The CPU 317F-2 DP allows a fail-safe automation system to be implemented for plants with increased safety requirements, especially in manufacturing automation.

Distributed I/O stations containing fail-safe I/O modules can be connected through the two integrated PROFIBUS DP interfaces. The fail-safe I/O modules of ET 200M can also be installed in central and safety-related configurations.

The safety-oriented communication between the F-CPU and the fail-safe I/O modules is performed on the basis of the PROFIsafe profile.

A SIMATIC Micro Memory Card is required for operation of the CPU.
