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).

the way to analysis of your system.
TIA Selection Tool
The TIA Selection Tool tool supports you in the selection, configuration, and ordering of
devices for Totally Integrated Automation (TIA).
As successor of the SIMATIC Selection Tools , the TIA Selection Tool assembles the already
known configurators for automation technology into a single tool.
With the TIA Selection Tool , you can generate a complete order list from your product
selection or product configuration.
You can find the TIA Selection Tool on the Internet.
(https://support.industry.siemens.com/cs/ww/en/view/109767888)
SIMATIC Automation Tool
You can use the SIMATIC Automation Tool to perform commissioning and maintenance
activities on various SIMATIC S7 stations as bulk operations independent of TIA Portal.
The SIMATIC Automation Tool offers a wide range of functions:
•Scanning of a PROFINET/Ethernet system network and identification of all connected CPUs
•Assignment of addresses (IP, subnet, Gateway) and device 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
•CPU localization through LED flashing
•Reading out of CPU error information
•Reading the CPU diagnostic buffer
•Reset to factory settings
•Firmware update of the CPU and connected modules
You can find the SIMATIC Automation Tool on the Internet.

PRONETA
SIEMENS PRONETA (PROFINET network analysis) is a commissioning and diagnostic tool for
PROFINET networks. PRONETA Basic has two core functions:
•In the network analysis, you get an overview of the PROFINET topology. Compare a real
configuration with a reference installation or make simple parameter changes, e.g. to the
names and IP addresses of the devices.
•The "IO test" is a simple and rapid test of the wiring and the module configuration of a
plant, including documentation of the test results.
You can find SIEMENS PRONETA Basic on the Internet:
(https://support.industry.siemens.com/cs/ww/en/view/67460624)
SIEMENS PRONETA Professional is a licensed product that offers you additional functions. It
offers you simple asset management in PROFINET networks and supports operators of
automation systems in automatic data collection/acquisition of the components used through
various functions:
•The user interface (API) offers an access point to the automation cell to automate the scan
functions using MQTT or a command line.
•With PROFIenergy diagnostics, you can quickly detect the current pause mode or the
readiness for operation of devices that support PROFIenergy and change these as needed.
•The data record wizard supports PROFINET developers in reading and writing acyclic
PROFINET data records quickly and easily without PLC and engineering.
You can find SIEMENS PRONETA Professional on the Internet.
(https://www.siemens.com/proneta-professional)
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
