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
product 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 notifications 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 controller.
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 Safety - Configuring and
Programming (https://support.automation.siemens.com/WW/view/en/54110126).
