EtherCAT signalling LEDs
The EtherCAT variant of the Pluto has 3 LEDs to indicate the board status.
EtherCAT status LED
The EtherCAT Plug-in Board has a bicolor / LED. The Green LED is the , and the Red GREEN RED RUN LED
LED is the .ERROR LED
Next table shows the EtherCAT LEDs truth table, which indicates the status of the EtherCAT state machine.
RUN LED Slave State ERROR LED Slave State
Off INIT Off No error
Blinking PRE-OPERATIONAL Blinking Invalid configuration
Single Flash SAFE-OPERATIONAL Single flash Local error
On OPERATIONAL Double flash Watchdog timeout

The frequency of the blinking is different than the used for communication and is product
dependant.
EtherCAT in-connector LED
