Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Security information
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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.

SINETPLAN
SINETPLAN, the Siemens Network Planner, supports you in planning automation systems and
networks based on PROFINET. The tool facilitates professional and predictive dimensioning of
your PROFINET installation as early as in the planning stage. In addition, SINETPLAN supports
you during network optimization and helps you to exploit network resources optimally and to
plan reserves. This helps to prevent problems in commissioning or failures during productive
operation even in advance of a planned operation. This increases the availability of the
production plant and helps improve operational safety.
The advantages at a glance
•Network optimization thanks to port-specific calculation of the network load
•Increased production availability thanks to online scan and verification of existing systems
•Transparency before commissioning through importing and simulation of existing STEP 7
projects
•Efficiency through securing existing investments in the long term and the optimal use of
resources

2.1 What is the SIMATIC ET 200AL distributed I/O system?
SIMATIC ET 200AL
The SIMATIC ET 200AL distributed I/O system is a scalable and highly flexible, distributed I/O
system for connecting process signals to a higher-level control system with a field bus.

Area of application
The SIMATIC ET 200AL distributed I/O system is especially well suited for use in tight spaces,
moving applications and for assembly and handling technology. Thanks to its scalable
construction, you have the option to precisely customize its configuration to your on site
needs.
The SIMATIC ET 200AL distributed I/O system features degree of protection IP65/IP67. The I/O
modules are suitable for distributed use indoors on a machine or assembly line.
Setup
The SIMATIC ET 200AL distributed I/O system is made up of the following components:
•Interface modules (PROFINET/PROFIBUS)
•Digital and analog I/O modules
•Communication module
After an interface module you can configure 2 lines (ET-Connection), each with 16 modules.
Alternatively, you can configure a line with 16 I/O modules on the SIMATIC ET 200SP
distributed I/O system with BaseUnit BU-Send and the BusAdapter BA-Send 1xFC.
The ET-Connection backplane bus is designed as a cable. This allows you to create spatial
distances of up to 15 m between the modules.

Distributed I/O system
System Manual, 08/2021, A5E31861578-AJ 17
2.2 What are fail-safe automation systems and fail-safe modules?
Fail-safe automation systems
Fail-safe automation systems are mainly used in applications where failure could have
consequences for the safety of people and/or the environment. Fail-safe systems are
therefore intended to reduce hazards or failures that could cause physical damage. Their
purpose is to ensure a tolerable level of risk.
F-systems are used to control processes and provide a safe operating state when faults are
detected. Fault detection is ensured by a very high level of diagnostic coverage. When a fault
is detected, appropriate actions are initiated to bring the affected application to a safe state.
F-systems offer improved fault detection and fault localization through detailed diagnostics
and diagnostic messages. This is the most important difference between fail-safe systems and
standard systems. The use of fail-safe systems should be considered for applications where
hazards are inherent and can cause physical damage.
Safety Integrated
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.
Fail-safe modules
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.
Possible uses of ET 200AL with fail-safe modules
The use of ET 200AL with fail-safe modules makes it possible to replace conventional
mounting technology in safety technology with PLC components. This also includes the
replacement of switchgear for EMERGENCY STOP, safety door monitoring, ambidextrous
operation, etc.
Fail-safe modules for ET 200AL are supported together with the STEP 7 Safety Advanced V17
or higher option package.
F-modules for ET 200AL can be used either with an ET 200AL PROFINET interface module
(IM), a direct ET connection to an ET 200SP F-CPU or a direct ET connection to an ET 200SP IM
(mixed configuration).

System overview
2.2 What are fail-safe automation systems and fail-safe modules?
Distributed I/O system
18 System Manual, 08/2021, A5E31861578-AJ
Use in SIMATIC Safety F-systems
The fail-safe ET 200AL modules can be used with STEP 7 Safety Advanced from V17 with
PROFINET and direct ET connection configurations together with an F-CPU.
The fail-safe modules can only be used in safety mode. Fault safe and non-fault safe modules
can be combined within one ET 200AL ET connection.
Achievable safety classes
The fail-safe modules are equipped with integrated safety functions for safety mode.
You can achieve the safety classes of the table below:
•With the appropriate parameter assignment of the safety functions in STEP 7
•With a specific combination of fail-safe and non-fail-safe I/O modules
•With a special arrangement and wiring of the sensors and actuators

WARNING
The safety performance of your installation depends on the design and ongoing
maintenance of the individual complete safety function.
SIMATIC fail-safe CPUs and ET 200AL fail-safe modules have logic processing components
with certified safety integrity levels, provided they are operated in accordance with
classifications, specifications, and instructions.
Failure to adhere to this may cause damage or unpredictable operation, resulting in fatal or
serious injury and/or property damage.
To achieve the level of safety you require, you need to select all components of your plant
and construct and maintain them in accordance with accepted safety standards and
practices.
