我目前在用維倫mt6070hi的想實(shí)現(xiàn)如下功能數(shù)據(jù)自動(dòng)更新功能， 但計(jì)數(shù)器超過(guò)數(shù)值時(shí)自動(dòng)將菜單更新。
指令如下：
macro_command main(  )
short CurrentOrder
short CurrentLength
short CurrentNumber
short AwaitOrder
short AwaitLength
short AwaitNumber
short feipin
short ActualCut
short SetCut
short n=0
short x=9
bool L
int  m

GetData(feipin, "Danfoss FC Series", Parameter, 1912, 1)  
GetData(SetCut, "Danfoss FC Series", Parameter, 1901, 1)
GetData(ActualCut, "Danfoss FC Series", Parameter, 1905, 1)
  
GetData(AwaitOrder ,"Local HMI", LW ,8002,1)
GetData(AwaitLength ,"Local HMI", LW ,8000,1)
GetData(AwaitNumber ,"Local HMI", LW ,8001,1)  
if ActualCut>=SetCut+ feipin then  
CurrentOrder=AwaitOrder
CurrentLength=AwaitLength
CurrentNumber=AwaitNumber
  
SetData(CurrentOrder, "Danfoss FC Series", Parameter, 1910, 1)    
SetData(CurrentLength, "Danfoss FC Series", Parameter, 1900, 1)
SetData(CurrentNumber, "Danfoss FC Series", Parameter, 1901, 1)
end if
end macro_command

但此時(shí)發(fā)現(xiàn)只有在滿足ActualCut>=SetCut+ feipin 時(shí)，在使用while........wend 時(shí)發(fā)現(xiàn)不能自動(dòng)更新數(shù)據(jù)， 手動(dòng)可以觸發(fā)數(shù)據(jù)更新， 但后面有對(duì)應(yīng)數(shù)據(jù)輸入，在不滿足ActualCut>=SetCut+ feipin 的條件下自動(dòng)更新數(shù)據(jù)
跪求各位大俠指點(diǎn)。
