c# plc modibus 通信
c# 串口 以太网通信 modibus 连接 plc
从文本框输入负数 -2 补码=反+1=进位+原数
Vb 清除输入缓冲区 输出缓冲区 c#用不用清除？？哪个函数？？
//發送二進制數據 ？？？？？？？？？？？？？？
private void SendBytesData(SerialPort serialPort)
{ ////从 文本框取得数据 如果负数 -2 怎么办？？？？
byte[] bytesSend = Encoding.Default.GetBytes(txtSend.Text);
spcom.Write(bytesSend, 0, bytesSend.Length);
}
通过MODBUS TCP读写PLC源码
功能模块一：读写PLC主模块
using System;
using System.Net;
using System.Net.Sockets;
public static void WriteWord(int mwAddress,int mwValue)
{写字到以太网
if (init_plc() == 0)
{
try
{
hi = mwAddress / 256;
low = mwAddress - hi * 256;
hi1 = mwValue / 256; ///////////16bit
low1 = mwValue - hi * 256;
sendBuf[7] = 6;
sendBuf[8] = (byte)hi;
sendBuf[9] = (byte)low;
sendBuf[10]

一个由台湾人编写的课程设计
一个由台湾人编写的课程设计---IP多播 流媒体影音传输，涉及到视频采集，编码（directshow），传输（jrtplib），解码，播放。我做毕业设计时参考过。
其中包括整个程序的框架说明ppt，相信对大家非常有用，其中注释为繁体中文，可用ue阅读源文件，不过不是很多。-The people of Taiwan to prepare a curriculum design--- IP multicast streaming media audio and video transmission, related to video capture, encoding (directshow), transmission (jrtplib), decoding, playing. I have graduated from the design reference. Including the framework that the entire process ppt, believe that very useful for all of us, including the Notes, Traditional Chinese, ue can be used to read the source file, but not many.

的sl11ride是一种低成本、高速通用串行总线基于RISC控制器…
The SL11RIDE is a low cost, high speed Universal Serial Bus RISC based Controller board. It contains a
16-bit RISC processor with built in SL11RIDE ROM to greatly reduce firmware development efforts. Its
serial flash EEPROM interface offers low cost storage for USB device configuration and customer product
specific functions. New functions can be programmed into the I2C by downloading it from a USB Host
PC. This unique architecture provides the ability to upgrade products, in the field, without changing the
peripheral hardware.-USB IDE solution
