WINCC 有好多版本,此处以TIA WINCC professional 为例;
首先要在目标机器上安装一个runtime,具体又分Advanced,professional,unified..

可以看到有三种方式,分别是下载到设备,扩展下载到设备和下载到文件夹;如果组态的项目是Advanced的版本,则只有前面2者。如下

1.扩展的下载,可以通过网络下载到目标设备中;
2.下载到文件,适合把项目通过U盘等介质拷贝到目标设备,方便传送给别人,同时有一定的保护作用;在目标设备上找到程序文件夹的位置,打开即可;同时还可以设置开机自动启动等选项;


关于下载到设备和扩展的下载到设备的区别,如下:
If you had previously established an online connection, the "Load preview" dialog opens. This dialog displays messages and proposes actions necessary for downloading.
If you had not previously established an online connection, the "Extended download to device" dialog opens, and you must first select the interfaces via which you want to establish the online connection to the device. You have the option of showing all compatible devices by selecting the corresponding option and clicking the "Start search" command.
基本区别就是:之前是不是在线过了,在线过了就直接下好了,没有的话就扫描一下,先找到目标位置;
