6.7.2 SELECT / SET Button
The SELECT / SET button is used to switch over the display modes (DMode). After
turning on the SCALANCE X414-3E, it is in DMode A.
The button has the following functions:
● Changing the display modes
By pressing the button briefly, you change from one display mode to the next.
The selected mode or current status is displayed by the LEDs (DM1, DM2).
● Resetting to the factory defaults
It is possible to restore some of the factory default settings in DMode A by
pressing the button for 12 seconds. You can cancel the reset procedure by re-
leasing the button before the 12 seconds have elapsed. All previously made
settings are overwritten by the factory defaults.
● Defining the fault mask and the LED displays
It is possible to set the fault mask in DMode A and DMode D. This allows you to
specify the mask for signaling faults by defining an individual "good status“ for
the connected ports and the power supplies. In this case, you press the button
for 5 seconds in DMode A or DMode D. After 3 seconds, the two LEDs (DM1
and DM2) start to flash. You can cancel the procedure by releasing the button
before the 5 seconds have elapsed. If, however, you press the button for a fur-
ther 2 seconds, the current states of all ports and the states of the power sup-
plies L1 and L2 are included in the fault mask. The previous fault mask is then
overwritten.
