There is a strong interest of using cheap and simple Ethernet technology for industrial network. However, traditional way uses a microcontroller (such as Rabbit 2000) in 8 bit mode, which cannot meet the demands of industrial communication. In order to realize communication over industrial Ethernet in 32 bit mode, this paper describes a method using S3C4510B 32 bit RISC microprocessor and uClinux embedded OS to realize industrial communication. The hardware of network interface and software development under uClinux was also present. The application result shows that the application has low cost but well performance in industrial field
