SFA-5000 • SFA-10000 EtherCAT
4.6 Diagnostic LEDs
Five LEDs located in the rear side of the connection cap are designed to show
the operating or fault status of the EtherCAT® interface.
The LEDs operation is according to the EtherCAT specifications, see
ETG1300_S_R_V1i1i0_IndicatorLabelingSpecification.pdf.
LED states
Definition
ON
The indicator shall be constantly ON.
OFF
The indicator shall be constantly OFF.
Flickering
The indicator shall turn ON and OFF iso-phase with a frequency
of 10 Hz: ON for 50 ms and OFF for 50 ms.
Blinking
The indicator shall turn ON and OFF iso-phase with a frequency
of 2.5 Hz: ON for 200 ms followed by OFF for 200 ms.
Single flash
The indicator shall show one short flash (200 ms) followed by a
long OFF phase (1000 ms).
Double flash
The indicator shall show a sequence of two short flashes (200
ms), separated by an OFF phase (200 ms), and followed by a
long OFF phase (1000 ms).
