摘要
工业以太网是当前工业通信网络的主流技术。简单介绍了基于标准以太网的Modbus/TCP的基本概念,阐述了Modbus/TCP通信网关产品研制的硬件设计原理,着重分析了产品的软件架构及"并发"、"透传"数据传输的实现过程及数据,最后对"并发"、"透传"方式下数据传输实时性进行了对比分析。
Industrial EtherNet is the mainstream technology of the current industrial communication network.This article simply introduced the basic concepts of the Modbus /TCP based on standard EtherNet,described the hardware design principles of the Modbus /TCP gateway. It also analyzed the software architecture and the implementation process of the ＂concurrent＂and ＂pass-through＂data transmission. Finally,the real time data transmission in the two ways was compared.
