Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
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.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Tools
The tools described below support you in all steps: from planning, over commissioning, all
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)

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

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
