Pymodbus: how to use

Hi all, I need to comunicate with my machine with modbus protocol using pymodbus library.

as example I have a file containg the following table:
| Numero registro modbus | Dimensione (n*16 bit) | Descrizione |
|4 |1 |Temperatura modulo CPU|
|5 |1 |Tensione modulo CPU|
|3000 |1 |stato ingressi DIO16 1|

can someone give me an example for read and write informations using pymodbus?
thank you in advance
Best regards

There is a whole lot of examples in the pymodbus documentation.
