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
● Network topologies adapted to a particular plant with the emphasis on linear (bus),
redundant network structures.
The components must meet the following requirements:
● Equipment designed for industry, for example signaling contacts, protected cables and
connectors
● Capability of withstanding extreme environmental conditions, for example extreme
temperatures, vibration, dust, dampness, electromagnetic interference.
PROFINET
PROFINET is the name of the standard for Industrial Ethernet (IEC 61158/61784) developed
and maintained by the PROFIBUS user organization.
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
● Demanding requirements for safety, reliability and availability.
This world is in stark contrast to an office environment where high data throughput and largearea networking are the main objectives. 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 wide range of network components grouped under the motto
"Totally Integrated Automation" to reflect the modern fully integrated implementation of
automation solutions. PROFINET is the protocol used by SIMATIC NET components within
the framework of Industrial Ethernet.

Basics of Industrial Ethernet
Properties of Industrial Ethernet
Industrial Ethernet is a powerful communication medium complying with the international
standard IEEE 802.3 (Ethernet) and 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
– FastConnect cabling system with RJ-45 and M12 technology
– Assembly of POF, PCF and MM fiber-optic cable
● High transmission performance even with large numbers of nodes thanks to the end-toend availability of components with 100 Mbps transmission rates complying with Fast
Ethernet and 1000 Mbps with Gigabit Ethernet.
● Ethernet with real-time capability that meets high requirements for the reaction time.
● 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 with scalable performance available when
necessary with switching technology.
● Networking of different areas of application such as office and production
● "Rapid Roaming" in Industrial Wireless LAN (IWLAN) for extremely fast handover of
mobile nodes between different access points and therefore fast cyclic data
communication (iPCF and iPCF-MC).
● Communication throughout the enterprise with the options of linking over WAN (Wide
Area Network, for example DSL or mobile wireless).
● Precise time stamping of events in the entire system with plant-wide timekeeping

1.2 Industrial Ethernet
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
cable.
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 1000 Mbps, 1Gbps or 10 Gbps.
The relevant standards are as follows:
● IEEE 802.3z for transfer via glass fiber
● IEEE 802.3ab for electrical cable.
The increase in the transmission speed is achieved not only by adaptation of the protocol but
also by using category "5e" or "6" 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.
● Deterministic; put simply:
The same conditions always lead to the same results and there are no undefined
statuses.

Basics of PROFINET
What is PROFINET?
PROFINET is the innovative and 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 realtime response (Page 19)".

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.
● Communication between the controllers as components in distributed systems is
implemented in SIMATIC by PROFINET CBA (Component-Based Automation).

● 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
(http://www.profibus.com) of PROFIBUS International.

PROFINET IO and PROFINET CBA
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).
What is PROFINET CBA?
Within the framework of PROFINET, PROFINET CBA (Component-Based Automation) is an
automation concept concentrating on the following aspects:
● Implementation of modular applications
● Machine-machine communication
With PROFINET CBA, you create a distributed automation solution based on off-the-shelf
components and partial solutions. This concept meets the requirements for greater
modularization in mechanical engineering and plant engineering with extensive distribution of
intelligent processing.
With Component-Based Automation, you implement complete technological modules as
standardized components that can be used in large plants.
You create the modular, intelligent components in PROFINET CBA in an engineering tool
that may differ from device manufacturer to device manufacturer. Components made up of
SIMATIC devices are created with STEP 7 and interconnect these with the SIMATIC iMAP
tool.

PROFINET CBA. From a PROFINET IO system, a PROFINET component is created, for
example in STEP 7. With SIMATIC iMAP you can configure plants made up of several such
components. The communications connections between the devices are simply configured
graphically as interconnection lines.
The following figure shows a distributed automation solution with several components that

Basics of communication with Industrial Ethernet
1.2 Industrial Ethernet
Non real-time communication (NRT communication)
NRT communication is non-time -critical communication and corresponds to the
communication of Industrial Ethernet with the protocol family TCP/IP. Everything that is
transferred using Industrial Ethernet can also be transferred via PROFINET, for example
HTTP, TCP, UDP, SNMP, ARP.
Real-time communication (RT communication)
Real time means that a system processes external events within a specific time. If the
reaction is predictable, this is known as a deterministic system.
A high data rate alone is no guarantee for real-time response, since delays are possible at
"bottlenecks" in the network. Instead, the network protocol must ensure that time critical
frames are given preferential treatment.
RT communication is suitable for transfer of alarms and cyclic data. Special switches must
be used here. All SIMATIC NET switches are suitable for this. There is, however, not yet any
need for particular communication planning in the form of a special configuration.
In RT communication the cyclic data are transferred between the IO controller and IO device,
however, without the "best possible synchronicity".
Unsynchronized IO devices automatically exchange data using RT communication.
Isochronous real-time communication (IRT communication)
In PROFINET with IRT, communication over Ethernet is divided into individual cycles. Each
cycle consists of two phases, an IRT channel reserved for extremely time-critical data, and
an "open channel", within which RT and non-time critical frames can be sent.
This allows time-critical and uncritical data to be sent on the same connection. At the same
time, however, a certain data rate (and therefore a transmission time) is reserved for the
critical data and real-time capability can therefore be guaranteed.
Properties of isochronous real time
With the implementation of the data transfer procedure IRT in Ethernet controllers, the
ERTEC ASICs (Enhanced Real-Time Ethernet Controller), update times of 250 µs and a
jitter accuracy of the transmit clock of less than 1 µs can be achieved.
In PROFINET V2.3, the methods fast forwarding, dynamic frame packing and fragmentation
were implemented. With these methods, update times of up to 31.25 µs can be reached.
IRT is used in areas with particularly stringent requirements for response times that cannot
be exceeded. This is the case, for example, for motion control applications, which require
reaction and update times in the range of a few milliseconds. Special switches must be used
here. In SIMATIC NET, the suitable switches have "IRT" in their names.

The binary representation of the 4 subnet mask decimal numbers must contain a series of
consecutive 1s from the left and a series of consecutive 0s from the right.
The 1s specify the network number within the IP address. The 0s specify the host address
within the IP address.

Incorrect value:
255.255.1.0 D = 1111 1111.1111 1111.0000 0001.0000 0000 B
Relationship between the IP address and subnet mask
The first decimal number of the IP address (from the left) determines the structure of the
subnet mask with regard to the number of "1" values (binary) as follows (where "x" is the
host address):
First decimal number of the IP address
Subnet mask
0 to 127
255.x.x.x
128 to 191
255.255.x.x
192 to 223
255.255.255.x
Classless Inter-Domain Routing (CIDR)
CIDR is a method that groups several IP addresses into an address range by representing
an IP address combined with its subnet mask. To do this, a suffix is appended to the IP
address that specifies the number of bits of the network mask set to 1. Using the CIDR
notation, routing tables can be reduced in size and the available address ranges put to better
use.
Example:
IP address 192.168.0.0 with subnet mask 255.255.255.0
The network part of the address covers 3 x 8 bits in binary representation; in other words 24
bits.
This results in the CIDR notation 192.168.0.0/24.
The host part covers 1 x 8 bits in binary notation. This results in an address range of 2 to the
power 8, in other words 256 possible addresses.
Value range for gateway address
The address consists of four decimal numbers taken from the range 0 to 255, each number
being separated by a period; example: 141.80.0.1
Range of values for IP address and gateway address
The only parts of the IP address and network transition address that may differ are those in
which "0" appears in the subnet mask.

Example:
You have entered the following: 255.255.255.0 for the subnet mask; 141.30.0.5 for the IP
address and 141.30.128.0 for the gateway address. Only the fourth decimal number of the IP
address and gateway address may be different. In the example, however, the 3rd position is
different.
You must, therefore, change one of the following in the example:
The subnet mask to: 255.255.0.0 or
the IP address to 141.30.128.5 or
the gateway address to: 141.30.0.0
1.3.2.2
Structure of an IPv6 address
IPv6 address format - notation
IPv6 addresses consist of 8 fields each with four-character hexadecimal numbers (128 bits in
total). The fields are separated by a colon.
Example:
fd00:0000:0000:ffff:02d1:7d01:0000:8f21
Rules / simplifications:
● If one or more fields have the value 0, a shortened notation is possible.
The address fd00:0000:0000:ffff:02d1:7d01:0000:8f21 can also be shortened and written
as follows:
fd00::ffff:02d1:7d01:0000:8f21
To ensure uniqueness, this shortened form can only be used once within the entire
address.
● Leading zeros within a field can be omitted.
The address fd00:0000:0000:ffff:02d1:7d01:0000:8f21 can also be shortened and written
as follows:
fd00::ffff:2d1:7d01:0000:8f21
● Decimal notation with periods
The last 2 fields or 4 bytes can be written in the normal decimal notation with periods.
Example: The IPv6 address fd00::ffff.125.1.0.1 is equivalent to fd00::ffff:7d01:1

address of the destination exists.
Determination of the next hop - uses an algorithm to determine the IP address of a packet recipient located one hop
over the local link. The next hop can be a router or destination node.
Neighbor unreachability detection - helps nodes to determine
whether a neighbor node is still reachable. With routers and
hosts the address resolution can be repeated.
Detection of duplicate addresses – Allows a node to determine whether an address wanted by a node is already being
used by another node.
Diversion - allows a router to inform a host about a node in
the first hop via which a certain destination can be reached
better.

Management functions
SNMP
With the aid of the Simple Network Management Protocol (SNMP), you can monitor and
control the network elements (e.g. routers, servers, switches, printers, computers etc.) from
a central station. SNMP controls the communication between the monitored devices and the
monitoring station.
SNMPv1 and SNMPv2c
In versions v1 and v2c, SNMP has no security mechanisms. Each user in the network can
access data and also change parameter assignments using suitable software.
For the simple control of access rights without security aspects, community strings are used.
The community string is transferred along with the query. If the community string is correct,
the SNMP agent responds and sends the requested data. If the community string is not
correct, the SNMP agent discards the query.
SNMP data packets are not encrypted and can easily be read by others. The monitoring is
handled by "SNMP agents". SNMP agents are programs that execute on the devices to be
monitored and send SNMP data packets to an SNMP manager. The data is described in a
Management Information Base (MIB). The RFC 1213 document contains the definition of the
MIB-2 important for SNMP.
SNMP v3
Compared with the previous versions SNMP v1 and SNMP v2c, SNMP v3 introduces a
comprehensive security concept.
SNMP v3 supports
● Fully encrypted user authentication
● Encryption of the entire data traffic
● Access control of the MIB objects at the user/group level

Note
To further improve security, separate the administration network from the remaining
network as a separate unit if this is possible.
DynDNS
Dynamic Domain Name Servers (DynDNS) allow applications to be reached on the Internet
using a host name, for example myHost.org. Even if these applications do not have a fixed
IP address and the host name is not registered. If, for example, you register a SCALANCE
device for a DynDNS service, you can reach the device from the external network using a
host name, for example SCALANCE.dyndns.org.
1.3.5
Power over Ethernet
Power supply via the Ethernet cable
In the IEEE 802.3af/at standard, the option of supplying devices with direct current was
standardized. To achieve this, either the wire pairs of the network cable not used for data
transfer are used or the supply voltage is modulated onto the data lines (phantom power).
The supply voltage and the load specified in the 802.3af standard differs from the 802.3at
standard. The standards are abbreviated as PoE or PoE plus.
The following voltages or power are available:

– 100BASE-TX
In both cases, a 4-pair Ethernet cable is required since the contacts 4-5 and 7-8 are used
for power supply. All CAT 5 and CAT 5e cables meet these requirements.
Safety circuit to protect devices without PoE capability
To ensure that you do not damage any devices without PoE capability by using PoE or PoE
plus, a safety circuit is defined:
● If the PSE identifies a resistance of 25 kΩ between the power wires, the end device is
capable of PoE. The power voltage is raised slowly by the PSE.
● If the PSE detects other resistance values, the power is not increased or it is turned off.
Classification of the power sourcing equipment (PSE)
● Endspan
With endspan, the power is supplied via a switch that can reach a device over an
Ethernet cable. The switch must be capable of PoE. The two modes can be used in
parallel if the devices with PoE capability support this.
● Midspan
Midspan is used when the switch is not PoE-compliant. The power is supplied by an
additional device between the switch and end device. In this case, only data rates of
10/100 Mbps can be achieved because the power is supplied on redundant wires.
SIMATIC NET devices with PoE
Some devices of the SCALANCE W und SCALANCE X series are capable of PoE. The
abbreviations in brackets describe the way in which PoE is supported.
● PSE stands for Power Source Equipment, the device can take over the power supply.

Fault tolerance and redundancy
Overview
Fault-tolerant systems are designed to reduce production downtime. Availability can be
enhanced, for example, by means of component redundancy. Communication systems are
thus extended to automation systems.
Redundant systems in industrial Ethernet are characterized by the multiple (redundant)
presence of important automation components. When a redundant component fails,
processing of the program is not interrupted.
Redundancy is achieved by duplicating the part components such as CPU, network, CP, etc.
Monitoring and synchronization mechanisms ensure that if the active redundant connection
path fails, the previously passive (redundant) connection path takes over the communication
automatically. The connection itself remains established.

Redundant network
The following graphic illustrates the principle of the high availability based on the example of
a redundant network. The entire cable topology exists twice, in the following graphic
represented as "LAN A2 and "LAN B". The connected components must be suitable for
redundant operation which is the case with the SIMATIC NET modules with "RNA" in the
name (abbreviation for "Redundant Network Access). Every component is connected to both
networks and all data is transported at the same time via both networks. If one of the
transmission paths is interrupted, the communication via the parallel network is unaffected.

Access Methods
Switching mechanisms
PROFINET is based on Fast Ethernet with 100 Mbps or Gigabit Ethernet with 1000 Mbps
and switch mechanisms and has further developed this technology.
Compared with other methods this has the advantage that each node can send at any time
since it always has a free point-to-point connection to the next switch. The connection is
bidirectional. The nodes can send and receive in both directions at the same time (full
duplex).
Switches in SIMATIC meet the real-time properties in PROFINET with two transmission
techniques "Store and Forward" and "Cut through".
Industrial Ethernet
38
System Manual, 05/2016, C79000-G8976-C242-08
Basics of communication with Industrial Ethernet
1.3 Technologies of Industrial Ethernet
"Store and Forward"
With the transmission technique "Store and Forward", the device stores the frames and then
enters them in a waiting queue. The frames are now forwarded selectively to the port that
has access to the addressed node.
If the device supports the international standard IEEE 802.1Q the frames are sorted into
different queues according to their priority. First, the frames with the highest priority are
processed.
Advantage
With the transmission technique "Store and Forward", the frames are checked that they are
correct and valid. This prevents bad or damaged frames being distributed through the
network.
Cut through
With the transmission technique "Cut Through" the entire frame is not stored temporarily in a
buffer but forwarded directly to the destination port as soon as the first 6 bytes (destination
address) have been read and the destination port identified.
The times that the data packet requires to pass through the switch are minimal and not
dependent on the frame length. The data is only stored temporarily using the store and
forward mechanism according to its priority when the section between the target part and the
port of the next switch is in use.
With PROFINET switches Cut Through is implemented by using ERTEC ASICs, for example
in the IRT switches of SCALANCE.

Layer 3 functions
Introduction
The term layer 3 function effectively means routing. The term routing describes the
specification of paths (routes) for communication between different networks. This means:
how a data packet travels from subnet A to subnet B.
Devices with layer 3 functionality are also known as layer 3 switches. Layer 3 switches can
operate both at OSI layer 2 (MAC address) or at OSI layer 3 (IP address).
A layer 3 switch can assign various subnets to its ports, e.g. subnet A and subnet B. This
allows large networks to be divided into smaller subnets with their own address space.
Reasons for dividing into subnets include, for example, the separation of the Ethernet
network to reduce data traffic, the separation of sensitive areas from the main network and
the division of the network into logical workgroups.
The data packets are forwarded either using the Cut Through or the Store and
Forwardtechnique.
Industrial Ethernet

39
Basics of communication with Industrial Ethernet
1.3 Technologies of Industrial Ethernet
Static routing
In static routing, the paths that a data packet can take are entered permanently (statically) in
the routing table.
Dynamic routing
With dynamic routing, the paths that a data packet can take are identified dynamically
between the routers involved, see also "Dynamic routing with OSPF".
Router redundancy with VRRP
With the aid of the Virtual Router Redundancy Protocol the failure of a router in a network
can be countered. VRRP, for example, provides the option of setting up device redundancy
for the default gateway of the end devices.
Several physical routers in a network segment are grouped together to form a logical group.
A virtual MAC and IP address then apply for this area. One router of this group is made
master. This master adopts the virtual MAC and IP address of the area. The other routers of
this group are then backup routers. If the master fails, another router from the group takes
over the virtual MAC and IP address and the tasks of the failed router. This means that the
network area affected can continue to communicate with the outside world. The network
segment can no longer be reached only after the failure of the last router in the group. Due to
the backup router adopting the virtual MAC and IP address, no other actions are necessary
for the other routers in the area of the segment. Routing tables or the ARP cache do not
need to be updated. This minimizes the consequences of device failure.
Dynamic routing with OSPFv2
Open Short Path First is a routing protocol developed by the Internet Engineering Task
Force (IETF). With OSPF, CIDR (Classless Inter-Domain Routing) and VLSM (Variable
Length Subnet Mask) are also implemented.
The routers setup a, neighborhood database (LSDB = Link State DataBase). The
neighborhood database is the heart of OSPF and contains information on the topology of the
network.
To set up the neighborhood database, the router needs to learn its direct neighbor routers.
To do this, the router sends out Hello packets following initialization. The neighbor routers
exchange packets (LSA - Link State Advertisements) that describe the content of their
database. When the exchange of information with the neighbor router is completed the
neighborhood database of the neighbor routers is the same.
The neighborhood database is used to calculate routes based on the SPF algorithm
(Shortest Path First). The algorithm creates a hierarchical tree structure (Shortest Path Tree)
in which each destination with the shortest (loop-free) and lowest cost route is entered. The
algorithm uses the costs of the path as a metric. What is used to calculate the costs is not
defined. The costs can be, for example, the data rate of the connection or the reliability of the
connection. The entries from the tree are adopted in the routing table. If several routes with
the same costs exist for a destination, the data is transferred via different routes to achieve
load distribution.
The routers continuously test the state of the connection between themselves by exchanging
Hello packets. If a connection is disrupted, the router sends a message to its neighbor
Industrial Ethernet

System Manual, 05/2016, C79000-G8976-C242-08
Basics of communication with Industrial Ethernet
1.3 Technologies of Industrial Ethernet
router. The neighbor router updates its database and sends the message to its neighbor
router and so on until the modification has passed through the entire network.
To limit the size of the routing table, OSPF can divide a network (autonomous system) into
hierarchical areas. Each area has its own neighborhood database and its own shortest path
tree.
By dividing into areas, if there is change in the topology, the entire network is not loaded with
messages so that OSPF manages with relatively low overheads.
If several neighbor routers can be reached in an area, the designated router (DR) and the
backup designated router (BDR) are identified based on Hello packets. By identifying the
designated router, the topology is simplified. The designated router then sends the message.
To send a frame from area 1 to area 2, the frame is first sent to the area border router (ABR)
of area 1. The ABR connects its area to the backbone area. The ABR of area 1 sends the
frame to the router in the backbone area that forwards the frame to the ABR of area 2. The
backbone area (area 0) is used to distribute routing information about the reachability of
areas between area border routers. A frame is sent to another AS via an Autonomous
System Area Border Router (ASBR). On the ASBR, one interface is connected to another
AS, for example an AS that uses the RIP routing protocol.
With OSPF, messages can be authenticated. Only trustworthy routers can take part in the
routing with OSPF.
1.3.9
EtherNet/IP
Introduction
EtherNet/IP is an Ethernet protocol that meets real-time requirements within certain limits.
EtherNet/IP can be implemented with standard Ethernet hardware, however the restrictions
in terms of the cycle time in Ethernet also apply.
Technical basics
Time-critical IO communication is sent in EtherNet/IP as multicast using UDP, which
however results in a high network load. This can be eliminated in part by using managed
switches with "IGMP snooping". In addition to this, the field devices need to provide a high
computing power because the IP stack is used for IO data. Nodes are addressed using the
IP address and some standard technologies such as DHCP and BootP are supported by
EtherNet/IP. For time synchronization, the Precision Time Protocol according to IEEE 1588
is used.

1.4 Switches and switched LANs
1.4
Switches and switched LANs
If a network needs to be divided into several (logical and physical) subunits, switches are
used at the connection points of the network sections.
Switches are active components that can receive and send at several ports independently.
There are equipped with intelligence that allows them to forward received messages only via
the port connected to the segment in which the actual addressee is located. This can be
connected directly to the port or via a further switch.
Since all direct connections are point-to-point and since the medium used allows full duplex
communication, it is no longer possible for collisions to occur.
Switched connection paths: "Shared LANs" and "Switched LANs"
"Shared LANs" are networks on which a message being transmitted blocks the network for
all other nodes; in other words, there can only be one sender at any one time. A wireless
network is a simple example of such a shared LAN.
"Switched LANs" are set up using switches and are characterized by the connection paths
for each data packet being switched based on the target address. Different data packets can
be in transit in the network at the same time on different connection paths. The data packets
only run through segments that lead to the recipient. All the SCALANCE X products belong
to the products that operate according to the switching method and therefore create
"switched LANs".
Functions of switches
Essentially, switches have the following functions:
● Connection of subnetworks
Switches connect several collision domains. This allows extensive networks to be set up
with numerous nodes and simplifies network expansion. The distance covered depends
on the FO interfaces or electrical interfaces used in the devices. You will find information
on the achievable distances in the system manual Industrial Ethernet/PROFINET Passive
Network Components.
● Separating load
By filtering the data traffic based on the Ethernet (MAC) addresses, local data traffic
remains local. The data is distributed to all ports/network nodes using the direct switching
method. Only data intended for nodes in other sublets is switched from the input port to
the appropriate output port of the switch. To make this possible, a table assigning
Ethernet (MAC) addresses to output ports is created by the switch in a "teach-in" mode.
● Limiting errors to the affected subnetwork.
By checking the validity of a data packet on the basis of the checksum which each data
packet contains, the switch ensures that bad data packets are not transported further.
Collisions in one network segment are not passed on to other segments.

Basics of communication with Industrial Ethernet
1.4 Switches and switched LANs
Advantages of switched LANs
The advantages of such switched LANs are:
● Good performance (since the messages only block the sections of cable actually between
the sender and receiver),
● Avoidance of data collisions because the sender does not block the entire network
● High availability particularly in topologies that include redundancy,
If a connection path is blocked in a redundant topology (due to a cable break or
component failure), switches can still redirect the messages over an alternative path and
maintain communication. A network with a ring topology (see below) is a classic example
of using switches in this way.
● Option of forming subnets and network segments,
● Simple rules for network configuration,
● Simple, expansion is possible without affecting the existing network.
Application example: Redundant ring
Using an IE Switch X-300 as the redundancy manager in a ring with a redundancy manager
(Page 65) provides greater availability. If there is an interruption on the connection between
these switches, the IE switch used as redundancy manager acts like a switch and in a very
short time creates a line (bus) from the ring. As a result, a functional, end-to-end structure is
restored.

Wireless LAN
1.5.1
What is wireless LAN?
WLAN
A wireless LAN or WLAN is a "Wireless Local Area Network"; in other words a network
based on wireless covering a limited area. WLAN is based on the IEEE 802.11 standard.
IWLAN
The Industrial Wireless LAN (IWLAN) technology is a further development of WLAN for
industrial applications. In contrast to WLAN, IWLAN provides predictable data traffic
(deterministic) and defines response times for high-speed applications. This makes it
possible to transfer process-critical data, for example alarms. By implementing a wireless
solution, you can replace hard-wired connections that are subject to natural wear and tear,
for example contact conductors. Use cases for wireless solutions such as overhead
monorails, driverless transport systems or user-specific operator control and maintenance
devices.
To protect data traffic, rugged and immune modules are used on the one hand and on the
other hand the data is encrypted.
1.5.2
Differences between wireless LAN and wired networks
Cable as opposed to radio waves
The use of cables and wires for communication has certain advantages because this makes
an exclusive medium available:
The transmission properties in a hard-wired network are defined and remain the same as
long as the cable, routers or similar are not replaced. Since a wired network is limited in
locality, it is possible to recognize at any time which nodes are connected to a LAN (Local
Area Network) and which are not.
On the other hand, the effort and cost of cabling increases with the number of nodes and, at
the same time, the potential for broken cables and other hardware faults. Finally,
communication with freely moving nodes using wired methods is practicable only in
exceptional situations. Wireless links also allow sections to be covered that would be
problematic using cables, for example roads, water.
In these situations, wireless networks are an advantage. The advantage is in the mobility of
the individual components and their flexible use.
"Wireless" as such is a limited resource. Due to its nature as a "shared medium" it is not
possible to increase the capacity as would be possible, for example, by simply laying more
cable. This means that with the increasing number of nodes, the effective data rate that can
be reached by the individual nodes sinks.

1.5 Wireless LAN
Complexity of the RF field
Radio waves propagate through space are and deflected by obstacles or weakened when
passing through. This means that an RF field with a complex structure is created that
changes when the obstacles move. The area illuminated by one or more transmitters is not
sharply defined. There is also no clear delineation of the RF field and the transmission
characteristics of the individual nodes in the wireless network fluctuate depending on their
position. Lastly, it is also practically impossible to detect a "silent listener" in a wireless
network.
These properties need to be taken into account in terms of the reliability of the wireless link
and the security of a network against eavesdropping and immunity to interference. Wireless
networks are, however, just as reliable, secure and resilient as hard-wired networks if trained
employees are deployed who are aware of the particular demands of a wireless network.
1.5.3
Preferred areas of application for WLANs
Preferred areas of application
In many environments, their special qualities make wireless networks the preferred, and in
some cases only practical medium.
These include:
● Connection of mobile nodes both among themselves and with stationary nodes,
● Connection of mobile nodes with wired networks (Ethernet etc.),
● Contact with rotating nodes (cranes, carousels, ...),
● Connection of nodes with restricted mobility (monorail suspension tracks, high-bay
storage racks, ...), as a replacement for slip contacts or trailing cables,
● Establishing wireless bridges between physically separate wired subnets (different
buildings, across streets, over water, ...),
● Communication with nodes in inaccessible areas.

The standards of the "IEEE 802.11" series
Standardization of WLANs
IEEE
The acronym "IEEE" stands for the Institute of Electrical and Electronics Engineers, an
organization that has taken on the task of developing, publishing and promoting electronic
and electrotechnical standards and that can be compared in some ways with DIN.

The IEEE 802.11 group
Under the project number "802", a number of working groups were given the task of
developing standards for setting up and operating networks. A known example is the "802.3"
working group that is concerned with the standards for Ethernet connections.
The "802.11" working group concentrates on the specification for wireless LAN, the IEEE
802.11 standard. The most important expansions of the standard are "802.11 a/h",
"802.11 b/g" and "802.11n".

streaming),
● 802.11 "i": Replaces the no longer tenable WEP encryption mechanism with WPA or
WPA2.
● 802.11 "p": Introduces WLAN technology for motor vehicles with which an interface for
applications involving intelligent traffic systems is created.
1.5.5
IEEE 802.11n
The standard IEEE 802.11n is an expansion of the 802.11 standard and was approved in
2009.
Previous Standards worked either in the 2.4 GHz frequency band (IEEE 802.11g /b) or in the
5 GHz frequency band (IEEE 802.11a ). IEEE 802.11n can operate in both frequency band.
In the IEEE 802.11n standard, there are mechanisms implemented in PHY and MAC layers
that increase the data throughput and improve the wireless coverage.
With SCALANCE W700 devices, a data throughput up to 450 Mbps (gross) is possible due
to support of the following mechanisms. This maximum data throughput is possible only if
the mechanisms are used at the same time.

Basics of communication with Industrial Ethernet
1.5 Wireless LAN
MIMO antenna technology
MIMO (Multiple Input - Multiple Output) is based on an intelligent multiple antenna system.
The transmitter and the receiver have several spatially separate antennas. The spatially
separate antennas transmit the data streams at the same time. Up to four data streams are
possible. The data streams are transmitted over spatially separate paths and return over
different paths due to diffraction, refraction, fading and reflection (multipath propagation).
The multipath propagation means that at the point of reception a complex, space- and timedependent pattern results as a total signal made up of the individual signals sent. MIMO
uses this unique pattern by detecting the spatial position of characteristic signals. Here, each
spatial position is different from the neighboring position. By characterizing the individual
senders, the recipient is capable of separating several signals from each other.
Maximum ratio combining (MRC)
In a multiple antenna system, the wireless signals are received by the individual antennas
and combined to form one signal. The MRC method is used to combine the wireless signals.
The MRC method weights the wireless signals according to their signal-to-noise ratio and
combines the wireless signals to form one signal. The signal-to-noise ratio is improved and
the error rate is reduced.

Basics of communication with Industrial Ethernet
1.5 Wireless LAN
Spatial mutliplexing
With spatial multiplexing, the data to be transmitted can be distributed over several
transmitting antennas according to specified rules. The devices currently use a maximum of
three antennas. The data stream is therefore divided among three transmitting antennas. As
a result different data streams are transferred at the same time over three transmission
paths. This allows the data throughput to be greatly increased. The spatially differing data
streams are known as spatial streams. The number of spatial streams specified for an
IWLAN (Industrial WLAN) is a measure of the transmission rate. Per data stream, a
maximum of 150 Mbps is transferred according to IEEE 802.11n. With four antennas and
four data streams this results in a maximum of 600 Mbps and with three antennas and three
data streams 450 Mbps. Ideally the net data throughput is then over 200 Mbps which
compared with traditional WLAN standards means an almost ten times higher transmission
rate.

1.5 Wireless LAN
Channel bonding
With IEEE 802.11n, data can be transferred via two directly neighboring channels. The two
20 MHz channels are put together to form one channel with 40 MHz. This allows the channel
bandwidth to be doubled and the data throughput to be increased.
To be able to use channel bonding, the recipient must support 40 MHz transmissions. If the
recipient does not support 40 MHz transmissions, the band is automatically reduced to 20
MHz. This means that an IEEE 802.11 access point can communicate with 802.11a/b/g/h
and 802.11n products within the network.
Frame aggregation
With IEEE 802.11n, it is possible to group together individual data packets to form a single
larger packet; this is known as frame aggregation. There are two types of frame aggregation:
Aggregated MAC Protocol Data Unit (A-MPDU) and Aggregated MAC Service Data Unit (AMSDU).
The frame aggregation reduces the packet overheads. Frame aggregation can only be used
if the individual data packets are intended for the same receiving station (client).
Accelerated guard interval
The guard interval prevents different transmissions being mixed together. In
telecommunications, the guard interval is also as intersymbol interference (ISI).
The guard interval of IEEE 802.11a /b/g is 800 ns. IEEE 802.11n can use the reduced guard
interval of 400 ns.

Encryption and data security
WPA2 and AES ("Advanced Encryption Standard")
WPA2 is seen as a standard today and differs from WPA essentially in the encryption
method: The weaknesses identified in WPA no longer exist in the AES method used in
WPA2.
When a "sensible" password is selected that is adequately long and cannot be guessed at,
AES encrypted messages count as being safe from eavesdropping according to today's
state of the art.
WPA ("Wi-Fi Protected Access")
WPA is the further development of WEP. Apart from technical modifications in the actual
encryption algorithm, the protocol was also adapted:
● Passwords for network access (authentication) are stored on a central server
("RADIUS"),
● The key for frame transmission changes dynamically making statistical attacks more
difficult,
● The MAC address is worked into the key (in other words, unique hardware identification)
of the sender making it more difficult to falsify the sender of the message.
WEP ("Wired Equivalent Privacy")
WEP is the oldest and at the same time the least secure encryption method with which
WLAN transmission is protected against unauthorized intruders according to the 802.11
standard.
With this method, a user password is used as a key from which a series of pseudo random
numbers is generated. Each character of the frame to be transmitted is then encoded with
next number of this series and decoded at the receiver.
Today, WEP is considered insufficiently secure.
EAP ("Extensible Authentication Protocol")
The acronym EAP covers a wide framework of different authentication mechanisms for
network access. In other words, EAP is not an authentication method itself but describes the
mechanism according to which the client and server can agree on a method.

1.5.7
Avoiding collisions in wireless networks
CSMA/CA with RTS/CTS
Ethernet uses the bus access method CSMA/CD. This acronym stands for Carrier Sense
Multiple Access with Collision Detection. After the node wanting to send has listened to the
line and identified it as being free (Carrier Sense CS), the data is sent.
While sending, the sending node can recognize a collision (Collision Detection, CD) with
other nodes sending at the same time (Multiple Access, MA) based on a disturbed level and
end the transmission.
This mechanism is used in just the same way in a wireless network apart from the fact that
collisions are deliberately avoided (Collision Avoidance, CA) to avoid reducing the net data
throughput unnecessarily. For this reason wireless LANs do not use the CSMA/CD method
with which collisions can occur and be detected, but rather the CSMA/CA method (Carrier
Sense Multiple Access with Collision Avoidance).
Instead of physically listening in on the channel, a communications protocol is used that
reserves the channel for a specific time. Before sending, a node checks whether or not the
medium is free.
In this so-called RTS/CTS method, the node wishing to transmit sends a short test signal
("Ready To Send" - RTS). The actual transmission begins after the recipient has replied to
this with "Clear To Send" (CTS). If a collision occurs, the retransmission follows after a
pause not selected at random but according to priority. With this strategy, communication
remains deterministic.

Structure of an IWLAN
Basic structure of a WLAN
WLANs do not have a physical topology like traditional wired networks. There are no
"buses", "rings" or "stars". Instead wireless networks are divided into cells.
Figure 1-4
Simple WLAN structure with two access points/wireless cells, RCoax cable and
IWLAN/PB Link PN IO gateway
Here, access points take over the role of switches. End nodes are connected to the network
by turning on so-called "clients". Larger networks can be achieved by setting up several
wireless cells each under the control of an access point. The connection between individual
cells is also via access points.
The access points function as their own wireless cell, between which the mobile nodes can
move. ("roaming")
Shared medium instead of switched medium
Wireless networks operate on the shared medium principle, in other words, only one node
can send at any one time. With the increasing number of nodes, the effective data rate that
can be reached by the individual nodes sinks.

Network structures
1.5.9.1
Infrastructure mode
In infrastructure mode, communication is handled via an access point. The nodes (clients)
need to log on with the access point and transmit on the channel specified by the access
point. The access point can manage the access rights of the clients and assign time slices to
them for communication so that real-time and deterministic communication is assured.
In the simplest case there is a group of clients in the wireless range of the access point.
Such a network is also known as a standalone network.
If the wireless range of an access point is inadequate either because the reachable distance
is too short or too few clients can be served, the network can be divided into several wireless
cells. All clients within the wireless cell are within the range of a central access point (AP).
The other clients only ever communicate with their access point and not directly with other
clients. By connecting external antennas, the range and coverage can be adapted to the
application. This means, for example that omnidirectional antennas in closed rooms can
achieve distances between 30 m and 100 m.
Standalone networks
Coordination by an access point:
This configuration does not require a server and the SCALANCE W access point does not
have a connection to a wired Ethernet. In this case, a central access point functions like a
switch receiving the frames from the individual nodes (clients) and forwarding them.

Multichannel configuration
If neighboring SCALANCE W access points use the same frequency channel, this can lead
to longer response times due to collisions that may occur. If the configuration shown in the
figure is implemented as a single-channel system, computers A and B cannot communicate
at the same time with the SCALANCE W access points in their cells.
If neighboring SCALANCE W access points are set up for different frequencies, this leads to
a considerable improvement in performance. As a result, neighboring cells each have their
own medium available and the delays resulting from time-offset transmission no longer
occur.
The channel spacing should be as large as possible; a practical value is 25 MHz. Even in a
multichannel configuration, all SCALANCE W access points can be configured with the same
network name.

WDS allows direct connections between SCALANCE W access points and or between
SCALANCE W and other WDS-compliant devices. These are used to create a wireless
backbone or to connect an individual SCALANCE W to a network that cannot be connected
directly to the cable infrastructure due to its location.

RWLAN allows a redundant, wireless connection between two SCALANCE W access points
with at least two WLAN interfaces. This is used to set up a redundant wireless backbone that
cannot be implemented as a wired network due to its location but nevertheless has high
demands in terms of availability.

Controller-based network structure
The IWLAN controller SCALANCE WLC711 allows central management of up to 64
controller-based access points. The IWLAN controller automatically recognizes new access
points, establishes the connection to them and manages and coordinates both access points
and clients. Due to the layer 3 architecture, access points are also managed that are located
in various layer 2 subnets. This function allows wireless expansion of an existing Ethernet
network without changes being necessary to the existing network structure.
With the IWLAN controller, the IWLAN Wireless infrastructure can be divided into logical,
service-based networks (Virtual Network Services). Different services, security requirements
and access criteria can be managed reliably and different user groups, for example
administrators, commissioning engineers or visitors can use the entire wireless network.
Various applications such as Voice-over-IP (VoIP), video and Internet access can use the
same infrastructure.

Redundant operation of two SCALANCE WLC711 devices increases the availability of the
wireless network. With the IWLAN controller, only the controller-based access points of the
SCALANCE W78xC series can be used.
Apart from central management and configuration of the wireless network, the IWLAN
controller WLC711 also allows logging of errors, monitoring of the wireless network and
documentation of network statistics.

Roaming
Clients moving between wireless cells: "Roaming"
To allow mobile nodes to be able to roam seamlessly from one access point to the next, the
individual wireless cells must overlap. This is transparent for the application. The access
points need to be interconnected via Industrial Ethernet or a wireless distribution system
(WDS).
The figure above shows how a moving node (in this case an automated guided vehicle
system) is handed over between two wireless cells: The client module runs regular scans of
the wireless signals on all the channels stipulated by the standard being used. The client
module then connects to the access point with the channel on which it finds the best
reception. If the limit between wireless cell 1 and wireless cell 2 is reached, the connection to
the access point of wireless cell 1 is terminated. From this time on, the access point of
wireless cell 2 is responsible for the client module.
The time required for the change (handover time) is in the order of 100 ms. A significant
reduction in handover times can be achieved with Rapid Roaming using the iPCF method
("industrial Point Coordination Function"). Both the access point and client must support
rapid roaming.
With some devices, the support of the iPCF method is released by the KEY-PLUG
"iFeatures" (example: SCALANCE W788-x), the SCALANCE W722-1 RJ45 supports this
method already when shipped.

Ad hoc networks
Ad hoc networks
In ad hoc mode, nodes communicate with each other directly (connection 4) without
involving an access point. The nodes access common resources (files or even devices, for
example printers) of the server (connections 1 to 3 in the figure). This is, of course, only
possible when the nodes are within the wireless range of the server or within each other's
range. Ad hoc networks can only be operated with the standard 802.11 "b".
As an alternative, wireless networks can be configured in "infrastructure mode".

Other wireless technologies
Industrial Wireless Control
Industrial wireless control is the connection of widely distributed process stations to one or
more central control systems. Various wireless methods are used for the communication
required for monitoring and control. This makes service possible on installations without fixed
telephone lines. An Internet access is also not necessary for the installation.
● GPRS
The General Packet Radio Service (GPRS) is a mobile wireless technology for packetswitched data transmission via GSM networks (Global system for mobile
communications). The GSM wireless channels are divided into eight time slots. One time
slot represents one transmission channel.
Packet-switched data transmission means that in contrast to line-switched data
transmission (as with GSM), no transmission channel is reserved permanently. The
sender divides the message into individual packets with additional information (packet
sequence, recipient address). With the aid of the GPRS system, the packets are
Industrial Ethernet
System Manual, 05/2016, C79000-G8976-C242-08
59
Basics of communication with Industrial Ethernet
1.5 Wireless LAN
forwarded through various time slots of the network. This makes it possible to use free
capacity. A GPRS session can also use several time slots at the same time. The recipient
then puts together the packets in the correct order. GPRS allows data exchange without
connection establishment and billing only according to the transferred amount of data.
Packet switching is made possible by IP technology. GPRS is used mainly for access in
IP-based networks, for example the Internet.
● EGPRS
The Enhanced General Packet Radio Service (EGPRS) is an expansion of GPRS and is
also known as Enhanced Data Rates for GSM Evolution (EDGE). EGPRS uses a
different modulation technique (8-PSK) from GPRS that is more efficient. This means that
a data rate up to four times higher can be achieved with EGPRS.
● UMTS
UMTS is the acronym for Universal Mobile Telecommunications System and is also
known as a mobile wireless standard of the third generation (3G). The maximum
transmission rate is 384 kbps.
● LTE
LTE stands for Long Term Evolution and is known as the 3.9G standard because it does
not completely implement the 4G specification of the ITU-T standard. It supports six
different bandwidths between 1.4 and 24 MHz and allows transmission rates up to 300
Mbps. The maximum data rate is only achieved when using 4x4 MIMO (multiple antenna
tehnology). The high transmission rate, for example, allows the transfer of language via
TCP/IP ("Voice over IP").
● LTE Advanced
LTE Advanced or also 4G is a protocol extension fro LTE. It provides transmission rates
up to 1000 Mbps and is downwards compatible to LTE. A further advantage is a higher
number of users that can be active at the same time.
WirelessHART
HART (Highway Addressable Remote Transducer) is the wireless connection of field devices
in process automation for advanced diagnostics.
Just like WLAN, WirelessHART also uses the ISM frequency band (2.4 GHz and with
maximum of 250 kbps) and automatically establishes meshed networks. The span of the
network is greater than the nominal wireless range of an individual node. The network
organizes itself by having all the connection information evaluated by a network manager.
With this information, redundant paths are made available automatically that can bridge the
failure of individual nodes. The main focus during the development of WirelessHART was
simple commissioning and maintenance of the self-organizing networks so that configuration
involved only minimum effort. The main area of application of WirelessHART is in the regular
transmission of small, non time critical-amounts of data at long intervals over relatively long
distances. Thanks to the low energy consumption, battery working lives of several years are
achieved.

Network topologies
2
Network topologies are oriented according to the requirements of the equipment to be
networked. The most common topologies include bus, star and ring structures. In practice,
plants usually consist of mixed structures. These can be implemented both with electrical
cables as well as with optical cables (fiber-optic cables).
Glass fiber-optic cables are used for long distances. For short distances, plastic fiber-optic
cables such as Polymer Optic Fiber (POF) or plastic covered glass fibers such as Polymer
Cladded Fiber (PCF) can be used.
2.1.2
Linear structure
Linear bus
The linear bus is the simplest network structure. It is characterized by a network backbone to
which the individual nodes are connected directly or over a branch (only one node is
permitted per branch).
● The advantage of the linear bus topology is its simple setup and low hardware
investment. It is suitable, for example, for networking of rigidly linked machines over a
wide area as found in assembly lines.
● The disadvantages of bus topologies are that the resources are not put to optimum use
and that there is no redundancy: A break on the cable at any point cannot be bridged.
Connecting the ends of the linear bus, on the other hand, creates a ring with which these
disadvantages can be avoided.

Network structures and network configuration
2.1 Network structures
A further restriction for networks with a linear bus structure is the physical arrangement of
the network nodes. Depending on their position, the backbone may need take long detours
which may, in turn, lead to problems with frame delay times. In a linear network topology, the
network components such as switches typically have only one or few connection points for
network nodes. Linear bus structures can also be created with devices with two integrated
network interfaces.
Setup
The bus structure can be implemented with SCALANCE X switches. Any TP ports can be
used to cascade and form a linear bus. The number of SCALANCE X switches that can be
cascaded depends on the response times of the applications operating over this linear bus.
● Electrical cables
There may be a maximum distance of 100 m between two of these devices.
● Optical cables
At 100 Mbps, the maximum distance between 2 devices can be as follows:
– Multimode, glass, up to max. 5 km
– LD: Single mode, glass up to max. 26 km
– LH+: Single mode, glass up to max. 70 km
At 1 Gbps, the maximum distance between 2 devices can be as follows:
– Multimode, glass, up to max. 750 m
– LD: Single mode, glass up to max. 10 km
– LH: Single mode, glass up to max. 40 km
– LH+: Single mode, glass up to max. 70 km
– ELH: Single mode, glass up to max. 120 km
2.1.3
Star structure
"Star"
The difference between the star topology and linear bus topology is that one switch functions
as the central node from which the spokes branch off to the individual nodes. The individual
nodes of the network therefore have separate point-to-point links with the active network
component (i.e. with the switch).
The immediate effect is that the messages only run via the spokes between sender and
recipient, in other words network performance improves significantly because several nodes
can communicate at the same time.
Depending on the requirements, in practice this may be a mixture of fiber-optic cables and
twisted pair cables on the individual transmission links. Typical applications are Ethernet
office networking or the networking of production cells in manufacturing with Industrial
Ethernet.

● The use of a switch optimizes data throughput in the network. Messages are transferred
only on the star segments between sender and recipient and the segments of the other
nodes remain unaffected by them. If a node fails, the communication between the other
network nodes remains intact.
● Compared with ring or linear bus structures, however, the investment in cabling increases
considerably due to the long distances back to the star center.
Typical use cases for star networks are switching cubicles, individual machines or
manufacturing cells.

With an FC TP standard cable, the end nodes can be located up to 100 m from the switch.

More complex network structures can be set up by using switches with a higher number of
ports. (In the example above, a SCALANCE X124 with 24 electrical ports.) In terms of the
numbers of nodes and the physical span of the network, this is practicable only up to a
certain limit.
If extensive networks need to be configured, the use of several switches and the resulting
sub-networks makes sense.

"Ring"
If the ends of a bus are connected via an additional connection, this results in a ring
structure. The switches connected together in a ring do not need to be interconnected only
with FO cables or only electrical cables. A mixed electrical-optical ring is also permitted.
A special redundancy mechanism ensures that the ring structure remains a logical bus in
normal situations and prevents frames from circulating. If a section of the ring fails, the
mechanism quickly makes a substitute path available in the ring: The message now travels
the long way round via the intact network section instead of over the direct interrupted path
and reaches its recipient via this detour. The network does not break down into two
segments.

Ring topology based on the example of Industrial Ethernet with glass fiber-optic cables and twisted pair cable
● The effects of a network component being disrupted are restricted to the failed
component and to the end devices connected to it. If a ring section is interrupted, for
example by a cable break, communication continues without any disruption.
The reconfiguration time is faster here than in the office world and meets the requirements of
the automation world.
Example: Structure of a redundant network with SCALANCE X switches
With the aid of a redundancy manager (RM), the two ends of a bus can be closed to form a
redundant ring. All the media converters SCALANCE X100/200/300/400 and X500 devices
can be used in this ring. The role of the RM can be handled by the SCALANCE
X200/X300/400 and X500 devices.
The RM monitors the line connected to it, if there is an interruption, it closes the ring and
restores a functioning bus configuration. A maximum of 50 of the SCALANCE X devices
mentioned above are permitted in an optical ring. Here, a reconfiguration time of less than
0.3 seconds is achieved. The RM mode on the SCALANCE X devices is configured in the
software. The maximum length of the fiber-optic cable between two devices is 3000 m for
multimode fiber and 200 km for single mode fiber. This means that a maximum of 150 km
(multimode) can be achieved for the entire optical ring consisting of 50 switches.

Redundant linking of network segments with electrical and FO components
General
SCALANCE X switches support not only ring redundancy within a ring but also redundant
linking of several rings or open network segments (linear bus). In the redundant link, two
rings are connected together over two Ethernet connections. This is achieved by configuring
a master/slave device pair in one ring so that the devices monitor each other and, in the
event of a fault, redirect the data traffic from the normally used master Ethernet connection
to the substitute (slave) Ethernet connection.

Standby redundancy
Figure 2-7
Example of redundant linking of two SCALANCE X-200 IRT rings
For a redundant link as shown in the figure, two devices must be configured as standby
redundancy switches within a network segment. Here, network segments are rings with a
redundancy manager (RM, in the example, the SCALANCE X202-2IRT switches). Instead of
rings, network segments might also be linear.
The two X202 devices connected in the configuration exchange data frames with each other
to synchronize their operating statuses (one device is master and the other slave). If there
are no problems, only the link from the master to the other network segment is active. If this
link fails (for example due to a link-down or a device failure), the slave activates its link as
long as the problem persists.

VLAN
Virtual Local Area Network
VLANs are virtual network segments in a physical network that are assigned to the nodes
during configuration. In contrast to the physical network, a VLAN is not spatially restricted.
This allows nodes to be put together in logical groups according to their function (VLAN
groups). VLANs can be set up without modifying the physical network.
SCALANCE X and SCALANCE W support port-based VLAN. For the parameter assignment
of the VLANs, a VLAN ID is assigned to the individual ports of a SCALANCE device.
Multicast and broadcast frames are possible only within the boundaries created by the
logical network structure; in other words, between ports with the same VLAN ID.
This segmentation not only reduces network load because broadcasts can be limited to a
practical number of end systems. VLANs also increase the security of a network since no
node can listen in any longer on the data traffic of other nodes unless they are a member of
this VLAN.
To identify which packet belongs to which VLAN, the Ethernet frame is expanded by 4 bytes
(VLAN tagging). This expansion includes not only the VLAN ID but also priority information.

Media redundancy in ring topologies
Structure of a ring topology
Nodes in a ring topology can be external switches and/or the integrated switches of
communications modules.
To set up a ring topology with media redundancy, you bring together the two free ends of a
linear bus topology in one device. Closing the linear bus topology to form a ring is achieved
with two ports (ring ports) of a device in the ring. This device is the redundancy manager. All
other devices in the ring are redundancy clients.

Network structures and network configuration
2.2 Media redundancy
The two ring ports of a device are the ports that establish the connection to the two
neighboring devices in the ring topology. The ring ports are selected and set in the
configuration of the relevant device. In STEP 7 and on the S7 Ethernet CP modules
themselves, the ring ports are indicated by an "R" after the port number.
Note
Before physically closing the ring, download the configuration of your STEP 7 project to the
individual devices.
How media redundancy works in a ring topology
When using media redundancy, the data paths between the individual devices are
reconfigured if the ring is interrupted at one point. Following reconfiguration of the topology,
the devices can once again be reached in the resulting new topology.
In the redundancy manager, the 2 ring ports are disconnected from each other if the network
is uninterrupted. This prevents circulating data frames. In terms of data transmission, the ring
topology is a linear bus topology. The redundancy manager monitors the ring topology. It
does this by sending test frames both from ring port 1 and ring port 2. The test frames run
round the ring in both directions until they arrive at the other ring port of the redundancy
manager.
An interruption of the ring can be caused by loss of the connection between two devices or
by failure of a device in the ring.
If the test frames of the redundancy manager no longer arrive at the other ring port because
of an interruption in the ring, the redundancy manager connects its two ring ports. This
substitute path once again restores a functioning connection between all remaining devices
in the form of a linear bus topology.
As soon as the interruption is eliminated, the original transmission paths are established
again, the two ring ports of the redundancy manager are disconnected and the redundancy
clients informed of the change. The redundancy clients then use the new paths to the other
devices.
The time between the ring interruption and restoration of a functional linear topology is
known as the reconfiguration time.
If the redundancy manager fails, the ring becomes a functional linear bus.
Media redundancy methods
The following media redundancy methods are supported by SIMATIC NET products:
● HRP (High Speed Redundancy Protocol)
Reconfiguration time: 0.3 seconds
● MRP (Media Redundancy Protocol)
Reconfiguration time: 0.2 seconds
The mechanisms of these methods are similar. HRP and MRP cannot be used in the ring at
the same time.

MRP
The "MRP" method conforms to the Media Redundancy Protocol (MRP) specified in the
following standard:
IEC 62439-2 Edition 1.0 (2010-02) Industrial communication networks - High availability
automation networks Part 2: Media Redundancy Protocol (MRP)
The reconfiguration time after an interruption of the ring is a maximum of 0.2 seconds.
Requirements
Requirements for problem-free operation with the MRP media redundancy protocol are as
follows:
● MRP is supported in ring topologies with up to 50 devices.
Except in PROFINET IO systems, topologies with up to 100 SCALANCE X-200 and
SCALANCE X-300 IE switches were tested successfully.
Exceeding this number of devices can lead to a loss of data traffic.
● The ring in which you want to use MRP may only consist of devices that support this
function.
These include, for example, some of the Industrial Ethernet SCALANCE X switches,
some of the communications processors (CPs) for SIMATIC S7 and PG/PC or nonSiemens devices that support this function.
● All devices must be interconnected via their ring ports.
Multimode connections up to 3 km and single mode connections up to 26 km between
two SCALANCE X IE switches are possible. At greater distances, the specified
reconfiguration time may be longer.
● "MRP" must be activated on all devices in the ring (see section "Auto-Hotspot").
● The connection settings (transmission medium / duplex) must be set to full duplex and at
least 100 Mbps for all ring ports. Otherwise there may be a loss of data traffic.
– STEP 7: Set all the ports involved in the ring to "Automatic settings" in the "Options"
tab of the properties dialog.
– WBM: If you configure with Web Based Management, the ring ports are set
automatically to autonegotiation.

The following schematic shows a possible topology for devices in a ring with MRP.
Figure 2-9
Example of a ring topology with the MRP media redundancy protocol
The following rules apply to a ring topology with media redundancy using MRP:
● All the devices connected within the ring topology are members of the same redundancy
domain.
● One device in the ring is acting as redundancy manager.
● All other devices in the ring are redundancy clients.
Non MRP-compliant devices can be connected to the ring via a SCALANCE X switch or via
a PC with a CP 1616.

MRPD
MRPD - Media Redundancy with Planned Duplication
The MRPD procedure is specified in IEC 61158 Parts 5 and 6 type 10 "PROFINET". It allows
bumpless redundant linking of devices.
The cyclic IRT frames are duplicated and the PROFINET devices connected to the ring send
their data in both directions. The devices receive this data at both ring ports and this reduces
the reconfiguration time of the ring. As with MRP, a redundancy manager prevents
circulating data frames.

HRP
HRP - High Speed Redundancy Protocol
HRP is the name of a redundancy method for networks with a ring topology. The switches
are interconnected via ring ports. One of the switches is configured as the redundancy
manager. The other switches are redundancy clients. Using test frames, the redundancy
manager checks the ring to make sure it is not interrupted. The redundancy manager sends
test frames via both ring ports and checks that they are received at the other ring port. The
redundancy clients forward the test frames.
If the test frames of the redundancy manager no longer arrive at the other ring port of the
redundancy manager due to an interruption, the redundancy manager switches through its
two ring ports and informs the redundancy clients of the change immediately.
Standby redundancy
Standby redundancy is a method with which several rings each of which is protected by HRP
can be linked together redundantly. In the ring, a master/slave device pair is configured and
these monitor each other via their ring ports. If a fault occurs, the data traffic is redirected
from one Ethernet connection (standby port of the master or standby server) to another
Ethernet connection (standby port of the slave).
Requirements
● HRP is supported in ring topologies with up to 50 devices. Exceeding this number of
devices can lead to a loss of data traffic.
● The following devices support HRP:
– SCALANCE X500
– SCALANCE X400
– SCALANCE X300
– SCALANCE X200
● All devices must be interconnected via their ring ports.

RNA
Redundant Network Access (RNA)
In Siemens Industry, Redundant Network Access (RNA) stands for devices and software that
support the redundancy protocol "Parallel Redundancy Protocol" (PRP). RNA allows the
connection of devices to redundant Ethernet network structures.
The product names of the RNA devices end with "RNA".
Some devices of the SCALANCE X-200RNA product line also support the redundancy
protocol "High-availability Seamless Redundancy" (HSR).
2.2.7
PRP
Parallel Redundancy Protocol (PRP)
The Parallel Redundancy Protocol (PRP) is a redundancy protocol for Ethernet networks. It
is specified in IEC 62439-3.
The areas of application of PRP are distributed applications with high reliability demands that
depend on the high availability of the network. Compared with classic fault-tolerant networks,
bumpless path redundancy is possible with PRP.
PRP has the advantage that it uses parallel, separate networks made up of standard
network components. End devices that use this method are connected to both networks via
two ports of an interface of the device or via a SCALANCE X-200RNA or a RUGGEDCOM
RS950G. This means that data of the end device can be transferred at the same time via
both networks. If a transmission path is interrupted, the data reaches the communications
partner via the second parallel path.
If a network is interrupted, communication can be maintained with PRP via the second
network without any interruption. Reconfiguration times required with the other redundancy
protocols (e.g. MRP) do not therefore apply.
An end device with PRP capability can be connected to redundant networks by using the
PRP protocol. An end device that does not have PRP capability can be connected to a
redundant network via a SCALANCE X-200RNA or RUGGEDCOM RS950G that does have
PRP capability. This means that PRP can also be used by end devices without PRP
capability.
Devices with PRP capability are located in two independent networks with the same MAC
and IP address.
Communication with PRP
PRP is only possible when two end devices are connected via two independent networks
(LAN A and LAN B).
Each end device is represented in both networks LAN A and LAN B with the same MAC and
IP address.

System Manual, 05/2016, C79000-G8976-C242-08
75
Network structures and network configuration
2.2 Media redundancy
PRP communication is handled using the following mechanisms:
● Send
An end device with PRP capability duplicates each frame to be sent on the PRP
interface. The two duplicates are sent via the 2 ports of the PRP interface via the two
separate networks LAN A and LAN B to the communications partner.
If the end device does not have PRP capability, the frame to be sent is duplicated by an
X-200RNA to which the end device is connected and sent via LAN A and LAN B to the
communications partner.
● Received
The two duplicates are received by an end device with PRP capability via LAN A and
LAN B on the two ports of the PRP interface.
If the end device does not have PRP capability, the receiving end device must be
preceded by an X-200RNA. The X-200RNA forwards the first frame to arrive to the
addressee. The second frame is discarded ((N-1) redundancy).
Connecting up and cabling
Each frame duplicate sent using the PRP mechanisms is given in identifier that specifies
whether it is sent via LAN A or LAN B.
Note
Cabling
Make sure that all the PRP ports of the nodes and the SCALANCE X204RNA /
RUGGEDCOM RS950G on LAN A and LAN B are connected correctly. A frame with the
identifier "LAN A" must be received at the corresponding port.
The PRP ports of SIMATIC NET devices have the following identifiers. The CP ports are the
ports of the interface with PRP capability.
● Ports for connection to LAN A
– CPs: X2/P1
– SCALANCE X204RNA: PRP A
● Ports for connection to LAN B
– CPs: X2/P2
– SCALANCE X204RNA: PRP B

2.2.8
STP / RSTP / MSTP
Spanning Tree Protocol (STP)
STP (IEEE 802.1D standard) is the method with which loops are prevented in redundant
network structures.
With this method, it is not end devices that know the path from the sender or recipient, but
rather the switches. The switches continuously exchange configuration frames with each
other known as BPDUs (Bridge Protocol Data Unit). Due to the MAC addresses of the
packets passing through, the switches get to know the topology of the network
independently. The network is considered to be a tree.
Sequence
After initialization of the switches, a root bridge is selected. Each switch has an ID that it
passes on to the group. The switch with the lowest bridge ID becomes the root bridge.
All other paths are decided by this root bridge. The other switches select one of their ports as
a root port in the direction of the root bridge. This selection is also made using BPDUs that
the root bridge sends to the switches. The port of switch that receives the BPDU of the root
bridge first adopts the status of root port.
The designated ports are selected from the remaining ports connected to another switch.
This is also done by sending BPDUs. This time the switches send frames to the connected
partners. The port via which the frame reaches the recipient quickest becomes the
designated port.
The other port is deactivated. If there is a disruption or device failure, the network needs to
be reconfigured. The devices start to negotiate new paths only when the interruption occurs.
This can take up to 30 seconds.
Rapid Spanning Tree Protocol (RSTP)
RSTP (IEEE 802.1D-2004 standard) is a further development of STP. RSTP differs from
STP essentially in that the devices are already collecting information about alternative routes
during normal operation and do not need to gather this information after a disruption has
occurred. This allows the reconfiguration time for an RSTP-controlled network to be reduced
to less than 1 second.
This was achieved by the following functions:
● Edge ports
A port that is defined as an edge port is activated immediately after connection
establishment. If a BPDU is received at an edge port, the port loses its role as edge port
and takes part in RSTP again. If no further BPDU is received after a certain time has
elapsed (3 x hello time), the port returns to the edge port status.
● Point-to-point (direct communication between two neighboring devices)
By directly linking the devices, a status change (reconfiguration of the ports) can be made
without any delays.

77
Network structures and network configuration
2.2 Media redundancy
● Alternative port (substitute for the root port)
A substitute for the root port is configured. If the connection to the root bridge is lost, the
device can establish a connection over the alternate port without any delay due to
reconfiguration.
● Reaction to events
A Rapid Spanning Tree reacts to events, such as a connection abort, without delay.
There is no waiting for timers as in spanning tree.
● Counter for maximum number of bridge hops
The number of bridge hops a package is allowed to make before it automatically
becomes invalid.
In principle, therefore with rapid spanning tree, alternatives for many parameters are
preconfigured and certain properties of the network structure taken into account to reduce
the reconfiguration time.
Multiple Spanning Tree Protocol (MSTP)
MSTP is a further development of RSTP. MSTP is defined in the IEEE 802.1s standard,
subsequently IEEE 802.1Q.
Among other things, it provides the option of operating several RSTP instances or VLAN
groups within different virtual networks (VLAN - Virtual Local Area Network) so that; for
example; paths that would block the simple Rapid Spanning Tree Protocol for data traffic
globally can be available within individual VLANs.
2.2.9
Link aggregation
Link aggregation
With link aggregation, several parallel physical connections with the same transmission
speed are grouped together to form a logical connection with a higher transmission speed.
This method based on IEEE 802.3ad is also known as port trunking or channel bundling.
Link aggregation works only with full duplex connections with the same transmission speed
in point-to-point mode. This achieves multiplication of the bandwidth or transmission speed.
If part of the connection fails, the data traffic is handled via the remaining parts of the
connection.
To control and monitor, the Link Aggregation Control Layer (LACL) and the Link Aggregation
Control Protocol (LACP) are used.

Security Configuration Tool
This program is integrated in STEP 7 but can be called up independent of STEP 7. It allows
the configuration of the security mechanisms for a device. In standard mode there are many
parameter defaults which simplifies the fast creation of a project. In advanced mode
individual settings are possible for many parameters so that complex use scenarios can also
be created.
Among other things, with the Security Configuration Tool the firewall of the device is
configured that restricts the data traffic according to the specified rules to prevent
unauthorized access The data of the security configuration is stored in an SCT project that
can also be used by the Softnet security client.
Softnet security client
The Softnet security client allows secure remote access to security modules and the
programmable controllers behind via a public network. The function of the program is based
on an IPsec tunnel connection in the VPN (Virtual Private Network). It uses the configuration
created by the Security Configuration Tool.
2.3.2
Firewalls
"Gatekeeper" function
Put simply, a firewall is a device or a software application inserted between the network and
the outside world as a "gatekeeper" to protect the network. The firewall represents the only
access to the local area network from outside and the entire data traffic crossing the
boundaries of the network is directed via the firewall. This means that the firewall can block
unwanted and potentially dangerous access from the outside. Various techniques are
available.
Packet filter
A packet filter inspects data packets entering or leaving the network, their sender and
receiver addresses and the "port", or service, to which the data packet will be transferred.
Such services might be E-mail, file transfer with FTP, database access, SSH for encrypted
transfer etc.
Filter rules stored in the firewall now block the access to certain addresses or certain
services. Firewalls can implement complex filter rules in which, for example, service "A" is
available only for IP addresses "B" and "C" but is not allowed for other communications
partners.
"Stateful Inspection"
"Stateful Inspection" goes a step further than the packet filter and takes into consideration
the "context" within the communication in addition to the addresses and ports.
Industrial Ethernet
82
System Manual, 05/2016, C79000-G8976-C242-08
Network structures and network configuration
2.3 Network security
In concrete terms, this means, for example, that Web pages sent be an external server to an
internal computer can only pass through the firewall if the internal computer has actually
requested this page.
Such techniques are, for example, relevant for preventing "Denial of Service" attacks (DoS)
in which an external intruder sends queries to the computer under attack from numerous
computers at the same time in the hope of overloading and paralyzing the network. Since,
however, the stateful inspection detects these illegitimate queries at the boundary of the
local area network, local traffic continues unaffected by the DoS attacks.
"Network Address Translation" (NAT)
"Network Address Translation" ("NAT") is a function with which a router replaces the
addresses of the local nodes involved in data traffic with its own IP address whenever the
traffic goes beyond the network boundaries. Incoming replies are only assigned to the actual
addressees with their IP addresses after passing the firewall.
This mechanism can be used for ergonomic reasons since to the outside only one single IP
address is required for any number of local nodes.
It does, however, also provide a certain protection from attacks since only one single
address is visible to the outside namely that of the firewall. A "naive" attack would always be
aimed at the firewall directly and not at the local computers being protected behind it.
"Network Address Port Translation" (NAPT)
Compared with NAT, NAPT goes one step further. With NAPT, in addition to the IP
addresses, the ports of the local nodes are also replaced. Incoming replies are then
assigned back to the corresponding IP addresses and ports of the local nodes.
"Personal firewalls"
For professional applications, the firewalls normally used are separate devices. The
alternative to these devices are "personal firewalls" in the form of software running on the
target computers themselves.
Personal firewalls cannot, however, provide the same security as dedicated devices. Errors
in the operating system or badly programmed or configured personal firewalls allow an
attacker to avoid the "gatekeeper" filter function and to attack the target computer or target
network despite the firewall.
2.3.3
"Virtual Private Networks" (VPNs)
The function of Virtual Private Networks
A VPN means that a public network is used to transfer private data by "embedding" the
private communication in the traffic of the public network.
The nodes of the VPN have the impression that they are connected directly to each other.

network. For this reason, the mechanisms are known as "tunneling" through the public
network. Using VPNs, for example, two subnets at a considerable physical distance from
each other can be connected so that the users can address them as one unit.
Security of VPNs
The term "private" relates primarily to the use of VPNs and not to the confidentiality of the
data: VPNs are not automatically secure since the data traffic is not encrypted from the very
beginning. If, however, suitable encryption techniques are used, communication via the VPN
is practically safe from eavesdropping.

Cell protection concept
Basics
With the cell protection concept, a plant network is divided into individual protected
automation cells to ensure security for the automation systems; within these cells, all the
devices can communicate securely with each other. In the sense of the cell protection
concept, production units, for example, are worthy of protecting.
The following graphic illustrates this. A production cell is protected from unauthorized access
from the remaining enterprise network by a SCALANCE S firewall.

Optimization of a power screwdriver control
Task
Handheld compressed air screwdrivers are used in the final assembly of motor vehicles and
they can be supplied via mobile stations on overhead monorails. These units need to be
replaced by new, motor-driven screwdriver stations and the customer would like to do away
with the previously necessary sliding contacts that were always subject to wear and tear.
Solution
The new solution is based on Industrial Wireless LAN. To allow wireless data
communication, an RCoax cable ① is laid along the path of the screwdriver stations. The
RCoax cable is connected to the antenna output of a SCALANCE W788-1 M12 ② access
point. This means that there is a defined RF field available around the RCoax cable. Via the
Ethernet interface of the access point, there is a connection to the plant controller ③ and the
server of the assembly line ④.
⑤ The communications partner on the screwdriver stations is a SCALANCE W748-1 M12
⑥ client module.

⑦ The data exchange with all components of the mobile station is handled by a SCALANCE
X208PRO switch. The station is controlled via a panel PC ⑧ and the screwdriver controller

⑩ The new screwdriver stations are moved by a geared motor connected via the distributed
I/O.
Benefits
● Low investment costs thanks to fewer screwdriver stations.
● Reduction of maintenance costs and downtimes with reliable wireless and therefore data
transmission to mobile communications partners free from wear.
● Shorter downtimes if a fault occurs thanks to the C-PLUG (configuration plug) in the
SCALANCE devices. Devices can be replaced without a programming device and without
specialist personnel.
● Higher productivity and process reliability because all data of the plant controller (for
example workpiece IDs, screwdriver data and assembly information) is also available
directly on the screwdriver stations. Other applications for quality assurance are also
easy to integrate.
● The SCALANCE wireless devices used W788-1 M12 or W748-1 M12 has a robust metal
housing with degree of protection IP65 and are designed specially for industrial use.

Process automation in hazardous areas
Task
The aim was to allow mobile access to the process data of the entire plant in a hazardous
area (production of polyoxymethylene thermoplastic). Extremely complicated constraints had
to be taken into account when interfacing to the existing PCS 7 plant. The wireless network
had to work in an industrial building made of reinforced concrete with unspecified fittings
over seven floors. Added to this, were the chemical load and the high temperature
differences resulting from the production process.
Solution
① All the SIMATIC S7-400 and SIMATIC S7-300 controllers ② involved in the production
process are connected to the SIMATIC PCS 7 server via Industrial Ethernet.
③ A SCALANCE X208PRO controls data exchange with the access points.
④ In the hazardous area, several SCALANCE W786 access points with integrated antennas
ensure stable illumination of the RF field. This device type was selected because it meets all
the requirements reliably: The degree of protection IP65 in conjunction with an extended
temperature range of -40 to +60 °C and the high mechanical stability providing resistance to
vibration and shock ensure high availability of the entire system.

Automation of gantry cranes
Task
Two gantry cranes are used in a cold rolling mill to handle the steel coils. Fully automated
and fail-safe control of these cranes is required because damage to the steel coils puts up
costs considerably. The intention was to minimize maintenance effort and to reduce
operating costs. The fail-safe monitoring of the 14 entrances and exits of the 16,000 m2

is exchanged via PROFIsafe.
⑧ All access is monitored by an ET 200S PN IO.
⑨ A SIMATIC S7-300F processes all the data of the access monitoring and can, when
necessary, stop the movement of the crane via the connected access point ⑩.
Benefits
● By using Industrial Wireless LAN, no cables need to be laid for communication.
● SCALANCE W788-1 access points are designed to be suitable for industry and are
therefore capable of withstanding the mechanical load caused by shock and vibration
when used on the crane bridges. These devices are also available in degree of protection
IP65 and can be used without problems in areas subject to dampness and spray water.
● Lower operating costs thanks to maintenance-free components.
● With PROFINET and the PROFIsafe profile, safety-oriented data can also be transferred

Transportation vehicles in a building need to be controlled using wireless. These vehicles
move steel pipes with a weight of several tons. One important aspect was easy scalability if
additional vehicles are used. Another requirement was the reliable accessibility of the
vehicles in all areas of the building and high mechanical stability of the devices used on the
vehicles in particular with regard to vibration.
Solution
The following graphic shows the topology of the implemented solution and the interfacing to
the existing IT structure:
① The plant is controlled via a WinCC system that accepts user input and displays feedback
from the individual system components.
② Here, controllers from other operational areas are also connected to allow

④ Industrial Wireless LAN is used for the wireless communication with the vehicles. In the
production plant, several SCALANCE W774-1 access points ⑤ ensure a full-coverage
IWLAN RF field. iPCF can be used with these devices. This minimizes the handover times
when the vehicle moves from one wireless cell to another.
⑥ To allow this, each vehicle is equipped with a SCALANCE W734-1 client module. The
control information received via wireless is forwarded via the Ethernet interface of the W7341 client to a SIMATIC S7-300 controller. There, data traffic is handled by a CP 343-1 Lean

⑥ IWLAN was selected for the communication between the stationary parts of the system
and the mobile crane carriage. This meant that the previously required cable festoons were
no longer necessary. Broken cables and the associated maintenance effort would therefore
no longer be a problem. Two SCALANCE W774-1 access points ensure reliable wireless
coverage in the area in which the crane carriage moves.
⑦ Each crane carriage is equipped with a SCALANCE W722-1 and an IE/PB Link PN IO ⑧
that converts the received wireless control signals for PROFIBUS and forwards them to the
ET 200S ⑨ on each crane carriage. In conjunction with absolute value encoders, this
achieves precise movement and positioning of the crane carriage.
Benefits
● Reliable and high-speed communication with PROFINET IO and Industrial Wireless LAN
with iPCF.
● Protection of investment by using IE/PB Links. The existing PROFIBUS I/O can continue
to be used unchanged.
● By integrating the absolute value encoders in the distributed ET 200S, additional cabling
is unnecessary.
● Absence of maintenance and operational safety thanks to wireless transmission between
the stationary part of the system and the crane carriage.
● Although remote access to the system via the factory network is possible, a SCALANCE
S612 protects against unauthorized access.
● If requirements change, the system can be easily expanded or adapted.

Using Power over Ethernet
Task
In a plant in the food and beverages industry, two new production areas and an additional
outside storage area need to be integrated in an existing IT infrastructure. Due to the large
distances between the new parts of the company minimization of the cabling effort was
sought.
Solution
This aim is to be met by the practically end-to-end use of components capable of PoE. In
addition to this, access points allow access to the company network from any location. The
starting point for connecting the new production areas and the storage area to the company
network are two devices of the SCALANCE X series that provide an adequate number of
Ethernet ports with PoE capability. The SIMATIC M440 readers ① of the first production
area are connected to the company network via a SCALANCE XM408-8C ②. The basic
device XM408-8C can be expanded by port extenders. When necessary, 24 ports are
available if additional readers become necessary. With a suitable port module, connection to
the existing fiber-optic cables can be achieved without problems.
The second production area with office and the outside storage area are supplied by a
SCALANCE XR324-4M PoE ③. Both in production and in the storage area the requirements
are the same: An access point will make access to the company network possible, for
example to query logistics and job data. In addition to this and IP camera will monitor the
entire area. In production, a SCALANCE W788 ④ will be used that is ideal for this use case

measures. Only an Ethernet cable needs to be laid in the outside storage area, the access
point and the camera are connected to the network via a SCALANCE X108PoE ⑥.
Benefits
● Problem-free integration of the SCALANCE X devices due to the availability of port
modules for all common transmission media.

In a brickworks, raw bricks are transported to the drying kiln by a shuttle conveyor ①. The
functions of the shuttle conveyor are controlled by an S7-300. The movements of the shuttle
conveyor are synchronized with the production process in the stationary parts of the works
with which the conveyor communicates via a wireless PROFIBUS modem ②. The doors of
the drying kiln open automatically when the conveyor arrives and close again automatically.
The original solution had a wireless PROFIBUS modem ③ and the ET 200 I/O ④ and
operator control stations ⑤ required for production.
This solution alone eliminates numerous problems that occurred previously with the trailing
cables but nevertheless there were occasional short interruptions in communication. The
reason was that the transmission speed of the wireless PROFIBUS communication was not
fast enough for this situation.
Solution
The new solution consists of Industrial Wireless LAN and PROFINET IO. This combines a
high data rate in the wireless communication with a communications concept for modular
distributed applications based on Ethernet.
⑥ The CPU 315-2 PN/DP used on the conveyor has a PROFINET interface to connect
distributed field devices. For the wireless communication, a SCALANCE W748-1 ⑦ is
connected as a client module.

Redundant coupled rings with a connection to an office network
Task
In a production plant, two ring topologies need to be interconnected reliably. Faults or the
failure of a connecting cable should not have any influence on the data traffic. Data must
also be exchanged with the office network of the plant.
Solution
The production network consists of two redundant rings. One switch ① in each of the ring
topologies is configured as the redundancy manager (RM) but this does not forward any
frames if the transmission path is intact. This means that the ring is interrupted for data traffic
at the redundancy manager. If a section of the ring fails, the redundancy manager closes the
connection between its ring ports. As a result, all the devices in the ring remain accessible
for data traffic.
Due to the high requirements for reliability, the coupling of the two rings is also redundant. In
regular operation, the data traffic between the two rings is via cable ②, the device ③ adopts
the function of standby master. In this situation, the cable ④ does not transfer any data
because the standby slave ⑤ is controlled accordingly by the standby master ③.
If the standby master ③ recognizes that the connection via the cable ② is faulty or
interrupted, it activates the cable ④ for data exchange via the standby slave ⑤. Cable ⑥

3.8 Redundant coupled rings with a connection to an office network
serves as the connection between the standby master ③ and the standby slave ⑤. This is a
normal network segment that is simply used for the additional function of the standby
coupling.
All cables are designed for Gigabit Ethernet because there is an extremely high volume of
data to be transferred. Either copper cable or fiber-optic cable can be used without problems
because there are SCALANCE X-300 components with gigabit ports for all possible media.
Due to the redundant operation in the two rings of the plant network, Spanning Tree/RSTP
cannot be used because an IE switch cannot use both mechanisms at the same time. If
Spanning Tree/RSTP is necessary in the office network ⑦, passive listening must be
activated for devices ⑧ and ⑨. They then forward (R)STP configuration frames
transparently even when (R)STP is disabled for them. This behavior does not conform with
the IEEE 802.1d standard but allows the connection of network segments with media
redundancy and those that use Spanning Tree/RSTP.
Benefits
● Extremely high reliability thanks to media redundancy and the redundant coupling of ring
topologies.
● High data throughput thanks to gigabit technology.
● Freedom of choice in terms of the transmission medium; depending on specific
requirements either twisted-pair cables or fiber-optic cables can be used.
● Connection to networks with activated Spanning Tree/RSTP by using passive listening.

Task
In an assembly plant, access to field devices and the control technology should only be
possible for authorized personnel for commissioning, maintenance and service. Due to the
size of the plant, network access should also be possible for mobile nodes. In particular, in
this case, reliable protection of the automation cells against unauthorized access,
manipulation and espionage is necessary.
Solution
Within the automation cells ① and ②, devices can be used without their own security
functionality. The entire data exchange with these devices is via a SCALANCE S612 ③ that,
among other things, provides the function of a firewall. The protection also extends to layer 2
frames if the SCALANCE S612 is not operating as a router.
④ Devices in public networks can also communicate with the automation cells if they use
the SOFTNET Security Client software. This means that the PC/PG is automatically
configured so that it can establish a secure IPsec tunnel in the VPN (Virtual Private Network)
to one or more SCALANCE S612 modules. As a result, STEP 7 for example can be used to
access devices in an automation cell protected by a SCALANCE S612 via a secure tunnel.
This cell protection concept allows the use of effective security structures even for access by
external devices.

● Mobile devices can access the automation cells from any location in the plant which
means that the number of stationary nodes for diagnostics and service can be greatly
reduced.
● The security mechanisms of the SCALANCE S612 and the SOFTNET Security Client are

Task
In a car bodywork plant, the company network includes both the office network, the data
processing center and the automation cells in production. The integration of all company
areas allows continuity from the enterprise to the field level. This means that process data
such as numbers produced, manufacturing number and type names are available throughout
the company. Apart from this, fully integrated diagnostics can be created for field devices
and network components. This continuity does, however, involve certain risks. There is a
danger of unauthorized access from the office network to the automation cells and the
influence of one automation cell on another. The network needs to be structured so that
these weak points are eliminated. The configuration should also be simple to create since
personnel without special training in security will be involved in commissioning and service.
Solution
① The office network includes a Syslog server ② that also logs unauthorized access
attempts and overload situations.
③ Switches of the type SCALANCE X324-12M are responsible for handling the data traffic.
With their gigabit ports, these devices are not only suitable for a high data throughput, they
also provide wide-ranging configuration options for parameters relevant to security. Using
the access control function, for example, individual ports can be blocked for unknown nodes.

④ Each automation cell includes several components that are connected to the network
(controllers, robots, field devices). A SCALANCE S602 ⑤ acting as a firewall filters the data
packets and allows communications connections according to the firewall rules. Criteria for
the filtering might be the IP address, the MAC address or the communications protocol.
There is also an option for limiting overload. The logging functionality allows access
monitoring and logs attacks and attempted access to allow preventive measures to be taken.
Syslog information such as process data is automatically sent to the Syslog server. To allow
effective protection of the automation cells, an IP address conversion is necessary and for
this the SCALANCE S602 uses the NAT and NAPT methods.
These measures implement a comprehensive cell protection concept for the individual
production areas. The production network is protected effectively and reliably from
unauthorized access from the office network and the office network is also protected from
any influence from the production network.
Benefits
● Effective protection from mutual influence between production and office network.
● Protecting the plant from unauthorized attacks and communication overload by using

An existing network needs to be replaced by a new future-proof network. The aim was not
only to increase the bandwidth (gigabit), but to provide ideal conditions for PROFINET. The
intention was to use only open communications standards and there was very little time for
the implementation.
Solution
① A redundant glass fiber-optic ring was selected as the backbone. The total length of this
cable is approximately 2 km.
② The ring topology was set up with SCALANCE X308-2 devices. This device has three
gigabit ports (2 x fiber-optic, 1 x RJ-45) as well as comprehensive management functions.
The gigabit ports are used for a high-speed connection between the switches. One
SCALANCE X308-2 is configured as the redundancy manager and this prevents frames from
circulating if the transmission path is intact. If the transmission path is interrupted, this closes
the connection between its ring ports and restores a connection between all the components.
③ The second level linear bus structures are made up of SCALANCE X208 devices. These
devices also have a compact housing suitable for industry that is, for example, equipped with
securing collars for the RJ-45 jacks. In conjunction with the FastConnect connectors used,
this achieves a high degree of mechanical stability within the network.

Task
A mobile loading crane in a harbor needs to be supplied with data from a logistics center.
The devices used must be able to stand up to extreme environmental conditions (salt water
spray, strong vibration caused by the movement of the crane).
Solution
The communication between the crane and the logistics center is handled via Industrial
Wireless LAN. The advantage of wireless data transmission is that neither sliding contacts
nor trailing cables are necessary. Taking into account the environmental conditions, this
represents a considerable saving in costs.
① The loading crane is equipped with a SCALANCE W786 and a PC for displaying and

for this application due to its resistance to ultraviolet light and salt water. The device is
configured as a client. Thanks to the antennas integrated in the housing, external antennas
and the associated cabling are unnecessary.
② A SCALANCE W786 is also mounted on a building of the logistics center and acts as the
access point.
③ The integration of the access point in the company network is achieved with a
SCALANCE X104-2. Among other things, this switch provides two interfaces for fiber-optic

Product families
The name SCALANCE stands for SIMATIC NET network components for simple setup,
management and operation of Industrial Ethernet LANs. The product families are as follows:
● SCALANCE X is the product family of Industrial Ethernet switches. Switches are active
network components that distribute data to specific addressees, control network traffic
and ensure that the load on network connections is optimally distributed.
SCALANCE X switches are available in a wide range of variants with electrical and/or
optical ports, and in some cases with special functionalities to meet strict real-time
requirements.
● SCALANCE W is the family of components and accessories for wireless local area
networks ("WLANs"). The use of access points, clients and accessories allows the
connection of mobile nodes and the establishment of networks in exacting environments.
SCALANCE W components are distinguished by their robustness, security and reliability.
Wireless transmission can be implemented using omnidirectional antennas, directional
antennas or over short distances with leaky feeder cables (RCoax cable).
● SCALANCE S security modules protect automation networks from unauthorized access
and unnecessary communication load. Both eavesdropping and attacks by outsiders are
prevented reliably. Even if there are disturbances in the external network, data traffic in
the automation cell remains unaffected. Communication is protected regardless of the
application protocol used.
● SCALANCE M devices are used as LTE, UMTS, EGPRS (GPRS with Edge) and GPRS
routers for wireless IP communication of Industrial Ethernet-based programmable
controllers via LTE, UMTS / GSM mobile wireless networks. With LTE and UMTS high
transmission speeds are achieved. An integrated firewall provides extensive security
functions. Some models can be used both as VPN servers and VPN clients (IPsec).

4.2
Common properties of all SCALANCE devices
Properties shared by all SCALANCE devices
All SCALANCE devices have the following properties. If there are exceptions, this will be
pointed out in the description of the relevant device.
Autocrossover function
All SCALANCE devices have an integrated MDI/MDIX autocrossover function on their
electrical ports making it possible to use straight-through cables. This prevents malfunctions
resulting from mismatching send and receive lines. This makes installation much easier for
the user.
Autonegotiation
All SCALANCE devices also have the autonegotiation function. Autonegotiation means the
automatic detection of the functionality of the interface at the opposite end. Using
autonegotiation, repeaters or end devices can detect the functionality available at the
interface of a partner device allowing automatic configuration of different types of device.
With autonegotiation, two components connected to a link segment can exchange
parameters and with these parameters set themselves to the supported communication
functionality.
The SCALANCE devices are therefore plug-and-play devices that require no settings when
they are put into operation.
Please note the following:
● Devices not supporting autonegotiation must be set to half duplex.
● The port speed and duplex mode must be set identically on the connection partners
otherwise frames may be lost.
Fault mask
On all SCALANCE devices with a button on the front panel, it is possible to set a specific
configuration as the desired status (good status). Deviations from this setting occurring
during operation are treated as errors.
Monitored error statuses include, for example, the status of the power supply or link down to
a communications partner, to which the SCALANCE device reacts with a fault LED and by
opening the signaling contact.
Avoiding loops
The typical configuration of a network with the SCALANCE products is a tree structure. The
direct connection of two ports on the switch or accidental connection over several switches
causes an illegal loop. Such a loop can lead to network overload and network failures.
When configuring the network with SCALANCE XB200, X300, X400 and X500, meshing is
possible since, in this case, the Rapid Spanning Tree algorithm can eliminate loops. At the
same time, RSTP increases the availability of the network. If one connection fails, the
redundant connection is activated.

Web Based Management for configuring networks
Configuration over a Web interface
All SCALANCE devices that have management functions can be configured using "Web
Based Management" (WBM).
The devices have an integrated Web server that can be accessed by the configuration
engineer with a browser via every Ethernet connection. The server then provides a series of
Web pages. On these Web pages, the configuration engineer can make all important
settings and can also run diagnostics and report functions.

Management functions
The SCALANCE X200-, SCALANCE X300-, SCALANCE X400- and SCALANCE X500
devices are equipped with management functions. These devices are also known as
"managed switches". The managed devices provide numerous configuration and diagnostics
functions that make the operation of an Industrial Ethernet network much more convenient.
The SCALANCE X100, SCALANCE XB000 and SCALANCE X005 devices do not have
management functions. These "unmanaged switches" are therefore cheaper.
This SCALANCE X modular switches
To achieve the greatest possible flexibility in terms of interfaces, the use of the modular
devices such as SCALANCE XR324-12M, SCALANCE X308-2M, and SCALANCE XR-55212M is recommended. By making use of media modules, these provide the maximum
possible variability.
Electrical and optical interfaces
The SCALANCE X devices can be used as switches in both optical and electrical Industrial
Ethernet networks. Each performance class therefore includes devices with varying numbers
of electrical and optical interfaces. The optical interfaces also include versions specially
designed to cover long distances. These are available in devices that have LD, LH, LH+ or
ELH in the device designation.
Combo ports
Combo port is the name for two communication ports. A combo port has the two following
jacks:
● a fixed RJ-45 port
● an pluggable transceiver slot that can be equipped individually
Of these two ports, only one can ever be active. Using the mode, you can decide how the
ports are prioritized. The port name is the same on both jacks of the combo port, for example

"P3C". There is an LED for each combo port. The LEDs for the combo ports can be identified
by a vertical line and the word "COMBO". The labeling of the combo port LEDs does not
differ from that of the other LEDs, e.g. "P3".
Fault-tolerance due to redundancy
The SCALANCE X200, X300, X400- and X500 switches have functions that allow the setup
and management of redundant networks in a ring topology. These networks can handle the
failure of individual nodes or cable sections and "divert" the data traffic so that the network
remains available.
IRT for strict real-time requirements
Devices with the IRT suffix (Isochronous Real Time) are particularly suitable for applications
in which a data transmission must be guaranteed at fixed intervals. To allow this, all devices
in an Industrial Ethernet have the same timebase. The messages of the preferred nodes are
transmitted together at previously configured times. Frames of other nodes are held back by
the IRT switches and sent later.
Media converter SCALANCE X100
The media converters of the SCALANCE X-100 line are particularly suitable for applications
in which two Industrial Ethernet networks implemented with different media need to be
linked. These have only two interfaces and therefore fit into an extremely narrow casing.
They can also be used in a redundant ring.
The media converters have electrical and optical interfaces to link optical networks with
electrical networks and to link existing network segments or individual end devices.
Devices for special environmental conditions
Some switches are available in special designs so that they can be used in special
environments. This includes the design of the housing in IP65 with M12 plug-in connectors.
This version has the supplement PRO in the type designation. Switches with the supplement
EEC are approved for expanded environmental conditions.
Notes on installation
When installing the devices note the information in the compact operating instructions of the
individual device. Apart from a few exceptions, the devices are suitable for wall mounting,
DIN rail mounting and S7 standard rail mounting. In individual cases the required type of
mounting can be made possible by using a mounted adapter.
Devices with the supplement R are either suitable as a desktop device or for installation in a
19" rack. To do this, install the mounting aids as described in the compact operating
instructions.

4.4.2
Functions of SCALANCE X devices
Introduction
This section describes certain functions of SCALANCE X devices. For further information on
all the functions, refer to the compact operating instructions of the devices or the
configuration manual.
Signaling contact
The signaling contact is connected to a 2-pin plug-in terminal block. The signaling contact
(optical relay contact) is a floating switch with which error/fault states can be signaled by
breaking the contact.
The following errors/faults are signaled by the signaling contact:
● The failure of a link on one of the two monitored ports.
● The failure of one of the two redundant power supplies.
The connection or disconnection of a communication node on an unmonitored port does not
lead to an error message.
The signaling contact remains activated until the error/fault is eliminated or until the current
status is applied as the new desired status using the button or by Web Based Management.
When the device is turned off, the signaling contact is always activated (open).
Support of virtual networks (VLAN)
There is no physical difference between a virtual network (VLAN) and a normal LAN. The
particular feature of a VLAN is that devices can be assigned to a device group during
configuration. Several of these device groups use a network infrastructure that exists only
once physically. Several "virtual networks" result on the one physical network. Data
exchange and even the transmission of broadcasts takes place only within a VLAN.
You can configure VLANs on the device or using GVRP frames.
MAC address list
If this function is activated for a port, the device only forwards frames received at this port if
their source address exists in the address table.
SCALANCE devices log the information about which MAC address can be reached over
which port in a learning table. Entries in this list are deleted automatically when there is no
further data transfer for the corresponding MAC addresses. The time after which addresses
are deleted if there is no data traffic is set in the 'Aging Time' parameter.
The learning table indicates the Ethernet interface on which a MAC address can be reached.
The MAC address list can be based on the port or MAC addresses.

Network access protection complying with the standard IEEE 802.1X
Ports can be configured for end devices that support authentication according to IEEE
802.1X. The authentication is via a RADIUS server.
IGMP snooping and IGMP querier
IGMP (Internet Group Message Protocol, RFC 2236) is a protocol used for the group
management of IP multicasts.
The group management is on a central device, for example a switch. With IGM snooping, the
switch (IGM querier) queries the multicast group membership of its connected devices. The
switch notes the outgoing interfaces on which devices are located that want to receive
certain multicast IP packets. The switch enters the devices in a list (MAC filter table). When a
switch receives a multicast, the message is forwarded only to the members of the multicast
group. The multicast data traffic is therefore filtered and the load on the network limited.
Bundling network links for redundancy and higher bandwidth
Link aggregation according to IEEE 802.3ad allows several links between neighboring
devices to be bundled to achieve higher bandwidths, see section Link aggregation
(Page 78).
Topology support (LLDP)
The topology is identified using LLDP (Link Layer Discovery Protocol). The devices
exchange LLDP frames with each other. The information is stored and can be represented
graphically by network management software. In the default setting, LLDP is enabled for all
ports; in other words, LLDP frames are sent and received on all ports.
Using the GARP VLAN Registration Protocol (GVRP)
Whether or not a port belongs to a VLAN is set dynamically using GVRP frames.
Forwarding of multicast frames with GMRP (Generic Multicast Protocol)
GMRP is a mechanism for efficient forwarding of multicast frames. With a GARP Information
Declaration (GID), a node registers with the IE switch as recipient for a multicast address.
The IE switch sends this registration to its ports. As a result, this address is also known to
other IE switches and they send multicast frames for this address only to ports that have
received a registration for this address.
Fast redundancy in the ring
The following redundancy methods are possible:
● MRP in the ring with a maximum reconfiguration time of 200 ms, see section MRP
(Page 72)
● HSR with a maximum reconfiguration time of 300 ms, see section HRP (Page 74)

● MRPD (IE switches with IRT) with 250 µs reconfiguration time, see section MRPD
(Page 73)
● Standby redundancy, see section HRP (Page 74)
Limiting the transfer rate of incoming and outgoing data
To limit the transfer load, the maximum number of data packets per second can be specified
for the individual ports.
The limit values can apply to the following category of frames:
● Broadcast: Special form of multicast.
● Multicast: A device sends a single data packet to several recipients
● Unicast: A device sends the data packets to one recipient

PROFINET variant). This minimizes configuration effort and the devices are quickly ready for
use.

SCALANCE X200 Industrial Ethernet switches allow the cost-effective installation of 10/100
Mbps Industrial Ethernet linear (bus), star and ring structures with switching functionality,
where availability of the network or remote diagnostics options are required. The devices
have IP30 protection and are designed for installation in a cabinet. With IP65, the
SCALANCE X208PRO is intended for installation outside a cabinet. The SCALANCE X2022P IRT PRO and SCALANCE X204 IRT PRO devices have IP67 protection.
SCALANCE X200 switches vary in terms of the functions they provide and the number and
type of electrical and optical IE interfaces.
The SCALANCE X200IRT switches form a special class by using the "cut through" switching
mechanism, the optimum solution to meet the real-time requirements of PROFINET.
SCALANCE X200IRT switches allow the installation of isochronous mode real-time Industrial
Ethernet linear bus and star structures with switching functionality. The special requirements
for automation solutions in terms of linear topology, hard real time and unrestricted IT
openness are incorporated in one technology.
The only difference between the devices of the SCALANCE XF200 product line and the
SCALANCE X200 product is the flatter construction.

The managed switches SCALANCE X300 from SIMATIC NET are for use in highperformance plant networks.
With the HSR redundancy function and standby coupling of rings, high network availability
can be achieved. If the connection between these switches is interrupted, the IE switch
SCALANCE X-300 used as the redundancy manager acts like a switch and in a very short
time forms a linear bus from the ring with redundancy manager. As a result, a functional,
end-to-end structure is restored.
Support of IT standards such as VLAN, RSTP, IGMP, and GARP makes seamless
integration of automation networks in existing office networks possible.
The IE Ssitches SCALANCE X-300 and XR300 are designed for use in switching cubicles
and cabinets. The X300 models have a robust metal housing with IP30 protection for
installation on a DIN rail, an S7-300 standard rail or for wall mounting. The XR300 models
are intended for installation in the 19" rack.
All devices have C-PLUG to back up the configuration data and a signaling contact. They are
suitable for the use of a redundant power supply.

Media modules
The use of media modules in partially and fully modular variants of the SCALANCE X-300
switches allows the expansion of networks by subsequently plugging in additional media
modules in unused media module slots and allows a changeover of the cabling technology
(the example change from copper to fiber-optic or from multimode to single mode fiber-optic
cable).

The power supply units of the SCALANCE PS-900 PoE series, were specially developed to
supply the extender module PE408PoE with power. There are two product variants
avaliable:
● SCALANCE PS9230 PoE for 120/230 VAC input voltage
● SCALANCE PS924 PoE for 24 VDC input voltage
The devices with degree of protection IP20 can be used in ambient temperatures between 40 °C und +70 °C. A SCALANCE PS-900 PoE supplies a maximum power of 86 W. To
supply all eight ports of a PE408PoE with power two SCALANCE PS-900 PoE must
therefore be connected.

field devices and ensures high plant availability with wide-ranging diagnostics options and
high transmission speeds. Due to the scalability of the basic device and optionally available
layer 3 functions, the network can be set up specially for relevant application or adapted and
expanded at any time. SCALANCE XR500 switches are suitable for setting up electrical and
optical Industrial Ethernet linear bus, star or ring structures. With transmission rates up to 10
Gbps, the switches can be used as Industrial Ethernet backbone switches and as hubs in the
plant bus (redundant connection possible).
Apart from four integrated SFP+ slots (for SFP+ transceivers) (10 Gbps) or SFP transceivers
(1000 Mbps) the device variants XR528-6M and XR552-12M provide six or 12 media module
slots. These can be fitted with electrical and/or optical 4-port media modules. Using media
modules or SFP+/SFP allows:
● • Expansion of networks by adding additional media modules in unused media module
slots
● Replacement of the cabling technology, for example converting from copper to FO cable
or from multimode to single mode FO cable
● The transmission rate to be changed, e.g. from 1000 Mbps to 10 Gbps
With their low height of one height unit, the device variants XR524-8C and XR526-8C require
little space in the cabinet. Both devices are suitable for fanless operation and redundant
power supply. Eight of the twenty four ports are designed as combo ports, the can have
pluggable transceivers fitted therefore providing electrical or optical interfaces as required.

SCALANCE W devices
Introduction
All SCALANCE W products were developed specially for industrial use. Thanks to the robust
housing and high reliability in data transmission, the devices are suitable for all sectors and
applications. With most of the devices, the power supply can also be via Power over
Ethernet. This allows these devices to be integrated in an existing infrastructure without
additional cabling. The accessories such as antennas, power supply units and cabling are
also part of this concept and produced to be suitable for industry. The exchangeable media
C-PLUG (configuration plug) and KEY-PLUG store project engineering and configuration
data which makes device replacement possible in a short time without specially trained
personnel. This minimizes downtimes and saves training costs. Over and above this, the
KEY-PLUG releases further device properties (known as "iFeatures").
To protect against unauthorized access, the products provide modern standard mechanisms
for user identification (authentication) and encryption of data, and can be easily integrated
into existing security concepts at the same time.
With the international standard IEEE 802.11n wireless communication becomes even more
robust. The greatest advantage results from the use of multipath propagation (Multiple Input,
Multiple Output (MIMO)). This makes it possible for the devices to use multiple antennas at
the same time. This achieves a higher data rate and at the same time reduces the
susceptibility to disturbances in environments with a lot of reflections.
● Access points
Access points are the central base stations for infrastructure networks. They coordinate
and control the wireless traffic within a wireless cell. If there are two or more access
points in a wireless network, i.e. same wireless network name (SSID), the client module
can move between the wireless cells formed by the individual access points (roaming).
The wireless connection is retained during roaming. This technique is used when the
required wireless coverage is greater than the distance that can be covered by a single
access point. All access points can also be configured so that they are restricted to client
functionality.
● Client modules
Client modules of the SCALANCE W product line are used as gateways between
wireless and wired network segments (bridge function). Normally, they communicate with
an access point (infrastructure network). All access points - except the controller access
points - can also be configured as client modules.
● WLAN controller
The IWLAN controller SCALANCE W product line manages and coordinates controllerbased access points.

Functions of WLAN devices
Introduction
This section describes certain functions of SCALANCE W devices. For further information on
all the functions, refer to the operating instructions of the individual devices or the
configuration manual.

SCALANCE network components
4.5 SCALANCE W components for Industrial Wireless LAN
Authentication and encryption
Authentication and encryption protect a network from unauthorized access. This is achieved
by an exchange of keys or certificates between client and server. There are various methods
that are explained in detail in the SCALANCE W700 configuration manual and in the section
"Encryption and data security (Page 50)".
Support of IEEE 802.11n
With SCALANCE W700 devices that support IEEE 802.11n, a data throughput up to 450
Mbps (gross) is possible depending on the version. You will find detailed information in the
section "IEEE 802.11n (Page 46)". These devices also support the following functions:
● Frame aggregation
● Shortened guard interval
● Channel bonding
SCALANCE W devices as bridges
A bridge is a network component that connects two networks. A bridge is not dependent on
the protocol; management of the data packages is based on the physical address of the
network nodes, the MAC address. The SCALANCE W provides bridge functionality for
handling data exchange between wired and wireless Ethernet.
● Learning Table
SCALANCE W devices log the information about which MAC address can be reached
over which port in a learning table.
● NAPT: Network Address Port Translation
With Network Address Port Translation (NAPT) or Port Address Translation (PAT),
several internal source IP addresses are translated into the same external source IP
address. This function is only available on clients in client mode.
Special functions for industrial applications
The following functions are used especially in an industrial environment:
● IPCF: Industrial Point Coordination Function
iPCF is the functional expansion of the IEEE 802.11 standard for applications requiring
real time and a deterministic response (predictable reply times). This allows Rapid
Roaming of mobile nodes from one RF field to the next. Wireless and secure PROFINET
IO communication is also supported with the SIMATIC Mobile Panel 277F IWLAN.
● IPCF-MC: IPCF Management Channel
The iPCF Management Channel, iPCF MC, is a further development of iPCF. This mode
should be used when IWLAN nodes that also support iPCF MC are moving freely in the
RF field. This method is particularly suitable when using omnidirectional antennas, when
deterministic data needs to be exchanged.

SCALANCE W788 M12 access point
The access points W788-x RJ45/W788-x M12 and the client modules W748-1 RJ45/W748-1
M12 support the standard IEEE 802.11a/b/g/n. These devices are intended to set up
Industrial Wireless LAN (IWLAN) wireless networks for 2.4 GHz or 5 GHz.
The devices SCALANCE W788/W748 use three data streams and therefore achieve data
rates up to 450 Mbps. The high data rate is achieved among other things by channel
bonding and by 3 x 3 MIMO technology (Multiple Input, Multiple Output), see section IEEE
802.11n (Page 46) The devices each use three data streams for the simultaneous send and
receiving of wireless signals.
The access points SCALANCE W788-x RJ-45 and the client module SCALANCE W748-1
RJ-45 are particularly suitable for applications in which the access point is to be installed in
the cabinet. The robust aluminum housing of the SCALANCE W788 RJ-45 devices in degree
of protection IP30 provides protection from mechanisms and electromagnetic loads and is a
cost-effective alternative for use in indoors.
The access points SCALANCE W788-x M12 and the client module SCALANCE W748-1
M12 can be installed at locations with suitable wireless properties indoors also outside the
cainet. The housing with degree of protection IP65 and the connectors withstand high loads
caused by shock and vibration since all connections are screwed or lock in place.
The access point SCALANCE W788-2 M12 EEC also has an extended temperature range
and conformal coating. The maximum ambient temperature for operation of this device is 70
°C.

Antennas
4.5.9.1
How it works
How antennas work
The task of an antenna is to convert electrical current into electromagnetic waves and vice
versa. A basic distinction is made between separate and integrated antennas. Detached
antennas increase the reliability of wireless links by optimizing the transmit and receive
conditions because these antennas can be mounted at a location with optimum wireless
conditions.. The connection between the detached antenna and access point or client is via
a cable. The antennas operated directly on the device allow compact, low-maintenance
installation.
The antennas can communicate in the 2.4 GHz or 5 GHz frequency band or in both
frequency bands.
Two further related properties are important for any antenna:
● Radiation characteristics
The radiation characteristics describe how strong the directionality of an antenna is. You
have three options:
– Omnidirectional
Radiation is uniform in all directions of a spatial plane (horizontal or vertical,
depending on the position of the antenna).
– Directional
Radiation is predominantly in one direction in which the electromagnetic waves are
transmitted with higher intensity. In the other spatial areas, the field strength is
correspondingly weaker.
● Antenna gain
The antenna gain is the characteristic value for the directionality of an antenna. This
parameter is obtained by comparing the maximum radiated power of the antenna with the
power of an isotropic radiator. The antenna gain G is calculated in dBi according to the
following formula:
G = 10 * log (max. power density antenna / max. power density of an isotropic radiator)
Antennas with multiple connectors: Dual or MIMO antennas according to IEEE 802.11n
Dual antennas are antennas with two connectors. These are integrated in an antenna
housing as two individual antennas offset by 90° from each other or have a suitable
clearance to each other. These antennas can be used to transmit two data streams at the
same time.
MIMO antennas are antennas with three connectors. They contain three individual radiators
combined in one antenna housing and operating either in different polarization planes (0°, +/45°) or with a suitable clearance between them. The MIMO antennas can transmit three data
streams simultaneously making use of multipath propagation.
Transmitting multiple data streams increases the data throughput while at the same time
making data transfer more reliable.

4.5 SCALANCE W components for Industrial Wireless LAN
Radiating cable IWLAN RCoax cable
In environments that make the use of wireless difficult, or when the node only moves along
predefined rails, it is sometimes preferable to replace the omnidirectional antennas with an
RCoax radiating cable. The radiating cable is a special antenna in the form of a thick, flexible
cable that produces an RF field with high intensity but only over a very limited range. As long
as it can be guaranteed that the communication partner moves in an area close to the
RCoax cable, the radiating cable provides a reliable RF field and an excellent connection to
the nodes.
● Reliable coverage in difficult wireless areas, for example cranes,
● High-bay loader units, production lines, tunnels or overhead monorails
● Generation of a cone-shaped limited RF field
● Low interference or mutual disturbance due to low transmit power
● Cost saving due to direct substitution of sliding contacts and trailing cables
● Highly flexible application

SCALANCE M devices
Areas of application for SCALANCE M and components of GPRS
The widespread availability of GPRS (General Packet Radio Service) the expansion of LTE
and advantageous volume tariffs allow wireless connection of stations to a control center in
many countries without users needing to set up their own wireless network. The stations can
be either stationary or mobile.
The online wireless connection is permanently available and provides properties similar to
those of a dedicated line. Data changes can be transferred immediately and station or
connection failures are detected and localized in a very short time.
Among others, the following systems can be controlled and monitored with the SCALANCE
M devices:
● Sewage works, water treatment
● Oil and gas supply
● District heating networks
● Energy distributors
● Pumping stations
● Traffic control technology
● Building
● Wind energy and photovoltaic systems
● Machines
● Electronic advertising boards
● Weather stations
● Lighthouses and buoys
GPRS / UMTS / LTE for complex stations with increased security requirements
GPRS, UMTS and LTE packet oriented mobile communications services. With their high
high transmission speeds, UMTS and LTE allow fast communication and are suitable above
all for mobile Internet access. Devices like the SCALANCE M874-x or the SCALANCE
M876-x combine the functionality of a VPN router with higher data security (IPsec protocol)
and firewall. Via Industrial Ethernet other devices connected to the SCALANCE M_800 can
be reached from a master station for diagnostics and parameter assignment.
A control center PC must be reachable constantly from the mobile wireless network. To
achieve this, it is connected directly to the mobile wireless provider via a dedicated line or
permanently to the Internet, for example using DSL. A SCALANCE S612 or SCALANCE
S623 security module takes over the firewall function in the control center and represents the
partner for the VPN connections of the GPRS stations. The VPN configuration is performed

with the SIMATIC NET "Security Configuration Tool" and allows configuration without special
IT experience. The IP address of the master station should ideally be fixed, those of the
stations can be assigned dynamically.
Wired communication via public od the company's own networks
The modules SCALANCE M812-1, SCALANCE M816-1 and SCALANCE M826-2 allow the
connection of stations via wired networks. This can either be public or the company's own
communications infrastructure. When a station is connected to to the Internet via ADSL, the
Internet services are available to you. For example a device can send an e-mail if an alarm
event occurs. The SCALANCE M devices for wired communication also have proven
security functions (firewall with stateful packet inspection, VPN, IPsec etc.).
If stations are connected cia the company's own 2-wire copper cables, point-to-point and
linear bus structures can be set up. The SCALANCE M826-2 device supports not only 2-wire
but also 4-wire operation. With this two 2-wire cables are aggregated to form a virtual
connection which allows the data rate to be doubled.

SCALANCE S security module
4.7.1
Introduction
Areas of application of SCALANCE S
The SCALANCE S security modules protect nodes connected to the protected network with
a combination of different security measures. SCALANCE S devices have different
protective functions and individual devices or even entire automation cells can be integrated
into the protected area. The security modules can be operated not only in bridge mode but
also in router mode. This means that the security modules are used directly at IP subnet
boundaries. There are different product variants to meet specific requirements such as the
use of FO cables or standby mode. For secure remote access via Internet, suitable devices
of the SCALANCE M800 series are available.
SCALANCE S is optimized for use in an automation or industrial environment. It meets the
specific requirements of automation engineering, for example easy upgrading of existing
systems, simple installation and minimum downtimes if a fault occurs.
Advantages of the cell protection concept:
● Protection from data espionage and data manipulation
● Protection against overload of the communications system
● Protection from external influences
● Protection from addressing errors
● Secure remote access via Internet
● Changes to or adaptation of the existing network structure are not necessary.
● Changes to or adaptation of the existing applications or network nodes are not necessary.

application that allows secure access to automation systems protected by SCALANCE S.
Figure 4-42

Example of a topology: Protection of an automation cell with a SCALANCE S612
Technical basics
Internal and external network nodes
SCALANCE S devices divide networks into two areas:
● Internal network: Protected areas with the "internal nodes".
Internal nodes are the nodes protected by a SCALANCE S device.
● External network: Unprotected areas with the "external nodes".
External nodes are all the nodes located outside the protected areas.
The internal network is considered to be secure and trustworthy. Connect an internal
network segment to the external network segments only over a SCALANCE S device. There
must be no other paths connecting the internal and external networks.
Configuration and administration
A CD ships with the SCALANCE S modules containing not only the manual but also the
Security Configuration Tool.
The Security Configuration Tool is designed for the following tasks:
● For configuration of the SCALANCE S security modules.
● For configuration of the SOFTNET Security Client (not possible for SCALANCE S602).
● For test and diagnostics functions and status displays.
To operate the SCALANCE S modules, you need to download a configuration created with
the Security Configuration Tool. The configuration of a SCALANCE S module involves the IP
parameters and the configuration of the firewall rules. With all devices except the
Industrial Ethernet
System Manual, 05/2016, C79000-G8976-C242-08
207
SCALANCE network components
4.7 SCALANCE S security module
SCALANCE S602, it is also possible, when necessary, to configure IPsec tunnels. For the
SCALANCE S602 router operation can be configured.
Firewall
The firewall functionality of SCALANCE S security modules protects the internal network
from influences or disturbances from external networks. This means that; depending on the
configuration, only certain specified communication relations between the network nodes
from the internal network and network nodes of the external networks are allowed. All
network nodes located in the internal network segment of a SCALANCE S security module
are protected by its firewall.
The firewall functionality can be configured for the following protocol levels:
● IP firewall incl. stateful inspection
● Firewall for Ethernet "non-IP" frames according to IEEE 802.3; (layer 2 frames)
The stateful inspection firewall (also known as Stateful Packet Filter or Dynamic Packet
Filter) is a firewall technology that operates both on the network and at the application layer.
The IP packets are accepted on the network layer, checked according to their state by an
analysis module and compared with a status table. For the communication partner, a firewall
with stateful inspection appears as a direct connection that only allows communication
according to the rules.
Firewall rules are the rules for data traffic in the following directions:
● From the internal to the external network and vice versa,
● from the internal network into an IPsec tunnel and vice versa (not possible with the
SCALANCE S602).
For all devices, user-specific firewall rules can also e specified. This means a predefined set
of rules that is assigned at the login user-dependent for a limited time.
SCALANCE S in routing mode
If SCALANCE S modules are operated in routing mode, they separate the internal network
from the external network based on the evaluation of the IP addresses. The internal network
separated by SCALANCE S602 therefore becomes a separate subnet.
Industrial Ethernet
208
System Manual, 05/2016, C79000-G8976-C242-08
SCALANCE network components
4.7 SCALANCE S security module
The following options are available:
● Routing can be configured in standard mode and advanced mode.
Frames intended for an existing IP address in the subnet (internal or external) are
forwarded. The firewall rules for the direction of transmission also apply. For this mode,
you must also configure an IP address for the internal subnet.
Note
In contrast to the bridge mode of the SCALANCE S security modules, VLAN tags are lost
in routing mode.
● NAT/NAPT routing can be configured in the advanced mode.
In this mode, the IP addresses are also translated. The IP addresses of the devices in the
internal subnet are translated to external IP addresses and are therefore "invisible" in the
external network.
SCALANCE S as DHCP server
A DHCP server assigns an IP address to each client throughout the network. DHCP
(Dynamic Host Configuration Protocol) in conjunction with a suitable server, allows the
dynamic assignment of an IP address and other configuration parameters to computers
within the network. SCALANCE S security modules can be operated in the internal network
as DHCP servers. This allows IP addresses to be assigned automatically to the devices
connected to the internal network. The IP addresses are assigned either dynamically from a
defined range of addresses or a specific device is assigned a specific IP address according
to the definition.
Testing, diagnostics, logging and Syslog
For testing and monitoring, the Security Configuration Tool (SCT) has diagnostics and
logging functions.
● Diagnostics functions
In online mode various system and status functions can be used for diagnostics.
● Logging functions
The system and security events are logged. The events are logged in the buffer areas of
the security module (local logging) or of a server (network Syslog). You select the events
to be logged in the log settings for the relevant security module.
IPsec tunnel (not possible for the SCALANCE S602)
IPSec the short form of Internet Protocol Security is a layer 3 tunneling protocol. It is
supported by all SCALANCE S devices except the SCALANCE S602. The IPsec tunnel
provides the nodes with a secure data connection through the non-secure external network
to other devices protected by the SCALANCE S modules.
Industrial Ethernet

SCALANCE network components
4.7 SCALANCE S security module
The encryption of the data transmission with VPN (IPsec) provides the following:
● Protection against espionage: The data exchanged is safe from eavesdropping (ensuring
confidentiality).
● Protection against manipulation: The data exchanged is safe from
corruption/counterfeiting (ensuring the integrity).
● Authenticity: Only authorized nodes can establish a tunnel (ensuring the legitimacy of the
communication).
The Security Configuration Tool also allows the configuration of Virtual Private Networks
(VPN). To do this SCALANCE S modules as well as the SOFTNET Security Client modules
integrated in an internal network are put together in groups in the configuration. IPsec
tunnels are established automatically between the SCALANCE S modules and SOFTNET
Security Client modules that belong to the same group. Tunneling also includes Ethernet
frames according to the IEEE standard 802.3 (layer 2 frames). Both IP and non-IP frames
are transmitted through the IPsec tunnel.
4.7.3
Description
SCALANCE S devices are available in different housing designs (metal or plastic housing)
and port configurations. Configuration and engineering data is stored in internal non-volatile
memory. As an options, storage on a C-PLUG is also possible. If a SCALANCE S device
needs to be replaced, the configuration data can be transferred simply to the new device.

The two Industrial Ethernet connectors, port 1 and port 2 are handled differently by
SCALANCE S modules. For this reason, these interfaces must not be confused when
connecting to the communications network.
● Port 1: External network
Marked red, this interface is for the unprotected network area.
● Port 2: Internal network
Marked green, this interface is intended for the network area protected by SCALANCE S.
The same applies to ports P4 to P7 of the optional media modules of the SCALANCE S6272M. With the SCALANCE S615 there is no color marking of the ports because the
assignment of a port to the external or internal network can be freely configured.
Note
If these marked ports are swapped over, the devices lose their protective function.

SOFTNET Security Client
Description
The SOFTNET Security Client is a software application that serves as an integral part of the
Industrial Security concept to protect programmable controllers. This ensures security when
data is exchanged between programmable controllers and entire automation systems or
automation cells.
● The SOFTNET Security Client application is available as a VPN client for programming
devices, PCs and notebooks in an industrial environment. The application allows secure
client access via LAN or also via WAN to automation systems protected with SCALANCE
S functionality. For example remote maintenance via the Internet.
● Protection of the data transfer from incorrect operator input, eavesdropping / espionage
and manipulation.
Communication is only possible between authenticated and authorized devices.
● The SOFTNET Security Client uses proven IPsec mechanisms to establish and operate
Virtual Private Networks (VPNs).
● End-to-end intuitive configuration without specialist security knowledge.
● A common configuration tool with a common database for SCALANCE S modules and
the SOFTNET Security Client.
– Automatic generation of the certificates by the Security Configuration Tool.
– Automatic identification of the nodes of the internal network and detection of
SCALANCE S modules in the external network.
Principle of the application
Withe the PC software SOFTNET Security Client, VPN services are made available on the
PG or notebook. This makes secure IP-based access from the PC / PG to programmable
controllers possible that are protected by SCALANCE S612 or SCALANCE S623.

Details
● Easy handling due to minimum configuration
● No specialist knowledge of IT security is necessary.
● Changes to or adaptation of the existing network structure are not necessary.
● Automatic generation of the certificates by the configuration tool.
● Little configuration effort due to automatic identification of the nodes of the internal
network and detection of other security modules in the external network.
Benefits
● The secure access from programming devices or notebooks to complete automation cells
/ systems.
● The simple use of mobile PCs.
● The protection of data transfer from espionage and manipulation using certified
standards.
● Devices classified as not secure can be included in the secure data traffic.
Area of application - access via VPN
With the SOFTNET Security Client, a PC/PG is configured automatically so that it can
establish IPsec tunnels to one or more SCALANCE S modules.
This communication via these IPsec tunnels makes it possible for PG/PC applications such
as NCM (Network and Communication Management) diagnostics or with STEP 7 to securely
access devices or networks that are located in an internal network protected by SCALANCE
S.
Note
Note that you can only use the SOFTNET Security Client in groups with modules in the
active bridge mode.
Automatic communication via VPN
For your application, it is important that the SOFTNET Security Client automatically detects
when there is access to the IP address of a VPN node. The nodes are addressed via the IP
address as if they were in the local subnet to which the programming device / PC is also
connected with this application.
How it works
The SOFTNET Security Client reads in the configuration created by the Security
Configuration Tool and obtains the required information on the certificates to be imported
from the relevant file. The root certificate and the private keys are imported and stored on the
local PG / PC. Following this, security settings are made based on the data from the
configuration so that applications can access IP addresses downstream from the
SCALANCE S modules.
Industrial Ethernet
216

SCALANCE network components
4.7 SCALANCE S security module
If a learning mode for the internal nodes or programmable controllers is enabled, the
configuration module first sets a security policy for the secure access to the SCALANCE S
modules. The SOFTNET Security Client then addresses the SCALANCE S modules to
obtain the IP addresses of the relevant internal nodes. The SOFTNET Security Client
registers these IP addresses in special filter lists belonging to this security policy. Following
this, applications such as STEP 7 can communicate with the programmable controllers via
VPN.

SINEMA server
Introduction
The SINEMA Server software was specifically developed for industrial applications. By using
SNMP for all classic network components and by evaluating SIMATIC and PROFINET
modules in the automation environment, networks can be fully analyzed and monitored. The
acquired data is stored in a long-term archive and can be evaluated as necessary and
shown in reports. The acquired network diagnostics can also be integrated seamlessly via
OPC and Web mechanisms in HMI/SCADA systems (e-g. WinCC, PCS 7).
Note
You will find more detailed information on SINEMA Server in SINEMA
(http://www.siemens.com/sinema)
Features and functions
● Simple operability
All the user interfaces are designed to make operation simple and clear. Complex training
can therefore be greatly reduced.
● Automatic detection of all components in the network
Via SNMP but also by reading out PROFINET data produces clear lists of all the
components in the network. Apart from the classic I&M data, here detailed information
e.g. on PROFINET properties, redundancy protocols or WLAN status can be read out
and displayed.
● Clear representation of the network topology
The topology of a network is read out using SNMP and PROFINET and displayed clearly.
Topologies can be displayed in detail or in a structural icon view.
● Event-based message system for transparent presentation of the network diagnostics
The network is monitored continuously and the user is informed of status changes (e.g.
redundancy errors, PROFINET diagnostics, bad frames).
● SIMATIC diagnostics (S7-300, S7-400)
By reading out and monitoring cycle times or the evaluation of specific SIMATIC
diagnostics, the classic network diagnostics can be enriched with applicative SIMATIC
diagnostics.
● PROFINET diagnostics
By using PROFINET, the diagnostics of modules does not end at their Ethernet interface.
The applicative status of a PROFINET module now provides detailed status information.
● Standardized network documentation (reports), even over longer periodsReports are
available for a wide range of evaluations (availability, performance, device inventory,

events). Thanks to the database-based architecture evaluations can be made over long
periods of the past.
● User-based adaptation of the user interfaces
The user and user group management allows users with staggered rights to be managed.
Users can not only be assigned different rights but also different plant areas. User
interface settings are also stored for specific users.
● Access possible via every standard browser
SINEMA Server is Web-based application. This has the advantage that up to 20 users
can connect to the server at the same time. For this, a local Internet browser is adequate.
● Multiple server status view "Server Overview"
With the "Server Overview" function, the status of up to 100 servers can be displayed.
Trend graphs provide detailed information of the diagnostics development of servers.
● Export of data by CSV for multiple server evaluation
With a URL call, information (as CSV) of many servers can be queried. This makes it
possible to bundle and evaluate cross-server data.
● Profile concept for integration of any network nodes
Using profiles that can be adapted to your own requirements, it is possible to make any
network components known in SINEMA Server. Profiles can be imported/exported
manually or loaded automatically with "Device profile synchronization".
● HMI connection via URL and OPC server
To integrate diagnostics data from SINEMA Server in an HMI system, there is a flexible
URL mechanism and a fully fledged OPC server available.

Primary Setup Tool
Description
With the Primary Setup Tool (PST), an address assignment (for example an IP address) is
made via the network for unconfigured SIMATIC NET network components, Ethernet CPs
and gateways. This is only possible if the SIMATIC NET devices have a default ETHERNET
(MAC) address and can be reached online in the network. The nodes must also support the
DCP protocol. The PST uses a filter view to allow a clear presentation of modules and
devices.
Note
The Primary Setup Tool supports only SIMATIC NET Ethernet network components with
management functionality (Web-based Management and/or SNMP). With these
components, you also have the option of calling Web-based Management for diagnostics
and configuration.

C-PLUG Configuration Memory
Description
The C-PLUG is an exchangeable medium for storage of the configuration and project
engineering data of the base device. This means that the configuration data remains
available if the basic device is replaced. It is therefore used when the replacement of
network components or communications modules needs to be quick if a fault occurs without
needing to configure a replacement and without needing specialist personnel. Downtimes of
network segments and connected Industrial Ethernet nodes can therefore be minimized if a
fault occurs.
It can be used in all SIMATIC NET products with a C-PLUG slot.
Structure
The C-PLUG has degree of protection IP20. With IP65 components, the protection is
retained because the C-PLUG is installed inside the protected housing.
Power is supplied by the end device. The C-PLUG retains all data when the power is turned
off.
Function
If an empty CPLUG (as supplied) is inserted in a SIMATIC NET component, the device
automatically backs up the configuration data during startup. Changes to the configuration
during operation are also saved on the C-PLUG without any additional operator intervention
being necessary.
When an unconfigured device starts up, it automatically adopts the configuration data of an
inserted C-PLUG assuming the data was written by a compatible device type.
The C-PLUG can also be used to store application data such as documentation or Web
pages.

Application
Communications processors for PCs/PGs allow you to establish a connection to industrial
Ethernet with a PC/PG or a SIMATIC Microbox PC (PCI-104 interface). There are two
categories of communications processors for PCs/PGs:
● Communications processors with their own microprocessor.
This relieves the PC/PG CPU. This frees up computing power on the PC for other
applications, for example HMI (ISO and TCP/IP transport on board).
● Communications processors without their own microprocessor.
These communications processors are less expensive than the communications
processors that have their own microprocessor. If there is, however, heavy load on the
PC microprocessor, it is possible that the protocol stack does not receive a time slice and
this leads to the connection being terminated. When using communications processors
with their own microprocessor, this does not occur.

Description
For each SIMATIC S7 system, there are communications processors (CPs) that provide a
connection to Industrial Ethernet. This means that S7 controllers can exchange data with
other network nodes via Industrial Ethernet. These network nodes can be other S7CPs/CPUs or PCs with an Ethernet card. This allows remote programming and diagnostics
via the PG/PC. With the communications processors that support PROFINET, PROFINET
IO-compliant field devices can be addressed directly.
SIPLUS
For applications in harsh environmental conditions, in aggressive environments or in extreme
temperature ranges, the standard properties of an individual device or system are often
inadequate. Due to deployment in such locations, there may be restrictions to the
functionality or operational reliability and even total failure of a system.
The product types designed to meet such requirements are identified by 'SIPLUS' being
appended to the name. The products are certified according to EN 60721-3C4, -3S4, -3B2
as well as ISA S71.04-G1, -G2, -G3 and -GX.
The modules are designed for use in humidity of up to 100%, condensation and salty
atmospheres due to conformal coating. These properties also protect the products from
dendrite formation and micro corrosion.
Based on the industrial automation system SIMATIC S7-300, two upgraded SIPLUS
versions are available.
● For an expanded temperature range of -25 °C to +60 °C and some devices up to +70 °C.
● Unusual environmental load (conformal coating) and electronic equipment on rolling stock
conforming with EN 50155.

CP 443-1 RNA
The CP 443-1 RNA is designed to connect a SIMATIC S7-400 system to Industrial Ethernet
networks. The special feature of this device is support of the redundancy protocol PRP
(Parallel Redundancy Protocol). This allows the connection of devices to redundant Ethernet
networks. In addition to this fault-tolerant systems (known as H systems) are supported. The
device has the following characteristics and functions:
● Time-of-day synchronization over the RNA interface using the following configurable
methods:
– SIMATIC mode
The CP receives MMS timeofday messages and synchronizes its local time.
You can choose whether or not the time of day is forwarded. You can also decide on
the direction in which it is forwarded.
or
– NTP mode (NTP: Network Time Protocol)
The CP sends timeofday queries at regular intervals to an NTP server and
synchronizes its local time of day.
The time can also be forwarded automatically to the CPU modules in the S7 station
allowing the time to be synchronized in the entire S7 station.
● Addressable with the factoryset MAC address
To assign the IP address to a new CP (direct from the factory), it can be accessed using
the preset MAC address on port X2P1 of the RNA interface. The online address
assignment is made in STEP 7.
● SNMP agent on the RNA interface
The CP supports data queries via SNMP in version V1 (Simple Network Management
Protocol). It delivers the content of certain MIB objects according to the MIB II standard
(RFC 1213), PRP-MIB IEC62439 (IEC-62439-3-MIB) and Automation MIB.
● Module access protection
To protect the module from accidental or unauthorized access, protection can be
configured at various levels.
● IP access protection on the RNA interface (IP-ACL)
Using IP access protection gives you the opportunity of restricting communication over
the CP of the local S7 station to partners with specific IP addresses.
● Web diagnostics on the RNA interface
With the aid of Web diagnostics, you can read out the diagnostics data from a station
connected via the CP to a PG/PC with a Web browser.
The Web pages contain the following information:
– Module and status information
● Diagnostics buffer extract request
With the aid of a Web browser, the CP supports the option of obtaining an extract of the
diagnostics buffer containing the most recent diagnostics events of the CPUs and CPs
located in the same S7 station as the CP.

● Connection diagnostics with the AG_CNTEX program block
With the AG_CNTEX program block, you can diagnose connections.
– When necessary, you can activate or deactivate connections or initiate
reestablishment of a connection.
– You can check the reachability of the connection partners using the PING function (on
the RNA interface).
– You can find out which connection types are set up on the RNA interface for the
SEND / RECEIVE function.
● S5/S7 addressing mode
The addressing mode can be configured for FETCH/WRITE access as the S7 or S5
addressing mode (S7 addressing mode only for data blocks / DBs).
● Detecting IP double addressing in the network on the RNA interface
To save you timeconsuming troubleshooting in the network, the CP detects double
addressing in the network.
● Support in the fault-tolerant system (H system)
S7 communication is supported in the H system with the following protocols:
– Ethernet interface
ISO transport
– RNA interface

Description
The Compact Switch Modules are industrial Ethernet switches with a compact, modular
design for use in the immediate vicinity of the SIMATIC S7 CPUs. Using a CSM, the
Ethernet interface of a SIMATIC S7 CPU can be multiplied. This means that simultaneous
communication with operator control and programming devices, other controllers or office
networks is possible.
With a CSM and the SIMATIC S7 controller, simple, low-cost automation networks can be
implemented.

general requirements in and between automation cells
IEC61784-5-x
International series of standards for special
requirements in industrial networks such as
PROFINET / PROFIBUS, supplementing
IEC 61918
Describes specific requirements of
the communication profile
1)
Fieldbus-specific aspects are described in separate, ancillary standards
The "PROFINET Cabling and Interconnection Technology" guideline
Among other things, the PROFIBUS User Organization has produced the "PROFINET
Cabling and Interconnection Technology" guideline that served as input for IEC 61918 and
IEC 61784 and that also references these standards.
It describes the technical benchmark values for cables and connectors (both electrical and
optical) for PROFINET networks. These are intended to help new manufacturers to produce
PROFINET-compliant products.
The guideline can be downloaded in English from the URL:

A.2 Content of the standards
A.2
Content of the standards
Content of the IEC 24702 and EN50173-3 standards
The standards for general purpose building networking of buildings used for industrial
purposes describe:
● The structure of the building network,
● The requirements for cables (fibre-optic, electrical),
● The requirements for connectors (fibre-optic, electrical),
● Limit values for installed links.
IEC 24702 references IEC11801.
Technical aspects of installation described in IEC 14763 (EN50174).
Content of the IEC 61918 and IEC61784 standards
the standards for automation networks include a general section describing the following
points:
● Design of the network (network structure, grounding, equipotential bonding),
● Planning and installation,
● Requirements of components (table connectors, cables, grounding, ...)
● Acceptance of an installation,
● Maintenance and service.
IEC 61918 contains general requirements common to all fieldbuses (PROFINET, PB,
Interbus,…).
Fieldbus-specific aspects/requirements that differ from the general section described in
profile-specific standards, for example in IEC61784-5-3 for PROFIBUS, PROFIBUS PA and
PROFINET; IEC61784-5-6 for Interbus.
