I had it left over from an automation project I was helping someone out with, I used to use it for roadtesting programs. It's a Siemens Step7 214. Was thinking of doing a couple of timespans like 10 seconds (fast changing) and 1-2 minutes for a slow change. I can't go too complex though as i'm gonna have to reproduce the ladder logic using SSR's and 555 timer IC's.
