EL2574 - LEDs
LED | Color | Meaning | |
|---|---|---|---|
RUN | green | This LED indicates the terminal's operating state: | |
off | State of the EtherCAT State Machine: INIT = initialization of the terminal | ||
flashing | State of the EtherCAT State Machine: PREOP = function for mailbox communication and different default 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 | ||
flickering | State of the EtherCAT State Machine: BOOTSTRAP = function for Firmware updates of the terminal | ||
Warning, Error | yellow | Warning | |
red | Error | ||
Power OK | green | The supply to the electronics is within the permissible range. | |
Output 1 … 4 | green | The LED output is active. | |
