The SIMATIC-ET‑200pro system allows safe communication limited to the system itself to be
established:
● The ET-200pro system is node on the PROFIBUS or PROFINET.
● Within the ET-200pro system, the interface module with integrated fail-safe control
(IM154 F-CPU) controls the inverter safety functions via PROFIsafe.

Figure 4-4 Shared device is possible with every inverter
The PROFINET "Shared Device" function allows two controls to access the same
PROFINET IO device, e.g. on a SIMATIC ET 200 I/O system or on an inverter. Typical
applications for "Shared Device" are systems, in which a standard CPU and a fail-safe CPU
are used as separate controllers:
● The fail-safe controller (F-CPU) is responsible for the safety functions in the inverter or in
the SIMATIC ET 200 I/O system.
● The standard controller transfers all other signals.
