4 Optimizing Safety Programs

Optimizing Safety Programs

4.1

Optimizing the compilation duration and runtime

Introduction

User programming protection by coded processing is an important part of a safety

program (see Chapter 5). The objective is to detect any data corruption in the

safety program and thus prevent non-safe states.

This protection program is generated during the compilation, which extends the

compilation duration. The protection program also extends the F-CPU's runtime as

the F-CPU additionally processes this program and compares the results with the

user program.

You will find the protection program that is automatically generated by the system

in the system block folder of your F-CPU.

Some of the instructions that can be used in the safety program influence a fail-

safe controller's performance to a greater extent than others.

This chapter shows different options for reducing the compilation and program

runtime.
