安装在插板箱中，各现场控制单元及其与控制管理级之间采用总线连接，以实现信息交互。

　　现场控制单元的硬件配置需要完成以下内容：

　　插件的配置 根据系统的要求和控制规模配置主机插件（CPU插件）、电源插件、I/O插件、通信插件等硬件设备；

利用编码器、PLC、称重仪表、条码打印机、上位机组态软件在线监控功能,开发了一套基于PLC和工控机的标签打印控制系统,并给出了该系统的组成、工作原理、设计方案,重点说明了该系统的软件开发过程和现场实际工作效果,该系统具备自动化程度高、操作简单、响应快和故障率低等特点,值得大力推广。机型挑选的基本原则是在满意操控功用请求的前提下，保证体系工作牢靠、保护运用方便及好的功能报价比。详细应思考的要素如下所述。关于工艺进程比较固定、环境条件较好（修理量较小）的场合，选用全体式构造PLC，别的状况则选用模块式构造PLC。80025-523-10-R关于开关量操控的工程项目，对其操控速度无需思考，通常的等级低机就能满意请求。关于以开关量操控为主，带少量模拟量操控的工程项目，可选用等级低机。关于操控比较杂乱，操控功用请求更高的工程项目，例如请求完成PID运算、闭环操控、通讯联网等，可视操控规划及杂乱的程度选用中档或机。其间机首要用于大规划进程操控、全PLC的分布式操控体系以及悉数工厂的自动化等。一个大型企业应尽量做到机型一致。80025-523-10-R因为同一机型的PLC，其模块可交换，便于备用品、备件的采购和办理；其功用及编程办法一致，有利于技术力量的训练、技术水平的进步和功用的开发；其外部设备通用，资本可共享，配以上位核算机后，可把操控各独立的体系的多台PLC连成一个多级分布式操控体系，相互通讯，会集办理。80025-523-10-R容量的挑选PLC的容量包含用户存储器的存储容量（字数）和I/O点数两方面的意义。PLC容量的挑选除满意操控请求外，80025-523-10-R还应留有恰当的裕量以作备用。通常，一条逻辑指令占存储器一个字，计时、计数、移位以及算术运算、数据传送等指令占存储器两个字。80025-523-10-R各种指令占存储器的字数可查阅PLC商品运用手册。在挑选存储器容量时，通常可按实践需求的25%思考裕量。

通常I/O点数可按实践需求的10%～15%思考裕量。80025-523-10-R指令体系的挑选因为可编程操控器运用的性，各种机型所具有的指令体系也就不完全一样。从工程运用视点看，有些场合仅需求逻辑运算，有些场合需求杂乱的算术运算，80025-523-10-R而且一些特别场合还需求指令功用。从可编程操控器本身来看，各个厂家的指令区别较大，但从全体上来说，指令体系都是面向工程技术人员的言语，80025-523-10-R其区别首要表现在指令的表达方法和指令的完整性上。80025-523-10-R有些厂家在操控指令方面开发得较全，有些厂家在数字运算指令方面开发得较全，而大多数厂家在逻辑指令方面都开发得较完善。在挑选机型时，应从指令体系方面留意下述内容：指令体系的总句子数。80025-523-10-R它反映了悉数指令所包含的悉数功用。指令体系的品种。首要应包含逻辑指令、运算指令和操控指令，详细的需求则与实践要完成的操控功用有关。指令体系的表达方法。指令体系表达方法有多种，有的包含梯形图、操控体系流程图、句子表、顺控图、言语等多种表达方法；有的只包含其间一种或两种表达方法。运用软件的程序构造。80025-523-10-R程序构造有模块化的程序构造和子程序式的程序构造，种有利于运用软件编写和调试，但处理速度慢，后一种呼应速度快，但不利于编写和现场调试。软件开发手法。80025-523-10-R在思考指令体系这一功能时，还要思考到软件的开发手法。有的厂家在此基础上还开发了软件，80025-523-10-R可利用通用的微型机（例如IBM-PC）作为开发手法，这么就愈加方便了用户的需求。大量使用的是二极管的变流器，它把工频电源变换为直流电源。也可用两组晶体管变流器构成可逆变流器，由于其功率方向可逆，可以进行再生运转。 
平波回路
在整流器整流后的直流电压中，含有电源6倍频率的脉动电压，此外逆变器产生的脉动电流也使直流电压变动。为了抑制电压波动，采用电感和电容吸收脉动电压（电流）。装置容量小时，如果电源和主电路构成器件有余量，可以省去电感采用简单的平波回路。 [4] 
逆变器

同整流器相反，逆变器是将直流功率变换为所要求频率的交流功率，以所确定的时间使6个开关器件导通、关断就可以得到3相交流输出。以电压型pwm逆变器为例示出开关时间和电压波形。 [4] 
控制电路是给异步电动机供电（电压、频率可调）的主电路提供控制信号的回路，它有频率、电压的“运算电路”，主电路的“电压、电流检测电路”，电动机的“速度检测电路”，将运算电路的控制信号进行放大的“驱动电路”，以及逆变器和电动机的“保护电路”组成。 [4] 
（1）运算电路：将外部的速度、转矩等指令同检测电路的电流、电压信号进行比较运算，决定逆变器的输出电压、频率。 [4] 
（2）电压、电流检测电路：与主回路电位隔离检测电压、电流等。 [4] 
（3）驱动电路：驱动主电路器件的电路。它与控制电路隔离使主电路器件导通、关断。 [4] 
（4）速度检测电路:以装在异步电动机轴机上的速度检测器(tg、plg等)的信号为速度信号，送入运算回路，根据指令和运算可使电动机按指令速度运转。 [4] 

（5）保护电路：检测主电路的电压、电流等，当发生过载或过电压等异常时，为了防止逆变器和异步电动机损坏。 工业世界联网程度的提升有一个关键问题：如果发生网络攻击且攻击成功，后果不堪设想，比如，网络罪犯入侵计算机系统并切断城市供电或供水。而且，不仅网络犯罪团伙会盯上ICS，民族国家黑客也常将ICS列为攻击敌对国关键基础设施的入口点。正如2017年6月NotPetya数据清除恶意软件爆发所展现的，ICS已经成为网络犯罪的主要目标。然而，很多工控设备都面临安全措施老化过时的风险，需要进行替换或升级。如何应对ICS面临网络攻击风险的事实?公共事业机构该从哪里开始防御这种之前从未考虑过的威胁?

With the disappearance of the demographic dividend and the rise of labor costs, the low-cost advantage of China's manufacturing industry is gradually losing. The development of China's manufacturing industry is constrained by labor shortage, cost increase, overcapacity and global economic weakness. According to the data released by the National Bureau of Statistics, in 2015, the added value of China's industries above designated size increased by 6.1% over the previous year, and China's industrial growth has shifted from a high speed of more than 10% in the past to a medium high speed of less than 10%. Facing various pressures, automation and intelligence have become the inevitable trend of China's industrial development.

Industrial automation covers a wide area, has a long industrial chain, and the domestic market is nearly trillion yuan. According to the statistics of the German Industry 4.0 Working Group, the scale of China's automation market in 2012 has reached 800 billion yuan, ranking first in the world with 29% of the total. Driven by the improvement of automation degree and the transformation of stock market, the market scale of industrial automatic control system device manufacturing industry exceeded 350 billion yuan in 2015.

In the industrial chain of the entire industrial automation industry, the upstream is the raw materials, mainly including electronic components, power electronic components and sheet metal structures. In the middle reaches are intelligent control systems, while in the lower reaches are application industries, including electric power, metallurgy, elevators, machinery and other industries.

The intelligent control system is located in the middle of the entire industrial chain, which can be divided into three levels, namely, the control level, the driver level and the executive level. The control layer realizes the analysis, processing and distribution of tasks, such as PLC, DCS, etc; The drive layer decodes the tasks of the control layer into signals that can be recognized by motors, valves, etc., such as frequency converters and servo drivers; The executive level performs corresponding tasks, including motors, valves, etc. Control layer

With the development of microelectronic technology such as large-scale and ultra large-scale integrated circuits, PLC has developed from the original one bit computer to the current microcomputer PC composed of 16 bit and 32 bit microprocessors, and has realized multi-channel processing of multi processors. Today, PLC technology has become very mature. It not only enhances control functions, reduces power consumption and volume, reduces cost, improves reliability, and makes programming and fault detection more flexible and convenient.

At present, there are more than 200 PLC manufacturers and more than 400 varieties of PLC products in the world, among which the products of GE, Siemens, Omron, Mitsubishi, Schneider and other large international manufacturers account for more than 80% of the global PLC market share. Most of the domestic PLC market is occupied by foreign products. However, in recent years, with the continuous expansion of China's PLC market, domestic enterprises such as Delta, Huaguang and Xinjie are also gradually making efforts.

The future development trend of PLC is: first, to develop in the direction of high speed and large capacity; second, to develop in the direction of super large and super small; third, to vigorously develop intelligent modules of PLC to strengthen networking communication capabilities; fourth, to diversify programming languages.

Driver layer

Both frequency converter and servo driver are AC motor drivers. In industrial applications, frequency converter is generally used for speed control and torque control where requirements are not very high, and AC servo driver can only be used for strict position control requirements. In addition, the response speed of the servo is far greater than that of the frequency conversion, and some occasions with high requirements for speed accuracy and response are also useful for AC servo driver control.

In the past, the strength and scale of domestic inverter enterprises were uneven, and imported products accounted for most of the domestic inverter market. In recent years, after years of development, the local inverter brand has gradually expanded its market share, and has changed from simply providing products to providing users with systematic solutions. At present, the frequency converters in the market are gradually becoming diversified. The emergence of general-purpose and special-purpose products has met the diverse needs of users and provided a basis for capturing the high-end market.

The development trend of AC servo driver is generalization, intelligence, networking and modularization. The universal driver is configured with a large number of parameters and rich menu functions, which is convenient for users to set up various working modes without changing the hardware configuration. It is suitable for various occasions and can drive different types of motors; Modern AC servo drivers have the functions of parameter memory, fault self diagnosis and analysis. Some can automatically identify motor parameters, automatically measure encoder zero position, and some can automatically suppress vibration; With the increasing demand for large-scale distributed control devices in China and the successful development of high-end CNC systems, the development of networked digital servo has become an urgent task.
