Product overview
2.1 Application
Safety Integrated
The fail-safe CPU is intended for users who want to implement demanding standard and fail-
safe applications both centrally and decentrally.
The fail-safe CPU enables the processing of standard and safety programs on a single CPU.
This allows fail-safe data to be evaluated in the standard user program. As a result of this
integration, the system advantages and the extensive functionality of SIMATIC are also
available for fail-safe applications.
The fail-safe CPU is certified for use in safety mode up to:
● Safety class (Safety Integrity Level) SIL 3 according to IEC 61508:2010
● Performance Level (PL) e and Category 4 according to ISO 13849-1:2006 or according to
EN ISO 13849-1:2008
Additional password protection for F-configuration and F-program is set up for IT security.
System diagnostics
Integrated system diagnostics is enabled by default for the CPUs. The different types of
diagnostics are configured instead of programmed. System diagnostic information is shown
uniformly and in plain text in STEP 7, on the HMI and on the Web server, even alarms of the
drives. This information is available in RUN mode, but also in STOP mode of the CPU. The
diagnostic information is updated automatically when you configure new hardware
components.
