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 only form one element of such a concept.

Customer is responsible to prevent unauthorized access to its plants, systems, machines

and networks. Systems, machines and components should only be connected to the

enterprise network or the internet if and to the extent necessary and with appropriate security

measures (e.g. use of firewalls and network segmentation) in place.

Additionally, Siemens’ guidance on appropriate security measures should be taken into

account. For more information about industrial security, please visit

(http://www.siemens.com/industrialsecurity).

Siemens’ products and solutions undergo continuous development to make them more

secure. Siemens strongly recommends to apply product updates as soon as available and to

always use the latest product versions. Use of product versions that are no longer supported,

and failure to apply latest updates may increase customer’s exposure to cyber threats.

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

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

SIMATIC Automation Tool

You can use the SIMATIC Automation Tool to run commissioning and maintenance activities

simultaneously on various SIMATIC S7 stations as a bulk operation independently of the TIA

Portal.

The SIMATIC Automation Tool provides a multitude of functions:

●Scanning of a PROFINET/Ethernet 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

●Operating mode switchover RUN/STOP

●Localization of the CPU by means of LED flashing

●Reading out CPU error information

●Reading the CPU diagnostic buffer

●Reset to factory settings

●Updating the firmware 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

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

network during commissioning. PRONETA features two core functions:

●The topology overview independently scans PROFINET 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).
