Therefore it comes true the on - line adjusting , real - time control and so on . it sames as real locale . the software of logic protect ( include electric logic ) and control includes some usual algebraic and operation model of thermal control and logic operation of logic protect . it adopts foxboro ' s dcs as a example , so we configuration via filling table , user only define i / o condition , fill certain operation variable , and name logic variable . the software offers a friendly user ' s interface , personnel can compile and modify the control and logic program , change the value of logic and control variable conveniently , attach themselves to run , debug and control the set , not need to know about the inside of the old programs deeply . so the configuration software offer a flat that control engineer can attend to the structure of control loop and logic protect ( include electric logic ) , not but to handle complicated program 它以foxboro的dcs控制系统为主要参考模式,采用填表的方式进行控制组态,用户只需定义i / o条件、填写具体的运算变量名、逻辑变量名即可。本软件为建模人员提供了一个友好的用户界面,使建模人员在建模时不必对模块内部的控制、逻辑程序有很深的了解就可以方便的对其进行编写和修改,实时改变各逻辑和控制变量在数据库里的值,参与运行和调试,从而实现对机组的控制。因此,本组态软件提供的这样一个平台,让控制工程师能集中精力于控制回路及逻辑保护(包含电气逻辑)的构成,而不必拘泥于一些具体而烦琐的程序操作。
The dcs of i / a series is regarded as main reference object , and the control is separated from model . and the configuration of control is operatised at administration system , not to be added into model , not to build control sound code also . therefore it realizes on - line adjusting , real - time control and so on . users configurate by filling table . they only define i / o condition , fill certain operation variable , and name logic variable . the software offers a friendly user ' s interface , so personnel can compile and modify the control and logic program , change the value of logic and control variable conveniently , attach themselves to run , debug and control the system , not need to know the programs deeply . so the configuration software offer a flat that control engineers can attend to control loop , not to give their attention to the complicated program 在本课题中,采用填表的方式进行控制组态,用户只需定义i / o条件、填写具体的运算变量名即可。本软件为建模人员提供了一个友好的用户界面,使建模人员在建模时不必对模块内部的控制、逻辑程序有很深的了解就可以方便的对其进行编写和修改,实时改变各逻辑和控制变量在数据库里的值,参与运行和调试,从而实现对系统的控制。因此,本组态软件提供的这样一个平台,让控制工程师能集中精力于控制回路的构成,而不必拘泥于一些具体而烦琐的程序操作。
A rectangular diagram of a logic function of variables drawn with overlapping sub - rectangles such that each intersection of overlapping rectangles represents a unique combination of the logic variables and such that an intersection is shown for all combinations 一种多变量逻辑函数(求值用)的方格图,横行表示一组变量(与取值) ,纵向表示另一组变量(与取值) ,重迭(相交)的方格表示若干逻辑变量的一种唯一的组合(与取值) ,而且表示了所有可能的逻辑变量的组合(与取值) 。
