PLC And Software Configuration

Controlling System Based on PLC

Programmable Logic Controllers (PLC), a computing device invented by Richard E. Morley in 1968, have been widely used in industry including manufacturing systems, transportation systems, chemical process facilities, and many others. At that time, the PLC replaced the hardwired logic with soft-wired logic or so-called relay ladder logic (RLL), a programming language visually resembling the hardwired logic, and reduced thereby the configuration time from 6 months down to 6 days [Moody and Morley, 1999].

Although PC based control has started to come into place, PLC based control will remain the technique to which the majority of industrial applications will adhere due to its higher performance, lower price, and superior reliability in harsh environments. Moreover, according to a study on the PLC market of Frost and Sullivan [1995], an increase of the annual sales volume to 15 million PLCs per year with the hardware value of more than 8 billion US dollars has been predicted, though the prices of computing hardware is steadily dropping. The inventor of the PLC, Richard E Morley, fairly considers the PLC market as a 5-billion industry at the present time.

With microelectronics and computer technology is developing rapidly, PLC (controller can be programmed) in the field of industrial control within very broad application. PLC is a digital computer-based technology, specifically for the industrial application environment designed electronic control device It uses programmable memory, and to control all types of mechanical and electrical equipment and integrated production process

With enterprises of high flexibility, high efficiency requirements, people in the face of larger and more complex production labor, not only wasting time and effort, more than it gains. Therefore, the automatic prototyping system and the emergence of widely used as a historical necessity. Molding equipment and computer technology and intelligence technology combining intelligent material molding equipment is the future development direction of the main

PLC automatic control prototyping system to replace the manual workshop. serves industrial control systems for the open and fast requirements, It can also satisfy users

stability and reliability requirements. The use of automated prototyping technology to be effective for customers to lower production costs, improve production efficiency and achieve revenue growth

the background of Software Configuration

"Configuration" with the concept of a distributed control system's distributed control ystem listed dcs) began to emerge before the vast majority of the production process automation technology officer known. In the industrial control and technological development and application process, pc (IPC) compared to the previous system pc exclusive technology to maintain a relatively fast pace of development, a variety of related technical maturing; Construction pc from the industrial control system pc software and hardware resources-rich, software interoperability between the strong; pc-based control system pc technology to industrial control the infiltration. Configuration Software occupy a very special and important place.

Configuration Software refers to data acquisition and process control of the specialized software, They are in hmi Control System (man-machine interface software. human machine interface) concept. Configuration software is a user can quickly establish their own hmi software tools, or development environment. In the configuration software, industrial users through the manual or authorized third parties to prepare hmi application Development of long hours, low efficiency, low reliability; or purchase a dedicated system scada industrial, communications and networking, open data interface equipment for i/o the broad support it has become the main content, as technology develops, SCADA will continue to be given new content. Usually closed system, the choice for a small, are often unable to meet the demand, it is difficult to external data interface, upgrades and new features have been severely curtailed. The emergence of configuration software, users from the plight of these people to extricate themselves, and to use the configuration software functions, Construction of a most suitable for their application. With its rapid development,

real-time database, real-time control, a control layer software platform and development environment use flexible configuration, to provide users with rapid construction of industrial control system monitoring functions. General levels of software tools.Configuration software should be able to support all kinds of industrial equipment and common communication protocol, normally should provide distributed data management and network functionality.Corresponding to the original and easy to

learn and use, can easily get technical support.With the relatively low cost of ownership; The advantages become more and more obvious.

Configuration Software Development in China and overseas, mainly Products Configuration software products in the early 1980s, and in the late 1980s entered China. But in the mid-1990s and before, configurable software application in China is not universal. First, there are roughly the following : ①domestic users still lack the understanding of the configuration software, the project configuration software is not the budget, or prefer to become part of the human and material resources for specific projects so long cycle of the PC cumbersome programming, instead configuration software; ②a very long time, the domestic software user awareness is not yet strong, Faced with the imports are expensive software (early multi-configuration software development for foreign manufacturers), Few users are willing to buy genuine. ③time domestic industrial automation and information.

With industrial control systems mis (Management Information management information system) and cims (computer integrated computer manufa cturing system) the large-scale application, which requires industrialized site for the production, operation, decision to provide more detailed and in-depth data, in order to optimize the production and operation of all aspects. Therefore, in 1995, the configuration software applications in China are gradually being universal. Now, several of the configuration software were introduced. Integrated manufacturing systems, and applications in depth, in the face of larger, more complex control of the control system, People come to realize that the original PC program development mode. The project is time-consuming effort, it stopped, and the technology level is not high, Configuration software for large-scale applications, a large number of data acquisition, control, can be processed and the results required for the management of the generated data, these requirements have not fully formed.

Programmable logic controller A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or lighting fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result. 1.History The PLC was invented in response to the needs of the American automotive manufacturing industry. Programmable logic controllers were initially adopted by the automotive industry where software revision replaced the re-wiring of hard-wired control panels when production models changed. Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles was accomplished using hundreds or thousands of relays, cam timers, and drum sequencers and dedicated closed-loop controllers. The process for updating such facilities for the yearly model change-over was very time consuming and expensive, as electricians needed to individually rewire each and every relay. In 1968 GM Hydramatic (the automatic transmission division of General Motors) issued a request for proposal for an electronic replacement for hard-wired relay systems. The winning proposal came from Bedford Associates of Bedford, Massachusetts. The first PLC, designated the 084 because it was Bedford Associates' eighty-fourth project, was the result. Bedford Associates started a new company dedicated to developing, manufacturing, selling, and servicing this new product: Modicon, which stood for MOdular DIgital CONtroller. One of the people who worked on that project was Dick Morley, who is considered to be the "father" of the PLC. The Modicon brand was sold in 1977 to Gould Electronics, and later acquired by German Company AEG and then by French Schneider Electric, the current owner. One of the very first 084 models built is now on display at Modicon's headquarters in North Andover, Massachusetts. It was presented to Modicon by GM, when the unit was retired after nearly twenty years of uninterrupted service. Modicon used the 84

1 Bit Logic Instructions 1.1 Overview of Bit Logic Instructions 1.1.1 Description Bit logic instructions work with two digits, 1 and 0. These two digits form the base of a number system called the binary system. The two digits 1 and 0 are called binary digits or bits. In the world of contacts and coils, a 1 indicates activated or energized, and a 0 indicates not activated or not energized. The bit logic instructions interpret signal states of 1 and 0 and combine them according to Boolean logic. These combinations produce a result of 1 or 0 that is called the “result of logic operation” (RLO). The logic operations that are triggered by the bit logic instructions perform a variety of functions. There are bit logic instructions to perform the following functions: ---| |--- Normally Open Contact (Address) ---| / |--- Normally Closed Contact (Address) ---(SAVE) Save RLO into BR Memory XOR Bit Exclusive OR ---( ) Output Coil ---( # )--- Midline Output ---|NOT|--- Invert Power Flow The following instructions react to an RLO of 1: ---( S ) Set Coil ---( R ) Reset Coil SR Set-Reset Flip Flop RS Reset-Set Flip Flop Other instructions react to a positive or negative edge transition to perform the following functions: ---(N)--- Negative RLO Edge Detection ---(P)--- Positive RLO Edge Detection NEG Address Negative Edge Detection POS Address Positive Edge Detection

译文 可编程逻辑控制器技术 引言 PLC(可编程逻辑控制器)实际是一个工业控制系统(近来我们看到更多的是用处理器来取代微控制器),在软件和硬件都配备的条件下,适合应用于工业环境。PLC的发明是相当必要的,它代替了传统的依靠由继电接触器电路来控制电机。PLC的工作原理是根据它的输入信号和工作状态来确定输出。用户通常是通过软件或编程输入一个程序,来输出所需要的结果。 如图8-1所示,PLC是由典型的黑色构件组成。特别需要注意的是它的输入和输出,因为在这些模块上,工业环境会给CPU一个输入线,所以很有必要将CPU模块隔离以保护其免遭有害的影响。程序单元通常是用计算机来编写程序(一般是梯形图)。 1.1 CPU的中央处理单元 中央处理单元(CPU)是一个PLC的主控制器。一般CPU本身是一个微控制器。通常这些都是8位微控制器,如8051 ,现在的这些是16位和32位微控制器。潜规则是,你会发现用在PLC控制器上的微控制器多数是由日本生产的日立和富士通,欧洲的西门子控制器,和美国的摩托罗拉微控制器。CPU也负责通讯,与PLC控制器的其它部分相互联系,如程序执行,内存操作,监督输入和设置输出。PLC控制器拥有复杂的程序用于内存检查,以确保PLC内存不被损坏(内存检查是为了安全原因而作出的)。一般来说,CPU 单元多数用来检查PLC控制器本身,所以有可能出现的错误很早就会被发现。你可以简单地看任何PLC控制器,查看错误信号在发光二极管上的种种指示形式。 1.2 内存 系统内存(今天主要是在FLASH技术上实现)用于一台PLC的过程控制系统。除了这个操作系统它还包含用户程序将梯形图翻译成二进制的形式。 FLASH存储器的内容仅在用户程序改变下可以改变。PLC控制器较早被用来代替闪存,EPROM存储器代替了那些只能依靠紫外线灯等擦除内存并依靠程序员来编程的FLASH存储器。在FLASH技术的作用下这个过程被大大的缩短了。重组程序内存通过程序中的串行通讯用于应用程序开发。使用内存被划分成多个具有特殊功能的模块。存储器某些部分用来存储输入状态和输出状态。一个输入信号的实际状态是用1或0存储在一个特定的存储位。每一个输入信号和输出信号在内存里都有一个位与之相对应。内存的其他部分用来存储用户程序中使用的变量以及变量的内容。例如,定时器的值和计数器的值都将被存储在这部分内存里。 1.3 PLC控制器的编程 PLC控制器可以通过计算机(常用的方式)进行编程,还可以通过手动编程器(控制台)编程。这实际上意味着如果你有需要的编程软件那么每个PLC控制器都可以通过计算机进行编程。今天的传输计算机是非常适合在工厂对PLC控制器进行编程的。这对工业有着非常重要的意义。一旦系统被刷新,重新读取正确的程序到PLC就很重要。还可以定期检查PLC中的程序是否改变了。这有助于避免在工厂车间发生危险状况(部分汽车制造商建立了通信网络,定期检查项目中的PLC控制器,以确保执行的程序是正确的)。

第6章指令表、顺序结构图和结构文本的程序设计方法本章继续接着上一章讨论另外几种标准编程语言,例如,指令表(IL)、顺序结构图(SFC)和结构文本(ST)。 6.1指令表 指令表是一种采用文本形式进行梯形图程序设计的编程方法。指令表的程序由一系列的指令组成,每条指令占一行。程序指令由操作码及的一个至多个操作数组成,执行对象是操作码。梯形图中操作码被看作梯形图的构元素。每条指令都可以使用或更改存在记忆寄存器中的信息。为此,使用了助记符代码,每个代码对应一个操作码梯形图元素。尽管标准IEC 1131-3已经被提出并广泛使用,但是不同制造商使用的指令一定程度上并不一样。表6.1给出一些厂家所使用的指令,及本章所提议的标准指令(后面章节将讲述指令的其他功能。)下面给出使用IEC 113-1标准操作码的例子: LD A(*加载A*) AND B (*与B*) ST Q (*存储结果Q,输出Q*) 在程序的第一行,LD是操作码,A是操作数,在程序末尾括号中*之间的内容是评论,解释这行指令的作用,它是PLC指令的一部分。LD A这条指令表示将A加载至寄存器中,在之后的操作中可以调用它。第二行是A与B的布尔运算中的与操作。最后一行是将结果存储在Q中,即向Q输出。 标号可以用来标识不同的进入程序的入口,在程序跳转时十分有用。标号在指令的前面被冒号分隔开。因此有: PUMP_OK : LD C (*加载C*) 在程序之前面有一条指令,如果某个特殊的条件满足,那么程序就跳转执行PUMP_OK。 采用IEC 113-1 标准的操作码,在值后面加上字符N表示取反。例如:LD A (*加载A*) ANDN B (*AND NOT B*) 其中,ANDN操作把梯形图触点先“与”后“取反”。 6.1.1梯形图程序设计及指令表 下面看看梯形图的条件,当一个梯级开始工作,必须要使用一个“开始梯级

变频器在PLC的外文文献翻译

变频器在供水控制系统的应用 目前,在水位控制中有很大一部分水泵电机是不变速拖动系统,不变速电机的电能大多消耗在适应供水量的变化而频繁的开停水泵中。这样不但使电机工作在低效区、减短电机的使用寿命,而且电机的频繁开停使设备故障率很高,导致水资源严重浪费,系统的维护、维修工作量较大。 随着高位生活用水和工业用水逐渐增多,传统的控制方法已经落后。原先用人工进行水位控制,由于无法每时每刻对水位进行准确的定位监测,很难准确控制水泵的起停;使用浮标或机械等水位控制装置使供水状况有了一些改变,但由于机械装置的故障多,可靠性差,给维修带来很大的麻烦。 变频技术以其在节能与恒压方面的优越性能可以解决水压控制系统存在的以上问题。考虑选用单片机或PLC与变频器结合为核心构成的系统都能达到较好的控制效果。但在软件设计上,PLC比单片机的编程更简洁、直观;从硬件接口考虑,单片机电路稍微复杂一些;从经济方面考虑,由于PLC工艺的日渐成熟,小型PLC的成本与单片机相差无几,由于要根据现场情况调整系统参数,PLC的软件中时间参数的调整更简单,这样更有利于售后服务人员掌握。基于以上原因,选用了OMRON的CPM1系列PLC与ABB的变频器作为控制核心,再加上PSW7调节器与WSP300压力变送器,控制效果非常好,软件设计简单,硬件接口简易可行、可靠性高,整个系统的性价比非常高。 在供水系统中引进变频器结合小型PLC技术,不仅改变传统用阀门控制水量多少,而且在节能、恒压控制等方面均有非常好的效果,本文介绍了变频器--PLC调控技术在水泵控制中的应用。 控制系统用一台变频器可以带三台水泵,每台水泵既可以工作在常规工频泵模式,也可以工作在变频泵模式。每台泵只能处于变频或工频其中一种工作模式,通过两个继电器互锁保证它的安全与可靠。系统的结构如图一所示,利用安置在的生活用水中的压力变送器将水的压力信号传输到调节器,根据与调节器的设定值和报警上下限比较,送信号给PLC与变频器,系统的起停泵分别由调节器的压力下限信号和变频器的频率下限信号决定,假如压力低,调节器给PLC一个压力下限信号,PLC启动变频器,并使一号泵处于变频工作状态,输出的频率逐渐增大,经过一段时间的调节,如压力还低,这时,PLC让一号泵处于工频状态工作,使二号泵处于变频工作状态泵,如压力还低,则让二号泵处于工频状态工作,使三号泵处于变频工作状态,如此类推。当压力达到调节器上限报警值时,调节器输出降低,变频器频率降低,低到频率下限设定值,这时变频器给出一个频率下限信号给PLC,PLC根据先启先停的原则控制泵的运行顺序,例如,PLC 收到频率下限信号时,系统中泵的状态是一号工频,二号工频,三号变频,这时一号泵最先启动,所以先停,接着如压力还高,则停二号泵。系统采用了每次都进行低速启动,高速运行以提高运行效率。
