The S7-Tools site is created in october 2006 by a group of experienced Step7 users. 

We want to make this site a collection of S7 related articles. We publish our own articles, publish articles of other users and supply you with links to other Simatic related sites that might be interesting for you.

With our news flashes we keep you up to date with the latest Simatic S7 related information so you don't have to browse all articles yourself to find the S7 related news.

News, experiences, suggestions, questions and comments are welcome
