Modbus协议是连接至不同类型总线或网络的设备之间提供主站／从站通信。在嵌入式系统中，FreeModbus使Mod-bus协议得以实现。采用FreeModbus支持的RTU传输模式，移植到STM32上，PC机上用Modbus Pol 作主站测试工具。经实验证明，成功实现了在串行链路上主站和从站之间数据实时通信。

Modbus protocol connects different types of bus or network equipment to provide the communication of the master/slave.ln the embedded system,FreeModbus makes Modbus protocol come true.lt transplants the RTU transmission mode which is supported by FreeModbus into the chip of STM32.The Modbus Pol is made to the main testing tools on PC.The experiment has proved that the data real-time communication between master and slave on the serial links is success.
