EL6731 - LED description

LED behavior

The LEDs facilitate diagnosing of the main terminal states:

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; BOOTSTRAP = function for firmware updates of the terminal
		single flash	State of the EtherCAT State Machine: PREOP = function for mailbox communication and different standard-settings set
		Flashing	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
BF	red	off	DP master is in CLEAR/OPERATE mode, all DP slaves are in data exchange
		Flashing	DP master is in CLEAR/OPERATE mode, at least one DP slave is in data exchange
		on	DP master is in STOP mode
CPU Err	red	on	EL6731 processor error
CPU Err	red	single flash	The EL6731 processor starts
