Automating With STEP
7 in STL and SCL
S7-300/400 Programmable Controllers
By Hans Berger
This 4th Edition
is Updated to Include The Latest Version of STEP 7
list (STL) and structured control language (SCL) are the
text-oriented programming languages in the programming software STEP
Now in its fourth edition, this book is an
introduction into the latest version of STEP 7. It describes
elements and applications for use with both SIMATIC S7-300 and
SIMATIC S7-400, including the applications with PROFINET. It is
aimed at all users of SIMATIC S7 controllers.
First-time users are introduced to the field
of programmable controllers, while advanced users learn about
specific applications of the SIMATIC S7 automation system.
SIMATIC is the worldwide established
automation system for implementing industrial control systems for
machines, manufacturing plants and industrial processes. Relevant
open-loop and closed-loop control tasks are formulated in various
programming languages with the programming software STEP 7.
All programming examples found in the book -
and even a few extra examples - are available at the download area
of the publisher's website.
