KEY-PLUG W700

■

Overview

• Swap medium with which iFeatures are enabled

• If a fault occurs, it allows fast and simple device replacement

of SCALANCE W components without a PG

• Can be used in all SCALANCE W700 IEEE 802.11n products

with a PLUG compartment

• For the automatic backup of configuration data

■

Benefits

• Fast and simple replacement of SCALANCE W components

without reconfiguration of the spare part.

• The device can be replaced without the need for specially

trained personnel or a programming device or PC.

• The downtimes of network segments and connected Industrial

Ethernet nodes can therefore be minimized if a fault occurs.

■

Application

The KEY-PLUG stores the configuration data of a SCALANCE W

component. In addition, the iFeatures are enabled.

In addition to this, if there is a fault on a module, the module can

be replaced simply and quickly without needing to reconfigure

the replacement device and without specially trained personnel.

If a device needs to be replaced, the KEY-PLUG is simply re-

moved from the failed component and plugged into the replace-

ment device. The replacement device installed in the network

now starts up automatically with the same device configuration

as the failed device.

■

Design

The KEY-PLUG has degree of protection IP20. The degree of

protection of IP65 components is ensured by the design of the

target device. The KEY-PLUG is inserted in the PLUG compart-

ment of the SCALANCE W component.

■

Mode of operation

During startup, the device automatically backs up the configura-

tion data on a KEY-PLUG (as-supplied from the factory) plugged

into a SCALANCE W component. Changes to the configuration

during operation are also saved on the KEY-PLUG without any

additional operator intervention being necessary.

During startup, an unconfigured device automatically loads the

configuration data from an inserted KEY-PLUG that has been

written to provided the data was written by a compatible device

type.

Diagnostics

Incorrect use of the KEY-PLUG, such as inserting a KEY-PLUG

containing the configuration of a different device group or

general malfunctions of the KEY-PLUG are indicated by

diagnostics mechanisms of the host device (LEDs, SNMP,

Web based Management, etc.).
