LEDs and connection 3:Fig.5: 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.
Outputs remain in safe state

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.
