1.7.2 Slave Display for AS-i Slaves
Interpreting the slave display status
The slave display can be recognized by the fact that at least
one group LED is lit green and that the ADR LED is not red.
The lower 5 LEDs then indicate the slaves on the
AS-Interface. In this case, the label to the left of the LEDs
applies. The display always represents 5 slaves.
Display Statuses and Operation in Detail
The AS-i slaves are displayed in groups of five. The upper three group LEDs
indicate (in green) which of the groups of 5 is displayed. The following distinction is
also made:
S
Static display: AS-i standard slaves and A slaves
S
Flashing display: B slaves
The lower five LEDs are lit green to indicate the detected or active AS-i slaves
within the group.
You can move from group to group by pressing the DISPLAY button again.
The module returns to the status display in the following situations:
S
After displaying the last group (AS-i slaves 30, 31) and pressing the DISPLAY
button twice. (In other words changing to the PROFIBUS address display and
then to the status display.)

If you do not press the DISPLAY button for approximately 8 minutes.
