PICs in general

RS422 and RS485 are not internet controllers. They are mostly level converters that go between the uart and the wire. They allow the signal to cover long distances. Their are several lighting, building control, and industrial control networks that use them. I should know the names but I am rushed and they escape..

Ethernet controlers are a challenge for pros. I suggest you start with a RS485 network. What you are saying is that you are interested in rockets and want to start by building a space shuttle. Too complex! But you can get there in time.
