I just purchased one of these off ebay for a home project, but I can't find any docs anywhere. I have reverse engineered the pinouts on the I/O ports, so I can connect to it and use it, but I would still like docs if possible. Does anyone have docs or know where I can get docs for this beastie? Anyone know what it was for? It seems to be a naked C200H series PLC, but the I/O boards show up as being on expansion racks instead of the main rack... Its a nice compact unit however, perfect for home automation or some such thing, just not very expandable. Thanks for any help! Mike
