Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

This document contains the CLI commands that are supported by SCALANCE W700
devices.
●Performance data 802.11abgn PCIe Minicard MPCIE-R1-ABGN-U3
This document contains information about the frequency, modulation, transmit power and
receiver sensitivity of the wireless card.
●SCALANCE W788-x / W748-1 Operating Instructions
This document contains information on installing and connecting up the following
products and their approvals:
–SCALANCE W788-1 RJ-45
–SCALANCE W788-1 M12
–SCALANCE W788-2 RJ-45
–SCALANCE W788-2 M12
–SCALANCE W788-2 M12 EEC

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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
Link (https://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers’ exposure
to cyber threats.

2.1
Network structures
The following article deals with the setting up of various network structures using access
points and clients. A client is also an access point in client mode.
Standalone configuration with access point
This configuration does not require a server and the access point does not have a
connection to a wired Ethernet. Within its transmission range, the access point forwards data
from one WLAN node to another.
The wireless network has a unique name. All the SCALANCE W700 devices exchanging
data within this network must be configured with this name.
The gray area in the graphic symbolizes the wireless range of the access point.

Wireless access to a wired Ethernet network
If one (or more) access points have access to wired Ethernet, the following applications are
possible:
●A single device as gateway:
A wireless network can be connected to a wired network via an access point.
●Span of wireless coverage for the wireless network with several access points:
The access points are all configured with the same unique SSID (network name). All
nodes that want to communicate over this network must also be configured with this
SSID.
If a mobile station moves from the area covered by one access point to the area covered
by another access point, the wireless link is maintained (roaming).
The following graphic shows the wireless connection of a mobile station over two wireless
cells (roaming).

Multichannel configuration
If neighboring access points use the same frequency channel, this can lead to longer
response times due to any collisions that may occur. If the configuration shown in the figure
is implemented as a single-channel system, computers A and B cannot communicate at the
same time with the access points in their wireless cells.
If neighboring access points are set up for different frequencies, this leads to a considerable
improvement in performance. As a result, neighboring wireless cells each have their own
medium available and the delays resulting from time-offset transmission no longer occur.
The channel spacing should be as large as possible; a practical value is 25 MHz. Even in a
multichannel configuration, all access points can be configured with the same network name.
The following graphic shows a multichannel configuration on channels 1 and 2 with four
access points.
