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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity (https://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers’ exposure
to cyber threats.

1.1 Terminology
Industrial Ethernet
The term "Industrial Ethernet" covers a series of expansions to the Ethernet standard IEEE
802.3 with which communication suitable for an industrial environment is implemented. The
main aims are as follows:
●Deterministic data transmission - guaranteed response times and data rates
●Safeguarding against component failure
●Plant-specific network topologies with a focus on linear, redundant network structures.
The components must meet the following requirements:
●Industrial equipment, for example, signaling contacts, secure cables and plug-in
connectors
●Capability of withstanding extreme environmental conditions, for example extreme
temperatures, vibration, dust, dampness, electromagnetic interference.
PROFINET
The term PROFINET refers to the standard for Industrial Ethernet (IEC 61158/61784) that is
drawn up and supported by the Profibus & Profinet International (PI).
PROFINET unites protocols and specifications with which Industrial Ethernet meets the
requirements of industrial automation technology.
These include, for example:
●Real-time conditions
●Environment strongly affected by EMI
●High transmission safety, reliability and availability requirements
PROFINET contrasts with the office environment whose emphasis is more on high data
throughput and an extensive network. Further differences between the two network types
can be found in the numbers and heterogeneity of the nodes and their intermeshing.
SIMATIC NET
SIMATIC NET stands for a variety of network components that are available for innovative,
consistent realization of automation solutions under the umbrella of "Totally Integrated
Automation". PROFINET is the protocol that is used most often by SIMATIC NET
components in the context of the Industrial Ethernet.

1.2.1 Basics of Industrial Ethernet
Properties of Industrial Ethernet
Industrial Ethernet is a powerful communication medium complying with the international
standard IEEE 802.3 (Ethernet) that was designed for the requirements in an industrial
environment.
Ethernet was developed for the office environment and is subject to certain restrictions due
to its origins. Industrial Ethernet therefore offers significant expansions of the Ethernet
technology for the industrial environment:
●Protection of investment by connecting existing fieldbus systems
●Network components for use in a tough industrial environment
●Rugged and simple connection on-site through FastConnect cabling system:
–Assembly of copper cables with RJ45 and M12 technology
–Assembly of POF, PCF and glass fiber-optic cables (multimode)
●High transmission performance even with large numbers of nodes thanks to the end-to-
end availability of components with 10/100, 1 Gbps and 10 Gbps
●Ethernet with real-time capability that fulfils high requirements for the reaction time
(PROFINET IRT, TSN)
●Integrated security concepts for protection against unauthorized access
●High availability of the networks thanks to redundant functionality, for example ring
redundancy and redundant power supply
●Permanent monitoring of the network components with simple and effective signaling
concept
●Almost unlimited communication performance, since scalable performance available
through switching technology when necessary
●Networking of different areas of application such as office and production
●Procedure for extremely fast handover of mobile IWLAN nodes between different access
points and therefore fast cyclic data communication (iPCF and iPCF-MC)
●Communication throughout the enterprise with the option of linking via WAN (Wide Area
Network), such as DSL or mobile wireless, for example

Fast Ethernet
The Fast Ethernet standard IEEE 802.3u is an expansion of the existing standard (IEEE
802.3). Fast Ethernet is based essentially on the classic Ethernet standard for twisted pair
cables.
Ethernet and Fast Ethernet have the following common features:
●the CSMA access method
●the glass fiber-optic cable used and category 5 twisted pair cables
Fast Ethernet includes the following expansions / modifications:
●Data transmission rate up to 100 Mbps
●Autosensing, automatic detection of the transmission rate
●Autonegotiation, automatic detection of the functionality of the interface of the partner
●Full duplex mode
●Auto polarity exchange, automatic adaptation of the polarity if the wires of a cable pair are
swapped over.
●MDI/MDIX autocrossover, prevents malfunctions if transmit and receive cables are
crossed over.
Gigabit Ethernet
Gigabit Ethernet is an expansion of the Ethernet specifications to increase the data
transmission rate to 1 Gbps or 10 Gbps.
The relevant standards are as follows:
●IEEE 802.3z for transfer via glass fiber
●IEEE 802.3ab for electrical cables.
The increase in the transmission speed is achieved not only by adaptation of the protocol but
also by using category 5e, 6, 6A and 7 twisted pair cables that are particularly immune to
interference.
Differences compared with PROFINET
PROFINET expands Industrial Ethernet with the following additional properties:
●Transmission mode and real-time response
It can be guaranteed that frames are transferred within a specified time.
●Determinism
The same conditions always lead to the same results and there are no undefined
statuses.

1.2.2 PROFINET
1.2.2.1 Basics of PROFINET
What is PROFINET?
PROFINET is the open Industrial Ethernet standard (IEC 61918, for PROFINET also IEC
61158/61784) for industrial automation.
PROFINET uses the existing IT standards and allows end-to-end communication from the
field level to the management level as well as plant-wide engineering.
Aims of PROFINET
The aims of PROFINET are as follows:
●Open Ethernet standard for automation based on Industrial Ethernet.
Industrial Ethernet and standard Ethernet components can be used together, however
Industrial Ethernet devices are more rugged and therefore better suited to an industrial
environment (temperature, noise immunity etc.).
●Use of TCP/IP and IT standards
●Automation of applications with real-time requirements
●Seamless integration of fieldbus systems
PROFINET communication
PROFINET communication is divided into non real time (NRT), real time (RT) and
isochronous real time (IRT) communication, see section "Transmission procedures and real-
time response (Page 23)".

PROFINET profiles
PROFINET transfers data transparently. The interpretation of the data is the responsibility of
the user. The profiles are stipulations agreed by manufacturers and users relating to certain
properties, performance characteristics and behavior of devices and systems.
●PROFIdrive
The PROFIdrive profile (IEC 61800-7) defines the device behavior and the method of
accessing internal device data for electric drives on PROFIBUS and PROFINET.
The profile describes in detail how the communications functions direct data exchange,
constant bus cycle time and isochronous real time should be used in drive applications. It
also specifies all the device properties that influence the interface to a controller
connected via PROFIBUS or PROFINET. These include the state machine (sequence
control), the encoder interface, the standardization of values, the definition of standard
frames, access to drive parameters etc.
The PROFIdrive profile supports both central and distributed motion control concepts.
●PROFIsafe
The PROFIsafe profile (IEC 61508 / EN 954-1) defines how the safety-related devices
achieve fail-safe communication so that they can be used for safety-related applications.
The profile is a software solution that is implemented as an additional layer (PROFIsafe
layer) in the devices (e.g. operating system of the CPU). The safety-relevant data is
included in the frame in addition to the standard data and forms the PROFIsafe frame.
Existing solutions can be expanded without needing to change cabling.
PROFIsafe prevents errors such as address corruption, loss, delay, etc. when transferring
messages by consecutively numbering the PROFIsafe data, time monitoring, authenticity
monitoring using passwords and optimized CRC protection.
●PROFIenergy
With the PROFIenergy profile, individual consumers or entire production units can be
turned off and on. This is coordinated centrally by a higher-level controller; networking is
via PROFINET. During long pauses, this allows as much energy as possible to be saved.
Plant sections that are turned off for a short time contribute to the uniform distribution of
energy and optimum use of energy.
It is also possible to read out measurement variables relating to consumption.
PROFIenergy is defined so that the necessary function blocks can be included easily in
existing automation solutions.
Implementation of PROFINET in SIMATIC
PROFINET is implemented in the SIMATIC products as follows:
●Communication between field devices is implemented in SIMATIC with PROFINET IO.
●Installation technology and network components are available under the SIMATIC NET
brand name.
●For remote maintenance and network diagnostics, the tried and tested IT standards from
the office world are used (e.g. SNMP = Simple Network Management Protocol for
network parameter assignment and diagnostics).

Documentation of PROFINET on the Internet
Numerous publications on the topic of PROFINET can be found at the Internet address
(https://www.profibus.com) of PROFIBUS & PROFINET (PI) International.
You will find further information on the Internet (https://www.siemens.com/profinet).
1.2.2.2 PROFINET IO
What is PROFINET IO?
Within the framework of PROFINET, PROFINET IO is a communications concept for the
implementation of modular, distributed applications.
With PROFINET IO, you create automation solutions in the same way as familiar from
PROFIBUS DP.
Implementation of PROFINET IO is implemented by the PROFINET standard for
programmable controllers (IEC 61158-x-10).
The STEP 7 engineering tool supports you when setting up and configuring an automation
solution.
In STEP 7, you therefore have the same application view regardless of whether you are
configuring PROFINET devices or PROFIBUS devices. The user program looks the same for
PROFINET IO and PROFIBUS DP. The same function blocks and system status lists are
used (were expanded for PN IO).
1.2.3 SIMATIC NET
SIMATIC NET in the automation world
SIMATIC NET is the product name for networks and network components. The network
solutions of SIMATIC NET are an integral component of Totally Integrated Automation (TIA).
With TIA, Siemens is the only manufacturer that offers a consistent basis for the realization
of customer-specific automation solutions.
The data can be exchanged between all levels - from the field level to the production
management level right through to the enterprise management level.
The SIMATIC NET network components have uniform system interfaces and are compatible.
In addition to the previous wired solutions, wireless communication is gaining ground in
industry. SIMATIC NET offers products for company-wide data transmission over local
networks, intranet, Internet or wireless networks.
