IS215UCVEH2A可编程逻辑控制器的工作可靠、可编程，适用于各种工业环境下的应用

可编程逻辑控制器的专业名称叫做PLC，实质上是一种专用于工业控制的计算机，其硬件结构基本上与微型计算机相同。从结构上分，PLC分为整体式和组合式两种：
– 固定式PLC：包括CPU板、1/O板、显示面板、内存块、电源等，这些元素组合成一个不可拆卸的整体。
– 模块式PLC：包括CPU模块、1/O模块、内存、电源模块、底板或机架，这些模块可以按照一定规则组合配置。

整体式PLC一般还配备有特殊的功能单元，如模拟量单元、位置控制单元等，使其功能得以扩展。这类PLC特点包括结构紧凑、体积小、价格低，小型PLC一般采用这种整体式结构。

可编程逻辑控制器（Programmable Logic Controller，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。

可编程逻辑控制器由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。早期的可编程逻辑控制器只有逻辑控制的功能，所以被命名为可编程逻辑控制器，后来随着不断地发展，这些当初功能简单的计算机模块已经有了包括逻辑控制、时序控制、模拟控制、多机通信等各类功能，名称也改为可编程控制器(Programmable Controller)，但是由于它的简写PC与个人电脑(Personal Computer)的简写相冲突，加上习惯的原因，人们还是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。

The professional name of programmable logic controller is PLC, which is essentially a computer dedicated to industrial control, and its hardware structure is basically the same as that of a microcomputer. In terms of structure, PLC is divided into two types: integral and combined:
– Fixed PLC: including CPU board, 1/O board, display panel, memory block, power supply, etc., these elements are combined into a non-removable whole.
– Modular PLC: includes CPU module, 1/O module, memory, power module, baseboard or rack. These modules can be combined and configured according to certain rules.

Integral PLC is also generally equipped with special functional units, such as analog units, position control units, etc., so that its functions can be expanded. This type of PLC features include compact structure, small size, low price, small PLC generally adopt this integral structure.

A Programmable Logic Controller (PLC) is a digital operational electronic system designed specifically for use in industrial environments. It uses a programmable memory in which the instructions for performing operations such as logical operations, sequence control, timing, counting and arithmetic operations are stored, and various types of mechanical equipment or production processes are controlled through digital or analog input and output.

Programmable logic controller is composed of CPU, instruction and data memory, input/output interface, power supply, digital analog conversion and other functional units. The early programmable logic controller only has the function of logic control, so it is named programmable logic controller. Later, with the continuous development, these computer modules with simple functions have various functions including logic control, timing control, analog control, multi-machine communication, etc. The name was also changed to Programmable Controller, but due to the conflict between the abbreviation PC and the abbreviation Personal Computer, and for reasons of custom, the term programmable logic controller is often used and the abbreviation PLC is still used.

Programmable logic controllers work reliably and programmably, and are suitable for applications in various industrial environments.
