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).
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

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
