Hi Mohammed,

I think forum readers might need some more information before they can offer assistance ...

Can you describe the exact problem that you are having? What limitation do you see?

Can you describe your application and communication topology?
For example, do you want to use the pyboard as a Modbus client to control a device using Modbus TCP,
or do you want the pyboard to act as a Modbus slave and have another device poll data from the pyboard using Modbus RTU over a RS-485 serial line?

It also can help to include an example of your code which illustrates the problem you are having
