SIMATIC Factory Safety

SIMATIC ET 200S F-CPU –
the intelligent, safety interface module

The safety-related, intelligent SIMATIC interface modules IM 151-7 F-CPU for the ET 200S are designed to meet the demands of the lower performance range.

They can be expanded in a centralized configuration with the safety ET 200S I/O modules or distributed via PROFIBUS or PROFINET. The intelligent ET 200S station can also be used as stand-alone, i.e. without PROFIBUS or PROFINET cable. Additionally the IM 151-7 F-CPU is also available as a PROFIBUS DP master which can be used with a standard controller or as a stand-alone CPU (incl. safety modules).

The IM 151-7 F-CPU offers a combined DP/MPI interface. Beside the IM 151-7 F-CPU offers a PROFINET interface with 3 ports. PROFINET line or ring topologies can be easily realised. E.g. additionally a programming device can be connected via the third available port. Additionally you get a comfortable access to the modules and diagnosis data by the integrated webserver.
