S3 (Sercos III) LED Indicator

LED indicator color / status	Description	Instructions / information for the user
Off	The device is not energized or is otherwise inoperable, or there is no communication due to an interrupted or separated connection.	Start Sercos boot up or verify the Sercos cable and connections.
Steady green	Active Sercos connection without an error detected in the CP4.	–
Flashing green (2 Hz, 250 ms)	The device is in loopback mode. Loopback describes the situation in which the Sercos telegrams have to be sent back on the same port on which they were received. Possible causes: Line topology or Sercos loop break	Workaround: Close ring. Reset condition: Acknowledge the detected error in the EcoStruxure Machine Expert Logic Builder menu Online > Reset diagnostic messages of controller. Switch from CP0 to CP1 alternatively. NOTE: If during phase CP1 a line topology or ring break was detected (device in loopback mode), the LED indicator condition does not change.
Steady red	Sercos diagnostic class 1 (DC1) an error has been detected on port 1 and/or port 2. No Sercos communication possible on the ports.	Reset condition: Acknowledge the detected error in the EcoStruxure Machine Expert Logic Builder menu Online > Reset diagnostic messages of controller.
Flashing red / green (2 Hz, 250 ms)	Communication error has been detected. Possible causes: Improper functioning of the telegram CRC error detected	Reset condition: The configuration shows which error has been detected. Acknowledge the detected error in the EcoStruxure Machine Expert Logic Builder menu Online > Reset diagnostic messages of controller.
Steady orange	The device is in a communications phase CP0 up to and including CP3 or HP0 up to and including HP2. Sercos telegrams are received.	–
Flashing orange (4 Hz, 125 ms)	Device identification	–

State LED Indicator

LED indicator color / status	Description	Instructions / information for the user
Off	Device is not energized or is otherwise inoperable.	Verify the power supply. Replace device.
