Industrial Wireless Communication

IWLAN – Client Modules IEEE 802.11n

Overview

iFeatures (only in conjunction with KEY-PLUG or

SCALANCE W722-1 RJ45))

iPCF (industrial Point Coordination Function):

The iPCF mode is a good choice for applications with require-

ments for real-time and predictable response times (determinis-

tic response), even when mobile nodes are roaming from

one access point to the next. This ensures that wireless

PROFINET IO is supported and that safety-related signals,

e.g. emergency stop, can be linked into the RF field.

The iPCF mechanism expands the IEEE 802.11 standard and

must be available on both the client module and the access

point. In an RF field in which iPCF is used, no IEEE 802.11-com-

pliant nodes can be operated.

iPCF is recommended for applications where wireless network

nodes move along predefined paths (e.g. suspended monorail).

RCoax radiating cables or directional antennas must be used for

this purpose.

Linking in an automated guided vehicle system using iPCF with the SCALANCE W722-1 RJ45

iPCF-MC (iPCF Management Channel)

iPCF-MC is available as a further development of iPCF.

This mode should be used if IWLAN stations that also support

iPCF-MC move freely about in the coverage area (especially

when using omni-directional antennas) and are to exchange

data deterministically. This functionality can only be achieved in

connection with access points with two wireless interfaces and

the KEY PLUG.

Note:

These iFeatures cannot be used in parallel.

Diagnostics and management

• Web-based (HTTP/HTTPS) management tool for configuration

and diagnostics using a standard browser

• LEDs for signaling operating status and fault/error states

• Signaling of faults by means of SNMP trap or e-mail to a

network management tool

• 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.
