If the RS-485 protocol fails somewhere, does the device still work?

The integrated sensor normally does not have a problem with the RS-485 protocol somewhere. The address of a single sensor on the integrated device is fixed and not the same. Even if a communication exception is caused by a failure, the whole device will not be affected.  
 
If the customer integrates, the above problems may be caused by the same address of multiple sensors.  If the communication protocol is abnormal, power-on will not communicate.  The default data formats for RS-485 communication are 9600, N, 8, and 1 (baud rate 9600 BPS, 1 start bit, 8 data bits, no check, and 1 stop bit).
