SCALANCE X108 Button 

What does the button do? 

Using the button, you can display and modify the set fault mask.  
After pressing the button, the currently valid fault mask is displayed for approximately 3 

seconds. The LEDs of the monitored ports flash at a frequency of 5 Hz. 
After 3 seconds the new fault mask is displayed. The flashing frequency is reduced to 2.5 

Hz. After a further 3 seconds, the new fault mask is adopted and saved. The monitored ports 

are indicated by permanently lit LEDs until the button is released. 
As long as the LEDs are still flashing, the saving of the mask can be interrupted by releasing 

the button. 
If an empty fault mask is set (no port is monitored) or you want to set an empty mask, four 4 

LEDs flash on and off alternating with their neighboring LEDs. 
At the same time, you can also set the monitoring of the redundant power supply with the 

fault mask. Monitoring of the power supply is activated only when both power supplies are 

connected when the fault mask is saved. 
The factory default is no port monitoring.
