Registers are always 16 bits, so float32 is divided over 2 registers, please try type input register (function code 4 according to manual)
BR,

Yes, this was the cause, but for the frequency this is not solution, but I will be 100% confident when I will tomorrow connect counter as should be because now it is only connected to 1 phase and frequency is the parameter of all 3 phases so it could be the cause of this second issue. Thanks Erwin, you're the best
After a few minutes, register starts respond. A little strange but true. But still there are some errors in communication(timeout errors).
