LEDs for EtherCAT diagnosis

LED		Display	Description
RUN	green	off	State of the EtherCAT State Machine: INIT = initialization of the terminal; BOOTSTRAP = function for firmware updates of the terminal
		flashing 200 ms	State of the EtherCAT State Machine: PREOP = function for mailbox communication and different standard-settings set
		off (1 s) on (200 ms)	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

LED diagnosis PROFINET RUN/Err

Color green	Color red	Meaning
off	flashing 200 ms	Terminal starts
flashing 200 ms	off	No name
1 s off, 200 ms on	off	No IP address
on	off	EL terminal is parameterized

LED diagnosis PROFINET Err

Colours green	Colours red	Meaning
off	flashing 500 ms	no AR established with any device
off	1 s off, 200 ms on	At least one device has not established an AR
1 s off, 200 ms on	off	At least one device has signaled an error, e.g. that there is a module difference or that the error bit for an IO-CR is set (Problem Indicator)
flashing 200 ms	off	At least one device is signaling that its status is ‘Stop’ (Provider State Stop)
on	off	All PROFINET devices are in data exchange mode

If there are several different errors, then the error that is located at the top of (or higher in) the table is always displayed.

LEDs starting up

Run	PN Run/Err	PN Err	Meaning
off	off	off	No electrical voltage connected to E-bus. The EL6631 must be exchanged if EtherCAT terminals behind it function.
off	off	red on	EL terminal is starting up; after approx. 10 seconds, the LED should go out. If this does not happen, the EL6631 module must be exchanged.
