PLUG
The PLUG is available in the following variants:
•
C-PLUG: The removable data storage medium only saves the configuration data of
the device.
•
KEY-PLUG: In addition to the configuration data, the removable data storage medium
contains a license with which special functions are enabled, e.g. iFeatures.
You will find the article numbers under Accessories (Page 22).
NOTICE
Do not remove or insert a C-PLUG / KEY-PLUG during operation!
A PLUG may only be removed or inserted when the device is turned off.
The device checks whether or not a PLUG is inserted at one second intervals. If it is
detected that the PLUG was removed, there is a restart.
If a KEY-PLUG was inserted in the device, the device changes to a defined error state
following the restart. With SCALANCE W, the available wireless interfaces are
deactivated in this case.
If the device was configured at some time with a PLUG, the device can no longer be
used without this PLUG. To be able to use the device again, reset the device to the
factory settings.
