IWLAN – the WLAN for challenging industrial applications

Industrial wireless communication – a key element in the digital transformation

The advances being made in the digitalization of industry would be inconceivable without state-of-the-art communications technology. To provide businesses with the best possible infrastructure for exchanging data of all kinds, Siemens has developed dedicated Industrial Wireless LAN (IWLAN) products with special additional functions to meet the specific demands of WLAN in industry. These are particularly useful for applications in automation, for example in automotive manufacturing, transportation and logistics, and the oil and gas industry.

Easy, compact solutions

WLAN from the control cabinet

Implement wireless networking of machines easily and economically – with SCALANCE W760 Access Points and SCALANCE W720 Client Modules! Due to their practical SIMATIC design, minimum space is required in the control cabinet when integrating automation components such as a SIMATIC ET 200SP seamlessly into an industrial WLAN, in accordance with the IEEE 802.11n standard and with data rates of up to 150 Mbps.

Demanding solutions

Wireless both inside and outside the control cabinet

Transfer data wirelessly from the control cabinet, or you can even use our devices with IP65 protection class outside the control cabinet. The SCALANCE W770 Access Points and SCALANCE W730 Client Modules in SIMATIC design reliably and flexibly implement wireless communication between the controller and an I/O system like the SIMATIC ET 200MP.

High-performance solutions

WLAN for indoors, outdoors, and in harsh environments

Using wireless communication where high-end, powerful and reliable data transmission is required: The SCALANCE W780 Access Points and SCALANCE W740 Client Modules support data rates of up to 450 Mbps in accordance with standard IEEE 802.11n. Devices with IP30 protection class are suitable for use in the control cabinet, whereas IP65 devices are perfect for use outside the control cabinet and outdoors under harsh environmental conditions. In combination with the iFeatures functionalities, a whole host of additional applications is enabled, such as real-time or redundant communication.

With the latest WLAN standard IEEE 802.11ac Wave 2, SCALANCE W1780 Access Points and SCALANCE W1740 Client Modules enable applications to be implemented in harsh industrial environments that need particularly large bandwidths, e.g. for high-performance video transmission.

Moderate environments

High-performance WLAN in moderate environments

The SCALANCE W1750D controller-based Direct Access Points support radio transmission according to the latest WLAN standard IEEE 802.11ac Wave 2. This new technology offers very high data transmission rates as required, for example, for video streaming. The high-performance SCALANCE W1750D, which are available in different country-specific versions, manage wireless networks with up to 128 Access Points. Typical areas of application include moderate ambient conditions such as those in assembly halls and adjoining offices or open warehouses. Due to their attractive design, the Direct Access Points can also be installed in cafeterias and conference rooms.

Antennas and accessories

Antennas for every application

A broad antenna portfolio rounds off the comprehensive IWLAN solutions from Siemens. These include omnidirectional antennas for a large-area radio field in all directions, directional antennas for a wireless field aligned in a specified direction, and sector or wide-angle antennas for a large radio field. In addition to many types of antenna, we also offer cabling technology as well as mounting accessories such as cables, lightning conductors and plug-in connectors.

As a special antenna solution for SCALANCE W components, the RCoax radiating cables ensure reliable wireless connections along defined radio links. The coaxial cable, with its special radiating characteristics, is rugged and easy to install, and is suitable for use in areas susceptible to explosions (Zone 2), without special approvals. It is connected to SCALANCE W Access Points as an external antenna.

Smart additional functions

iFeatures expand opportunities in industry applications of all kinds

Wireless communication via Industrial Wireless LAN (IWLAN) is already used in countless solutions, e.g. by mobile network participants in Automatic Guided Vehicles (AGV) or in crane applications. Not only the hardware, but also the software of the network components must meet special requirements for use in the industry.

Siemens has developed special iFeatures for use in industrial environments which are enabled by KEY-PLUGs or CLPs inserted into the devices. These smart additional functions can be easily activated as software – also subsequently – on various IWLAN Access Points and Client Modules. These additional functions are suitable for all industries and all kinds of application. The following typical examples of application offer more detailed information. 

IWLAN for transportation systems

Increased availability and the potential for interference demand redundant solutions via WLAN. Thanks to Industrial Parallel Redundancy Protocol (iPRP), our IWLAN solutions in the transportation area ensure redundant and thus reliable communication.

IWLAN in logistics

The logistics sector involves many time-critical applications with participants moving freely in the field that have to communicate wirelessly with a controller. The Industrial Point Coordination Function with Management Channel (iPCF-MC) ensures that our solutions meet real-time communication requirements.

Benefits of IWLAN

Unlimited communication

Requirements on industrial networks are constantly increasing in the course of digitalization. Particularly when dealing with wireless data transmission, the network components are subject to very specific requirements: our IWLAN solutions guarantee maximum reliability and performance.

Many applications, exact solutions

No matter which industry or which application you need, our wireless communication components cover a wide range of applications for both indoor and outdoor use. They are uniquely suited to industrial applications, even under the harshest conditions. The open Industrial Ethernet standard PROFINET or Ethernet/IP as well as PROFIsafe via WLAN also ensure increased efficiency, flexibility and safety.  

Effective Industrial Wireless LAN diagnostics with SCALANCE W

Reliable wireless communication connections without interruptions are possible due to three integrated diagnostics tools: Spectrum Analyzer, Signal Recorder and Remote Capture.

Discover the benefits and find out about the many possibilities for creating your individual network solution with IWLAN.

Cable-free connections

Wireless connections are ideal for applications where it would be too complex or even impossible to lay cables. Using our SCALANCE W portfolio, you benefit from total flexibility and fail-safe communications at all times, even without a wired connection.

Secured communication

While data security is an increasingly important element in communications, personal safety is also absolutely essential in production processes and in applications involving passenger transport. Security and integrity of all data is provided by the currently applicable protocols (e.g. IEEE 802.1X) and encryption. You can use PROFINET with PROFIsafe to implement safety applications with an emergency stop function via WLAN to assure the necessary safety for employees in production or passengers in transport applications.

Precision timing of data transmission

Moving data packets quickly from point A to point B is a must for many communication applications. SCALANCE W devices and iFeatures make easy work of real-time communication using PROFINET and EtherNet/IP.

Reliable communication

To ensure data arrives not only quickly but also reliably, redundant communication is essential – that way no information is lost. Various diagnostic options incorporated in the SCALANCE W products also provide the option of rapidly identifying and fixing the problem if a fault occurs.

Robust and flexible

SCALANCE W devices with IP65 protection class are suitable for use outside the control cabinet, e.g. in production halls, and outdoors under harsh environmental conditions. Various approvals for traction applications and also areas susceptible to explosion are available for our devices that are used in enhanced environmental conditions (EEC).
