CP 343-1通讯处理器是用于SIMATIC S7-300通讯处理器。分担CPU的通讯任务并允许其它连接。

S7-300通过CP 343-1可与编程器、计算机、人机界面装置，其他SIMATICS7系统以及SIMATIC S5可编程序制器进行通讯：

CP 343-1通讯处理器安装在S7-300的DIN标准导轨上，可也可在扩展机架上安装，通过总线连接器与相邻模块相连接，没有插槽规则。

15针D形插座用于连接工业以太网；4针端子排用于连接外部24伏直流电源；RJ45插座用于进行工业以太网的快速连接。

CP 343-1在工业以太网上独立处理数据通信。该模块有其自身的处理器。使用ISO传输协议,TCP传输协议,UDP传输协议。并以多重协议方式实现PG／OP通讯,S5兼容通讯等通讯服务。通过ISO传输连接的数据通讯接口最多可传输8千字节的数据。

在STEP7系统下的网络的不同形式：

1 1个子网（subnet）-1个项目(project) 

2 SIMATIC S5与其他站在一个子网内 

3 2个或多个子网（subnet）-1个项目(project) 

4 1个子网（subnet）-多个项目(project) 

5 多个子网（subnet）-多个项目(project) 

6 子网（subnet）间的连接（ISO-on-TCP） 

CP-SEND（发送块）和CP-RECV（接收块）结构

CP-RECV（接收块）各端子参数的类型及功能

CP-SEND（发送块）各端子参数的类型及功能

多点接口（MPI）

S7—300／S7—400可以通过MPI接口组成PLC网络，MPI网采用全局数据(Globe Data)通信模式，可在PLC之间进行少量数据交换。它不需要额外的硬件和软件，成本低，用法简。

MPI网用于连接多个不同的CPU或设备．MPI符合RS—485标准，具有多点通信的性质．MPI的波特率设定为187．5kbps． 

二、多点接口（MPI）全局数据设置

GD通信的数据结构

GD通信应用

1．建立MPI站1的硬件组态

2．设置MPI站1的站地址

3．建立MPI站2的硬件组态，打开组态界面的CPU特性，设置MPI站2的站地址

4．点击Configure Network 进入配置网络界面

5．打开全局数据表 Options/Define Global Date

6．生成并装载全局数据，实现CPU到CPU通讯

发送/接收数据规则：1个MPI站的发送数据可以发送到多个MPI站，1个MPI站的接收数据只能接收1个MPI站的发送数据。

SIMATIC S7300（1）站和SIMATIC S7300（2）站的控制程序

网络的概念

通过线路互联起来的，自治的终端设备集合。

   将分布在不同地理位置上的具有独立工作能力的计算机、终端及其附属设备用通信设备和通信线路连接起来，并配置网络软件，以实现计算机资源共享的系统。

网络按网络拓扑划分

总线型，星型，.环型，网状， 树状， 星环型，拓扑。

二 网络的发展过程

1．具有通信功能的单机系统。该系统称为终端，是早期计算机网络的主要形式，它是将一台计算机通信线路与若干个终端直接相连

2．具有通信功能的多机系统。在简单的“终端——通信线路——计算机”这样的单机系统中，主计算机负担较重，既要进行数据处理，又要承担通信功能。

3．以共享资源为主要目的的计算机网络。既利用通信线路将多台终端设备连接起来，实现设备与设备之间的通信。

4．局域网络及其互连为主要支撑环境的分布式计算阶段。局域网是继远程网之后发展起来的小型终端设备网络，它继承了远程网的分组交换技术和计算机的I/O总线结构技术。并具有结构简单、经济实用、功能强大、方便灵活等特点。是随着微型计算机的广泛应用而发展起来的。
