Safety Integrated for process automation


For system availability SIMATIC S7-400FH controllers with redundant CPUs are used in order to meet all requirements in terms of safety and fault-tolerance.

For use as a safety-oriented controller, the user can extend the standard CPU with safety-related functions using the S7-F systems software package.This enables standard, safety and fault-tolerant tasks to be integrated cost-effectively into the standard automation system.

Two CPUs, CPU 414-4H or CPU 417-4H, are available for SIMATIC S7-400FH in order to accommodate a variety of performance requirements.


Field of application

The SIMATIC S7-400FH controllers are particularly suitable for applications that demand maximum safety, fault-tolerance and availability.
