1)系统程序存储区。在系统程序存储区中存放着相当于计算机操作系统的系统程序,

包括监控程序、管理程序、命令解释程序、功能子程序、系统诊断子程序等。由制造厂商

将其固化在EPROM中,用户不能直接存取。它和硬件一起决定了 该PLC的性能。

2)系统RAM存储区。系统RAM存储区包括I/O映像区以及各类软设备,如:逻辑

线圈、数据寄存器、计时器、计数器、变址寄存器、累加器等存储器。组态控制技术属于一种计算机控制技术。它是利用计算机监控某种设备使其按照控制要求工作。利用组态控制技术构成的计算机组态监控系统主要由被控对象、传感器、I/O接口、计算机及执行机构等部分组成。

本次实训是借助MCGS组态软件平台来完成组态监控系统人机界面制作和程序的设计的。MCGS(Monitor and Control Generated System, 通用监控系统)组态软件是北京昆仑通态软件公司研发的基于Window平台的,用于快速构造和生成上位机监控系统的组态软件系统。通过对现场数据的采集处理,以动画显示、报警处理、流程控制、报表输出等和多种方式向用户提供解决实际工程问题的开发平台。

由于是国人开发的软件,所以它是全中文的,很适合我们使用,还有它可提供近百种绘图工具和基本图符,快速构造图形界面,此外还提供上千个精美的图库元件及渐进色等多种

动画方式可以快速的构建精美的动画,它还支持温控曲、计划曲线、时实曲线、历史曲线、XY等多种工控曲线。之使用MCGS软件可以较快速的完成一个运行稳定、功能成熟、维护量小并且具备*水准的计算机监控控制系统的开发工作。下面我来介绍在使用MCGS组态软件来完成任务的详细过程及遇到的问题和解决的办法。

任务一 水泵运行控制

打开MCGS通用版组态软件,我们会看见5个部分,分别为主控窗口、设备窗口、用户窗口、实时数据库和运行策略。

首先我们先新建一个工程,将其命名为水泵控制系统并进行保存。

然后打开用户窗口完成相关图符的建立,老师在建工程时先建立了实时数据库,是因为对图符的控制属性有较清楚的认识,所以对于初学者来说,先画图符是*的选择。

(1)在用户窗口中新建一个窗口0,并将其重命名水泵运行控制,在动画窗口中用标签建立动画的标题“水泵控制”

(2)绘制水泵

在软件中,已经为我们提供了“对象原件库”我们可以在其中选择所要的原件,所以接下来添加一个“泵30”图符再确定,可以调节图符的大小,以至达到美观的效果

(3)在泵下面添加两个“按钮”分别将名称改为“启动”和“停止”也可以双击来改变按钮的背景颜色。

(4)因为要展示停止和启动时的状态所以再添加两个指示灯,为了更为清楚的展现启动和停止的状态,也可以自己改造一个指示灯,其改造方法为先用一个库提供的指示灯作为改造对象先分解单元在将*前面的图符拖走,将底层的图符分解图符再改变其颜色和添加一个“可见度”属性并在表达式里填入@开关量,然后再对另一只指示灯做相关属性的设置。

(5)为了显示时间我们再添加两个按钮分别为“定时器启动”和“定时器复位”再添加 两个标签分别为控制“计时时间”和“时间到”。

(6)添加四个输入框将其属性设置为数值型,

(7)现在我们来进行实时数据库里相关数据的添加,分别为 水泵、启动、复位、定时器启动、定时器复位都是开关量,而“计时时间”和“时间到”为数值型。

(8)实时数据建立完成后,再进行用户窗口里图符的相关表达式的关联,由于要有时间控制所以在运行策略里我们要添加一个定时器,和一个脚本程序,在定时器属性里设置时间值为35秒,在脚本程序里用IF-THEN语句来编写控制程序。记住要用EXIT来划分步骤,在*要进入运行环境测试前,应调节循环策略的属性,将定时循环时间改为200s。

This training is d on the MCGS configuration software platform to complete the man-machine interface production and program design of the configuration monitoring system. MCGS (monitor and Control Generated System) configuration software is a configuration software system d on the window platform developed by Beijing Kunlun Tongtai Software Co., Ltd., which is used to quickly construct and generate the upper computer monitoring system. Through the collection and processing of on-site data, the development platform for solving practical engineering problems is provided to users by means of animation display, alarm processing, process control, report output, etc.



Because it is a software developed by Chinese people, it is all Chinese and very suitable for our use. In addition, it can provide nearly 100 kinds of drawing tools and basic symbols, quickly construct graphical interfaces, and also provide thousands of exquisite library elements and progressive colors



The animation mode can quickly build beautiful animation, and it also supports temperature control curve, plan curve, time real curve, history curve, XY and other industrial control curves. In short, MCGS software can quickly complete the development of a computer monitoring and control system with stable operation, mature function, small maintenance and professional level. Next, I will introduce the detailed process of using MCGS configuration software to complete the task, the problems encountered and the solutions.



Task 1: pump operation control



Open the MCGS general configuration software, and we will see five parts, namely, main control window, equipment window, user window, real-time data and operation strategy.



First, we will create a new project, name it the pump control system and save it.



Then open the user window to complete the establishment of relevant symbols. The teacher first established a real-time data when building the project, because he has a clear understanding of the control attributes of symbols, so for beginners, drawing symbols first is the first choice.



(1) Create a new window 0 in the user window, rename it to the pump operation control, and create an animated title "pump control" with a label in the animation window



(2) Draw pump



In the software, we have been provided with an " original library" in which we can select the original we want, so next, we add a "pump 30" icon and confirm it. The size of the icon can be adjusted to achieve a beautiful effect



(3) Add two "buttons" under the pump to change the name to "start" and "stop" respectively. You can also double-click to change the background color of the button.



(4) Two more indicator lights are added to show the status of stop and start. In order to show the status of start and stop more clearly, you can also transform an indicator light yourself. The transformation method is to first use the indicator light provided by a library as the transformation , first decompose the unit, and then drag the first icon away, Break down the bottom icon, change its color, add a "visibility" attribute and fill in the with @ switch value, and then set the related attributes of the other indicator light.
