Have a look at This Page there are some links to PLC information that is in Dutch, French and good ol' English.

This site has a LEARN PLCS which also has HOW PLC WORKS. http://www.plcs.net/chapters/howworks4.htm

Siemens offers tutorials on a variety of subjects including PLCS which can be downloaded or viewed online.
