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/industrialsecurity).

activities simultaneously on various SIMATIC S7 stations as a bulk operation independent of
TIA Portal.
The SIMATIC Automation Tool provides a multitude of functions:
•Scanning of a PROFINET/Ethernet system network and identification of all connected CPUs
•Address assignment (IP, subnet, gateway) and station name (PROFINET device) to a CPU
•Transfer of the date and the programming device/PC time converted to UTC time to the
module
•Program download to CPU
•RUN/STOP mode switchover

•Reading of the CPU diagnostics buffer
•Reset to factory settings
•Firmware update of the CPU and connected modules
You can find the SIMATIC Automation Tool on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/98161300).
PRONETA
SIEMENS PRONETA (PROFINET network analysis) allows you to analyze the plant network
during commissioning. PRONETA features two core functions:
•The topology overview automatically scans the PROFINET and all connected components.
•The IO check is a fast test of the wiring and the module configuration of a plant.
You can find SIEMENS PRONETA on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/67460624).

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
You can find SINETPLAN on the Internet (https://www.siemens.com/sinetplan).
