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
rapidly

State of the EtherCAT State Machine: 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.
Outputs remain in safe state

on

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