Abstract: As the computer and the network entering a post PC period, and the using the Ethernet to the industry field is developed again, it’s a developing trend of the industry control network to use the Ethernet technology in the application of the field device. It introduces a new field intelligent control module based on the industrial Ethernet in this paper. It mainly describes the hardware structure of the network intelligent token control module. The system selects suitable MCU, memory, and communication devices, and built a hardware platform with network interface, which can enter the field network of the industry Ethernet.
