准确计算加工工件的数量,在很多行业都积累了丰富的经验,从电动计数、集成电路到计算机数码显示各具特色。本文以JD-40可编程序控制器(PC)为例介绍一种既简单、方便,又直观、经济的计数方法。 1计算单元的扩展 JD-40每个计数单元最大计数值是127。为满足生产需要,必须用若干个计数单元配合使用,以扩大计数范围。图1是两个计数单元配合应用的基本形式。
Accurately calculate the number of workpiece, in many industries have accumulated rich experience, from the electric count, integrated circuits to the digital display of computers have their own characteristics. In this paper, JD-40 programmable logic controller (PC) as an example to introduce a simple, convenient, intuitive and economical counting method. 1 Calculation Unit Expansion JD-40 The maximum count value per counting unit is 127. To meet production needs, you must use a number of counting units together to expand the count range. Figure 1 is the basic form of two counting units with the application.
