7.2.2 CAN LEDs

The CAN LEDs display the overall condition of the CANopen interface, once the startup sequence has completed. The LED codes conform to the CAN in Automation (CiA) DR303_3 indicator standard. The green LED indicates the state of the node’s internal CANopen ‘state machine’. The red LED indicates the state of the physical CANopen bus.
