LEDs

No. LED Color Meaning

1

RUN

green

This LED indicates the terminal's operating state:

off

State of the EtherCAT State Machine: INIT = Initialization of the terminal or BOOTSTRAP = Function for firmware updates of the terminal

blinking

State of the EtherCAT State Machine: PREOP = Setting for mailbox communication and variant standard settings

single flash

State of the EtherCAT State Machine: SAFEOP = Channel checking of the Sync Manager and the Distributed Clocks. Outputs stay in safe operation mode.

on

State of the EtherCAT State Machine: OP = Normal operation mode, mailbox- and process data communication possible
