1、各自技能开展的来源

核算机是为了满意快速大量数据处理要求的设备。硬件结构方面，总线标准化程度高，兼容强，软件资源丰富，特别是有实时操作体系的支持，故对要求快速、实时强、模型复杂和核算工作量大的工业对象的操控占有优势。

集散体系从工业自动化仪表操控体系开展到以工业操控核算机为中心的集散体系，所以其在模拟量处理、回路调理方面具有必定优势，初期主要用在连续进程操控，侧重回路调理功用。

PLC是由继电器逻辑体系开展而来，主要用在离散制作、工序操控，初期主要是替代继电器操控体系，侧重于开关量顺字操控方面。

近年来随着微电子技能、大规模集成电路技能、核算机技能和通信技能等的开展，PLC在技能和功用上发生了腾跃。在初期逻辑运算的基础上，增加了数值运算、闭环调理等功用，增加了模拟量和PID调理等功用模块;运算速度提高，的才能赶上了工业操控核算机;通信才能的提高开展了多种部分总线和网络(LAN)，因而也可构成为一个集散体系。特别是个人核算机也被吸收到PLC体系中。

PLC在进程操控的开展将是—智能变送器和现场总线，暨向下拓展功用，开放总线。

在微电子技能开展的背景下，从硬件的度来看，PLC、工业核算机、集散体系(DCS)之间的不同正在缩小，都将由类似的一些微电子元件、微处理器、大容量半导体存储器和I/O模件组成。编程方面也有很多相同点。

由于PLC和核算机属于两类产品，通过几十年的开展都构成了本身的装置特色和软件工具。实际上的区别持续存在。

PLC用编程器或核算机编程，编程言语是梯形图、功用块图、次序功用表图和指令表等。集散体系本身或用核算机结构构成组态构成开发体系环境.

特别提出的是与STD总线工控机的区别，无论从维修、装置和模件功用都很类似。PLC适用于黑模式下运转，但在线运转时若要进行较大的程序修改，其才能略逊于STD工控机，可是从开关量操控而言，PLC的能优于STD工控机。

总的来说，在选择操控器时，首要要从工程要求、现场环境和经济等方面考虑。没有什么操控器完善，也没有哪种产品差，只能说选择适用的产品。

PLC自问世以来，通过20多年的开展，在美国、欧洲、等工业发达国家已成为重要工业，197年国际PLC的销售额为25亿美元，此后每年以20%左右的速度递加。进入90年代以来，国际PLC的年平均销售额在55亿美元以上，其间我国约占1%。当时，PLC在市场上已成为受欢迎的工业操控畅销产品，用PLC规划自动操控体系已成为国际潮流

1. Origin of respective technological development

Computers are devices designed to meet the requirements of fast and massive data processing. In terms of hardware structure, the bus has a high degree of standardization, strong compatibility, and abundant software resources, especially with the support of real-time operating systems. Therefore, it has advantages in controlling industrial objects that require fast, strong real-time, complex models, and high computational workload.

Distributed systems have evolved from industrial automation instrument control systems to distributed systems centered around industrial control computers. Therefore, they have certain advantages in analog processing and loop regulation. Initially, they were mainly used in continuous process control, with a focus on loop regulation functions.

PLC is developed from relay logic systems and is mainly used in discrete manufacturing and process control. In the initial stage, it mainly replaced relay control systems, with a focus on switch quantity sequential control.

In recent years, with the development of microelectronics technology, large-scale integrated circuit technology, computer technology, and communication technology, PLC has made a leap in technology and functionality. On the basis of initial logical operations, functions such as numerical operation and closed-loop adjustment have been added, as well as functional modules such as analog quantity and PID adjustment; The computing speed has improved, and the ability to catch up with industrial control computers; The improvement of communication capabilities has led to the development of various local buses and networks (LANs), which can also form a distributed system. Especially personal computers have also been incorporated into PLC systems.

The development of PLC in process control will be intelligent transmitters and fieldbuses, as well as downward expansion of functions and open buses.

In the context of the development of microelectronics technology, from a hardware perspective, the differences between PLCs, industrial computers, and distributed systems (DCS) are narrowing, and they will all be composed of similar microelectronic components, microprocessors, large capacity semiconductor memories, and I/O modules. There are also many similarities in programming.

Due to the fact that PLC and computers belong to two categories of products, they have formed their own device characteristics and software tools after decades of development. The actual difference continues to exist.

PLC is programmed using a programmer or computer, with programming languages such as ladder diagrams, function block diagrams, sequential function table diagrams, and instruction tables. The distributed system itself or the development system environment formed by computer structure configuration

Specifically, the difference between STD bus industrial control computers is that they are very similar in terms of maintenance, installation, and module functions. PLC is suitable for operating in black mode, but if significant program modifications are required during online operation, its ability is slightly inferior to that of STD industrial control computers. However, in terms of switch value control, PLC's performance is superior to that of STD industrial control computers.

Overall, when selecting a controller, the first consideration should be given to engineering requirements, on-site environment, and economy. There is no perfect controller, and there is no product that is inferior. It can only be said to choose the applicable product.

Since its inception, PLC has become an important industry in industrialized countries such as the United States, Europe, and other countries after more than 20 years of development. In 197, the world's sales revenue of PLC was 2.5 billion US dollars, and since then, it has been increasing at a rate of about 20% annually. Since the 1990s, the average annual sales of PLC in the world have exceeded 5.5 billion US dollars, with China accounting for about 1%. Currently, PLC has become a popular industrial control best-selling product in the market, and using PLC to design automatic control systems has become a world trend
