可编程序控制器的功能指令在电气系统中的应用技巧

Skills of the functionly instructions of PLC in an electrical applianic system

叙述了可编程序控制器功能指令在工业控制中的一些巧妙应用.通过结合三菱公司FX2系列可编程序控制器的传送比较指令、数字运算指令、数据处理指令、移位指令和编解码指令等功能指令,详细举了4个例子,用功能指令来替代一些基本逻辑指令,使程序层次清晰,步骤简单又方便,把可编程序控制器的计算机特色的指令发挥出来了.

This paper expounds the skills of the functional instrunctions of PLC in industry applications. By use of MITSUBISHI ELECTRIC CORPORATION FX2N series PLC, MOV,CMP,ADD, DECOand SFTL instrunctions of the four detailed examples are given using the functional instrunction as a substitute for the logic instrunction. This programming levels easy and simple steps of fully utilizing the instructions of the computer PLC.
