日期：2021-11-12个人计算机（以下简称PC）具有较强的数据处理功能，配备着多种高级语言，若选择适当的操作系统，则可提供优良的软件平台，开发各种应用系统，特别是动态画面显示等。随着工业PC的推出，PC在工业现场运行的可靠性问题也得到了解决，用户普遍感到，把PC连入PLC应用系统可以带来一系列的好处。
1. PC与PLC实现通信的意义
把PC连入PLC应用系统具有以下四个方面作用：
1）构成以PC为上位机，单台或多台PLC为下位机的小型集散系统，可用PC实现操作站功能。
2）在PLC应用系统中，把PC开发成简易工作站或者工业终端，可实现集中显示、集中报警功能。
3）把PC开发成 PLC编程终端，可通过编程器接口接入PLC，进行编程、调试及监控。
4）把PC开发成网间连接器，进行协议转换，可实现PLC与其它计算机网络的互联。
2. PC与PLC实现通信的方法
把PC连入PLC应用系统是为了向用户提供诸如工艺流程图显示、动态数据画面显示、报表编制、趋势图生成、窗口技术以及生产管理等多种功能，为PLC应用系统提供良好、物美价廉的人机界面。但这对用户的要求较高，用户必须做较多的开发工作，才能实现PC与PLC的通信。
为了实现PC与PLC的通信，用户应当做如下工作：
1）判别PC上配置的通信口是否与要连入的PLC匹配，若不匹配，则增加通信模板。
2）要清楚PLC的通信协议，按照协议的规定及帧格式编写PC的通信程序。PLC中配有通信机制，一般不需用户编程。若PLC厂家有PLC与PC的专用通信软件出售，则此项任务较容易完成。
3）选择适当的操作系统提供的软件平台，利用与PLC交换的数据编制用户要求的画面。
4）若要远程传送，可通过Modem接入电话网。若要PC具有编程功能，应配置编程软件。
3. PC与PLC实现通信的条件
从原则上讲，PC连入PLC网络并没有什么困难。只要为PC配备该种PLC网专用的通信卡以及通信软件，按要求对通信卡进行初始化，并编制用户程序即可。用这种方法把PC连入PLC网络存在的唯一问题是价格问题。在PC上配上PLC制造厂生产的专用通信卡及专用通信软件常会使PC的价格数倍甚至十几倍的升高。
用户普遍感兴趣的问题是，能否利用PC中已普遍配有的异步串行通信适配器加上自己编写的通信程序把PC连入PLC网络，这也正是本节所要重点讨论的问题。
带异步通信适配器的PC与PLC通信并不一定行得通，只有满足如下条件才能实现通信。
1）只有带有异步通信接口的PLC及采用异步方式通信的 PLC网络才有可能与带异步通信适配器的PC互连。同时还要求双方采用的总线标准一致，都是RS-232C，或者都是RS-422（RS-485），否则要通过“总线标准变换单元”变换之后才能互连。
2）要通过对双方的初始化，使波特率、数据位数、停止位数、奇偶校验都相同。
3）用户必须熟悉互联的PLC采用的通信协议。严格地按照协议规定为PC编写通信程序。在PLC一方不需用户编写通信程序。
满足上述三个条件，PC就可以与PLC互联通信。如果不能满足这些条件则应配置专用网卡及通信软件实现互联。
4. PC与PLC互联的结构形式
用户把带异步通信适配器的PC与PLC互联通信时通常采用如图7-12所示的两种结构形式。一种为点对点结构，PC的COM口与PLC的编程器接口或其它异步通信口之间实现点对点链接, 如图7-12a所示。另一种为多点结构，PC与多台PLC共同连在同一条串行总线上，如图7-12b所示。多点结构采用主从式存取控制方法，通常以PC为主站，多台PLC为从站，通过周期轮询进行通信管理。
图7-12 常用结构形式
a）点对点结构 b）多点结构
5. PC与PLC互联通信方式
目前PC与PLC互联通信方式主要有以下几种：
1）通过PLC开发商提供的系统协议和网络适配器，构成特定公司产品的内部网络其通信协议不公开。互联通信必须使用开发商提供的上位组态软件，并采用支持相应协议的外设。这种方式其显示画面和功能往往难以满足不同用户的需要。
2）购买通用的上位组态软件，实现PC与PLC的通信。这种方式除了要增加系统投资外，其应用的灵活性也受到一定的局限。
3）利用PLC厂商提供的标准通信口或由用户自定义的自由通信口实现PC与PLC互联通信。这种方式不需要增加投资，有较好的灵活性，特别适合于小规模控制系统。
