SIMATIC Factory Safety

Overview

Safety SIMATIC automation systems are used to control processes, and change into or remain in a safe state when a fault occurs. They provide an in­te­gra­ted, efficient safety concept in plants with particularly demanding safety re­quire­ments.

Compared with conventional safety technology, a safety SIMATIC also ena­bles intelligent system access up to and including the electrical drives and measuring systems. The improved fault localization thanks to comprehensive diagnostics information enables a fast continuation of production after a safety-related shutdown.

Product overview

Controllers

Modular controllers ET 200S F-CPUs: safety, intelligent interface modules for use on-site in the lower performance range S7-300F: safety CPUs for the mid to upper performance range S7-400F: safety CPUs for the top-end performance range Embedded Automation S7-mEC-RTX F: safety, embedded controller in S7-300 design pre-installed with Windows XP Embedded and the SIMATIC WinAC RTX F S7 software controller IPC427C-RTX F: safety, embedded, turnkey DIN rail PC pre-installed with Windows XP Embedded and the SIMATIC WinAC RTX F S7 software controller HMI IPC477C-RTX F: fail-safe panel PC pre-installed with Windows XP Embedded (Compact Flash Card) and S7 Software-Controller WinAC RTX F PC-based Controller WinAC RTX F: safety S7 software controller for PCs with Windows XP

The safety systems are based on a standard controller whose operating system and hardware components have been expanded with a variety of protective mechanisms.

I/O

ET 200M Can be used for centralized I/O configurations for the S7-300 and as distributed I/O via PROFIBUS with PROFIsafe profile ET 200S For distributed I/O configurations optional via PROFIBUS or PROFINET with PROFIsafe profile ET 200pro The modular and functional I/O in high degree of protection IP67 for the distributed installation optional via PROFIBUS or PROFINET with PROFIsafe profile ET 200eco The distributed digital block peripheral device in high degree of protection IP67 for PROFIBUS with PROFIsafe

The safety SIMATIC control­lers can be expanded by configuring the ET 200M, ET 200S, ET 200pro or ET 200eco stations with safety modules.
