LEDs and connection

LEDs

LED	Color	Meaning
RUN PRIM	green	LED for indicating the operating state of the primary EtherCAT strand (terminal):
		off	State of the EtherCAT State Machine: INIT = initialization 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
		flickering	State of the EtherCAT State Machine: BOOTSTRAP = function for terminal firmware updates
RUN SEC	green	LED for indicating the operating state of the primary EtherCAT strand:
		off	State of the EtherCAT State Machine: INIT = initialization 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
		flickering	State of the EtherCAT State Machine: BOOTSTRAP = function for terminal firmware updates
X1/X2	green	off	No connection to EtherCAT network
		on	Connection to EtherCAT network established (LINK)
		flickering	Data exchange with devices in the EtherCAT network (ACT)

Connection

Terminal point	Description
X1	EtherCAT Input (RJ45 with 10BASE-T/100BASE-TX Ethernet)
X2	EtherCAT output (RJ45 with 10BASE-T/100BASE-TX Ethernet)
X3	2-pole socket terminal connection (24 V_DC), secondary side power supply
