If you want generic info, search for PLC tutorial. If you want specific, you will need to visit www.software.rockwell.com, or just search for Rockwell Automation. Be prepared to spend $$ for this training.
After replying to that thread about conduit bending videos, I thought I'd recommend all 3 books by Richard Cox. They are very thorough and informative, they are available to purchase online via his site, and his service is excellent. He has books on conduit bending, motor control, and PLCs.
