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

We want to make this site a collection of S7 related articles and handy links. 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.


"STAR - LIB"  open source library for Step7 projects:

This project is started & maintained by Mayasin, an experienced and creative S7 programmer.

Check out this smart replacement for the standard timer functions
It contains replacements for all standard timer functions T_ODT, T_OFFDT etc.

Using this library brings important advances:

  • no more restrictions with Timer-numbers (S5 Timers)
  • no longer consume large data areas with S7-timers like FB4 (only 1 DINT is required for internal use)
  • SCL-source is included
