Fail-safe CPUs

CPU 416F

6/30

Siemens ST 70 · 2013

■

Overview

• For constructing a fail-safe automation system for plants with

increased safety requirements

• High-performance CPU in the top-end performance range

• Satisfies safety requirements up to SIL 3 acc. to IEC 61508

and Cat. 4 acc. to EN 954-1

• Standard and safety-related tasks can be performed with a

single CPU

• Multi-processor mode is possible

• Safety-related communication with distributed I/O devices

over PROFIBUS DP with the PROFIsafe profile

• Fail-safe I/O modules can be connected decentralized over

the integrated interfaces (DP and PN with CPU416F-3 PN/DP)

and/or through communication modules (CP443-5 Ext. and

CP443-1 Adv.)

• Standard modules for non-safety-related applications can be

operated centrally and decentralized
