Configuration
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 valid 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.
Information about the configuration of the C-PLUG / KEY-PLUG
This page provides detailed information about the configuration stored on the C-PLUG or
KEY-PLUG. It is also possible to reset the PLUG to "factory defaults" or to load it with new
contents.
Note
The action is only executed after you click the "Set Values" button.
The action cannot be undone.
If you decide against executing the function after making your selection, click the "Refresh"
button. As a result the data of this page is read from the device again and the selection is
canceled.
Note
Incompatibility with previous versions with PLUG inserted
During the installation of a previous version, the configuration data can be lost. In this case,
the device starts up with the factory settings after the firmware has been installed. In this
situation, if a PLUG is inserted in the device, following the restart, this has the status "Not
Accepted" since the PLUG still has the configuration data of the previous more up-to-date
firmware. This allows you to return to the previous, more up-to-date firmware without any
loss of configuration data.
If the original configuration on the PLUG is no longer required, the PLUG can be deleted or
rewritten manually using "System > PLUG".
