Areas of Application of S7 Distributed Safety and S7 F/FH Systems
Use of S7 Distributed Safety
The primary uses of S7 Distributed Safety fail-safe systems are for machine and operator
protection (e.g., for emergency STOP devices for operation of machine tools and processing
machinery) and the process control industry (e.g., for protection functions for instrumentation
and control protective devices and burners).
Integration options for S7 Distributed Safety fail-safe systems at the plant automation level
are shown below.
