说明：  C#写了一款上位机监控软件，基于MODBUS RTU协议。 软件的基本结构： 采用定时器（Timer控件）为时间片。 串口采用serialPort1_DataReceived中断接收，并进行MODBUS格式判断。 把正确接收的数据取出，转换为有特定的结构体中。 数据通过时间片实时刷新。 MODBUS协议
(C# write a PC monitoring software, based MODBUS RTU protocol. The basic structure of the software: using the timer (Timer Control) as a time slice. Serial port using serialPort1_DataReceived interrupt reception, and make judgments MODBUS format. Removing the correctly received data is converted to a specific structural body. Real-time data through the time slice refresh. MODBUS protocol)
