摘要
采用MODBUS协议及MODBUS协议的RTU模式,完成了MODBUS协议的编写、协议底层硬件电路的设计和协议模块的软硬件调试,实现了DSP与PLC之间的数据传输。
This article, applying MODBUS protocol and its RTU mode, compiled MODBUS protocol, designed the hardware circuit of the bottom layer protocol and debuged software and hardware . It also achieved the data transformation between DSP and PLC.
