Modbus协议RTU模式与TCP模式的通信转换设计

Conversion of RTU mode and TCP mode in Modbus Communication Protocol

Modbus通信协议运用于电能优化管理系统中,需要将串行链路通信模式转换为以太网通信模式。在详细分析Mod-bus串行链路通信协议的基础上,分别实现了Modbus RTU模式和Modbus TCP模式的通信,然后完成了Modbus RTU与Modb-us TCP模式的通信转换。该方法为电能优化管理系统的通信和系统集中控制提供了良好的技术支持。

Modbus communication protocol is often used in power optimization management system,which has to convert serial link mode to Ethernet mode.After analyzing the Modbus serial link communication protocol,the communication of Modbus RTU mode and Modbus TCP mode is implemented separately,and then the communication conversion of Modbus RTU and Modbus TCP mode is achieued.This method offers good technical support for communication and central control of power optimization management system.
