可编程逻辑控制器简称PLC,是专为在工业环境下应用而设计的一种数字运算操作电子系统。它采用了可编程序的存储器,用来在其内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令,并通过数字量、模拟量的输入和输出,控制各种类型的机械或生产过程。根据多年的工作经验,主要针对PLC先进控制策略进行分析和讨论。
Programmable Logic Controller referred to as PLC, is designed for industrial applications in the design of a digital computing operation of electronic systems. It uses a programmable memory, which is used to store instructions for executing operations such as logic operations, sequence control, timing, counting and arithmetic operations, and to control various types of inputs and outputs through digital and analog inputs Mechanical or production process. Based on many years of work experience, mainly for PLC advanced control strategy analysis and discussion.
