Hello
I have a problem with modbus communication - or rather with the received data.

I did communication with the module. I am downloading information from address 3008.
In SIWATOOL i see 4.0, by modbus I get 16512 (DEC in wash/only for example) for Floating-point number 16#0000_4080.

How can I read / do a conversion to get exactly what SIWATOOL sees
To get the value 3008 I set in the PLC block MB_CLIENT [MB_DATA_ADDR:=43008] length 2.

I will just add that I'm not interested WP241-HMI communication - here everything works fine (i have reado_for_use_projects).



thanks
Tomek
