pymodbus is still pretty much the standard for modbus communication. For profinet you'll want to look at python-snap7 if youre working with siemens PLCs. Both have decent docs. Just be aware that industrial protocols can be tricky - make sure you test everything thoroughly before deploying. Also consider using opcua instead if possible, its much easier to work with and python-opcua is excellent.

Working on a factory automation project and need to communicate with PLCs and various sensors over modbus and profinet. What python libraries would you recommend? I've used pymodbus before but wondering if there are better alternatives now. Also need something with good documentation since im still learning.
