8.15 PROFINET IO-Device
For the PROFINET IO-Device protocol, the communication LEDs
SF
(System Failure) and
BF
(Bus Failure) as well as the Ethernet LEDs
LINK
and
RX/TX
can assume the states described below. This description is
valid from stack version V3.x (V3).

Failure)
General
name:
COM 0
(red)
On
Watchdog timeout; channel, generic or extended diagnosis present;
system error
Duo LED red/green
(off)
Off No
error
(red)
Flashing
(2 Hz)
No data exchange
BF
(Bus
Failure)
General
name:
COM 1
(red)
On
No configuration; or low speed physical link;
or no physical link
LED green
(green)
On
The device is linked to the Ethernet.
LINK
Ch0 & Ch1
(off)
Off
The device has no link to the Ethernet.
LED yellow
(gelb)
Flickering
(load de-
pendant)
The device sends/receives Ethernet frames.
RX/TX
Ch0 & Ch1
(off)
Off
The device does not send/receive Ethernet frames.

LED state
Definition
Flashing
(1 Hz, 3 s)
The indicator turns on and off for 3 seconds with a frequency of 1 Hz: “on” for 500 ms, followed
by “off” for 500 ms.
Flashing (2 Hz)
The indicator turns on and off with a frequency of 2 Hz:
“on” for 250 ms, followed by “off” for 250 ms.
Flickering
(load
dependant)
The indicator turns on and off with a frequency of approximately 10 Hz to indicate high Ethernet
activity: on for approximately 50 ms, followed by off for 50 ms. The indicator turns on and off in
irregular intervals to indicate low Ethernet activity.
