System overview
4.2 Configuration
SIMATIC Safety F-system with S7-1500 and ET 200MP
The figure below contains an example of an F-system SIMATIC Safety with S7-1500,
ET 200MP and PROFINET IO.
You can combine fail-safe I/O modules and non-fail-safe I/O modules in a can be combined in
a S7-1500/ET 200MPconfiguration.
The fail-safe IO controller (F-CPU) exchanges:
• Safety-related data with fail-safe modules.
• Non-safety-related data with non-fail-safe modules.

Fail-safe I/O modules S7-1500/ET 200MP
The following fail-safe I/O modules are available for S7-1500/ET 200MP:
• Fail-safe digital input modules detect the signal states of safety-related sensors and send
the relevant safety frames to the F-CPU.
• Fail-safe digital output modules control actuators for safety-oriented tasks.
