Thanks for your replies..
I did briefly take a look at custom built plc's some time ago however the costs would be out of my budget.
Because I am an absolute bacon to the RPI and programming in general at the moment I am scratching around reading the beginner tutorials my aim for now would be something along the lines of turning an led on and off over the internet or similar.

For now ive decided to move away from the breadboard tutorials and focus more on the very basic linux code.....
