On
OPERATIONAL:
The device is in the OPERATIONAL state.
(green)
Blinking
(2.5 Hz)
PREOPERATIONAL:
The device is in the PREOPERATIONAL state.
(green)
Single flash
STOPPED:
The device is in STOPPED state.

alternatively
with ERR LED)
Auto Baud Rate Detection active:
The Device is in the auto baud rate
detection mode.
RUN
(off)
Off
LED red is off:
RESET:
The device is executing a reset or the device
has no configuration.
LED red is flickering, flashes or “on”:
Refer to description LED red.

(red)
Single flash
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.
ERR
(red)
On
Bus Off
: The CAN controller is in bus OFF state.

LED State
Definition
Flickering
(10 Hz)
The indicator 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 indicator turns on and off with a frequency of 2,5 Hz: “on” for 200 ms, followed by “off” for
200 ms.
Single Flash
The indicator shows one short flash (200 ms) followed by a long “off” phase (1,000 ms).
Double Flash
The indicator 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).
