These LEDs indicate the terminal's operating state:

off

State of the EtherCAT State Machine: INIT = initialization of the terminal

Flashing
(2 Hz)

State of the EtherCAT State Machine: PREOP = function for mailbox communication and different default settings set

Flashing
(1 Hz)

State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks.
Outputs remain in safe state

on

State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible

Flashing
(10 Hz)

State of the EtherCAT State Machine: BOOTSTRAP = function for Firmware updates of the terminal, for example

Terminal point
