如上图，哪位朋友给我讲讲，麻烦将各个脚的作用也讲一下，谢谢

你去看书，书上都有介绍

赋值用的阿
MOVE (Assign a Value) is activated by the Enable EN Input. The value specified at the IN input is copied to the address specified at the OUT output. ENO has the same logic state as EN. MOVE can copy only BYTE, WORD, or DWORD data objects. User-defined data types like arrays or structures have to be copied with the system function "BLKMOVE" (SFC 20).

哪有这方面资料啊，我不是搞编程的，我只是想看懂我们的设备的组态图

看s7的帮助，基本功能都能知道了。

谢谢

哈哈，瓜的
