The CPU 315F-2 DP permits the design of a fail-safe automation system for plants with increased safety requirements, especially for production engineering.
Distributed I/O stations containing fail-safe I/O modules can be connected through the integrated PROFIBUS DP interface. The fail-safe I/O modules of ET 200M can also be centrally implemented safety-related.
Safety-related communication between the F CPU and the fail-safe I/O modules is performed on the basis of the PROFIsafe profile.
