For example, if the LEDs are shown as the following īægure, 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.
