Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, solutions, machines, equipment and/or networks. They are
important components in a holistic industrial security concept. With this in mind, Siemens’
products and solutions undergo continuous development. Siemens recommends strongly that
you regularly check for product updates.
For the secure operation of Siemens products and solutions, it is necessary to take suitable
preventive action (e.g. cell protection concept) and integrate each component into a holistic,
state-of-the-art industrial security concept. Third-party products that may be in use should also
be considered. For more information about industrial security, visit http://www.siemens.com/

The following and possibly other names not identified by the registered trademark sign ® are
registered trademarks of Siemens AG:
SIMATIC NET, SCALANCE, C-PLUG, OLM
The firmware is signed and encrypted. This ensures that only firmware created by Siemens
can be downloaded to the device.
● The Ethernet interfaces support the following modes:
– 10 Mbps and 100 Mbps both in full and half duplex
– 1000 Mbps full duplex
– Autocrossing
– Autopolarity
● Redundancy protocols Multiple Spanning Tree Protocol (MSTP), Rapid Spanning Tree
Protocol (RSTP) and Spanning Tree Protocol (STP)
This means part of a network can be connected redundantly to a higher-level company
network. The reconfiguration time of the network is in the seconds range and therefore
takes longer than the ring redundancy method.
● Virtual networks (VLAN)
To structure Industrial Ethernet networks with a fast growing number of nodes, a physical
network can be divided into several virtual subnets. Port-based, protocol-based and subnetbased VLANs are available.
2
Layer 3 functions
● Load limitation when using multicast protocols, for example video transmission
By learning the multicast sources and destinations (IGMP snooping, IGMP querier), the IE
switches can filter multicast data traffic and limit the load in the network. Multicast and
broadcast data traffic can be limited.
● Time-of-day synchronization
Diagnostics messages (log table entries, e-mails) are given a time stamp. The local time
is uniform throughout the network thanks to synchronization with a SICLOCK time
transmitter or SNTP/NTP/PTP server and therefore makes the identification of diagnostics
messages of several devices easier.
● Link aggregation (IEEE 802.1AX) for bundling ports
● Quality of Service for classification of the network traffic is according to COS (Class of
Service - IEEE 802.11Q) and DSCP (Differentiated Services Code Point - RFC 2474)
The following functions are only available on devices with routing functions:
● Static routing
● OSPF / OSPFv3
● VRRP / VRRPv3
● RIP / RIPng

Naming interfaces
Interface names with SCALANCE XM-400
● Interfaces of the basic device
The interfaces of the basic device SCALANCE XM-400 are called module 1.
● Interfaces of extenders
The port extenders are called module 2 and module 3 starting from the basic device. The
number of port extenders depends on the number of ports of the basic device.
The extender function is called module 0.
Combo ports
Interface names with SCALANCE XR-500
● Permanently integrated Interfaces
The interfaces permanently installed in the SCALANCE XR-500 are identified with module
0.
● Interfaces of modules
The slots for modules are called module 1 followed by numbers. The numbering range
depends on the hardware configuration. The numbering is fixed and does not depend on
the number of modules being used.
Each module has 4 ports numbered 1 to 4.
Combo port is the name for two communication ports. A combo port has the two following plugin options:
● a fixed RJ-45 port
● an SFP transceiver slot that can be equipped individually
Of these two ports, only one can ever be active.
You can set the active port on the WBM page "System > Ports > Configuration"with the CLI
command media-type.
Requirements for installation and operation of the IE switches
A PG/PC with a network connection must be available in order to configure the IE switches. If
no DHCP server is available, a PG/PC on which the Primary Setup Tool (PST) is installed is
necessary for the initial assignment of an IP address to the IE switches. For the other
configuration settings, a PG/PC with Telnet or an Internet browser is necessary.
Serial interface
The IE switches have a serial interface. An IP address is unnecessary to be able to access
the device via the serial interface. A serial cable ships with the products.
Set the following parameters for the connection:
● Bits per second: 115200
● Data bits: 8
● Parity: None
● Stop bits: 1
Description
2.3 C-PLUG / KEY-PLUG
● Flow control: None
2.3C-PLUG / KEY-PLUG
Configuration information on the C-PLUG / KEY-PLUG
The C-PLUG / KEY-PLUG is used to transfer the configuration of the old device to the new
device when a device is replaced.
NOTICE
Do not remove or insert a C-PLUG / KEY-PLUG during operation!
A C-PLUG / KEY-PLUG may only be removed or inserted when the device is turned off.
The device regularly checks whether or not a KEY-PLUG is present. If it is detected that the
KEY-PLUG was removed, there is a restart. If a valid KEY-PLUG was inserted in the device,
the device changes to a defined error state following the restart.
When the new device starts up with the C-PLUG / KEY-PLUG, it then continues automatically
with exactly the same configuration as the old device. One exception to this can be the IP
configuration if it is set over DHCP and the DHCP server has not been reconfigured accordingly.

Description
2.4 Power over Ethernet (PoE)
A reconfiguration is necessary if you use functions based on MAC addresses.
Note
In terms of the C-PLUG / KEY-PLUG, the SCALANCE devices work in two modes:
● Without C-PLUG / KEY-PLUG
The device stores the configuration in internal memory. This mode is active when no CPLUG / KEY-PLUG is inserted.
● With C-PLUG / KEY-PLUG
The configuration stored on the C-PLUG / KEY-PLUG is displayed over the user interfaces.
If changes are made to the configuration, the device stores the configuration directly on the
C-PLUG / KEY-PLUG and in the internal memory. This mode is active as soon as a CPLUG / KEY-PLUG is inserted. When the device is started with a C-PLUG / KEY-PLUG
inserted, the device starts up with the configuration data on the C-PLUG / KEY-PLUG.
Note
Incompatibility with previous versions with C-PLUG / KEY-PLUG inserted
During the installation of a previous version of the firmware, the configuration data can be lost.
In this case, the device starts up with the factory settings after the firmware has been installed.
In this situation, if a C-PLUG / KEY-PLUG is inserted in the device, following the restart, this
has the status "Not Accepted" since the C-PLUG / KEY-PLUG still has the configuration data
of the previous more up-to-date firmware. This allows you to return to the previous, more upto-date firmware without any loss of configuration data. If the original configuration on the CPLUG / KEY-PLUG is no longer required, the C-PLUG / KEY-PLUG can be deleted or rewritten
manually.
License information on the KEY-PLUG
In addition to the configuration, the KEY-PLUG also contains a license that allows the use of
layer 3 functions.
2.4Power over Ethernet (PoE)
General
"Power over Ethernet" (PoE) is a power supply technique for network components according
to IEEE 802.3af or IEEE 802.3at. The power is supplied over the Ethernet cables that connect
the individual network components together. This makes an additional power cable
unnecessary. PoE can be used with all PoE-compliant network components that have a
maximum power consumption of max. 25.50 W.
In Fast Ethernet, the wire pairs 1, 2 and 3, 6 are used to transfer data. Pairs 4, 5 and 7, 8
are then used to supply power. If there are only four wires available, the voltage is
modulated onto the wires 1, 2 and 3, 6 (see variant 2). This alternative is suitable for a data
transmission rate of 10/100 Mbps. This type of power supply is not suitable for 1 Gbps since
with gigabit all eight wires are used for data transfer.
● Alternative B (phantom power)
With phantom power, the power is supplied over the pairs that are used for data transfer,
in other words, all eight (1 Gbps) or four (10/100 Mbps) wires are used both for the data
transfer and the power supply.
A PoE-compliant end device must support both alternative A and alternative B over redundant
wires.
A switch with PoE capability can supply the end device either using
● alternative A or
● Alternative B or
● alternative A and alternative B.
Description
2.4 Power over Ethernet (PoE)
Endspan
Midspan
Note
The SCALANCE PE408PoE extender supports alternative B.
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, for example a SCALANCE X108PoE, SCALANCE
X308-2M PoE, all SCALANCE XM400 switches with PE408PoE, SCALANCE XR552‑12M.
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.
A Siemens power insert can also be used as the interface for the power input. Since a power
insert supports a power supply of 24 VDC, it does not conform with IEEE 802.3af or IEEE
802.3at. The following restrictions relating to the use of power inserts should be noted:
WARNING
Operate the power insert only when the following conditions apply:
● with extra low voltages SELV, PELV complying with IEC 60364-4-41
● in USA/CAN with power supplies complying with NEC class 2
● in USA/CAN, the cabling must meet the requirements of NEC/CEC
● Current load maximum 0.5 A

ClassCIDR
An IP address consists of 4 bytes. Each byte is represented in decimal, with a dot separating
it from the previous one. This results in the following structure, where XXX stands for a number
between 0 and 255:
XXX.XXX.XXX.XXX
The IP address is made up of two parts, the network ID and the host ID. This allows different
subnets to be created. Depending on the bytes of the IP address used as the network ID and
those used for the host ID, the IP address can be assigned to a specific address class.
Subnet mask
The bits of the host ID can be used to create subnets. The leading bits represent the address
of the subnet and the remaining bits the address of the host in the subnet.
A subnet is defined by the subnet mask. The structure of the subnet mask corresponds to that
of an IP address. If a "1" is used at a bit position in the subnet mask, the bit belongs to the
corresponding position in the IP address of the subnet address, otherwise to the address of
the computer.
Example of a class B network:
The standard subnet address for class B networks is 255.255.0.0; in other words, the last two
bytes are available for defining a subnet. If 16 subnets must be defined, the third byte of the
subnet address must be set to 11110000 (binary notation). In this case, this results in the
subnet mask 255.255.240.0.
To find out whether two IP addresses belong to the same subnet, the two IP addresses and
the subnet mask are ANDed bit by bit. If both logic operations have the save result, both IP
addresses belong to the same subnet, for example, 141.120.246.210 and 141.120.252.108.

IP addresses
3.2 IPv4 address
Outside the local area network, the distinction between network ID and host ID is of no
significance, in this case packets are delivered based on the entire IP address.
Note
In the bit representation of the subnet mask, the "ones" must be set left-justified; in other words,
there must be no "zeros" between the "ones".
3.2.2Initial assignment of an IPv4 address
Configuration options
An initial IP address for an IE switch cannot be assigned using Web Based Management
(WBM) because this configuration tool can only be used if an IP address already exists.
The following options are available to assign an IP address to an unconfigured device:
● DHCP (default)
● Primary Setup Tool (PST)
– To be able to assign an IP address to the IE switch with the PST, it must be possible to
reach the device via Ethernet.
– You will find the PST on the Internet pages of Siemens Industry Online Support under
the entry ID 19440762 (
19440762).
– For further information about assigning the IP address with the PST, refer to the
documentation "Primary Setup Tool (PST)".
● STEP7
In STEP 7, you can configure the topology, the device name and the IP address. If you
connect an unconfigured IE switch to the controller, the controller assigns the configured
device name and the IP address to the IE switch automatically.
– STEP 7 as of V5.5 SP4
For further information on the assignment of the IP address using STEP 7 refer to the
documentation "Configuring Hardware and Connections with STEP 7", in the section
"Steps For Configuring a PROFINET IO System".
– STEP 7 Basic as of V12 SP1 or STEP 7 Professional as of V12 SP1
For further information on assigning the IP address using STEP 7 (as of V12 SP1), refer
to the online help "Information system", section "Addressing PROFINET devices".
● CLI via the serial interface
For further information on assigning the IP address using the CLI, refer to the
documentation "SCALANCE XM-400/XR-500 Command Line Interface".
For further information on assigning the IP address using NCM PC, refer to the
documentation "Commissioning PC stations - Manual and Quick Start", in the section
"Creating a PROFINET IO system".
● RUGGEDCOM EXPLORER
With the RUGGEDCOM EXPLORER you can recognize devices in a network and make
the following basic settings:
– IP Address
– Subnet Mask
– Default Gateway
– System Name
– Device Location
– System Contact
The RUGGEDCOM EXPLORER can run on every LAN-based MS Windows-PC.
To be able to use the RUGGEDCOM EXPLORER, RCDP (RUGGEDCOM Discovery
Protocol) must be enabled on the device.
You will find more information on the RUGGEDCOM EXPLORER here:
– On the Internet pages of Siemens Industry Online Support (https://
When the product ships and following "Restore Factory Defaults and Restart", DHCP is
enabled. If a DHCP server is available in the local area network, and this responds to the DHCP
request of an IE switch, the IP address, subnet mask and gateway are assigned automatically
when the device first starts up.
3.2.3Address assignment with DHCP
Properties of DHCP
DHCP (Dynamic Host Configuration Protocol) is a method for automatic assignment of IP
addresses. It has the following characteristics:
● DHCP can be used both when starting up a device and during ongoing operation.
● The assigned IP address remains valid only for a limited time known as the lease time.
When half the period of validity has elapsed. the DHCP client can extend the period of the
assigned IPv4 address. When the entire time has elapsed, the DHCP client needs to
request a new IPv4 address.

Configuration Manual, 05/2017, C79000-G8976-C248-1225
IP addresses
3.3 IPv6 addresses
● There is normally no fixed address assignment; in other words, when a client requests an
IP address again, it normally receives a different address from the previous address. It is
possible to configure the DHCP server so that the DHCP client always receives the same
fixed address in response to its request. The parameter with which the DHCP client is
identified for the fixed address assignment is set on the DHCP client. The address can be
assigned via the MAC address, the DHCP client ID, PROFINET device name or the device
name. You configure the parameter in "System > DHCP Client (Page 173)".
● The following DHCP options are supported:
– DHCP option 3: Assignment of a router address
– DHCP option 6: Assignment of a DNS server address
– DHCP option 66: Assignment of a dynamic TFTP server name
– DHCP option 67: Assignment of a dynamic boot file name
– DHCP option 82: Assignment of IP addresses depending on the device index, switch
port, the VLAN ID or user-defined identification values of the DHCP relay agent.
Note
DHCP uses a mechanism with which the IP address is assigned for only a short time (lease
time). If the device does not reach the DHCP server with a new request on expiry of the
lease time, the assigned IP address, the subnet mask and the gateway continue to be used.
The device therefore remains accessible under the last assigned IP address even without
a DHCP server. This is not the standard behavior of office devices but is necessary for
problem-free operation of the plant.
3.3IPv6 addresses
3.3.1IPv6 terms
Network node
A network node is a device that is connected to one or more networks via one or more
interfaces.
Router
A network node that forwards IPv6 packets.
Host
A network node that represents an end point for IPv6 communication relations.
Link
A link is, according to IPv6 terminology, a direct layer 3 connection within an IPv6 network.
Neighbor
Two network nodes are called neighbors when they are located on the same link.
Physical or logical interface on which IPv6 is activated.
Path MTU
Maximum permitted packet size on a path from a sender to a recipient.
Path MTU discovery
Mechanism for determining the maximum permitted packet size along the entire path from a
sender to a recipient.
LLA
Link local address FE80::/10
As soon as IPv6 is activated on the interface, a link local address is formed automatically. Can
only be reached by nodes located on the same link.
ULA
Unique Local Address
Defined in RFC 4193. Via this address, the IPv6 interface can be reached in the LAN.
GUA
Global Unicast Address Via this address, the IPv6 interface can be reached, e.g. via the
Internet.
Interface ID
The interface ID is formed with the EUI-64 method or manually.
EUI-64
Extended Unique Identifier (RFC 4291); method for forming the interface ID. In Ethernet, the
interface ID is formed from the MAC address of the interface. Divides the MAC address into
the manufacturer-specific part (OUI) and the network-specific part (NIC) and inserts FFFE
between the two parts.
Example:
MAC address = AA:BB:CC:DD:EE:FF
OUI = AA:BB:CC
NIC = DD:EE:FF
EUI-64 = OUI + FFFE + NIC = AA:BB:CC:FF:FE:DD:EE:FF
Scope
Defines the range of the IPv6 address.

IP addresses
3.3 IPv6 addresses
3.3.2Structure 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
Structure of the IPv6 address
The IPv6 protocol distinguishes three types of address: Unicast , anycast and multicast. The
following section describes the structure of the global unicast addresses.
IPv6 prefixSuffix
Global prefix:
