Hi all,
i would like to develop a simple modbus Server, over RS485, with python. I have siemens PLC as master and i want write data in the holding register of server..
What is the best package to do this?

Thanks in advance!

Hello,
I've had success using modbus-tk:

But that has been years ago, so there might be a better alternative available.
