Preface
Recycling and disposal
Security information
The products are low in pollutants and can be recycled. For environmentally compliant
recycling and disposal of your electronic waste, please contact a company certified for the
disposal of electronic waste.
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
(http://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under (http://www.siemens.com/industrialsecurity).

2.1 What is the SIMATIC ET 200SP distributed I/O system?
Thanks to its multifunctionality, the SIMATIC ET 200SP distributed I/O system is suitable for
a wide range of applications. Its scalable design allows you to tailor your configuration to
local requirements. Different CPUs/interface modules are available for connection to
PROFINET IO or PROFIBUS DP.
SIMATIC ET 200SP with CPU allows intelligent pre-processing to relieve the higher-level
controller. The CPU can also be used as standalone device.
By using fail-safe CPUs, you can implement applications for safety engineering.
Configuration and programming of your safety program takes place the same way as for
standard CPUs.
A wide range of I/O modules rounds off the product range.
SIMATIC ET 200SP is designed with degree of protection IP20 and is intended for
installation in a control cabinet.
The SIMATIC ET 200SP distributed I/O system is installed on a mounting rail. It consists of:
● CPU/interface module
● Up to 64 I/O modules, which can be plugged into BaseUnits in any combination
● Up to 31 motor starters
● A server module that completes the configuration of the ET 200SP.

2.2 What are fail-safe automation systems and fail-safe modules?
Fail-safe automation systems (F-systems) are used in systems with higher safety
requirements. F-systems control processes and ensure that they are in a safe state
immediately after shutdown. In other words, F-systems control processes in which an
immediate shutdown does not endanger persons or the environment.
Safety Integrated is the integrated safety concept for automation and drive technology from
Siemens.
Proven technologies and systems from automation technology are used for safety systems.
Safety Integrated includes the complete safety sequence, ranging from sensor, actuator and
fail-safe modules right through to the controller, including safety-related communication via
standard fieldbuses. Drives and controllers handle safety tasks in addition to their actual
functions.
The key difference between fail-safe modules (F-modules) and standard modules is that they
have an internal two-channel design. This means the two integrated processors monitor
each other, automatically test the input and output circuits, and switch the fail-safe module to
a safe state in the event of a fault.
The F-CPU communicates with a fail-safe module via the safety-related PROFIsafe bus
profile.
Fail-safe motor starters enable safety-related tripping of motor loads. Fail-safe motor starters
are not PROFIsafe nodes. Motor starters operate together with the fail-safe modules of the
ET 200SP system.
By using the ET 200SP distributed I/O system with fail-safe I/O modules, you are replacing
conventional safety engineering configurations. This includes the replacement of switching
devices for emergency STOP, protective door monitors, two-hand operation, etc.

2.3 How are SIMATIC Safety F-systems structured 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.
Figure 2-3 Fail-safe SIMATIC Safety automation system (sample configuration)
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.
Fail-safe motor starters are suitable for safety-related tripping of motor loads.
