Thanks Eric, You've gone to some trouble there. And thats the one I have. Moeller charged me $100au ($180us) for cable and $50au for software v4.0 which dumps memory at power down, and cant be configured not to. I'm not going back there.
Schnieder throw it all in with Zelio, Relay is cheaper, and they offered 20% discount. But then I asked for more i/o's and cable doesn't come with that one. Never mind. They are great little toys aren't they. I've never worked on PLCs before (and you could say "still haven't") but these were a good intro for me. Thanks again.
Jon.
