Modbus: can't write on ALDES INSPIRAIR_TOP_B120

[gdimaria]

Hi, 

I Create the attached modbus profile for the that Aldes module and I can't write on some register like the 257.

I asked their technical support and the answer was: 

"There is a particularity on Inspirair to write on a single register.

You need to select a length “2” to write on a single register.
For example to write on address 257 then you need to select register 256 with length 2 and write the value you need on address 257."



So how a have to modify the profile?

Thanks
