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

It can be implemented as a PROFINET IO Controller and as a standard PROFIBUS DP Master in the SIMATIC S7-300. The CPU 317F-2 PN/DP can also be implemented as distributed intelligence (DP slave).

Distributed I/O stations containing fail-safe I/O modules can be connected via the two integrated interfaces. The fail-safe I/O modules of ET 200M can also be installed in central, 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.
