Warning limit reached:
At least one of the error counters of the CAN
controller has reached or exceeded the warning level (too many error
frames).
(red)
Double flash
Error control event:
A guard event (NMT Slave or NMT Master) or a
heartbeat event (Heartbeat consumer) has occurred.

LED state
Definition
Flickering
(10 Hz)
The LED turns on and off with a frequency of 10 Hz: “On” for 50 ms,
followed by “Off” for 50 ms.
Blinking
(2.5 Hz)
The LED turns on and off with a frequency of 2.5 Hz: “On” for 200 ms,
followed by “Off” for 200 ms.
Single flash
The LED shows one short flash (200 ms) followed by a long “Off“ phase
(1,000 ms).
Double flash
The LED shows a sequence of two short flashes (each 200 ms),
separated by a short "Off" phase (200 ms). The sequence is finished by a
long "Off" phase (1,000 ms). The LED turns on and off in irregular
intervals to indicate low Ethernet activity.
