摘要
通讯系统采用Modbus协议下的RTU模式进行数据传输。系统采用组态软件开发上位机,MSP430单片机作为下位机,给出部分关键程序源代码。与ASCII模式相比,在相同的工作波特率条件下,RTU模式可以传输更多的数据,且系统稳定性更强。最终能够实现数据采集系统运作正常。
Communication system use the Modbus RTU protocol for data transmission. The system is developed by using the King View, the Single chip microcomputer of MSP430 is the Lower machine,giving some important source code. Compared with the ASCII mode, in the same baud rate under the RTU mode, The system can transmit more data, and be more stable. Finally the system can achieve data acquisition normally.
