Preface
Biological Compatibility
With regard to the question of whether electromagnetic fields (for example in association with industrial wireless LANs) can put human health at risk, we refer to a
publication of BITKOM (German Association for information Technology, Telecommunication and New Media e. V) dated December 2003:
"The same regulations for the protection of health for all other radio applications also apply to WLAN devices. These regulations are based on the protection concept of ICNIRP2 or the corresponding recommendation of the
European Council.
The independent German radiation protection commission (SSK) was commissioned by the federal German ministry of the environment to investigate
the possible dangers - thermal and non-thermal - resulting from electromagnetic fields and came to the following conclusions3:
"The SSK comes to the conclusion that even after evaluation of the latest
scientific literature, there is no new scientific evidence regarding proven adverse effects on health that causes any doubt regarding the scientific
evaluation on which the protection concept of the ICNIRP or the European
Council recommendation is based."
The SSK also concludes that below the current limit values, there is also no
scientific suspicion of health risks.
This evaluation agrees with that of other national and international scientific
commissions and with that of the WHO (www.who.int/emf).

Notice
If the LED for the WLAN interface does not light up green during startup although it
is activated, then initialization of the interface was unsuccessful.
This can occur, in particular, when the operating temperature has not yet been
reached. If the SCALANCE W 700 products are started up in negative temperatures, waiting times of up to 15 minutes are possible.
Configuration Information on the C-PLUG
The C-PLUG is used to transfer the configuration of the old device to the new device when a device is replaced. When the new device starts up, it continues 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.
Replacing the C-PLUG
Follow the steps below to replace a C-PLUG in a SCALANCE W744:
1.
Remove the old SCALANCE W744 from its mounting and open the sealing
screw on the rear with a coin or broad screwdriver.
2.
Remove the C-PLUG.
3.
Open the sealing screw of the new device in the same way and insert the CPLUG of the old device.
4.
Replace the sealing screws of both devices.
If a new C-PLUG is inserted in a SCALANCE W744-1PRO, the configuration
stored locally on the SCALANCE W744-1PRO is saved to the C-PLUG. If an incorrect C-PLUG (for example from another device or a damaged plug) is inserted, the
SCALANCE W744 signals an error with the red LED. The user then has the choice
of either removing the C-PLUG again or selecting the option to reformat the CPLUG and use it.

Notes on Power Supply and Grounding
!
Warning
The SCALANCE W744-1PRO device is designed for operation with safety extralow voltage (SELV). This means that only safety extra-low voltages (SELV) with
limited power source (LPS) complying with IEC950/EN60950/ VDE0805 can be
connected to the power supply terminals.
The power supply unit to supply the SCALANCE W744 must comply with NEC
Class 2 (voltage range 18 - 32 V, current requirement 1 A)
The subject unit is to be supplied by a Class 2 power source complying with the
requirements of the National Electrical Code, table 11 (b). If power is redundant
supplied (two individual power sources) the power sources together should comply
with the requirements of the National Electrical Code, table 11 (b).
Exceptions:
Power supply with PELV (according to VDE 0100-410) is also possible if the generated rated voltage does not exceed the voltage limits 25 V AC or 60 V DC.
Power supply by a SELV power source (according to IEC 60950) or PELV power
source (according to VDE 0100-410) without limited power is also permitted if
suitable fire protection measures are taken by:
-
Installation in a cabinet or suitable enclosure
-
Installation is a suitably equipped, closed room
Caution
There must be no potential difference between the following parts, otherwise there
is a risk that the device could be destroyed:
• Ground potential of the power supply and the ground potential of the antenna
ground.
• Ground potential of the power supply and a grounded enclosure.
• Ground potential of the power supply and the ground potential of the device
connected to Industrial Ethernet (for example, PC, AS-300, AS-400 etc.).
Connect both grounds to the same foundation earth or use an equipotential bonding conductor.

Assembly and Connectors
Securing the Housing
There are two ways of securing the housing:
● Use the holes in the housing to screw the device to the wall or on a horizontal
surface.
● Install the SCALANCE W788 on a 90 mm long, vertically mounted piece of
standard rail (S7-300). In this case, the standard rail serves as an
adapter between the wall and SCALANCE W788. If you want to install the
SCALANCE W788 along with a PS791-1PRO, a 150 mm long standard rail is
necessary.
Connectors for the Power Supply and for Ethernet
The SCALANCE W788 is attached to Ethernet via a hybrid socket on the front of
the housing (position A in Figure 3.1). This port also has contacts for the operating
voltage.
Note
If you do not use the hybrid socket, this must be covered with a protective cap,
otherwise IP65 protection is lost. A suitable protective cap is available as an accessory. If you do not use the M12 connector, the supplied protective cap must be
fitted to retain IP65 protection.

Cabling for Power Supply and Ethernet
3.3.1
General Notes
Suitable Cables
The following cable variants are available to connect a SCALANCE W-700 to the
power supply and to Ethernet:
● IE hybrid cable 2x2 + 4x0,34 (order no. 6XV1870-2J)
The two data wire pairs are separately shielded. This cable is particularly suitable for assembly with the IE IP67 hybrid connector.
● IE FC TP standard cable 4x2 GP (order no. 6XV1870-2E)
IE FC TP flexible cable 4x2 GP (order no. 6XV1870-2H)
In these cable types, two wires are twisted. All for pairs of wires are inside a
common shield.
Cable Selection and Interference Exposure
A decisive factor in the selection of a cable type is the electromagnetic interference
to which the current lines between the power supply and the FC RJ-45 modular
outlet are subjected. Due to the separate shielding of the data wires, such interference has less effect on the data transmission on a hybrid cable than on TP standard cable or TP flexible cable.

Introduction
Initial Assignment of an IP Address
An initial IP address for the SCALANCE W744 cannot be assigned using Web Based Management or the Command Line Interface because these configuration
tools require that an IP address already exists.
The initial IP address can be obtained only over DHCP or assigned using the Primary Setup Tool. The Primary Setup Tool is capable of assigning such an address
to unconfigured devices without an IP address. The only condition is that the devices can be reached over Ethernet.
Operating Systems Supported
The Primary Setup Tool can be installed and used with the following operating systems:
● Windows XP Professional
● Windows 2000 Professional SP2
DLC Protocol
The Primary Setup Tool uses the DLC protocol for communication with the modules. This protocol is not supplied with Windows XP and must be installed extra for
this operating system.
Follow the steps below to check whether or not the DLC protocol exists on your
computer:
1.
Select the menu command Start > Settings > Control Panel >Network and Dial-Up Connections.
2.

Contents of this Chapter
This chapter explains the possible settings for the SCALANCE W788. For a detailed description of the individual elements of a page, refer to the online help.
As an alternative, you can also configure the device using the Command Line Interface (CLI). This allows remote configuration over Telnet.
This chapter describes both configuration methods together because the menu
structure of Web Based Management is the same as the structure of the CLI commands.
Note
You should only use the command line interface if you are an experienced user.
Even commands that bring about fundamental changes to the configuration are
normally executed without a prompt for confirmation

Advanced Submenu
Configuring Transmission Characteristics
On this page, you can specify details of the transmission characteristics. You only
need to adapt the parameters on this page if the SCALANCE W744 cannot be used as it is intended with the default settings.
Transmit Power
In the Transmit Power list box, you can specify the output power of the
SCALANCE W744. It may be necessary to reduce the transmit power when using
antennas to avoid exceeding the maximum legal transmit power. Reducing the
transmit power effectively reduces cell size.
Beacons
Beacons are packets that are sent cyclically by a SCALANCE W744 to inform clients of its existence. In the Beacon Interval text box, you specify the interval at
which the SCALANCE W744 sends beacons.
RTS/CTS
RTS/CTS (Ready To Send/Clear To Send) is a method of avoiding collisions
based on an exchange of status information prior to sending the actual data. To
minimize network load resulting from the additional protocol exchange, this method
is used only when a packet size that you select with the RTS/CTS Threshold is exceeded.
Operating Instructions SCALANCE W 744-1PRO
C79000-G8976-C185-03
65
Configuration Using Web Based Management and the Command Line Interface
Fragmentation
The Fragmentation Length Threshold parameter specifies the maximum package
size transferred on the radio link. Large packets are divided up into small packets
prior to transmission and then reassembled into the original size after they have
been received. This can be beneficial if the transmission quality is poor because
larger packets are more difficult to transmit. This does, however, result in a poorer
data throughput.
Repetitions
There are two situations in which packets are repeated. The hardware repetition is
performed by the WLAN chip itself when it tries to repeat an unacknowledged packet immediately. The number of attempted repetitions is specified with the HW
Retry number parameter.
If the number of retries is reached without success, the packet is temporarily withdrawn and all other packets in the buffer are sent first. Following this, transmission
of the packet is attempted again. The number of such repetitions is specified with
the SW Retry number parameter.
Using Use SW Retry, the software repetition mechanism can be disabled.
Antennas
The Antenna Mode list box specifies the use of antennas. The Diversity setting
takes the best of the two antennas for the data transmission. For each WLAN interface, both antennas must be connected. If only one antenna is connected, this
must be selected here. The second antenna socket must also have a 50 Ω terminator fitted.
Scanning for Access Points
While the client is connected to an access point, it scans for other access points in
the background with which it connects when necessary. There are three modes for
scanning access points that can be selected in the Background scan mode list box.
If you set Disable, there is no scan for access points while the client is connected.
If you set Scan if Idle, there is a scan for access points when no data transfer takes
place for a certain time.
If you set Scan Always, access points are scanned continuously.
The Background scan interval parameter specifies the interval at which further access points are scanned.
To optimize the scanning for further access points, you can specify channels for
the client on which other access points can be found. To allow this, the Background Scan Ch.Select check box must be set and the channels of the other access point is entered in the Background Scan Channels text box. Enter the channels separated by blanks.

If the client finds a better access point, it attempts to connect to it. Before it changes, the new access point must be better than the current access point by a certain
value. The threshold at which the client changes to the new access point can be
specified with the Roaming threshold parameter.

management and control data (RTS/CTS frames, beacons) are sent in the 802.11g
mode. You can also specify that the SCALANCE W744 only supports 802.11gcompatible devices.
Handling 802.11b Clients
The access point automatically detects whether 802.11b clients exist in the environment. To avoid 802.11g packets colliding with 802.11b packets, the access
point can use the RTS/CTS method.
With the 802.11g CTS Mode list box, you specify the use of RTS/CTS (only in the
access point mode).
0 do not use RTS/CTS.
1 always use RTS/CTS with 802.11g packets.
2 only use RTS/CTS when there are 802.11b clients in environment.
You can set the data rate for RTS/CTS frames in the 802.11g CTS Rate list box.
With the 802.11g CTS Type list box, you specify whether a CTS or RTS/CTS is
sent.
802.11g Expansions
With the 802.11g Short Slot Time parameter, you specify whether or not the short
slot time is used. This short slot time should be supported by all
newer clients.
The 802.11g Basic Rate list box specifies the minimum data rate that must be supported by clients before they can connect to the access point (only in the access
point mode).
With the 802.11g Only Mode parameter, you can specify that only 802.11g clients
can log on at the access point and also that only 802.11g rates are permitted (only
in the access point mode).

Basic Wireless Menu Command
Authentication
You can set the following options in the Authentication Type box:
● Open System
There is no authentication.
● Shared Key
WEP authentication with keys stored on the device. In this case, you must
specify a key in the Keys menu.
● WPA (Radius)
WPA authentication over an external RADIUS server (802.1x).
● WPA-PSK
WPA authentication without Radius server.
● 802.1x
Port-related access control with a Radius server. With this method, the client
must authenticate itself with a RADIUS server based on certificates. If the authentication is successful, the ES server generates a pair of keys that is used
for encryption of communication.

Encryption
You can only disable encryption (deselect the Encryption check box) if you have
selected Open System or 802.1 with Mixed Mode for the authentication. All other
security methods include both authentication and encryption.
Encryption Methods for WPA
If you have selected WPA authentication (both PSK and Radius), you have the following alternatives in the Cipher box:
● AES (Advanced Encryption Standard)
Encryption according to the Rijndael algorithm.
● TKIP
Use of dynamic keys. Starting from an initialization key, a new key is generated
for each data packet.
Additional Entries for WPA-PSK
To use the WPA-PSK scheme, you must enter a string in the Pass Phrase box that
is used by the SCALANCE W744 to initialize dynamic key generation.

Specifying the WEP/AES Key
To allow you to enable the encryption for the Open System and Shared Key authentication methods, you must first enter at least one key in the key table.
You can also create keys for WDS Redundancy and ACL Private (these are not
supported by all clients for ACL).
Note
When operating the CP 7515, note the following when configuring the keys on the
SCALANCE W744:
The ACL key and the WEP key must be of the same length since the CP 7515 only
allows a uniform key length. If the Windows-specific program Zero-Config is used
even the keys must be the same.

The Bridge Menu
Introduction
A bridge is a network component that connects two networks. A bridge is not dependent on the protocol; management of the data packages is based on the physical address of the network nodes (MAC address).
The SCALANCE W744 provides bridge functionality because it handles data exchange between wired and wireless Ethernet. The following sections describe the
functions that are available and how you configure and use them.
Deleting Aged Bridge Information
The SCALANCE W744 saves the information about which MAC address can be
reached over which port in a learning table. Entries in this list are deleted automatically when there is no further data transfer for the corresponding MAC addresses. You can decide the length of time after which addresses are deleted if no
data is sent using the Aging Time parameter on the start page of the Bridge menu.

power down on M12 or the Ethernet power connector.
snScalanceWPowerLineUp
32
snScalanceWChangedPowerLine - The power line where the
last power up occurred. 1-M12,
2-Ethernet Power
This is generated at the power
up at M12 or Ethernet power
connector
snScalanceWFault
41
snScalanceWFaultValue -
This is generated if the
snScalanceWFaultValue variable is changed.
Fault value:
0 = no fault,
bit 0 = power M12 is off,
bit 1 = link down,
bit 2 = internal error,
bit 19 = Link Check error,
bit 20 = IP Alive broken,
bit 21 = power ethernet is off,
bit 22 = Cold/warm start,
bit 23 = C-PLUG error,
bit 24 = iQoS error,
bit 25 = Redundancy error"

51
snScalanceWIQOSValue - Description of the last snScalanceWIQOS trap
snScalanceWLinkCheckOff
81
snScalanceWLinkCheckValue Description of the last snScalanceWLinkCheckOff Trap
This is generated if a timeout
occurs with a client monitored
with Link Check.
snScalanceWLinkIntegrityOn
82
snScalanceWLinkCheckValue Description of the last snScalanceWLinkCheckOn trap
This is generated if a client monitored with Link Check logs on
again at the AP following a timeout.
snScalanceWClientAuthenticated
85
SnScalanceWClientsIndex - An
index of the client in the snScalanceWClients table
This is generated when a client
logs on at the AP.
snScalanceWClientDeAuthenticated
86
SnScalanceWClientsIndex - An
index of the client in the snScalanceWClients table
This is generated when a client
logs off from the AP.

ACL
Access Control List with MAC addresses with the right to access the
wireless network
Ad hoc network
Wireless network between individual devices (point-to-point)
AES
Advanced Encryption Standard, Encryption according to the Rijndael
algorithm.
EAP
Extensive Authentification Protocol. Authentication protocol.
Hidden node problem
Two nodes are arranged in a wireless cell so that they are outside
their own transmission range. If they both access the medium at the
same time, collisions result.
IEEE
Institute of Electrical and Electronics Engineers
IEEE 802.11
Standard for wireless networks in the 2.4 GHz range with transmission rates of up to 2 Mbps.
IEEE 802.11a
Standard for wireless networks in the 5 GHz range with transmission
rates of up to 54 Mbps.
IEEE 802.11b
Standard for wireless networks in the 2.4 GHz range with transmission rates of up to 11 Mbps.
IEEE 802.11g
Standard for wireless networks in the 2.4 GHz range with transmission rates of up to 54 Mbps.
IEEE 802.11h
The IEEE 802.11a standard expanded by TPC and DFS.

Glossary
IEEE 802.1x
The heart of the standard is the use of a Radius server as the authentication server. In addition to this, in IEEE 802.1x, the entire communication is encrypted.
RADIUS
Remote Authentication Dial - In User Service for secure communication networks
Roaming
Free movement of wireless LAN nodes even beyond the boundaries
of an access point's cell. The nodes and can move from one cell to
the next without any noticeable interruption.
RTS/CTS
Request to send/Clear to send. Scheme for avoidance of collisions.
SNMP
Simple Network Management Protocol. Standardized protocol for
transporting network management information.
TKIP
Temporal Key Integrity Protocol. Scheme for cyclic changing of keys
in WLANs.
WBM
Web Based Management. HTTP-based configuration method in which
an HTTP server is used in the SCALANCE W744.
WDS
Wireless Distribution System. Radio links for connecting the access
points for an extended service set (ESS)
WEP
WEP (Wired Equivalence Privacy) is an optional part of the IEEE
802.11 standard. WEP specifies methods of authentication and encryption working with fixed keys stored on the device. All devices that
want to access a network in which WEP is used must first be supplied
with the same keys. The keys can only be changed manually.
Wi-Fi
Wireless Fidelity. Specification for wireless networks.
WPA
WPA (Wi-Fi Protected Access) is a method specified by the Wi-Fi
Alliance to close security gaps in WEP. Authentication using a server
is stipulated (802.1x). The dynamic exchange of keys at each frame
introduces further security. The type of encryption can be TKIP or
AES.

Glossary
WPA-PSK
WPA-PSK is a weakened form of WPA. In this method, authentication
is not established by a server but is based on a password. This password must be configured manually on the client and server. Wherever
possible, you should change to the WPA method to achieve greater
security.
