威綸通宏指令，使用while后，無(wú)法停止。


macro_command main()

bool a,b,c = 1 ,d = 0
int e

GetData(a,"HMI",LB,2,1)
GetData(b,"HMI",LB,3,1)

while (a == true and b == false)
  SetData(c,"HMI",LB,0,1)
  SetData(d,"HMI",LB,1,1)
  DELAY(1000)
  SetData(d,"HMI",LB,0,1)  
  SetData(C,"HMI",LB,1,1)
  DELAY(1000)
  if b == true then
  break
  end if
  wend
end macro_command

如樓上所說(shuō)，在while語(yǔ)句中間加“GetData(a,"HMI",LB,2,1)，GetData(b,"HMI",LB,3,1)”讓“a,b”保持刷新即可

while (a == true and b == false)
~~~
GetData(a,"HMI",LB,2,1)
GetData(b,"HMI",LB,3,1)
~~~
wend
