read address, what type of data do I choose?

Sometimes it gives me absurd values always starting from Holding Register.

Thanks in advance.

Uint32, the data may need some conversion like multiply by X, Play with the read swap too.
Also try subtracting register nr by 1 as we start count from zero and some from 1.
