SIMATIC S7-300
Central processing units
CPU 312C to CPU 317F-2 DP
■ CPU 317F-2 DP
• The failsafe CPU with a large program memory and quantity
framework for demanding applications
• For configuration of a failsaf e automation system for plants
with increased safety requirements
• Complies with safety requiremen ts up to SIL 3 to IEC 61508,
AK6 to DIN V 19250 and Cat. 4 to EN 954-1
4
• Without additional wiring of the failsafe I/O
• 1x PROFIBUS DP master/slave interface and 1 x DP mas-
ter/slave/MPI interface
• Both interfaces can be used to integrate failsafe modules
• Distributed connection of failsafe ET200S PROFIsafe I/O
modules possible;
Central and distributed connection of failsafe ET200M I/O
modules possible
• Central and distributed use of standard modules for
non-safety-relevant applications
Micro memory card required for operation of CPU.
