RUN |
green |
This LED indicates the terminal's operating state: | |
|
off |
State of the EtherCAT State Machine: INIT = initialization of the terminal | ||
|
flashing uniformly |
State of the EtherCAT State Machine: PREOP = function for mailbox communication and different standard-settings set | ||
|
flashing slowly |
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 | ||
|
flashing rapidly |
State of the EtherCAT State Machine: BOOTSTRAP = function for terminal firmware updates | ||
