SELECT/SET button
Function of the SELECT/SET button
With the SELECT/SET button, you can change various settings of the device. Modified settings are
retained after device power off/on.
The SELECT/SET button is used to switch over the display mode and to make other settings. After
turning on the SCALANCE X-200RNA, it is in the display mode.
The SELECT/SET button has three functions:
• Triggering a device restart
• Reset to the factory defaults All settings made are overwritten by the factory defaults.
• Define the fault mask and the display at the LEDs. The current states of all ports and the states
of the power supplies L1 and L2 are included in the "X200 Fault Mask Power" dialog box. The
previous fault mask is then overwritten.
Different settings are made depending on how long you hold down the SELECT/SET button:
