1 Introduction

Introduction

The new controller generation SIMATIC S7-1200 and S7-1500 has an up-to-date

system architecture and, together with TIA Portal, offers new and efficient

programming and configuration options.

If the programming is sloppy, the many options provided by STEP 7 can also

produce negative results:



CPU stops



Long compilation processes



Additional, comprehensive acceptance testing

This document provides you with many recommendations and notes for the optimal

configuration and programming of S7-1200/1500 controllers. This helps you create

standardized and optimal programming of your automation solutions.

The examples described in this document can be universally used on the S7-1200

and S7-1500 controllers.

Advantages

Following the recommendations given in this document provides you with many

advantages:



Reusability of program parts



Easier acceptance (code review, error detection and correction)



More flexibility in terms of program changes



Reduction of programming errors



Increased plant availability by avoiding CPU stops



Easier readability for third parties



Reduced runtime of the safety program

Note

Not all the recommendations provided in this document can be applied at the

same time. In these cases, it is up to you as the user to decide on the

prioritization of the recommendations (e.g., standardization or runtime

optimization of the safety program).
