Industrial Wireless Communication
Forward-thinking solutions for reliable communication
Industrial communication is one of the keys to increasing
efficiency, reducing total cost of ownership, and improving productivity. The huge potential, especially of wireless
communication, opens up new perspectives here – from
partial modernization of plants, right up to optimizing
complex logistics or production processes.
But IWLAN is also being widely used in industry-oriented
applications. The high data transfer rates required there allow
applications in association with video streaming as well as the
transmission of visualization or language data. High deterministic or redundancy concept requirements can be covered
by the IWLAN infrastructure.
Siemens offers solutions for reliable automation with industrial wireless communication based on Wireless Remote
Networks, Industrial Wireless LAN, and WirelessHART.
WirelessHART
Wireless Remote Networks
Continuous communication between widely separated plant
sections in the area of water/wastewater, or high-speed
remote maintenance access to machines and plants on the
other side of the world - these are just two of the countless
ways you can reap the benefits of Wireless Remote Communication. Thanks to integration in the SINAUT telecontrol system
or an HMI/SCADA system, transferred process data is available
at any time via mobile radio.
WirelessHART is an open industry standard, developed for the
particular requirements of wireless communication at the
field level in the process industry. It meets all specific requirements for reliability, security, economy, and user-friendly
operation system-wide. With more than 30 million installed
devices worldwide, HART technology is the most frequently
used communication protocol for intelligent process instrumentation at the field level. WirelessHART is backwardscompatible with wired HART technology and thus offers maximum investment security.
Industrial Wireless LAN
Wireless solutions are increasingly becoming a matter of
course in machines and plants. In the case of high data communication requirements, Industrial Wireless LAN (IWLAN)
backs innovations like deterministic radio and the Industrial
Ethernet standard PROFINET.

IWLAN for industrial and
industry-related areas
Powerful, rugged, secure
IWLAN is especially suitable for demanding industrial applications that require end-to-end, reliable and secure radio communication:
• For implementation at industrial and automation customer
sites
• For outdoor environments with demanding climatic
requirements
• For low-cost integration in the control cabinet or in devices
Integrated communication
Perfectly matched communication products 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 effectiveness, since all production and management stations and
systems can be used end-to-end.
By connecting an IWLAN access point to the Ethernet network,
the latter is expanded by radio functionality. The connection
of stations by radio is via their integral WLAN interface, e.g. for
a laptop, or via an IWLAN client module to which a station or
a further network segment can be connected by cable.
Existing controllers and processes can be accessed without
incurring excessive additional cabling costs.
Stations linked by radio can move freely within the range of
the Industrial Wireless LAN by using a radio link and the
roaming function.

Mobile controls in an automated guided vehicle system
Our industrialized products for wireless communication are
characterized by reliability, ruggedness, suitability to harsh
industrial environments, and security.
Radio infrastructure
Instead of copper cables and fiber-optic cables, wireless transmission techniques use radio waves. The propagation characteristics of the electromagnetic waves can differ considerably
and depend on the surrounding environment and the installed wireless infrastructure.
SCALANCE W modules use techniques such as antenna
switchover or diversity, high-quality receivers and fault-tolerant modulation procedures to enhance signal quality and to
prevent interruption of radio communication. Extensions to
the IEEE 802.11 standard also permit reliable, wireless transmission from PROFINET, form the basis for wireless safety
applications and the transmission of video data with extremely short reply and update data.

Ruggedness and industrial capability
Reliability of data communication
The SCALANCE W products can be exposed to fluctuations in
the extended temperature range, or continuous contact with
dust and water. Rugged enclosure and construction-based
protection against shock and vibration allow use in harsh
ambient conditions.
Accessories such as antennas, power supplies and cables are
also part of this concept and manufactured in line with industrial requirements.
The international standard IEEE 802.11n makes wireless communication via IWLAN even more robust. The greatest advantage results from the use of multiple path propagation (Multiple Input, Multiple Output (MIMO)). This allows the devices
parallel use of multiple antennas. A higher data transfer rate
is thus achieved and fault susceptibility in environments with
a high number of reflections is reduced.
Power and data are transferred over one cable with Powerover-Ethernet, thus saving investment and maintenance
costs.
SCALANCE W products with IWLAN in accordance with
IEEE 802.11n support up to three "streams" in the send and
receive directions.
The swap medium C-PLUG (Configuration Plug) saves engineering and configuration data, making device replacement
possible in a short time and without specially trained personnel. This minimizes standstill times and saves training costs.

IWLAN from Siemens
Powerful, rugged, and secure
Thanks to the use of mobile devices linked via wireless data
networks (e.g. wireless LAN), the efficiency of processes can
be significantly 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 competitiveness, 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.
Industrial Wireless LAN (IWLAN) is based on the WLAN standard IEEE 802.11 and provides extensions that are particularly
suited to demanding industrial applications with real-time and
redundancy requirements. Customers are thus provided with
a single wireless network for both process-critical data and
uncritical communication.
SCALANCE W products are characterized by the reliability of
their radio channel and the rugged type of construction with
high requirements with respect to mechanical durability for
which SIMATIC is known. To protect against unauthorized
access, the products provide modern standard mechanisms
for user identification (authentication) and encryption of
data, and can at the same time be easily integrated into
existing security concepts. These are based on international
standards in accordance with IEEE 802.11 at 2.4 GHz and
5 GHz, and data transfer rates of up to 450 Mbit/s.

Benefits
• The number of nutrunners used in vehicle final assembly
should be reduced. The existing solution uses one nutrunner for each cycle and each barcode detection
• Since the hard-wired solution with slip rings results in high
maintenance costs, a reliable wireless communication
solution is required to increase efficiency and reduce setup
times
• The products should be industrialized and available
worldwide
• Investment protection is also required by ensuring the
long-term availability of the components used
• Low investment costs owing to the reduced number of
nutrunners
• Reduction in maintenance costs and downtimes thanks to
a reliable wireless and wear-free data transfer to mobile
communication partners
• Increased plant availability thanks to reliable, contactless
transmission of power and data
• Reduction of operator activity, for example scanning, cycle
transfer, travel time allows higher throughput
• Easy to change models, dependent only on material
logistics
• Possibility of integrating additional quality assurance
applications
• Complete nutrunner data can be loaded via the IWLAN line
Solution
• The IWLAN RCoax Cable − a silicon-free radiating cable −
is used along the coding rail to enable wireless data transfer. 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.
• IWLAN access points with data transfer rates up to
54 Mbit/s are used as the supply station for the RCoax
cable.
• By using the client module as a mobile station, the same
mobile unit can be used for all applications, and consequently one mobile nutrunner can be employed for
multiple cycles.

SCALANCE W access points are used to operate 54 automated guided vehicles (AGV), guaranteeing optimum
coverage of the radio area involved.
• 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.
Benefits
• Interference-free operation thanks to the excellent functioning of the radio network.
• Savings in costs, as the existing infrastructure (masts and
antennas) could be retained
• Easy operation and configuration of all access points

Industry-standard products for wireless communication
IWLAN controller and controller access points
Fundamental principles of the controller-based Industrial
Wireless LAN
The IWLAN controller enables centralized management of an
Industrial Wireless LAN. It automatically detects new access
points, establishes a connection to them, and manages and
coordinates access points and clients. This function allows
wireless expansion of an Ethernet network without having to
make changes to the existing network topology.
The IWLAN controller connects, manages and coordinates all
access point and clients such that the WLAN environment
appears like several IP subnetworks with central management. The individual connections are additionally managed
here, and the stations can therefore move securely and reliably throughout the entire radio network.
With the IWLAN controller, the IWLAN wireless infrastructure
can be divided into logical, service-based networks (Virtual
Network Services). Different services, security requirements
and access criteria can thus be reliably managed, and different
user groups such as administrators, commissioning engineers, or visitors can use the same wireless network.
For optimum capacity utilization of the IWLAN network, different applications such as Voice-over-IP (VoIP), video, and Internet access can use the same infrastructure.
Diagnostics and management functions
As well as centralized management and wireless network configuration, the WLC711 IWLAN controller also offers error
recording, wireless network monitoring, and documentation
of network statistics.

Industry-standard products for wireless communication
Antennas with multiple connections
(dual or MIMO antennas)
Antennas with two connections combine two individual antennas, at 90° to each other, in a single antenna enclosure.
With these antennas, two data streams can be transferred simultaneously thanks to the two different polarization levels.
Depending on the alignment of the polarization levels, these
antennas are referred to as dual-slant (rotated through +/-45°)
or vertical-horizontal.
Antennas with three connections contain three individual
emitters that can be combined in a single enclosure, either on
different polarization levels (0°, +/-45°) or at a suitable distance from each other. The so-called MIMO antennas can
transmit three data streams simultaneously using multiple
path propagation. Transmission of several data streams results
in increased data throughput with simultaneously achieving
more reliable data transfer.

Structure of RCoax cable
Openings are present in the outer conductor of the coaxial
cable which permit the penetration and emission of radio
waves. This permits development of a defined radio field
around the RCoax cables. Longitudinal damping and extraction loss are in a balanced relationship, which permits a long
segment length of cable per SCALANCE W780 Access Point
and an appropriate distance from the mobile station
(SCALANCE W740, IWLAN/PB Link PN IO) to the RCoax cable.

System solution with IWLAN/PB Link PN IO using example of suspended monorails
The IWLAN/PB Link PN IO is a compact router between Industrial Wireless LAN (IWLAN) and PROFIBUS, and allows wireless
connection to an IWLAN (e.g. SCALANCE W access points) in
accordance with IEEE 802.11 at up to 54 Mbit/s with 2.4 GHz
and 5 GHz.
It supports the use of an IWLAN, for example with RCoax
radiating cables, for wireless data transmission in the case of
suspended monorails, storage and retrieval systems, or other
applications with mobile stations. Support of PROFINET
means that the wide variety of PROFIBUS system services,
such as diagnostics over the bus, can still be utilized.
The IWLAN/PB Link PN IO offers:
• High, deterministic data throughput and very fast roaming
through support of iPCF; the iPCF mechanism represents an
extension of the IEEE 802.11 standard and must be available both on the station and on the access point.
• PROFINET IO proxy functionality
Connection of PROFIBUS DP slaves to PROFINET IO controller according to PROFINET standard:
