摘要
随着现场总线技术在低压电器领域的推广应用,具有网络通信功能的第四代低压电器成为当前的研发热点。本文通过对个人电脑的接口电路和软件进行配置,开展了在单台PC上进行Modbus的物理层、数据链路层和应用层的设计与仿真,实现了一种低成本、快速的Modbus协议仿真设计环境,并设计了一种具备基本通信功能的Modbus网络,对第四代低压电器通信系统的设计具有一定的工程应用价值。
With the application of field bus technology in the field of low voltage apparatus,the fourth generation of low voltage apparatus with the function of network communication has become the focus of present development.Through configuration of interface circuit and software for PC,design and simulation is conducted for physical layer,data link layer and application layer of Modbus on single PC.Based on that,a cost effective and rapid Modbus simulation design environment is realized and a Modbus network with basic communication function is designed,which has considerable engineering application value for the communication system design of the fourth generation of low voltage apparatus.
