configurators for automation technology into one 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
(http://w3.siemens.com/mcms/topics/en/simatic/tia-selection-tool).
SIMATIC Automation Tool
You can use the SIMATIC Automation Tool to perform commissioning and maintenance
activities simultaneously on various SIMATIC S7 stations as a bulk operation independent of
TIA Portal.
The SIMATIC Automation Tool provides a multitude of functions:
•Scanning of a PROFINET/Ethernet system 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
•RUN/STOP mode switchover
•CPU localization by means of LED flashing
•Reading out of CPU error information
•Reading of the CPU diagnostics buffer
•Reset to factory settings
•Firmware update 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
SIEMENS PRONETA (PROFINET network analysis) allows you to analyze the plant network
during commissioning. PRONETA features two core functions:
•The topology overview automatically scans the PROFINET and all connected components.
•The IO check is a fast test of the wiring and the module configuration of a plant.
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 the optimal use of
resources
