Research on the Technology of RS485 over Ethernet

RS485 Bus is adopted in part of communication structure in the process of remote control communication. Different RS485 communication line is difficult to integrate due to different control systems and communication protocols. Based on this, this paper presents a method which can integrate the original RS485 communication line together without damaging the existing RS485 communication structure,that is the technology of RS485 over Ethernet .The above technology not only avoids multiple RS485 lines but also implements the access based on IP.
