Oh my gawd, its 5000 dollars for the software. Maybe I need a 500 series unit for a trainer but will Allen Bradley give me RSLinx and the whats it called? Micrologix Lite? I started down this road once before with a micrologix controller but lost interest with it because it was so small. I dunno, this is a dealbreaker, my boss just gave me this thing, maybe i ought to take it back if its worth any amount of money, perhaps they could sell it. Besides it would be unethical to keep it if he didnt know its value. Hell, theres three more of em and as far as I know they are dumpster bound. Thanks Paul
