i want to know general theoretical background about PLC, and how dose it work. i need to prepare a worksheet talks about control using PLC, and how the person can convert the manual machines to full automated machines.

 

Go to the Schneider (Modicon) web site "public.modicon.com":http://public.modicon.com and click on "WHAT IS.. A PLC?".
