yes. use 0 and 1 registers

immediately after connecting to LM

and I can write data from Modbus Poll. But from one type PCL i can not. and from other type PLC I can only when I write float

yes

I think maybe my controller starts reading not from 0, but from 16 bits. therefore, he understands part of the float as integer. And i need to do offset. is it possible?
