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控制系統(tǒng)為主要參考模式,采用填表的方式進(jìn)行控制組態(tài),用戶只需定義i / o條件、填寫具體的運(yùn)算變量名、邏輯變量名即可。本軟件為建模人員提供了一個(gè)友好的用戶界面,使建模人員在建模時(shí)不必對模塊內(nèi)部的控制、邏輯程序有很深的了解就可以方便的對其進(jìn)行編寫和修改,實(shí)時(shí)改變各邏輯和控制變量在數(shù)據(jù)庫里的值,參與運(yùn)行和調(diào)試,從而實(shí)現(xiàn)對機(jī)組的控制。因此,本組態(tài)軟件提供的這樣一個(gè)平臺,讓控制工程師能集中精力于控制回路及邏輯保護(hù)(包含電氣邏輯)的構(gòu)成,而不必拘泥于一些具體而煩瑣的程序操作。
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 在本課題中,采用填表的方式進(jìn)行控制組態(tài),用戶只需定義i / o條件、填寫具體的運(yùn)算變量名即可。本軟件為建模人員提供了一個(gè)友好的用戶界面,使建模人員在建模時(shí)不必對模塊內(nèi)部的控制、邏輯程序有很深的了解就可以方便的對其進(jìn)行編寫和修改,實(shí)時(shí)改變各邏輯和控制變量在數(shù)據(jù)庫里的值,參與運(yùn)行和調(diào)試,從而實(shí)現(xiàn)對系統(tǒng)的控制。因此,本組態(tài)軟件提供的這樣一個(gè)平臺,讓控制工程師能集中精力于控制回路的構(gòu)成,而不必拘泥于一些具體而煩瑣的程序操作。
