For example, if the LEDs are shown as the following gure, it indicates that Modbus communication of
addresses 1, 5, 6, 7, 12, 15, 16, 18, 19, 21, 22, 23, 25, 26 and 27 is abnormal, and Modbus communication
of other addresses is normal. CANbus communication state displayed by the LED is 3, indicating normal
communication.
