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.

To stay informed about product updates, subscribe to the Siemens Industrial Security RSS

Feed under (https://www.siemens.com/industrialsecurity).

Open Source Software

Open-source software is used in the firmware of the I/O modules. Open Source Software is

provided free of charge. We are liable for the product described, including the open-source

software contained in it, pursuant to the conditions applicable to the product. Siemens

accepts no liability for the use of the open source software over and above the intended

program sequence, or for any faults caused by modifications to the software.

For legal reasons, we are obliged to publish the original text of the license conditions and

PRONETA

With SIEMENS PRONETA (PROFINET network analysis), you analyze the PROFINET

network during commissioning. PRONETA features two core functions:

●The topology overview independently scans PROFINET network and all connected

components.

●The IO check is a fast test of the wiring and the module configuration of a system.

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 optimal exploitation

of resources

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