3.1 LED Self-Test Sequence and Functions
The EtherCAT F/T provides (3) LEDs for EtherCAT Link, Run, and
Sensor Status. When the user applies power, the sensor completes
a self-test, during which the LEDs under firmware control individu-
ally turn on.
3.1.1 LED Self-Test Sequence
When the user applies power to the sensor, the sensor completes
a self-test, during which the LEDs under firmware control individu-
ally turn on in the following sequence:
Sequence
Order
LED
State
Duration
1
Sensor Status
Red
Approximately one
second for each
LED.
2
Run
Red
3
EtherCAT Link/Activity Red
4
Sensor Status
Green
5
EtherCAT Link/Activity Green
The Green Run LED is not tested in the self-test sequence.
3.1.2 EtherCAT Link/Activity LED
One LED signals link/activity on the EtherCAT port as follows:
LED State
Link
Activity
Condition
Off
No
No
No Ethernet connection
Green
Yes
No
Ethernet link/activity is
detected.
Yes
1
1
This LED behavior is different from the standard EtherCAT device
Link/Activity LED behavior, which is a flashing green LED.
3.1.3 Run LED
One LED signals the communication status of the EtherCAT sensor
interface as follows:
LED State
Description
Off
EtherCAT interface is in the state “INIT”.
Flashing green EtherCAT interface is in the state “Preoperational”.
Green
EtherCAT interface is in the state “Operational”.
