ABDT-PDP 可编程逻辑控制器 提高了工业生产的自动化水平

ABDT-PDP 可编程逻辑控制器（Programmable Logic Controller，简称PLC）是一种专门为在工业环境下应用而设计的数字运算操作电子系统。它采用一种可编程的存储器，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，通过数字式或模拟式的输入输出来控制各种类型的机械设备或生产过程。PLC由CPU、指令及数据内存、输入/输出接口、电源、数字模拟转换等功能单元组成。早期的PLC只有逻辑控制的功能，因此被命名为可编程逻辑控制器。然而，随着技术的不断发展，PLC的功能得到了扩展，包括逻辑控制、时序控制、模拟控制、多机通信等，因此有时也被称为可编程控制器（Programmable Controller）。尽管其简写PC与个人电脑（Personal Computer）的简写相冲突，但由于习惯的原因，人们仍然经常使用可编程逻辑控制器这一称呼，并仍使用PLC这一缩写。ABDT-PDP PLC是一种计算机技术与自动化控制技术相结合而开发的新型通用自动控制装置，是作为传统继电器的替换产品而出现的。PLC的出现大大提高了工业生产的自动化水平和效率，因此在工业自动化领域得到了广泛应用。

ABDT-PDP

ABDT-PDP Programmable Logic Controller (PLC) is a digital operation electronic system designed specifically for industrial applications. It adopts a programmable memory that stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations inside, and controls various types of mechanical equipment or production processes through digital or analog input and output. PLC consists of functional units such as CPU, instruction and data memory, input/output interfaces, power supply, and digital to analog conversion. Early PLCs only had the function of logical control, so they were named programmable logic controllers. However, with the continuous development of technology, the functions of PLC have been expanded, including logic control, timing control, analog control, multi machine communication, etc., so it is sometimes referred to as a programmable controller. Although the abbreviation PC conflicts with the abbreviation Personal Computer, due to habitual reasons, people still frequently use the term programmable logic controller and still use the abbreviation PLC. ABDT-PDP PLC is a new type of universal automatic control device developed by combining computer technology and automation control technology. It has emerged as a replacement product for traditional relays. The emergence of PLC has greatly improved the automation level and efficiency of industrial production, and therefore has been widely used in the field of industrial automation.
