SIEMENS西门子S7

串行通信接口标准经过使用和发展，目前已经有几种。但都是在RS-232标准的基础上 经过改进而形成的。所以，以RS-232C为主来讨论。RS-323C 标准是美国EIA(电子工业联合 会）与BELL等公司一起开发的1969 年公布的通信协议。它适合于数据传输速率在0～ 20000b/s 范围内的通信。这个标准对串行通信接口的有关问题，如信号线功能、电器特性 都作了明确规定。由于通行设备厂商都生产与RS-232C制式兼容的通信设备，因此，它作为 一种标准，目前已在微机通信接口中广泛采用。-Serial communication interface standard through the use and development, now has several. However, in the RS-232 standard on the basis of an improved formed. So to the main RS-232C for discussion. RS-323C standard is the United States EIA (Electronics Industry Association) and BELL, such as the development of the company in 1969 with the publication of the communication protocol. It is suitable for data transfer rate at 0 ~ 20000b/s within the scope of communication. The standard serial communication interface of the relevant issues, such as signal line features, electrical characteristics have been clearly defined. Because of prevailing production and equipment manufacturers have standard RS-232C compatible communications equipment, t

实现图像控制,云台解码器控制,站点选择(配有Access数据库).-image control, pan and tilt control decoder, site selection (equipped with the Access database).

使用TC3.0开发的串口通讯程序，在一台电脑上模拟。（本机发到串口，本机再从串口读入）-TC3.0 development of the use of serial communication program, in a computer simulation. (This machine made to the serial port, the company was again read from the serial port)

PIC模拟异步串行通讯UART。用TMR0实现定时查询。任何带中断的PIC上都可以实现。可用此法扩展多个串口。-PIC simulation asynchronous serial communications UART. Timing TMR0 with inquiries. Any interruption with the PIC are to be attained. This method can be extended serial number.

西门子300的一个程序。是和HMI（WINCC）集成的一个程序-Siemens 300 a procedure. Is HMI (WINCC) integration of a program

Visual C++ 串口通信技术与工程实践配套（代码）3.3节-Visual C++ Serial communication technology and engineering practice of matching (Code) 3.3

这是一个红外温度探头测试程序，用于对温度探头进行测试，同时也可以作为温度采集用。由于探头通过RS232与计算机连接，所以程序包括串口通信的实现，串口通信利用了第三方通信类CSerial。程序可以将测得的数据保存为Excel文档。-This is an infrared temperature probe testing procedures used to test the temperature probe, but also used as temperature acquisition. As the probe through RS232 connection with the computer, including procedures for the realization of serial communications, serial communications using a third-party communications category CSerial. Procedures can be measured data to Excel document preservation.

可实现串口通信的DLL文件源码.通信速度快,易调试,占用系统资源少,非常实用.-serial communication can be realized DLL source. Communications faster, easier debugging, occupying less system resources. very practical.

串口编程-云台镜头控制系统,可以自由设置发送代码和串口选择。-Serial Programming- PTZ camera control system, can freely set the send code and serial port options.
