cifX with 2 Communication Status LEDs
(AIFX-DP is connected or for prior Hardware Revisions)
LED green
(green)
On
Communication to all Slaves is established.
(green)
Flashing (5 Hz)
PROFIBUS is configured, but bus communication is not yet released
from the application.
(green)
Flashing acyclic
No configuration or faulty configuration
STA
(off)
Off
LED red is off:
Device is not switched on or network power is missing.
LED red is flashing or “on”:
Refer to description LED red.
LED red
(off)
Off
Refer to description for LED green.
(red)
Flashing (5 Hz)
Communication to at least one Slave is disconnected.
ERR
(off)
On
Communication to all Slaves is disconnected or another serious error
has occurred.
Redundant Mode: The active Master was not found.

LED State
Definition
Flashing (5 Hz)
The indicator turns on and off with a frequency of 5 Hz:
"on" for 100 ms, followed by "off" for 100 ms.
Flashing
acyclic
The indicator turns on and off in irregular intervals.
