Functional safety in a decentralzied architecture

The fail-safe SIMATIC controllers enable the processing of standard and safety programs on a single controller. The CPU 151xSP F fail-safe controllers are extended standard ET 200SP CPUs. They are certified according to EN 61508 (2nd Edition) for functional safety and are suitable for use in safety-related applications up to SIL 3 according to IEC 62061 and PL e according to ISO 13849.

The CPU 151xSP F fail-safe controllers can be used as PROFINET IO controller or as distributed intelligence (PROFINET I-device). The CPUs 151xSP F can be expanded both centrally with standard and fail-safe ET 200SP modules, and distributed via PROFINET/PROFIsafe with any ET 200 systems.
The expandable PROFINET IO IRT interface is designed as a 2-port switch so that a line structure can be configured in the plant.
For IT security, additional password protection is set up for F-configuration and F-programs..

The CPU 1510SP F-1 PN is the entry-level CPU for standard and fail-safe applications with medium requirements for processing power and reaction speed in discrete manufacturing technology. The CPU 1510SP F-1 PN can be used as PROFINET IO controller or as distributed intelligence (PROFINET I-device).

The CPU 1512SP F-1 PN  is the CPU for standard and fail-safe applications with medium requirements for processing performance and reaction speed in discrete manufacturing technology. The CPU 1512SPF -1 PN can be used as PROFINET IO controller or as distributed intelligence (PROFINET I-device).
