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.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Special information
Note
Important note for maintaining the operational safety of your plant
Plants with safety
-related features are subject to special operational safety requirements on
the part of the operator. The supplier is also required to comply with certain measures for
pr
oduct monitoring. Siemens informs system operators in the form of personal notifications
about product developments and properties which may be or become important issues in
terms of operational safety.
You need to subscribe to the corresponding notificat
ions to ensure that you always remain
up
-to-date and are able to make any necessary changes to your plant regarding operational
safety should the need arise.

Note
Increased safety measures
Anywhere that errors can cause injury or property damage, special standards must be applied
to the safety of the entire plant. Special, plant
-specific rules exist for this purpose, which
must also be taken into account by the owner when setting up the cont
roller.
For electronic controllers with safety responsibility, the measures that must be taken to
prevent or control errors are based on the risk posed by the plant. For this, the owner must
ensure implementation of additional measures for the plant, e.g.
use of safety-related
controllers such as the S7-1500 F fail-safe automation system.
Note
When using F
-CPUs in safety mode and fail-safe modules, note the description of the fail-safe
system SIMATIC Safety Programming and Operating Manual SIMATIC Safet

2.1 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.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed visit (https://www.siemens.com/cert).
