2. SCALANCE – scalable performance2
Totally Integrated Automation from Siemens demonstrates in
a host of successful applications around the world the extent
to which integrated solutions can be created today with
shared tools and standardized mechanisms. Selective further
development of industrial communication with SIMATIC NET
is linked with this at a fundamental level.
A pioneering milestone in this development is SCALANCE, the
generation of active network components for establishing in-
tegrated networks.
These active network components are optimally coordinated
with each other. They have been designed for harsh industrial
environments and enable integrated, flexible and secure set-
up of a high-performance network.
Industrial Ethernet switching components
The communication network is of the utmost importance for automation solutions.
With SIMATIC NET, Siemens offers Industrial Ethernet switching components for
structuring networked machines and plants, and for integrating into the overall cor-
porate network. A graded portfolio of switches (SCALANCE X) and communications
processors with integral switch enables optimum solutions for all types of switching
tasks, and not only in harsh industrial environments.
Industrial Wireless LAN (IWLAN)
Thanks to wireless communication with programmable controllers, even greater
flexibility is achieved, maintenance work is simplified, and service and standstill
times reduced. The IWLAN solution from Siemens Industry makes these advantages
available through a coordinated portfolio of WLAN equipment for industrial use,
even for fail-safe communication in the context of operator and machine safety.
This includes IWLAN access points and client modules (SCALANCE W), wireless
interfaces for PROFIBUS and distributed I/O, mobile operator panels, planning soft-
ware, and extensive accessories.
Industrial Ethernet Security
By integrating into the corporate network, the increased wired and wireless net-
working of industrial plants enables a degree of integration and openness that pro-
vides many benefits such as remote access to plant sections over the Internet. How-
ever, this also results in certain risks with regard to data security. With its industrial
security concept, SIMATIC NET offers a safety solution that is specially designed for
industrial automation engineering and that satisfies the specific requirements of
this application environment. The security modules (SCALANCE S) and software are
easy to handle, and reaction-free integration into existing networking concepts is
possible.

3. Industrial Wireless LAN from Siemens 3
Industrial Wireless LAN from Siemens
Reliable, rugged, and secure
The key to market success lies in the provision and availability
of information, no matter when or where you need it. Thanks
to the use of mobile devices linked via wireless data networks
(e.g. wireless LAN), the efficiency of processes can be signifi-
cantly improved. The primary benefit of wireless solutions is
the simple and flexible availability of mobile or hard to access
stations.
Mobile communication increases a company's competitive-
ness, as it helps achieve greater flexibility through the use of
wireless communication to automation devices and industrial
terminal devices. As a result you can simplify maintenance
work, reduce service costs and downtimes and deploy your
personnel optimally.
The WLAN IEEE 802.11 standard does not have the
necessary specifications for use in an industrial environment.
SIMATIC NET made several enhancements to radio products in
accordance with the requirements of automation, thus creat-
ing the Industrial Wireless LAN (IWLAN).
Industrial Mobile Communication stands for wireless commu-
nication in industry. It is based on international standards,
such as IEEE 802.11 at 2.4 GHz and 5 GHz, and data transfer
rates of up to 54 Mbit/s.
The integration of wireless communication in industry is
opening up a wide range of opportunities previously not avail-
able with a wired solution: Demanding applications, such as
those with strict real-time requirements, were until recently
considered a no-go area for radio technology. The use of radio
on dynamic machines saves cabling materials and mainte-
nance costs, automated guided vehicle systems can obtain
data without the need for cables and the choice of route is not
restricted.
Part of TIA
Totally Integrated Automation (TIA) provides a complete
range of products and systems for automation in all sectors of
industry – from incoming goods through the production pro-
cess to the delivery of goods, and through all levels, from the
field level to production management right up to company
management. The tools access a common database. This
saves input costs and ensures project-wide consistency.
Possible applications
■ Automated guided vehicle systems (AGV) and over-
head monorail conveyors;
prevents wear and offers high flexibility for traffic
routing thanks to the wireless transfer of data to the
vehicles
■ Cranes;
high flexibility through access to data communica-
tion with the moving unit independent of the
location
■ Wireless access to field devices for configuration and
testing without costly adaptation of the control
cabinet
■ Communication with moving nodes
(e.g. mobile controls and devices), storage and
retrieval machines, conveyor systems, conveyor
belts, rotating machines, trucks
■ Wireless linking of communication segments for
rapid commissioning or for cost-effective network-
ing, where otherwise the installation of cables would
result in considerable costs (e.g. public highways,
rivers, lakes, railways)
■ Water supply and waste-water disposal;
monitors and controls water catchment, pumping
stations and water treatment plants, for example, via
GPRS, mobile phone and the Internet

lish the wireless data transfer. This avoids the costly cabling
involved in setting up a communicationsystemandthe result-
ing wear, which leads to prolonged failures and high costs.
• Thanks to their industry-standard design with IP65 degree
of protection, the IWLAN components are protected
against water and dust and can be used outdoors at tem-
peratures as low as -20 °C.
• The cyclic execution of data packets permits a strict real-
time and reliable radio connection. Interference within the
industrial environment does not affect the radio connec-
tion, as redundancy mechanisms, packet repetitions and
modern encryption mechanisms ensure a reliable and se-
cure data transfer.
• Within the established radio field, you can use the
277F IWLAN Mobile Panel terminal device to access up-to-
date data online from any location
• The SNMP OPC server makes it easy to integrate MS Office
applications in the solution. As a result, the solution can
provide important communication parameters for the com-
munication system.

Automotive production
Task specification
• The number of nutrunners used in vehicle final assembly
should be reduced. The existing solution uses one nutrun-
ner for each cycle and each barcode detection
• Since the hard-wired solution with slip rings results in high
maintenance costs, a reliable wireless communication so-
lution is required to increase efficiency and reduce setup
times
• The products should be industrialized and available world-
wide
• Investment protection is also required by ensuring the
long-term availability of the components used
Solution
• The IWLAN RCoax Cable – a silicon-free leaky wave cable –
is used along the coding rail to enable wireless data trans-
fer. It generates a defined conical and reliable radio field,
which is easy to route. The RCoax Cable is therefore ideal
for use in demanding radio environments and in all types of
rail-mounted vehicles.
• The feed-in station for the RCoax Cable consists of
SCALANCE W788-1RR IWLAN access points in accordance
with IEEE 802.11 b/g (2.4 GHz), with data transfer rates of
up to 54 Mbit/s.
• The SCALANCE W747-1RR client module is installed as a
mobile station. As a result, the same mobile unit can be
used for all applications, and consequently one mobile
nutrunner can be employed for multiple cycles.
• In addition, the use of SCALANCE W747-1RR offers the
option of using up to eight terminal devices.
• The terminal devices and the SCALANCE
W747-1RR client module in the hanger are connected to a
SCALANCE X208PRO Industrial Ethernet switch using M12
Ethernet technology.
System solution for nutrunner controllers with RCoax Cable and
SCALANCE W747-1RR

nutrunners
• Reduction in maintenance costs and downtimes thanks to
a reliable wireless and wear-free data transfer to mobile
communication partners
• Decreased downtimes in case of failures owing to the use
of the C-PLUG (Configuration Plug); devices can be re-
placed without the need for specialist personnel or a pro-
gramming device
• Reduction of operator activity, for example scanning, cycle
transfer, travel time allows higher throughput
• Easy to change models, dependent only on material logis-
tics
• Possibility of integrating additional quality assurance appli-
cations
• Complete nutrunner data can be loaded via the IWLAN line

which receives the data from the individual PROFINET sub-
networks
• The data from the PROFINET subnetworks is bundled by
SCALANCE W744-1PRO client modules
• SCALANCE X208 switches are used for the wireless connec-
tion to the control level of the PROFINET network. These are
each equipped with eight RJ45 ports and form the point of
intersection for the PROFINET IO controller and the
ET 200pro
• The FastConnect system with IE FC Standard Cable and
IE FC Flexible Cable is used with the IE FC RJ45 plugs to
create the network
Benefits
• The radio network's excellent method of operation and

Harbor plant / Container logistics
Task specification
• A rugged radio system should be installed for outdoor use
in a container handling system at the port of Hamburg.
With this solution, containers should be loaded and un-
loaded via IWLAN using automated guided vehicle systems
(AGVS). Both the driving area and the lanes between the
storage blocks should be inspected reliably and economi-
cally, the system should be expandable and be insensitive
to interference even as the number of vehicles rises.
• The system should be reliable and work together with other
networks that are already in place, as the changeover to the
new system can only take place step by step.
• Solid, expert support should be provided by the manufac-
turer during implementation and installation.
Benefits
• The radio network's excellent method of operation and
IEEE 802.11b (11Mbit/s) radio standard ensure inter-
ference-free operation
• Savings in costs, as the existing infrastructure (masts and
antennas) could be retained
• Targeted on-site support during implementation and com-
missioning
• Expandable radio network for further investments in the
future
Solution
• For the inspection of the driving area and lanes in-be-
tween, 11 SCALANCE W786-1PRO access points are used to
operate 54 automated guided vehicle systems (AGV), guar-
anteeing optimum coverage of the radio area involved. The
access points with IP65 degree of protection are resistant to
salt spray and designed for operation at temperatures rang-
ing from -40 °C to +70 °C. They therefore ensure reliable op-
eration in the outdoor area of a harbor plant .
• The SCALANCE W744-1 client modules with ANT795-6MN
antenna are used in the automated guided vehicle systems
to ensure compact integration.
• The radio network is based on the IEEE 802.11 standard
and is therefore reliable and free from interference. The
roaming function enables the automated guided vehicle
systems to move freely within the radio field.
• Coordination with existing networks was already taken into
consideration during advance planning, and successfully
put into practice.
• Under consideration of the existing infrastructure, a new,
more powerful antenna was installed on the vehicles, en-
suring that the connection is not interrupted when contain-
ers of various sizes are used.

Water supply
Task specification
• The entire water supply for a community should be moni-
tored and controlled in one integrated system. To this aim,
wells and pumping stations for the water catchment must
be networked, and water treatment plants, pumping sta-
tions and elevated storage reservoirs for the water supply
must be integrated in the system.
• The entire system should be monitored and controlled
from a central waterworks that acts as the control center.
Solution
• All process stations are controlled locally by a
SIMATIC S7-200.
• WLAN is used to connect the well stations and elevated
storage reservoirs directly to WinCC or WinCC flexible in the
main control center (a line-of-sight connection over an un-
inhabited area permits longer distances to be covered)
• More remote stations can be reached via GPRS.
The SINAUT MD720-3 modem is linked to a SIMATIC S7-200
via a serial interface and fitted with a GSM antenna.
• The SINAUT MICRO SC program package manages the con-
nection of the S7-200 stations linked via GPRS and is con-
nected to the control and observation system via OPC.
• Operating personnel can directly intervene in the process,
for example to switch pumps on/off or actuate valves, using
control commands and by inputting set points.
• The optional "Alarm Control Center Micro Edition" OPC
client allows contingency personnel to be informed by text
message if parameters are exceeded. If an employee can-
not be reached, a different employee is automatically noti-
fied, until the system receives a call back from the service
personnel.
Benefits
• Efficient, cost-effective control of the entire drinking water
supply system via a single main control center
• Easy installation and low investment costs owing to the use
of an existing GSM/GPRS radio network for a permanent
online connection
• Very low operating costs, thanks to:
- Low-cost GPRS volume call rates and low mandatory data
volume (e.g. 2 – 4 MB per month)
- The mobile phone provider is responsible for servicing
and maintaining the communication network
- Standard SIM cards can be used. There are no monthly
charges for a VPN from the mobile phone
provider, because the security functions are integrated in
the GSM/GPRS modules
• Low investments costs and flexible wireless expansion with
Industrial Wireless LAN means that applications requiring a
broader transmission bandwidth (camera, VoIP, etc.) can
also be incorporated

Task specification
• Remote monitoring and control of a sewage plant
• Operating data and time stamps should be recorded and
transferred using a low-cost GPRS/Internet connection
• Automatic notification of contingency staff in the event of
critical conditions at the plant
Solution
• A SCADA computer with WinCC is used in the main control
center, enabling all process states of distributed stations
(sewage treatment plants, rain overflow basins, etc.)
to be displayed and archived, and all connected assemblies
to be remotely controlled.
• The VPN function of SCALANCE S encodes and decodes all
the data that needs to be transferred. Data transfer to and
from the stations is achieved via GPRS/Internet or via the
local Wireless LAN network.
• SIMATIC S7-300 controllers with TIM 3V-IE are used in
the stations. The GPRS router MD741-1 and SCALANCE
W786-1PRO access point are used as data communication
equipment.
• Contingency personnel are notified by text message or fax
in the event of alarms or important process events (e.g. if
limit values are exceeded). If an employee cannot be
reached, the escalation strategy of the notification system
continues the attempt to notify other employees until the
system has received a positive acknowledgement by ser-
vice personnel.
Benefits
• Easy installation and low investment costs because an
existing radio network is used
• Low operating costs, thanks to:
- Low-price GPRS volume call rates
- The mobile phone provider is responsible for servicing
and maintaining the communication network
- Standard SIM cards can be used. There are no monthly
charges for a VPN from the mobile phone
provider, because the security functions are integrated in

Wireless communication for
the industrial sector
Reliable, rugged, secure
IWLAN is especially suitable for demanding industrial applica-
tions that require end-to-end, reliable and secure radio com-
munication:
Integrated communication
Perfectly matched communication produces enable smooth
operation from the field to the office, from wired PROFIBUS
and Industrial Ethernet to the wireless world of Industrial
Wireless LAN. This significantly increases the level of effective-
ness, since all production and management stations and sys-
tems can be used end-to-end.
By connecting an IWLAN access point (e.g. SCALANCE
W788-1PRO) to the Ethernet network you can produce a radio
connection to the mobile stations. The latter are connected
via radio or a client module, e.g. SCALANCE W746-1PRO, to
which the mobile station is connected with a cable.
Existing controllers and processes can be accessed without in-
curring excessive additional cabling costs.
By using a radio connection and the roaming function, you
can move freely within the range of the Industrial Wireless
LAN network and monitor the process from various locations.

15. Wireless communication for the industrial sector 15
Our industrialized products for wireless communication distin-
guish themselves through their reliability, ruggedness, suit-
ability to harsh industrial environments, and security.
Reliability
• Redundancy mechanisms and packet repetitions
• A dedicated data transfer rate prevents delays when
accessing the data traffic or even production downtimes.
• Defined transfer times (real-time requirements) and a
dedicated data transfer rate are achieved by the use of real
time and provide the stations with cyclic radio traffic
• Redundant network concepts: Radio channels can be de-
signed redundantly with a changeover time of a few milli-
seconds, so that the application is not influenced by packet
repetitions or interference in the radio channel.
• Monitoring of the radio connection
• The C-PLUG swap medium saves engineering and configu-
ration data, enabling the device to be replaced quickly and
without the need for specially trained personnel.
• The iPCF function allows you to rapidly transfer mobile sta-
tions from one radio field to the next to prevent
interruption of PROFINET IO communication. You can oper-
ate multiple wireless PROFINET IO devices simultaneously
in real time.
• Access is controlled by an authentication process
Ruggedness and industrial capability
• Temperature fluctuations from -40 °C to +70 °C
• Operation in environments with dust and water (IP65)

Cabling system
The active network components are supplemented by passive
network components.
For access points with RJ45, M12 or fiber-optic connec-
tions
there are different FastConnect cables available for different
application areas.
The FastConnect system thus enables simple assembly on-site
and avoids excess lengths because the correct length can
always be assembled for RJ45, M12, or fiber-optic FC cables.
• Industrial Ethernet FC cables with special construction for
quick assembly (UL and CAT5 PLUS certification, PROFINET-
compliant)
• User-friendly stripping technology with the FC stripping
tool, enabling the outer sheath and braided shield to be re-
moved accurately in a single operation.
• FC RJ45 Plugs have a rugged metal housing that is immune
to interference, making it the ideal solution for the installa-
tion of RJ45 plugs in the field area, too (PROFINET compli-
ant).
• With FastConnect products, the prepared cables are con-
nected using cutting and clamping methods.
• The Industrial Ethernet FC Modular Outlet is also suitable
for Gigabit cabling (Cat 6).
For access points with hybrid connection
the FC RJ45 Modular Outlet with power insert is available. If
the SCALANCE W devices are to be supplied with power and
data via a cable, a hybrid cable - to be ordered separately - and
the FC RJ45 Modular Outlet with power insert must be used
(assembly in the field).
The IE FC Hybrid Cable 2x2 + 4x0.34 is available as the cable.
It is a flexible cable for conveying power and data for the IE FC
RJ45 Modular Outlet.

28. Industrial Wireless Communication 27
Industrial Wireless Communication
Advantages at a glance
■ Predictable data traffic (deterministic) and defined
response times on the radio link
■ Reliable radio link, e.g. due to redundant connection
and cyclic monitoring of the wireless path
■ Cost savings due to a separate radio network for reli-
able operation of a process as well as for critical pro-
cess data (e.g. alarm signals), as well as for non-criti-
cal communication (e.g. service and diagnostics)
■ Investment security because all products are
compatible with the internationally recognized
WLAN standard IEEE 802.11, suitable for the unli-
censed frequency bands of 2.4 GHz and 5 GHz
(ISM bands)
■ Quick commissioning of the access points with the
swap medium PRESET-PLUG
■ Reduced operating costs, because there is no wear of
rotating and moving plant sections
■ Cost-effective connection to devices which are
remote, difficult to access or in hostile environments
■ Operational reliability in the industrial environment,
e.g. thanks to a rugged housing and industrial
approvals
■ Increased plant availability through wireless data
transmission to mobile communication partners with
the leaky wave RCoax cable
■ Uniform radio network throughout the company sec-
tors for voice and data; cost savings resulting from
central management, simple installation and reliable
startup
■ Redundant power supply via Power-over-Ethernet
(48 V DC in accordance with IEEE 802.3af and
12-32 V DC or 110-230 V AC)
■ C-PLUG: Swap medium for rapid device replacement
without the need for a programming device. This pre-
vents downtimes and cuts engineering costs in the
event of access point failure. The time required for
maintenance is reduced; no trained personnel is
required in case of disturbances
■ Use also in the automobile industry, e.g. in paint
lines, thanks to silicone-free version, and certified for
explosion protection Zone 2 (ATEX)
■ Different product versions in IP30 and IP65 for differ-
ent applications; operation with WLAN controller
possible
■ Fiber-optic connection for greater distances
