说明：  自动化领域上位机通过OPC服务读取三菱Q系列PLC的方法(How to read Mitsubishi Q series PLC through OPC service)

一个新的通信协议,一线通协议模版软件,希望对大家开发有用()

本程序是关于串口通信，已经调试通过，希望对大家有所帮助。(RS485)

标准串口win32接口函数,通过这些微软提供的串口接口函数可以实现对串口的读写操作(standard serial port debug source code)

串口调试助手，适合做串口通讯的人员使用。VB.NET编程。(vb.net serial debug for usart comm.)

说明：  我所见过用VC写的最好的串口类，具有模拟单片机中断传输的方式，避免了查询传输CPU损耗和接收超时(I have ever seen VC was the best serial category, with simulation SCM interruption of transmission, so that the CPU for transmission and reception of overtime loss)

串口编程控件MSCOMM32.OCX mscomm32.ocx是微软提供的串口通讯开发控件。支持串口通讯的软件大部分都是使用这个控件来实现串口通讯功能的。 安装方法:请您把它复制到系统目录下,对于windows9x系列(win95、win98、winme)是x:windowssystem,对于 windowsNT、windows2000、windowsXP系列是x:winntsystem32。然后打开一个命令行提示符窗口(MSDOS方式窗口), 用"cd x:windowssystem"命令或者"cd x:winntsystem32"切换到系统目录下,再执行"regsvr32 mscomm32.ocx"这个命令。 (MSCOMM32.OCX mscomm32.ocx control is provided by Microsoft Serial communications development controls. Support serial communication software is used most of the controls to achieve serial communications capability. Installation Method : Would you please copy it to the system directory, windows9x Series (win95. win98, WINME) x : windows system . for Windows NT, by Windows, windowsXP series of x : winnt system32 . Then open a command line prompt window (MSDOS mode window), "cd x : windows system "orders or" cd x : winnt system32 "switched to the system directory, further implementation of the "typing mscomm32.ocx" This order.)

C# 串口调试助手源代码。检测串口通信，能通过界面修改com的各项参数的设置，增加实现16进制的发送和接收(COM Tools Source code which is written in C#)

RS-232串口通讯编程，使用C#代码实现(Implementation of RS232 Communication C#)

超低速的光纤一体发接收发送器,同于以前的光纤一体化接头都只适用于2M以上的通讯,如需将232等低速信号用光纤传输出,需要加复杂的调制解调电路,网动光电新生产的这款光纤头主要针对低速信号,可以传送DC-500KPS的信号,极大地简化了硬件设计.(Ultra-low-fat whole-speed fiber-optic transmitter receiver with fiber-optic integration in the previous joint only applies to more than 2M communications, etc. For the 232 low-speed optical fiber transmission of signals, the need to increase the complexity of the modulation and demodulation circuit, the net move Photoelectric new production of this first major response to low-speed fiber-optic signal, DC-500KPS can send the signal, greatly simplifying the hardware design.)
