Performance segments of fail-safe CPUs
The fail-safe CPUs are intended for users who want to implement demanding standard and
fail-safe applications both centrally and decentrally.
These fail-safe CPUs allow the processing of standard and safety programs on a single CPU.
This allows fail-safe data to be evaluated in the standard user program. The integration also
provides the system advantages and the extensive functionality of SIMATIC for fail-safe
applications.
The fail-safe CPUs are 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 13849-1:2015 or EN ISO 13849-
1:2015
