What is it that you are trying to do? 
Some of the commercial devices come with their own software, and
you may not need python or anything else.
A lot of the industrial connectivity is still RS-485 or RS-422 and not
Ethernet based - although some of the protocols, have, I think, been ported.

If you say more, then someone can maybe help you, as there are quite a few
people on this group who seem to dabble in process control.
