Industrial Wireless Communication

IWLAN – Client Modules IEEE 802.11n

Overview

■

Overview

The client modules from the SCALANCE W700 product lines are

optimal for integrating Industrial Ethernet stations into Industrial

Wireless LANs (IWLANs) for 2.4 GHz and 5 GHz.

• High data rates (up to 450 Mbit/s in connection with Channel

Bonding) as per IEEE802.11n

• Reliable wireless link by using of MIMO technology (Multiple

Input, Multiple Output). For this, SCALANCE W Client Modules

use up to three streams for simultaneous sending and

receiving.

• SCALANCE W700 Client Modules are suitable for any appli-

cation: for installation indoors without a control cabinet and for

installation in a control cabinet

• Reliable thanks to a rugged enclosure, protected from water

and dust (up to IP65), resistant to shock, vibration and electro-

magnetic fields

• Demanding applications with real-time and redundancy

requirements, such as PROFINET with PROFIsafe

• Conformant to standards through supporting IEEE802.11;

expanded software functions especially for use where

increased reliability is required, e.g. cyclic real-time data

traffic and very high-speed roaming (iPCF, iPCF-MC)

• Configuration support by means of wizards and online help;

easy management via Web server and SNMP

• Configuration and diagnostics using Web based

Management, Command Line Interface, and SNMP. Devices

and networks can be configured using STEP 7 (TIA Portal).

For cyclic monitoring, diagnostics and documentation

(reporting) in network mode, the SINEMA Server software is

recommended.

• Enabling of further functions using the KEY-PLUG swap

medium (iPCF, iPCF-MC)

• Fast replacement of devices if a fault occurs thanks to use of

optional KEY-PLUG/C-PLUG (Configuration Plug) swap

medium

Benefits

• Predictable data traffic (deterministic response) and defined

response times on the wireless link

• Reliable wireless link, e.g. by using MIMO technology and

monitoring the wireless link

• Cost savings due to one single wireless network both for

process-critical data and for non-critical communication

• Future-proof because all products are compatible with the

internationally recognized WLAN standard IEEE 802.11,

suitable for license-free 2.4 GHz and 5 GHz frequency bands

(ISM bands)

• Implementation of data-intensive applications such as video

streaming

• Reduced operating costs, because there is no wear and tear

on rotating and moving plant sections

• Cost-effective connection to devices which are remote,

difficult to access or installed in hostile environments

• Investment protection because flexible feature expansions

(iFeatures) are possible by using the KEY-PLUG
