Overview of RS-422 Communication Fault Classification and Causes

The RS-422 communication standard is widely used in industrial automation and communication fields, but in actual use, various communication faults are often encountered. This study aims to classify and analyze RS-422 communication faults to better understand the causes of the faults and provide corresponding solutions. By carefully analyzing common faults such as cable faults, environmental interference, signal attenuation, equipment faults and circuit design defect problems, the reliability and stability of RS-422 communication systems can be effectively improved.
