我找出了全部 e开头h结尾的101个单词及其解释,没有你想要的估计是你把结尾写错了
应该是emotion情绪,感情,激动
EN代表使能,你梯形图前面的部分信号为1(也成为RLO信号为1)那就运行这个程序块。
ENO代表输出使能,也就是你这个程序块(或者系统自带的固定程序块)运行没有错误。
IN和OUT就是输入输出,你图中的MOVE指令是系统自带的,你也可以自己写其他的程序块。
以你的图中程序为例:
M04为1时,运行T45定时器,200100ms后,T45导通。在这里T45是TON,也就是延时导通定时器。时间是PT输入的值乘固定的100ms。
M04为1时,还并行了,将T45的数字以Word数据格式移动到VW100地址中。
最后一行是将你的RLO信号取反。也就是M04为0时,直接将T45以Word数据格式移动到VW100地址中。
刚学到这个,引用我们的教材答一波——《现代电气控制及PLC应用技术》王永华第四版。如下图。
文字版:在梯形图中,S7-200PLC用一个方框表示一条功能指令,这些方框称作指令盒。假想梯形图的母线能提供一种能流,并在梯形图中移动,每个指令盒都有一个使能输入端EN和一个使能输出端ENO。当EN端有能流,即EN端有效时,该指令被执行。若EN有能流且指令执行无误,则ENO为1,即ENO能把能流传递下去;若指令执行有误,则ENO为0,能流不能继续传递。请切记所有的功能指令只有在EN端有效时才被执行。
结合另外一个高赞回答加深一下理解。
求赞求采纳。
PLC中EN是什么意思
enable >>>使能
只有使能了 该指令才能才会执行
没有使能 该指令不执行
plc中,EN,ENO,IN,OUT是什么意思EN 就是使能
ENO 应该是输出的使能
IN 是输入
OUT 是输出
