KEY-PLUG W700
6
■
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.).
