Ok

I have already used the fileexcel and it is very useful my problem is to understand how the registers are addressed.
EXAMPLE
I have a DB in the PLC which contains the values and which I pass to the modbus TCP server
in the db I have the first real value PLC address 0.0 which register corresponds to 1? datatype I guess 9 is a holding register, writable.

Thanks so much
