You can look in the TAB "learn PLC's" in the head of this page.. or are you looking something special?

Where do you need this information for?
i need an article for taking a certificate.i have to translate it so i want a short(about 2 sheet!!!) one about use of plc and anything else...just an article!
I will give him the benefit of the doubt and say this is to demonstrate his ability in technical translation and not a presentation of the final article as his own original work.
Here is a 3-page article, "Specifications for the Phase III Motor Tester". I wrote and own this article, so there is no problem with copyrights or trademarks.
