摘要
基于Modbus和TCP的通信原理,结合两者之间的优点,实现两者相结合的通信方式,使得Modbus通信协议可以通过以太网传输,扩展了Modbus协议的应用。在地铁直流供电系统上,通过Modbus-TCP通信协议,使得设备与设备之间在以太网上实现了远程通信,对地铁直流供电系统的信息传输具有一定的实用价值。
Communication theory based on Modbus and TCP, combined with the advantages of both, realizes the combination of the two modes of communication, and the Modbus communication protocol can be transmitted through Ethernet, which extends the applications of Modbus protocol. In the subway DC power supply system, through Modbus-TCP communication protocol, the equipment and the equipment in the Ethernet can achieve the remote communication with each other, which has a certain practical value to the information transmission for the subway DC power supply system.
