LED “(Bus) State“
Indicator states and flash rates
The following Indicator states are distinguished:
LED on
constantly on
LED off
constantly off
LED flickering
iso-phase on and off with a frequency of approximately 10 Hz: on for approxi-
mately 50 ms and off for approximately 50 ms.
LED blinking
iso-phase on and off with a frequency of approximately 2,5 Hz: on for approxi-
mately 200 ms followed by off for approximately 200 ms.
LED single flash
one short flash (approximately 200ms) followed by a long off phase (approxi-
mately 1000 ms).
LED double flash a sequence of two short flashes (approximately 200ms), separated by an off
phase (approximately 200ms). The sequence is finished by a long off phase
(approximately 1000 ms).
LED triple flash
a sequence of three short flashes (approximately 200ms), separated by an off
phase (approximately 200ms). The sequence is finished by a long off phase
(approximately 1000 ms).
If one bicolor Status LED is used instead of two single color LEDs, this LED shall indicate both
the physical bus status and the status of the CANopen
®
state machine. This bicolor LED shall be
red and green.
CANopen
®
ERROR LED (red)
The CANopen
®
Error LED indicates the status of the CAN physical layer and indicates errors due
to missing CAN messages (SYNC, GUARD or HEARTBEAT).
ERROR LED
State
Description
Off
No error
The Device is in working condition.
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).
Flickering
AutoBaud/LSS
Auto Baudrate detection in progress or LSS services in
progress (alternately flickering with RUN LED).
Double flash
Error Control Event
A guard event (NMT-Slave or NMT-master) or a heartbeat event
(Heartbeat consumer) has occurred.
Triple flash
Sync Error
The SYNC message has not been received within the configured
communication cycle period time out (see Object Dictionary Entry
0x1006).
On
Bus Off
The CAN controller is’bus off
If at a given time several errors are present, the error with the highest number is indicated (e.g. if
NMT Error and Sync Error occur, the SYNC error is indicated)
.
CANopen
®
RUN LED (green)
The CANopen
®
RUN LED indiates the status of the CANopen
®
network state machine.
CAN RUN LED State
Description
Flickering
AutoBaud/LSS
Auto Baudrate detection in progress or LSS services in progress
(alternately flickering with RUN LED).
Single flash
STOPPED
The device is in STOPPED state.
