计算机和网络已经进入后PC 时代，随着将以太网应用到工业自动化领域的研究再次兴起，在现场仪表和工业设备层应用以太网技术是工业控制网络的一个发展趋势。本文研究开发了一种基于工业以太网的工业现场智能控制模块的硬件结构，选择合适的微处理器和外围存储、通信等器件，构建了一个带有网络接口，可以接入工业以太网现场网络中的硬件平台。关键字: 智能控制；工业以太网；网络接口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.Keywords: Intelligent Control; Industrial Ethernet; Network Interface
