摘要
对工业以太网目前实现的方案进行研究 ,阐述了目前基于封装技术的现场总线与TCP IP相结合的 2种基本解决方案。对最新工业以太网应用协议EtherNet IP的协议封装技术进行了详细地分析 ,在此基础上给出了一个典型的EtherNet IP的应用的实例。对于EtherNet IP典型的 3种数据传输类型及其特点进行了对照比较 ,并对EtherNet IP的WEB服务也进行了介绍。
By researching the realized methods of industrial Ethernet in present, two basic solution methods which based on the encapsulation types between FieldBus and TCP/IP are expatiated. This paper analyses the protocol encapsulation technology of EtherNet/IP which is the newest industrial Ethernet application protocol in detail and gives an application example of this new protocol. Three definitions are used to help explain the EtherNet/IP transmission types.Web server capability which builds in EtherNet/IP is introduced.
