Option LED Display
The EtherCAT Option has four LED displays that indicate the communication status. The indications conform with
DS303, Part 3: Indicator Specification.
L/A IN, L/A OUT
The Link/Activity indicators show the status of the physical link and show activity on the link period
RUN
A green lit EtherCAT RUN LED indicates the status of the EtherCAT network state machine.
A red lit EtherCAT RUN LED is only used by the NOID firmware loader (refer to
Table 4
).
ERR
The red EtherCAT error LED indicates the presence of any errors.

Status
L/A IN
L/A OUT
–
Continuously off
No link. The communication cable is not physically connected or the EtherCAT
controller is not started up.
Green
Continuously on
The option is connected to Ethernet. A communication cable is physically connected,
but data is not being exchanged.
Flickering
There is traffic on Ethernet. Data is being exchanged.
RUN
–
Continuously off
The device is in INIT state.
Green
Blinking
The device is in Pre-Operational state (flashing rate about 400 ms).
Single flash
The device is in Safe-Operational state.
Single flash is one short flash (approximately 200 ms), followed by a long off phase
(approximately 1000 ms).
Continuously on
The device is in Operational state.
Red
Blinking (1 Hz or 6 Hz)
The Option BOOT or APP firmware is executing the NOID firmware loader.
1 Hz: Firmware loader protocol is in IDLE state (waiting for commands from the
drive).
6 Hz: Firmware loader protocol is processing commands.
ERR
Red
Continuously off
No fault. The EtherCAT communication is operating normally.
Blinking
General configuration error
Single flash
The slave device application has changed the EtherCAT state autonomously.
The parameter “Change” in the AL status register is set to 0x01: change/error.
Single flash is one short flash (approximately 200 ms), followed by a long off phase
(approximately 1000 ms).
Double flash
The sync manager watchdog time out has occurred.
Double flash is two short flashes (approximately 200 ms each), separated by an off
condition (approximately 200 ms), and then a long off phase (approximately 1000 ms).
Continuously on
Possible causes:
• An EtherCAT PDI (Process Data Interface) error has occurred or the NOID
application interface has failed.
• An option card FATAL event has occurred (System has stalled execution; see
manufacturer specific profile object 0x4000 for cause).
Blinking (1 Hz or 6 Hz)
The option BOOT or APP firmware is executing the NOID firmware loader.
1 Hz: Firmware loader protocol is in IDLE state (waiting for commands from drive).
6 Hz: Firmware loader protocol is processing commands.
