摘要
研究与实现了基于Modbus通讯协议的KNT―WP01型光伏发电系统监控模块。Modbus通信有两种传输方式,ASCII与RTU模式。RTU模式有较高的字符密度,在同样的波特率下,比ASCII模式有更高的吞吐量。在监控模块中选用Modbus RTU数据传输方式,实践表明其串行通讯简单、通用性强并且使用方便,具有广泛的应用。
KNT-WP01-type monitoring module based on Modbus communication protocol was researched and realized. There are two Modbus communication transmission modes, ASCII and RTU. RTU mode has a higher character density, which throughput is larger than the ASCII mode in the same baud rate.Practice shows selecting Modbus RTU data transmission in the monitoring module has a wide range of applications. Its serial communication is simple,versatile and easy to use.
