Could you get started with Arduino? (Disclaimer: I don't know a lot about what PLCs actually do -- maybe that's too basic for you.)

Right now I'm trying to hack my treadmill with an Arduino unit so I can control it with software, and I'm learning a ton. Plus it's not a huge investment.

I had come across Building Arduino PLCs: The essential techniques you need to develop Arduino-based PLCs when i was looking for something similar a while ago. You might find it a good starting point.
