LEDs | |||
|---|---|---|---|
LED | Color | Meaning | |
RUN* | green | This LED indicates the terminal's operating state (if more than one RUN LED is present, all of them have the same function): | |
off | State of the EtherCAT State Machine: INIT = initialization of the terminal or BOOTSTRAP = function for firmware updates of the terminal | ||
flashing | State of the EtherCAT State Machine: PREOP = function for mailbox communication and different standard-settings set | ||
single flash | State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks. | ||
on | State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible | ||
*) If several RUN LEDs are present, all of them have the same function | |||
