Meaning of the LEDs

8.4.4.1

Function of the LEDs

There are 4 LEDs on the front panel of the CU310-2 DP housing (see CU310-2 DP interface
overview (Page 252).)

The various LEDs are switched on and off as the control unit is powered up (depending on
the phase the system is currently in). When switched on, the color of the LEDs shows the
status of the corresponding power-up phase (see LED display during power up (Page 271))
In the event of a fault, power up will be ended in the corresponding phase. The LEDs that
are switched on retain their color at this particular instant in time, so that the fault can be
determined based on the combination of LEDs that are switched on (bright) and switched off
(dark).
All the LEDs go out briefly if the CU310-2 DP has powered up without error. The system is
ready for operation when the LED "RDY" is permanently green.
All the LEDs are controlled by the software loaded during operation (see Behavior of the
LEDs in the operating state (Page 272)).
