本文介绍了一种标识流图在顺序控制系统中建模方法,然后利用可编程序控制器中的步进指令实现控制。
The paper introduces a method of establishing model using mark flow graph in sequence control system. Then the control is implemented by step-by-step instruments in PLC.
So let's look at a little example, and this is going to, excuse me, both allow us introduce the syntax as well as what we want to have as the flow of control inside of here.
让我们看个小例子,这个程序会,对不对,请允许我,一边顺着控制流进行,一边讲解语法。
We decrement so to speak the variable and then where will we go next in terms of the flow control, the flow of this program.
可以这么说,我们递减这个变量,然后按照控制流,即程序流进入到下一语句。
So the way to think about this in terms of flow is, it starts with that if and it says, check both of those things.
因此用控制流的方式,来考虑这件事就是,程序由if开始,然后要对两件事情,都进行检查。
