ABB CI854AK01 3BSE030220R1通信接口介绍通信接口(communication interface)是指中央处理器和标准通信子系统之间的接口。如:RS232接口。RS232接口就是串口,电脑机箱后方的9芯插座,旁边-般有”|0|0|””样标识。-般机箱有两个,新机箱有可能只有一个。笔记本电脑有可能没有。有很多工业仪器将它作为标准通信端口。通信的内容与格式一般附在仪器的用户说明书中。计算机与计算机或计算机与终端之间的数据传送可以采用串行通讯和并行通讯二种方式。由于串行通讯方式具有使用线路少、成本低,特别是在远程传输时,避免了多条线路特性的不-致而被厂泛采用。在串行通讯时,要求通讯双方都采用-个标准接口,使不同的设备可以方便地连接起来进行通讯。RS-232-C接口(又称EIA RS-232-C)是目前最常用的一种串行通讯接口。它是在1970年美国电子工业协会(EIA)联合贝尔系统、调制解调器厂家及计算机终端生产厂家共同制定的用于串行通讯的标准。它的全名是“数据终端设备(DTE)和数据通讯设备(DCE)之间串行二进制数据交换接口技术标准”该标准规定采用一-个25个脚的DB25连接器,对连接器的每个弓|脚的信号内容加以规定,还对各种信号的电平加以规定。

ABB CI854AK01 3BSE030220R1 communication ports The communication interface is the interface between the central processing unit(CPU)and the standard communication subsystem.For example,an RS232 interface.RS232 interface is a serial port,9 core socket in the rear of the computer case,next to-like”|||0 0″sample”logo.-Normal case has two,the new case may only have one.Laptops probably don’t.Many industrial instruments use it as a standard communication port.The content and format of the communication are usually attached to the instrument’s user manual.Data transmission between computer and computer or between computer and terminal can adopt serial communication and parallel communication.Because serial communication has fewer lines and low cost,especially in remote transmission,it avoids the characteristics of multiple lines and is widely used by factories.In serial communication,both sides of the communication are required to adopt a standard interface,so that different devices can be easily connected for communication.RS-232-C interface(also known as EIA RS-232-C)is one of the most commonly used serial communication interfaces.It was developed in 1970 by the Electronic Industry Association(EIA)in collaboration with Bell Systems,modem manufacturers,and computer terminal manufacturers for serial communication.Its full name is”the data terminal equipment(DTE)and data communications equipment(DCE)between the serial binary data exchange interface technology standard”the standard adopts a-a DB25 connector of 25 feet,the content of the signal of each bow|feet for connector is regulated,also is regulated to a variety of signal level.
