Ethernet based on TCP/IP and IT standards. Via PROFINET IO (Input/Output) 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.

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.

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 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.
– STEP 7 as of V5.5.4 HF9
For further information on the assignment of the IP address using STEP 7 refer to the
documentation "Configuring Hardware and Communication Connections STEP 7", in
the section "Steps For Configuring a PROFINET IO System".

3.3 Address assignment with DHCP
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.
Once this period has elapsed, the client must either request a new IP address or extend
the lease time of the existing IP address.
● 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, the PROFINET or the system name.
You configure the parameter in "System > DHCP > DHCP Client".
● The following DHCP options are supported:
– DHCP option 66: Assignment of a dynamic TFTP server name
– DHCP option 67: Assignment of a dynamic boot file name
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.

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 > PNIO (Page 150)".
PROFINET IO
Within the framework of PROFINET, PROFINET IO is a communications concept for

EtherNet/IP
EtherNet/IP (Ethernet/Industrial Protocol) is an open industry standard for industrial real-time
Ethernet based on TCP/IP and UDP/IP. With EtherNet/IP, Ethernet is expanded by the
Common Industrial Protocol (CIP) at the application layer. In EtherNet/IP, the lower layers of
the OSI reference model are adopted by Ethernet with the physical, network and transport
functions.
You configure EtherNet/IP in "System > EtherNet/IP (Page 152)".
Common Industrial Protocol
The Common Industrial Protocol (CIP) is an application protocol for automation that supports
transition of the field buses in Industrial Ethernet and in IP networks. This industry protocol is
used by field buses/industrial networks such as DeviceNet, ControlNet and EtherNet/IP at
the application layer as an interface between the deterministic fieldbus world and the
automation application (controller, I/O, HMI, OPC, ...). The CIP is located above the transport
layer and expands the pure transport services with communications services for automation
engineering. These include services for cyclic, time-critical and event-controlled data traffic.
CIP distinguishes between time-critical I/O messages (implicit messages) and individual
query/response frames for configuration and data acquisition (explicit messages). CIP is
object-oriented; all data "visible" from the outside is accessible in the form of objects. CIP
has a common configuration basis: EDS (Electronic Data Sheet).
Electronic Data Sheet
Electronic Data Sheets (EDS) are electronic datasheets for describing devices.
The EDS required for EtherNet/IP operation can be found in "System > Load&Save
(Page 92)".

Redundancy mechanism
4.4.1
Spanning Tree
Avoiding loops on redundant connections
The spanning tree algorithm allows network structures to be created in which there are
several connections between two stations. Spanning tree prevents loops being formed in the
network by allowing only one path and disabling the other (redundant) ports for data traffic. If
there is an interruption, the data can be sent over an alternative path. The functionality of the
spanning tree algorithm is based on the exchange of configuration and topology change
frames.
Definition of the network topology using the configuration frames
The devices exchange configuration frames known as BPDUs (Bridge Protocol Data Units)
with each other to calculate the topology. The root bridge is selected and the network
topology created using these frames. BPDUs also bring about the status change of the root
ports.
The root bridge is the bridge that controls the spanning tree algorithm for all involved
components.
Once the root bridge has been specified, each device sets a root port. The root port is the
port with the lowest path costs to the root bridge.
Response to changes in the network topology
If nodes are added to a network or drop out of the network, this can affect the optimum path
selection for data packets. To be able to respond to such changes, the root bridge sends
configuration messages at regular intervals. The interval between two configuration
messages can be set with the "Hello Time" parameter.
Keeping configuration information up to date
With the "Max Age" parameter, you set the maximum age of configuration information. If a
bridge has information that is older than the time set in "Max Age", it discards the message
and initiates recalculation of the paths.
New configuration data is not used immediately by a bridge but only after the period
specified in the "Forward Delay" parameter. This ensures that operation is only started with
the new topology after all the bridges have the required information.

4.4 Redundancy mechanism
4.4.1.1
RSTP, MSTP, CIST
Rapid Spanning Tree Protocol (RSTP)
One disadvantage of STP is that if there is a disruption or a device fails, the network needs
to reconfigure itself: The devices start to negotiate new paths only when the interruption
occurs. This can take up to 30 seconds. Fur this reason, STP was expanded to create the
"Rapid Spanning Tree Protocol" (RSTP, IEEE 802.1w). This 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
means that the reconfiguration time for an RSTP controlled network can be reduced to a few
seconds.
This is achieved by using the following functions:
● Edge ports (end node port)
Edge ports are ports connected to an end device.
A port that is defined as an edge port is activated immediately after connection
establishment. If a spanning tree BPDU is received at an edge port, the port loses its role
as edge port and it takes part in (R)STP 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.
● Alternate 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
Rapid spanning tree reacts to events, for example an aborted connection, without delay.
There is no waiting for timers as in spanning tree.
● Counter for the maximum 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)
The Multiple Spanning Tree Protocol (MSTP) is a further development of the Rapid
Spanning Tree Protocol. Among other things, it provides the option of operating several
RSTP instances within different VLANs or VLAN groups and, for example, making paths
available within the individual VLANs that the single Rapid Spanning Tree Protocol would
globally block.
Common and Internal Spanning Tree (CIST)
CIST identifies the internal instance used by the switch that is comparable in principle with
an internal RSTP instance.

4.4 Redundancy mechanism
4.4.2
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 (RM). 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 the 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 RM no longer arrive at the other ring port due to an interruption, the
RM switches through its two ring ports and informs the redundancy clients of the change
immediately. The reconfiguration time after an interruption of the ring is a maximum of 0.3
seconds.
Standby redundancy
Standby redundancy is a method with which rings each of which is protected by high-speed
redundancy 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.
In topologies with SCALANCE X-200 and SCALANCE X-300 IE switches, up to 100
nodes are supported.
Exceeding this number of devices can lead to a loss of data traffic.
● The ring in which you want to use HRP may only consist of 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 IE switches are possible. At
greater distances, the specified reconfiguration time may be longer.
● A device in the ring must be configured as redundancy manager by selecting the "HRP
Manager" setting. This configuration can be set in Web Based Management, Command
Line Interface or using SNMP. On all other devices in the ring, either the "HRP Client" or
"Automatic Redundancy Detection" mode must be activated. This can be achieved in
Web Based Management, Command Line Interface or using SNMP.
● In the basic status, the "HRP Client" or "Automatic Redundancy Detection" mode is set as
default.

MRP - Media Redundancy Protocol
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 "Configuration in STEP 7
(Page 30)").
● 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.

Role
The choice of role depends on the following use cases:
● You want to use MRP in a ring topology only with Siemens devices:
– For at least one device in the ring select "Automatic Redundancy Detection" or "MRP
Auto Manager".
– For all other devices in the ring select "MRP Client" or "Automatic Redundancy
Detection".
● You want to use MRP in a ring topology that also includes non-Siemens devices:
– For exactly one device in the ring select the role "MRP Auto Manager".
– For all other devices in the ring topology, select the role of "MRP Client".
Note
The use of "Automatic Redundancy Detection" is not possible when using non-Siemens
devices.
● You configure the devices in an MRP ring topology partly with WBM and partly with STEP
7:
– With the devices you configure using WBM, select "MRP Client" for all devices.
– With the devices that you configure using STEP 7, select precisely one device as
"Manager" or "Manager (Auto)" and "MRP Client" for all other devices.
Note
If a device is assigned the role of "Manager" with STEP 7, all other devices in the ring
must be assigned the "MRP Client" role. If there is a device with the "Manager" role and a
device with the "Manager (Auto)"/"MRP Auto-Manager" in a ring, this can lead to
circulating frames and therefore to failure of the network.

These settings are described below.
Note
Valid MRP configuration
In the MRP configuration in STEP 7, make sure that all devices in the ring have a valid MRP
configuration before you close the ring. Otherwise, there may be circulating frames that will

The MRP settings remain in effect following a restart of the device or following a power down
and hot restart.
Note
Prioritized startup
If you configure MRP in a ring, you cannot use the "prioritized startup" function in PROFINET
applications on the devices involved.
If you want to use the "prioritized startup" function, then disable MRP in the configuration.
In the STEP 7 configuration, set the role of the relevant device to "Not a node in the ring".

Domain
Single MRP rings
If you want to configure a single MRP ring, leave the factory setting "mrpdomain 1" in the
"Domain" drop-down list.
All devices configured in a ring with MRP must belong to the same redundancy domain. A
device cannot belong to more than one redundancy domain.
If you leave the setting for "Domain" as the factory set "mrpdomain-1", the defaults for "Role"
and "Ring ports" also remain active.
MRP multiple rings
If you configure multiple MRP rings, the nodes of the ring will be assigned to the individual
rings with the "Domain" parameter.
Set the same domain for all devices within a ring. Set different domains for different rings.
Devices that do not belong to the same ring must have different domains.
Role
The choice of role depends on the following use cases.
● You want to use MRP in a topology with one ring only with Siemens devices and without
monitoring diagnostic interrupts:
Assign all devices to the "mrpdomain-1" domain and the role "Manager (Auto)".
The device that actually takes over the role of redundancy manager, is negotiated by
Siemens devices automatically.
● You want to use MRP in a topology with multiple rings only with Siemens devices and
without monitoring diagnostic interrupts (MRP multiple rings):
– Assign the device that connects the rings the role of "Manager".
– For all other devices in the ring topology, select the role of "Client".
● You want to use MRP in a ring topology that also includes non-Siemens devices or you
want to receive diagnostic interrupts relating to the MRP status from a device (see
"Diagnostic interrupts"):
– Assign precisely one device in the ring the role of "Manager (Auto)".

4.4 Redundancy mechanism
● You want to disable MRP:
Select the option "Not node in the ring" if you do not want to operate the device within a
ring topology with MRP.
Note
Role after resetting to factory settings
With brand new Siemens devices and those reset to the factory settings the following
MRP role is set:
• CPs:
"Manager (Auto)"
• SCALANCE X-200, SCALANCE XB-200/SCALANCE XP-200 (PROFINET variants),
SCALANCE X-300 and SCALANCE X-400:
"Automatic Redundancy Detection"
If you are operating a non-Siemens device as the redundancy manager in the ring, this
may cause loss of the data traffic.
With brand new SCALANCE XB-200/SCALANCE XP-200 (EtherNet/IP variants),
SCALANCE XM-400 and SCALANCE XR-500 IE switches and those set to the factory
settings, MRP is disabled and spanning tree enabled.
Ring port 1 / ring port 2
Here, select the port you want to configure as ring port 1 and ring port 2.
With devices with more than 8 ports, not all ports can be selected as ring port.
The drop-down list shows the selection of possible ports for each device type. If the ports are
specified in the factory, the boxes are grayed out.
NOTICE
Ring ports after resetting to factory settings
If you reset to the factory settings, the ring port settings are also reset.
If other ports were used previously as ring ports before resetting, with the appropriate
attachment, a previously correctly configured device can cause circulating frames and
therefore the failure of the data traffic.
Diagnostic interrupts
Enable the "Diagnostic interrupts" option, if you want diagnostic interrupts relating to the
MRP status on the local CPU to be output.

4.4 Redundancy mechanism
The following diagnostic interrupts can be generated:
● Wiring or port error
Diagnostic interrupts are generated if the following errors occur at the ring ports:
– Connection abort on a ring port
– A neighbor of the ring port does not support MRP.
– A ring port is connected to a non-ring port.
– A ring port is connected to the ring port of another MRP domain.
● Status change active/passive (redundancy manager only)
If the status changes (active/passive) in a ring, a diagnostics interrupt is generated.
Parameter assignment of the redundancy is not set by STEP 7 (redundancy alternatives)
This option only affects SCALANCE X switches. Select this option if you want to set the
properties for media redundancy using alternative mechanisms such as WBM, CLI or SNMP.
If you enable this option, existing redundancy settings from WBM, CLI or SNMP, are retained
and are not overwritten. The parameters in the "MRP configuration" box are then reset and
grayed out. The entries then have no meaning.
4.4.4
Standby
General
SCALANCE X switches support not only ring redundancy within a ring but also redundant
linking of rings or open network segments (linear bus). In the redundant link, rings are
connected together over 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
Image 4-2
Example of a redundant link between rings
For a redundant link as shown in the figure, two devices must be configured as standby
redundancy switches within a network segment. In this case, network segments are rings
with a redundancy manager. Instead of rings, network segments might also be linear.
The two standby redundancy switches 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.

Parallel Redundancy Protocol
Parallel Redundancy Protocol
The "Parallel Redundancy Protocol" (PRP) is a redundancy protocol for Ethernet networks. It
is defined in Part 3 of the IEC 62439 standard. This redundancy method allows data
communication to be maintained without interruption/reconfiguration time if there are
interruptions in the network.
The PRP method is supported, for example, by the devices of the SCALANCE X-200RNA
product line.
Overlong frames
When sending PRP frames, the IE switch expands the frame with a PRP trailer. With frames
with the maximum length, appending the PRP trailer results in an overlong frame that
exceeds the maximum permitted frame length (according to the IEEE 802.3 standard).
To prevent data loss with overlong frames, all network components located in a PRP
network must support a frame length of at least 1528 bytes.
The devices described in this manual can be used in PRP networks, see also section
"Configuration limits (Page 21)".

VLAN
Network definition regardless of the spatial location of the nodes
VLAN (Virtual Local Area Network) divides a physical network into several logical networks
that are shielded from each other. Here, devices are grouped together to form logical groups.
Only nodes of the same VLAN can address each other. Since multicast and broadcast
frames are only forwarded within the particular VLAN, they are also known as broadcast
domains.
The particular advantage of VLANs is the reduced network load for the nodes and network
segments of other VLANs.
To identify which packet belongs to which VLAN, the frame is expanded by 4 bytes (VLAN
tagging (Page 37)). This expansion includes not only the VLAN ID but also priority
information.
Options for the VLAN assignment
Each port of a device is assigned a VLAN ID (port-based VLAN). You configure port-based
VLAN in "Layer 2 > VLAN > Port-based VLAN (Page 181)".

VLAN tagging
Expansion of the Ethernet frames by four bytes
For CoS (Class of Service, frame priority) and VLAN (virtual network), the IEEE 802.1Q
standard defined the expansion of Ethernet frames by adding the VLAN tag.
Note
The VLAN tag increases the permitted total length of the frame from 1518 to 1522 bytes.
The end nodes on the networks must be checked to find out whether they can process this
length / this frame type. If this is not the case, only frames of the standard length may be
sent to these nodes.
The additional 4 bytes are located in the header of the Ethernet frame between the source
address and the Ethernet type / length field:
Image 4-3
Structure of the expanded Ethernet frame
The additional bytes contain the tag protocol identifier (TPID) and the tag control information
(TCI).
Tag protocol identifier (TPID)
The first 2 bytes form the Tag Protocol Identifier (TPID) and always have the value 0x8100.
This value specifies that the data packet contains VLAN information or priority information.
Tag Control Information (TCI)
The 2 bytes of the Tag Control Information (TCI) contain the following information:

Technical basics
4.6 VLAN tagging
The tagged frame has 3 bits for the priority that is also known as Class of Service (CoS). The
priority according to IEEE 802.1P is as follows:
CoS bits
000
Type of data
Non time-critical data traffic (less then best effort [basic setting])
001
Normal data traffic (best effort [background])
010
Reserved (standard)
011
Reserved ( excellent effort )
100
Data transfer with max. 100 ms delay
101
Guaranteed service, interactive multimedia
110
Guaranteed service, interactive voice transmission
111
Reserved
The prioritization of the data packets is possible only if there is a queue in the components in
which they can buffer data packets with lower priority.
The device has multiple parallel queues in which the frames with different priorities can be
processed. First, the frames with the highest priority ("Strict Priority" method) are processed.
This method ensures that the frames with the highest priority are sent even if there is heavy
data traffic.
Canonical Format Identifier (CFI)
The CFI is required for compatibility between Ethernet and the token Ring.
The values have the following meaning:
Value
Meaning
0
The format of the MAC address is canonical. In the canonical representation of the MAC
address, the least significant bit is transferred first. Standard-setting for Ethernet switches.
1
The format of the MAC address is not canonical.
VLAN ID
In the 12-bit data field, up to 4096 VLAN IDs can be formed. The following conventions
apply:
VLAN ID
Meaning
0
The frame contains only priority information (priority tagged frames) and no valid
VLAN identifier.
1- 4094
Valid VLAN identifier, the frame is assigned to a VLAN and can also include priority information.

4.7 SNMP
4.7
SNMP
Introduction
With the aid of the Simple Network Management Protocol (SNMP), you monitor and control
network components from a central station, for example routers or switches. SNMP controls
the communication between the monitored devices and the monitoring station.
Tasks of SNMP:
● Monitoring of network components
● Remote control and remote parameter assignment of network components
● Error detection and error notification
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. Define different community strings for read and
write permissions. The community strings are transferred in plain text.
Standard values of the community strings:
● public
has only read permissions
● private
has read and write permissions
Note
Because the SNMP community strings are used for access protection, do not use the
standard values "public" or "private". Change these values following the initial
commissioning.
Further simple protection mechanisms at the device level:
● Allowed Host
The IP addresses of the monitoring systems are known to the monitored system.
● Read Only
If you assign "Read Only" to a monitored device, monitoring stations can only read out
data but cannot modify it.
SNMP data packets are not encrypted and can easily be read by others.
The central station is also known as the management station. An SNMP agent is installed on
the devices to be monitored with which the management station exchanges data.

4.7 SNMP
The management station sends data packets of the following type:
● GET
Request for a data record from the SNMP agent
● GETNEXT
Calls up the next data record.
● GETBULK (available as of SNMPv2c)
Requests multiple data records at one time, for example several rows of a table.
● SET
Contains parameter assignment data for the relevant device.
The SNMP agent sends data packets of the following type:
● RESPONSE
The SNMP agent returns the data requested by the manager.
● TRAP
If a certain event occurs, the SNMP agent itself sends traps.
SNMPv1/v2c/v3 use UDP (User Datagram Protocol) and use the UDP ports 161 and 162.
The data is described in a Management Information Base (MIB).
SNMPv3
Compared with the previous versions SNMPv1 and SNMPv2c, SNMPv3 introduces an
extensive security concept.
SNMPv3 supports:
● Fully encrypted user authentication
● Encryption of the entire data traffic
● Access control of the MIB objects at the user/group level

4.8 Quality of service
4.8
Quality of service
Quality of Service (QoS) is a method to allow efficient use of the existing bandwidth in a
network.
QoS is implemented by prioritization of the data traffic. Incoming frames are sorted into a
Queue according to a certain prioritization and further processed. This gives certain frames
priority.
The different QoS methods influence each other and are therefore taken into account in the
following order:
1. The switch first checks whether the incoming frame is a broadcast or agent frame.
→ When the first condition is met, the switch takes into account the priority set on the
"General (Page 166)" page.
The switch sorts the frame into a queue according to the assignment on page "CoS Map
(Page 168)".
2. If the first condition is not met the switch checks whether the frame contains a VLAN tag.
→ If the second condition is met the switch checks the settings for the priority on the
"General (Page 166)" page. The switch checks whether a value other than "Do not force"
is set for the priority.
If the priority is set the switch sorts the frame into a queue according to the assignment
on page "CoS Map (Page 168)".
3. If the second condition is also not met the frames are further processed according to the
Trust mode. You configure the Trust mode on the page "QoS Trust (Page 170)".

Web Based Management
How it works
The device has an integrated HTTP server for Web Based Management (WBM). If a device
is addressed using an Internet browser, it returns HTML pages to the client PC depending on
the user input.
The user enters the configuration data in the HTML pages sent by the device. The device
evaluates this information and generates reply pages dynamically.
The advantage of this method is that only an Internet browser is required on the client.
Note
Secure connection
WBM also allows you to establish a secure connection via HTTPS.
Use HTTPS for protected transfer of your data. If you wish to access WBM only via a secure
connection, activate the option "HTTPS Server only" under "System > Configuration".
Requirements
WBM display
● The device has an IP address
● There is a connection between the device and the client PC. With the ping command, you
can check whether or not a device can be reached.
● Access using HTTPS is enabled.
● JavaScript is activated in the Internet browser.
● The Internet browser must not be set so that it reloads the page from the server each
time the page is accessed. The updating of the dynamic content of the page is ensured
by other mechanisms. In the Internet Explorer, you can make the appropriate setting in
the "Options > Internet Options > General" menu in the section "Browsing history" with
the "Settings" button. Under "Check for newer versions of stored pages:", select
"Automatically".
● If a firewall is used, the relevant ports must be opened.
– For access using HTTP: TCP port 80
– For access using HTTPS: TCP port 443

address has the lowest numeric value will become the root bridge. Both parameters,
bridge priority and MAC address together form the bridge identifier. Since the root bridge
manages all path changes, it should be located as centrally as possible due to the delay
of the frames. The value for the bridge priority is a whole multiple of 4096 with a range of
values from 0 to 32768.
● Bridge address / Root address
The bridge address shows the MAC address of the device and the root address shows
the MAC address of the root switch.
● Root Cost
Shows the path costs from the device to the root bridge.
● Bridge Status
Shows the status of the bridge, e.g. whether or not the device is the root bridge.
● Regional root priority (available only with MSTP)

Shows the MAC address of the device.
● Regional Root Cost (available only with MSTP)
Shows the path costs from the regional root bridge to the root bridge.
The table has the following columns:
● Port
Shows the port via which the device communicates. The port is made up of the module
number and the port number, for example port 0.1 is module 0, port 1.
● Role
Shows the status of the port. The following values are possible:
– Disabled
The port was removed manually from the spanning tree and will no longer be taken
into account by the spanning tree.

● Status
Displays the current status of the port. The values are only displayed. The parameter
depends on the configured protocol. The following statuses are possible:
– Discarding
The port receives BPDU frames. Other incoming or outgoing frames are discarded.
– Listening
The port receives and sends BPDU frames. The port is involved in the spanning tree
algorithm. Other outgoing and incoming frames are discarded.
– Learning
The port actively learns the topology; in other words, the node addresses. Other
outgoing and incoming frames are discarded.
– Forwarding
Following the reconfiguration time, the port is active in the network. The port receives
and sends data frames.
● Oper. Version
Shows the compatibility mode of Spanning Tree used by the port.
● Priority
If the path calculated by the spanning tree is possible over several ports of a device, the
port with the highest priority (in other words the lowest value for this parameter) is
selected. A value between 0 and 240 can be entered for the priority in steps of 16. If you
enter a value that cannot be divided by 16, the value is automatically adapted. The
default is 128.
● Path Cost
This parameter is used to calculate the path that will be selected. The path with the
lowest value is selected. If several ports of a device have the same value, the port with
the lowest port number is selected.
If the value in the "Cost Calc." box is "0", the automatically calculated value is displayed.
Otherwise, the value of the "Cost Calc. box" is displayed.
The calculation of the path costs is largely based on the transmission speed. The higher
the achievable transmission speed is, the lower the value of the path costs.
Typical values for path costs with rapid spanning tree:
– 10,000 Mbps = 2,000
– 1000 Mbps = 20,000
– 100 Mbps = 200,000
– 10 Mbps = 2,000,000
You configure the "Cost. Calc." on the pages "Layer 2 > Spanning Tree > CIST Port" and
"Layer 2 > Spanning Tree > MST Port".

Note
Device with the higher MAC address becomes master
When linking HRP rings redundantly, two devices are always configured as a master/slave
pair. This also applies to interrupted HRP rings = linear buses. When operating normally, the
device with the higher MAC address adopts the role of master.
This type of assignment is important in particular when a device is replaced. Depending on
the MAC addresses, the previous device with the slave function can take over the role of the
standby master.

modifications must be saved manually before a restart. In "Automatic Save" mode, the
last changes are saved automatically before a restart.
Reset to Factory Defaults
By resetting all the settings to the factory settings, the IP address and the passwords are
also lost. Following this, the device can only be accessed via the serial interface, using the
Primary Setup Tool or using DHCP.
NOTICE
With the appropriate attachment, a previously correctly configured device can cause
circulating frames and therefore the failure of the data traffic.
Resetting to defaults (profiles)
The profiles provide a preconfiguration for various use cases of the devices.
When you start a device with the default settings of a profile, the settings are reset to the
factory settings and some parameters are set so that they are designed for a use case. In
contrast to resetting to the factory defaults. the users and passwords are retained after the
restart. The configured IP address is lost so that device can then only be accessed via the
serial interface, using the Primary Setup Tool or using DHCP.
NOTICE
With the appropriate attachment, a previously correctly configured device can cause
circulating frames and therefore the failure of the data traffic.
Which settings were set specially for the profile are displayed before the restart.
The profiles can be used independently of the factory setting of the device.

the device starts up with the factory settings after the firmware has been installed.
In this situation, if a PLUG is inserted in the device, following the restart, this has the status
"Not Accepted" since the PLUG still has the configuration data of the previous more up-todate firmware. This allows you to return to the previous, more up-to-date firmware without
any loss of configuration data. If the original configuration on the PLUG is no longer required,
the PLUG can be deleted or rewritten manually using the WBM page "System > PLUG".

the device starts up with the factory settings after the firmware has been installed.
In this situation, if a PLUG is inserted in the device, following the restart, this has the status
"Not Accepted" since the PLUG still has the configuration data of the previous more up-todate firmware. This allows you to return to the previous, more up-to-date firmware without
any loss of configuration data. If the original configuration on the PLUG is no longer required,
the PLUG can be deleted or rewritten manually using the WBM page "System > PLUG".

Relay Agent Information
On this page you define that devices with a certain remote ID and circuit ID are assigned the
IPv4 addresses from a specific address band.
If you create such an entry for an address band, the ports of the address band only react to
DHCP queries via a DHCP relay agent (option 82). You can create further address bands for
the same VLAN IP interfaces so that ports react to different requests.
Note
Extension or release of an IPv4 address assigned via a relay agent.
With address assignments via a relay agent "Renew" and "Release" messages going directly
from the DHCP client to the DHCP server are ignored by the server.
• The extension of the period for an IPv4 address assigned via a relay agent is achieved
using a "Rebinding" message that the client sends automatically as a broadcast.
• To speed up the release of an IPv4 address assigned via a relay agent, configure a
shorter period of validity.

Configure whether or not the power supply should be monitored by the messaging system.
Depending on the hardware variant, there are one or two power connectors (Supply 1 /
Supply 2). With a redundant power supply, configure the monitoring separately for each
individual feed-in line.
A fault is then signaled by the message system when there is no power on a monitored
connection (Line 1 or Line 2) or when the applied voltage is too low.
Note
You will find the permitted operating voltage limits in the operating instructions of the device.
A fault causes the signaling contact to trigger and the fault LED on the device to light up and,
depending on the configuration, can trigger a trap, an e-mail, or an entry in the event log
table.

Cable Tester
With this page, each individual Ethernet port can run independent fault diagnostics on the
cable. This test is performed without needing to remove the cable, connect a cable tester
and install a loopback module at the other end. Short-circuits and cable breaks can be
localized to within a few meters.
Note
Please note that this test is permitted only when no data connection is established on the
port to be tested.
If, however, there is a data connection to the port to be tested, this is briefly interrupted.
Automatic re-establishment of the connection can fail and then needs to be done manually.
Description
The page contains the following boxes:
● Port
Select the required port from the drop-down list.

If you select "Ring" in the "Redundancy Type" drop-down list, the following options are
then available:
– Automatic Redundancy Detection
Select this setting to create an automatic configuration of the redundancy mode.
In the "Automatic Redundancy Detection" mode, the device automatically detects
whether or not there is a device with the "HRP Manager" role in the ring. If there is, the
device adopts the role "HRP" client.
If no HRP manager is found, all devices with the "Automatic Redundancy Detection"
or "MRP Auto Manager" setting negotiate among themselves to establish which
device adopts the role of "MRP Manager". The device with the lowest MAC address
will always become "MRP Manager". The other devices automatically set themselves
to "MRP Client" mode.
– MRP Auto-Manager
In the "MRP Auto Manager" mode, the devices negotiate among themselves to
establish which device will adopt the role of "MRP Manager". The device with the
lowest MAC address will always become "MRP Manager". The other devices
automatically set themselves to "MRP Client" mode.
In contrast to the setting "Automatic Redundancy Detection", the devices are not
capable of detecting whether or not an HRP manager is in the ring.
Note
MRP configuration in STEP 7
If you set the role "Manager (Auto)" or "Manager" for the device in STEP 7, in both
cases, "MRP Auto Manager" is displayed on this WBM page. In the display in the CLI,
a distinction is made between the two roles.
– MRP Client
The device adopts the role of MRP client.
– HRP Client
The device adopts the role of HRP client.
– HRP Manager
Te device adopts the role of HRP manager.
When you configure an HRP ring, one device must be set as HRP manager. For all
other devices, "HRP Client" or "Automatic Redundancy Detection" must be set.
If you select "Spanning Tree" in the "Redundancy Type" drop-down list, the following

With passive listening, you can connect spanning tree networks to MRP/HRP rings. The
ring nodes forward spanning tree BPDUs and therefore react to topology changes. When
a topology change frame is received, the MAC address table is deleted.
● RMON
If you select this check box, Remote Monitoring (RMON) allows diagnostics data to be
collected on the device, prepared and read out using SNMP by a network management
station that also supports RMON. This diagnostic data, for example port-related load
trends, allow problems in the network to be detected early and eliminated. Some of the
"Ethernet statistics counters" are part of the RMON function. If you disable RMON, the
"Ethernet statistics counter" in "Information > Ethernet statistics" is no longer updated.

Make sure you keep to the following rules when configuring and operating your VLANs:
● Frames with the VLAN ID "0" are handled as untagged frames but retain their priority
value.
● As default, all ports on the device send frames without a VLAN tag to ensure that the end
node can receive these frames.
● With SCALANCE X devices, the VLAN ID "1" is the default on all ports.
● If an end node is connected to a port, outgoing frames should be sent without a tag (static
access port). If, however, there is a further switch at this port, the frame should have a
tag added (trunk port).

Shows the available ports. The port is made up of the module number and the port
number, for example port 0.1 is module 0, port 1.
● Priority
From the drop-down list, select the priority given to untagged frames.
The CoS priority (Class of Service) used in the VLAN tag. If a frame is received without a
tag, it will be assigned this priority. This priority specifies how the frame is further
processed compared with other frames.
There are a total of eight priorities with values 0 to 7, where 7 represents the highest
priority (IEEE 802.1p Port Priority).
● Port VID
Select the VLAN ID from the drop-down list. Only VLAN IDs defined on the "VLAN >
General" page can be selected.
If a received frame does not have a VLAN tag, it has a tag with the VLAN ID specified
here added to it and is sent according to the rules at the port.
● Acceptable Frames
Specify which types of frames will be accepted. The following alternatives are possible:
– Tagged Frames Only
The device discards all untagged frames. Otherwise, the forwarding rules apply
according to the configuration.
– All
The device forwards all frames.
● Ingress Filtering
Specify whether the VID of received frames is evaluated
You have the following options:
– Enabled
The VLAN ID of received frames decides whether they are forwarded: To forward a
VLAN tagged frame, the receiving port must be a member in the same VLAN. Frames
from unknown VLANs are discarded at the receiving port.
– Disabled
All frames are forwarded.

Mirroring
Note
It cannot be guaranteed when mirroring the data traffic that all packets are mirrored.
Mirroring
The device provides the option of simultaneously channeling incoming or outgoing data
streams via other interfaces for analysis or monitoring. This has no effect on the monitored
data streams. This procedure is known as mirroring. In this menu section, you enable or
disable mirroring and set the parameters.
Mirroring ports
Mirroring a port means that the data traffic at a port (mirrored port) of the IE switch is copied
to another port (monitor port). You can mirror one or more ports to a monitor port.
If a protocol analyzer is connected to the monitor port, the data traffic at the mirrored port
can be recorded without interrupting the connection. This means that the data traffic can be
investigated without being affected. This is possible only if a free port is available on the
device as the monitor port.
5.5.5.1
General
Mirroring in general
On this page, you can enable or disable the mirroring function and make the basic settings.
Note
You need to disable port mirroring if you want to connect a normal end device to the monitor
port.
Note the data rate
If the maximum data rate of the mirrored port is higher than that of the monitor port, data
may be lost and the monitor port no longer reflects the data traffic at the mirrored port.
Several ports can be mirrored to one monitor port at the same time.
Several source ports from the same VLAN
If in a VLAN you select more than one source port for the port-based egress mirroring,
unknown unicast and multicast frames as well as broadcast frames are forwarded only once
to the destination port.

• DCP forwarding is turned off
• LLDP is turned off
• Unicast, multicast and broadcast blocking is turned on
The previous statuses of these functions are no longer restored after disabling monitor
barrier again. They are reset to the default values and may need to be reconfigured.
You can configure these functions manually even if monitor barrier is turned on. The data
traffic on the monitor port is, however, also allowed again. If you do not require this, make
sure that only the data traffic you want to monitor is forwarded to the interface.
If mirroring is disabled, the listed port-specific functions are reset to the default values.
This reset takes place regardless of whether the functions were configured manually or
automatically by enabling monitor barrier.

Dynamic MAC Aging
Protocol settings and switch functionality
The device automatically learns the source addresses of the connected nodes. This
information is used to forward data frames to the nodes specifically involved. This reduces
the network load for the other nodes.
If a device does not receive a frame whose source address matches a learnt address within
a certain time, it deletes the learnt address. This mechanism is known as "Aging". Aging
prevents frames being forwarded incorrectly, for example when an end device (for example a
programming device) is connected to a different switch port.
If the check box is not enabled, a device does not delete learnt addresses automatically.

Standby
Redundant linking of rings
Standby redundancy allows the redundant linking of HRP rings.
To establish a standby connection, configure two neighboring devices within a ring as
standby master or standby slave. The standby master and the standby slave must be
connected via parallel cables to two devices in another ring.
In problem-free operation, messages are exchanged between the two rings via the master. If
the master's line is disturbed, the slave takes over the forwarding of messages between the
two rings.
Enable standby redundancy for both standby partners and select the ports via which the
device is connected to the rings you want to link to.
For the "Standby Connection Name", a name unique within the ring must be assigned for
both partners. This identifies the two modules that belong together as standby partners.
Note
To be able to use the function, HRP must be activated.
The standby manager always requires an activated HRP client.

is enabled, then assuming that no error has occurred, the device with the higher MAC
address adopts the role of standby master.
– If the option is selected for both devices or if the "Force device to Standby Master"
property is supported by only one device, the standby master is also selected based
on the MAC address.
This type of assignment is important in particular when a device is replaced. Depending
on the MAC addresses, the previous device with the slave function can take over the role
of the standby master.
Note
If two devices are linked by the standby function, the "Standby" function must be enabled
on both devices.
● Standby Port
Select the port to be standby port. The link to the other ring is via the standby port.
The standby port is involved in the redirection of data traffic. In there are no problems,
only the standby port of the master is enabled and handles the data traffic into the
connected HRP ring or HRP bus.
If the master or the Ethernet connection (link) of one of the standby port of the master
fails, the standby port of the master will be disabled and the standby port of the slave
enabled. As a result, a functioning Ethernet connection to the connected network
segment (HRP ring or HRP linear bus) is restored.

The Bridge Priority decides which device becomes the Root Bridge. The Bridge with the
highest priority becomes the Root Bridge. The lower the value, the higher the priority. If
several devices in a network have the same priority, the device whose MAC address has
the lowest numeric value will become the root bridge. Both parameters, bridge priority
and MAC address together form the bridge identifier. Since the root bridge manages all
path changes, it should be located as centrally as possible due to the delay of the frames.
The value for the bridge priority is a whole multiple of 4096 with a range of values from 0
through 61440.
● Bridge Address / Root Address

● MSTP Status
Click the check box to enable or disable this option.
● Priority
Enter the priority of the port. The priority is only evaluated when the path costs are the
same.
The value must be divisible by 16. If the value that cannot be divided by 16, the value is
automatically adapted.
Range of values: 0 - 240.
The default is 128.
● Cost Calc.
Enter the path cost calculation in the input box. If you enter the value "0" here, the
automatically calculated value is displayed in the next box "Path Costs".
● Path cost
The path costs from this port to the root bridge. The path with the lowest value is selected
as the path. If several ports of a device have the same value, the port with the lowest port
number is selected.
If the value in the "Cost Calc." box is "0", the automatically calculated value is displayed.
Otherwise, the value of the "Cost Calc." box is displayed.
The calculation of the path costs is largely based on the transmission speed. The higher
the achievable transmission rate, the lower the value for the path costs will be.
Typical values for rapid spanning tree are as follows:
– 1000 Mbps = 20,000
– 100 Mbps = 200,000
– 10 Mbps = 2,000,000
The values can, however, also be set individually.

Loop detection
With the "Loop detection" function, you specify the ports for which loop detection will be
activated. The ports involved send special test frames - the loop detection frames. If these
frames are sent back to the device, there is a loop.
A "Local loop" involving this device means that the frames are received again at a different
port of the same device. If the sent frames are received again at the same port, there is a
"remote loop" involving other network components.
Note
A loop is an error in the network structure that needs to be eliminated. The loop detection
can help to find the errors more quickly but does not eliminate them. The loop detection is
not suitable for increasing network availability by deliberately including loops.
Note
Note that loop detection is only possible at ports that were not configured as ring ports or
standby ports.

Link aggregation
Bundling network connections for redundancy and higher bandwidth
Link aggregations according to IEEE 802.3ad allow several connections between
neighboring devices to be bundled to achieve higher bandwidths and protection against
failure.
Ports on both partner devices are included in link aggregations and the devices are then
connected via these ports. To assign ports (in other words links) correctly to a partner
device, the Link Aggregation Control Protocol (LACP) from the IEEE 802.3ad standard is
used.
Up to 8 link aggregations can be defined. A maximum of 8 ports can be assigned to each link
aggregation.
Note
When a port is assigned to a link aggregation but is not active (e.g. link down), the values
displayed may differ from the values configured for the link aggregation.
If the port in the link aggregation becomes active, individual port configurations such as DCP
forwarding are overwritten with the configured values of the link aggregation.

have really been learned. Only nodes that send packets during the learning phase are found.
By subsequently enabling the Port Lock function, only packets from the nodes known after
the end of the learning phase (static unicast entries) will be accepted at the relevant ports.
Note
If the Port Lock function was already active on individual ports prior to the automatic learning

Reducing network load
In contrast to unicast frames, multicast frames represent a higher load for the device.
Generally, multicast frames are sent to all ports. The following options are available for
reducing the load caused by multicast frames:
● Static entry of the addresses in the multicast filter table.
● Dynamic entry of the addresses by listening in on IGMP parameter assignment frames
(IGMP Configuration).
● Active dynamic assignment of addresses by GMRP frames.
The result of all these methods is that multicast frames are sent only to ports for which an
appropriate address is entered.
The "Multicast" menu item, shows the multicast frames currently entered in the filter table
and their destination ports that the user set in the parameters.
Dependency on the "Base bridge mode"

Management ACL
Description of configuration
On this page, you can increase the security of your device. To specify which station with
which IP address is allowed to access your device, configure the IP address or an entire
address range.
You can select the protocols and the ports of the station with which it is allowed to access
the device.
Description of the displayed boxes
Note
Before you enable this function, note the following
A bad configuration on the "Management Access Control List" page can result in you being
unable to access the device. You should therefore configure an access rule that allows
access to the management before you enable the function.
The page contains the following boxes:
● Management ACL
Enable or disable access control to the management of the IE switch.
As default, the function is disabled.
Note
If the function is disabled, there is unrestricted access to the management of the IE
switch. The configured access rules are only taken into account when the function is
enabled.
● IP Address
Enter the IPv4 address or the network address for which the rule will apply. If you use the
IPv4 address 0.0.0.0, the settings apply to all IPv4 addresses.

Steps in configuration
Note
Before you enable this function, note the following
A bad configuration may mean that you can no longer access the device. You can then only
remedy this by resetting the device to the factory defaults and then reconfiguring. You should
therefore configure an access rule that allows access to the management before you enable
the function.
Note
Keep to the order
The order in which you create the ACL rules corresponds to the order in which the rules are
checked. As soon as a rule matches, it is used. The following rules are ignored.
Create new rule
1. Enter the IP address address in the "IP Address" input box.
2. Enter the subnet mask in the "Subnet Mask" input box.
3. Click the "Create" button to create a new row in the table.
4. Configure the entries of the new row.
5. Click the "Set Values" button to transfer the new entry to the device.
Enabling function
1. Select the "Management ACL" check box.
2. Click the "Set Values" button to enable the configured access rules.
Change rule
1. Configure the data of the rule you want to change.
2. Click the "Set Values" button to transfer the changes to the device.

Downloading new firmware using TFTP without WBM and CLI
Firmware
The firmware is signed and encrypted. This ensures that only firmware created by Siemens
can be downloaded to the device.
Pressing the "RESET" button
To load new firmware, you require the "RESET" button. When pressing the button,
remember the information in the operating instructions (Page 7).
Press the button on the SCALANCE XB-200 with only slight force.
Press the button on the SCALANCE XP-200 as far as the pressure point.
Procedure with Microsoft Windows
Using TFTP, you can supply a device with new firmware even when it cannot be reached
using WBM or CLI. This section explains the procedure based on the example of Microsoft
Windows.
Follow the steps below to load new firmware using TFTP:
1. Turn off the power to the device.
2. Press the "RESET" button and reconnect the power supply to the device while holding
down the button.
3. Hold down the button until the red fault LED "F" starts to flash.
4. Release the button as long as the red error LED is still flashing..
Note
This time only lasts a few seconds.
The bootloader of the device waits in this status for a new firmware file that you can
download by TFTP.
5. Connect a PC to port 0.1 via an Ethernet cable.
6. Assign an IP address to the device using DHCP or the Primary Setup Tool.

Troubleshooting/FAQ
6.2 WBM message: SINEMA configuration not yet accepted
7. Open a Windows command prompt and change to the directory where the file with the
new firmware is located and then execute the following command :
tftp -i <IP address> put <firmware file>
Note
You can enable TFTP in Microsoft Windows as follows:
"Control Panel" > "Programs and Features" > "Turn Windows features on or off" > "TFTP
Client".
8. Once the firmware has been transferred completely to the device and validated, there is
an automatic restart on the device. This may take several minutes.
6.2
WBM message: SINEMA configuration not yet accepted
When the following message is displayed an error has occurred transferring the
configuration from STEP 7 Basic / Professional to the device:
"SINEMA Configuration not accepted yet. With restart of device, all configuration changes
will be lost."
One possible cause is, for example, that during transfer the device was not reachable.
If you now change a setting in the WBM, these changes are lost when the device restarts.
Solution
1. Open the relevant STEP 7 project in STEP 7 Basic / Professional
2. Open the project view.
3. Select the device in the project tree.
4. Select the "Go to network view" command in the shortcut menu.
5. Select the device in the network view.
6. In the shortcut menu of the selected device select the command "SCALANCE
configuration > Save as start configuration".
Result
The configuration is saved on the device. The message is no longer visible in the WBM. A
configuration change in the WBM is no longer lost due to a restart of the device reboot.
