摘要
西门子设备有多种不同的现场总线协议,如 MPI、PROFIBUS、PROFINET、S7 协议等,同时也支持开放式以太网通讯.S7-1500 系列定义的开放式以太网通讯即OPENE通信,主要有TCP、ISO-n-TCP、UDP三种通讯方式.本文针对该三种基于以太网的开放式通讯,详细描述其通讯建立、实现两台设备数据交换的应用方案.
Abstract
Siemens devices have many different fieldbus protocols,such as MPI,PROFIBUS,PROFINET,S7 protocol,etc.,and also support open Ethernet communication,which is defined by the S7-1500 series as OPENE communication,and there are mainly three communication modes,namely,TCP,ISO-n-TCP and UDP.In this paper,for the three kinds of Ethernet-based open communication,describes in detail its communication establishment,the realization of the application of data exchange between two devices.
