Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
http://www.siemens.com/industrialsecurity (http://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

Product characteristics
The IE switches have the following properties:
●The Ethernet interfaces support the following modes:
–10 Mbps and 100 Mbps both in full and half duplex
–1000 Mbps full duplex (XC206-2SFP with the appropriate pluggable transceivers and
SCALANCE XP216)
–Autonegotiation
–Autocrossing
–Autopolarity
●EtherNet/IP
EtherNet/IP (Ethernet/Industrial Protocol) is an open industry standard for industrial real-
time Ethernet based on TCP/IP and UDP/IP.
●PROFINET
PROFINET (Process Field Network) is an open industry standard for industrial real-time
Ethernet based on TCP/IP and IT standards. Via PROFINET distributed IO devices can
be connected to a controller.
●Redundancy method Spanning Tree Protocol.
The redundancy mechanism Spanning Tree defines several connection paths between
nodes in a network, only one of which is ever active. This suppresses loops and
optimizes the paths.

●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.
●Load limitation when using multicast and broadcast protocols, for example video
transmission
By learning the multicast sources and destinations (IGMP snooping, IGMP querier), IE
switches can filter multicast data traffic and so reduce the load in the network. Multicast
and broadcast data traffic can be limited.
●Time-of-day synchronization
Diagnostics messages such as 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 server and therefore makes the identification of diagnostics
messages of several devices easier.
●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)
●Port mirroring
Mirroring allows the data traffic of a port to be mirrored at another port (monitor port). The
data traffic can then be analyzed at this monitor port without any effects on the data
traffic.
●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 made via a RADIUS server that must be reachable over the
network.
●Log table
The log table logs events that occur during operation. The user can specify which events
cause an entry in the table.
●Link aggregation (IEEE 802.1AX) for bundling ports (SCALANCE XC-200/SCALANCE
XP-200)

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.

SCALANCE XB-200/XC-200/XP-200 Web Based Management
16 Configuration Manual, 07/2016, C79000-G8976-C360-04
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
Initial assignment of an IP 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
(factory setting)
●
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 IE switch via Ethernet.
–You will find the PST on the Internet pages of Siemens Industry Online Support under
the entry ID 19440762
(http://support.automation.siemens.com/WW/view/en/19440762).
–For further information about assigning the IP address with the PST, refer to the
documentation "Primary Setup Tool (PST)".
●
STEP 7
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.

"Creating a PROFINET IO system".
Note
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.
3.3
Address 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.
●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.
●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 and server. The
address can be assigned via the MAC address, the DHCP client ID, the PROFINET or
the system name. You configure the parameter in "System > DHCP > DHCP Client".

PROFINET
PROFINET
PROFINET is an open standard (IEC 61158/61784) for industrial automation based on
Industrial Ethernet. PROFINET uses existing IT standards and allows end-to-end
communication from the field level to the management level as well as plant-wide
engineering. PROFINET also has the following features:
●Use of TCP/IP
●Automation of applications with real-time requirements
–Real-Time (RT) communication
–Isochronous Real-Time (IRT) communication
●Seamless integration of fieldbus systems
You configure PROFINET in "System > PROFINET (Page 153)".
PROFINET IO
Within the framework of PROFINET, PROFINET IO is a communications concept for
implementing modular, distributed applications. PROFINET IO is implemented by the
PROFINET standard for programmable controllers (IEC 61158-x-10).
