How are SIMATIC Safety F-systems structured with ET 200SP?
SIMATIC Safety F-system with ET 200SP
The figure below shows an example of a configuration for a SIMATIC Safety F-system with
ET 200SP distributed I/O system and PROFINET IO. The PROFINET IO lines can be set up
with copper cable, fiber-optic cable or WLAN.
Fail-safe I/O modules and non-fail-safe I/O modules can be combined in an ET 200SP
configuration.
The fail-safe IO controller (F-CPU) exchanges safety-related and non-safety-related data
with fail-safe and non-fail-safe ET 200SP modules.

Fail-safe ET 200SP I/O modules
The following fail-safe I/O modules are available for the ET 200SP distributed I/O system:
● Fail-safe power modules are used to supply the potential group load voltage and for the
safety-related tripping of the load voltage for non-fail-safe output modules.
● 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 are suitable for safety-related shutdown procedures with
short circuit and cross-circuit protection up to the actuator.
ET 200SP fail-safe motor starters
Fail-safe motor starters are suitable for safety-related tripping of motor loads.
