用三菱编程指令，STC单片机上的模拟电位器数据如何采集_CMS教程

可以的，你可以用三菱PLC的专用协议配合STC程序通过串口通讯。或用自由协议，自由协议比较复杂，但STC那边实现起来比较简单直接用串口按规则把电位器的值发送出来，在PLC这边写程序接收解析，PLC这边比较复杂，需要一定的编程功底。

具体的PLC专用协议，自由协议参考你可以去三菱官网下载电子档说明书，以上2种协议我都成功应用在设备上。

（需要外扩通讯板。）

优缺点：PLC专用协议STC那边需要遵守PLC固定的数据格式比如0530304646（WW指令）相对PLC那边就简单的多，因为数据直接写到了指定的寄存器内（如D，M等），可以直接使用。

PLC自由协议STC按照普通的串口发送数据方式按自己固定的格式将AD数据发送，PLC这边程序比较复杂，需要理解PLC的自由协议写法（如RS指令）并利用一定的算法将数据还原并保存到寄存器内。

stc单机片程序备份出来的方法如下：

1、把单片机中的程序拷贝出来主要需要使用专业的烧录器，用烧录器来读取单片机中的程序，然后将程序文件保存即可。

2、可以使用其他的调试软件来读取单片机中的程序，然后将程序文件保存至电脑中。
