C# 通过网络和三菱的PLC通信

这是一个测试UDP数据包的丢包率的程序，包含程序源码，已经验证成功(This is a test UDP packet loss rate of the program, including program source code, has been successfully verified)

基于W5500芯片的ping功能，使用W5500ping通其他设备(W5500 chip based on the ping function, the use of W5500ping through other devices)

MFC网络实验，实现多人聊天。包括服务器和客户端程序，使用Socket编程。(MFC socket program. )

用C#编写的独立UDP客户端，默认绑定地址127.0.0.1 端口为：9003，配合服务器使用，打开服务，与客户端建立连接即可通信(UDP server with independent written in C#, default binding address 127.0.0.1 port: 9003, with the clients, and to open the service, you can establish a communication connection with the client)

：本系统属于小型的局域网监控系统，可以对某一台计算机进行屏幕监控，本系统主要实现以下功能：  系统采用人机交互的方式，界面美观友好。  屏幕信息需要时时显示，网络延时不能大于1秒。  服务器端可以随时运行，只要客户端运行，就能够显示屏幕信息。  系统运行时占用内存不能大于10MB，以免影响系统性能。  客户端运行时需要隐藏显示窗口，起其感觉不到在运行(network monitoring system that can carry out the screen of a computer monitor, the system achieve the following features:  system is the way human-computer interaction, interface, beautiful and friendly.  need to constantly display screen information, the network delay is not greater than 1 second.  server can be run at any time as long as the client runs, will be able to display information.  run-time memory for the system can not be larger than 10MB, so as not to affect system performance.  need to hide the client run-time display window, from its feel in the run.)

这是一个简单的socket编程例子，非常适合刚接触socket编程者。程序简单、可用、易于理解。是个很好的socket范例。(A simple socket programming examples. Suitable for beginners. Program is simple, available, easy to understand. Is a good example of socket programming.)

对TCPIP网络包解析，Win下网络编程参考源码(TCPIP network packets for analysis, Win Network Programming Reference Source)

说明：  在多跳无线网络进行TDMA方式接入时候，时间是被划分为互不重叠的时隙，边长或定长帧在时隙中进行传输。 当面向节点时候，一个节点可以得到一个或者多个时隙，节点可以利用这些时隙向任何一条链路发送报文到邻居节点。 面向链路分配时候，则是某条单向链路分得一个或多个时隙，在这些时隙中，报文发送是单向的。(Time is divided into non-overlapping slots when multi-hop wireless networks are accessed by TDMA mode. Side-length or fixed-length frames are transmitted in slots. When facing a node, a node can get one or more slots, which can be used by the node to send messages to any link to its neighbors. For link allocation, a one-way link is allocated one or more slots, in which message transmission is one-way.)

实际上是两个project wj,cpp3,wj是服务端程序,cpp3是客户端程序(Is actually two project- wj, cpp3, wj is a server-side program, cpp3 is the client program)

从计算机某个UDP端口接收数据并且按照一定格式解析后存放于数据库中(UDP data receive program)
