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.

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

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

1.3.3 S7 Port Configuration Tool (S7-PCT)
SIMATIC S7-PCT
The Port Configuration Tool (PCT) is a PC-based software for the parameter assignment of
Siemens IO-Link Master modules and IO-Link devices from any manufacturer.
You integrate IO-Link-devices using the standardized device description "IODD", which you
get from the respective device manufacturer. S7-PCT supports version 1.0 and V1.1 of the
IODD.
S7-PCT is called via the hardware configuration of the IO-Link Master from STEP 7. When STEP
7 is not used or the IO-Link Master is not operated on a SIMATIC controller, "standalone"-
operation is also possible.
You can find additional information on IO-Link on the Internet
(https://new.siemens.com/global/en/products/automation/industrial-communication/io-
link.html).
1.3.4 MultiFieldbus Configuration Tool (MFCT)
MultiFieldbus Configuration Tool
MultiFieldbus Configuration Tool (MFCT) is a PC-based software and supports the
configuration of MultiFieldbus- and DALI-devices. In addition, the MFCT offers convenient
options for mass firmware updates of ET 200 devices with MultiFieldbus- support and reading
service data for many other Siemens devices.
Functional scope of the MFCT
•MultiFieldbus configuration:
Engineering, configuration and diagnostics of MultiFieldbus-devices, provision of the
required project files (project, UDT-, CSV- and EDS-file), transfer/export of the files to
device and/or data memory.
•DALI configuration:
Device selection and online configuration of DALI devices.
•TM FAST:
Generation and download of FPGA-UPD- and FPGA-DB-files.
•Maintenance:
Topology scan of a Ethernet network, reading of service data, parameter assignment and
firmware update.
•Settings:
Language switching German / English, network scanner speed, setting of the network
adapter, installation of GSDML-and EDS-files.
System/installation requirements for MFCT
The MFCT runs under Microsoft Windows and does not require installation or administrator
rights.
For MFCT you must also install the following software:
•Microsoft .NET Framework 4.8 (You can find an Offline Installer on the Internet.

2.6 Working on electrical parts
Only work on electrical parts if you are a qualified specialist (see section Target group and
personnel qualifications (Page 17)).
•Always observe the country-specific safety rules.
•Notify all those who will be affected by the procedure.
•Follow the 5 safety rules according to DIN EN 50110-1 (VDE 0105-1):
1. Disconnect
2. Secure to prevent reconnection
3. Verify safe isolation from the supply (all poles)
4. Ground and short-circuit
5. Erect barriers around or cover adjacent live parts
After completing work:
•Restore operational readiness in reverse order.
2.7 Residual risks
Despite all the technical and procedural risk reductions that have been carried out, not all
dangers can be avoided. The following sections describe these residual risks and measures to
avoid them.
2.7.1 Live parts
Operation
•Do not open the module.
•Do not use damaged modules.
•Pull the plug and not the cable.
Installation and connection
•Only work on electrical parts if you are a qualified specialist (see section Target group and
personnel qualifications (Page 17)).
•Adhere to the protective measures for safe working on electrical parts (see section
Working on electrical parts (Page 18))
•Fuse the connection cables according to the current-carrying capacity of the cable used,
taking into account the applicable standards.
•Ground the module according to regulations.
•For the 24VDC supply (SELV/PELV), only use power supply units that provide safe
electrical extra-low voltage in accordance with IEC 61131‑2 or IEC 61010‑2-201.
