PROFINET IO-Device
For the
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).

Flashing
(1 Hz, 3 s)
The LED 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 LED turns on and off with a frequency of
2 Hz: “On” for 250 ms, followed by “Off” for 250 ms.

LED state
Definition
Flickering
(load
dependent)
The LED 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 LED turns on and off in irregular intervals to indicate low
Ethernet activity.
