S5-115F Manual

Preface

The S5-115F is a failsafe programmable controller for the lower and mid performance ranges. It is
for use wherever safety is the first priority and where potential dangers must be avoided.
Hardwired solutions have dominated failsafe technology until now. With the S5-115F, you can
now apply all the advantages of our programmable controllers (PLCs) to your safety-related
controls. You write your process-oriented program as before and then enter all safety-related data
with the COM 115F programming software.
You require detailed information in order to use the controller to its best advantage.
This manual aims to provide the necessary information in condensed form without overloading
the user with superfluous knowledge, which means:
• Standardization of terminology and spelling
• More detailed breakdown of subjects
• Illustration of individual problems
• User-friendly arrangement of the contents
• Particular observance of the rules of safety technology
In this way, you will gain all the information required to operate your S5-115F. This manual is
aimed at:
• Users with little previous experience
• SIMATIC S5 experts
• Officials conducting Licensing Authority acceptance tests.
However, the applications are so numerous that not all the problems that might occur can be dealt
with in one manual. You will find a list of Siemens representatives in the Appendix who will help
you in those cases where the manual cannot answer your questions.
