功能：觸摸屏用戶注銷，觸摸屏界面自動(dòng)切換到 窗口10
要實(shí)現(xiàn)這個(gè)功能 用宏指令怎么寫，那位朋友會(huì)宏指令

運(yùn)行不起來(lái)

主要是想學(xué)學(xué)，怎么使用宏指令

我搞定了，原來(lái)是要配合PLC控制功能才能實(shí)現(xiàn)
macro_command main()
int b=0
int c=0
GetData(b, "Local HMI", Lw, 9220, 1)
if b == 0 then
c=10
SetData(c, "Local HMI", LW, 0, 1)
else
c=0
SetData(c, "Local HMI", LW, 0, 1)
end if

end macro_command

授人與魚不如授人與漁，我只前只提供思路呀

版本太高了，打不開(kāi)啊

macro_command main()
char UserID[12]
bool ON = true,OFF=false
int UserID_len,lw300
short StarID = 10
StringGet(UserID[0], "Local HMI", LW, 10754, 12)
GetData(lw300, "Local HMI", LW, 300, 1)
UserID_len = StringLength(UserID[0])
SetData(UserID_len, "Local HMI", LW, 500, 1)
if UserID_len == 0 and lw300 <> 10 then
    SetData(StarID, "Local HMI", LW, 200, 1)
else
    SetData(lw300, "Local HMI", LW, 200, 1)    
end if

end macro_command

這條讀取LW300數(shù)據(jù)做什么啊，沒(méi)有看到上面作用啊
GetData(lw300, "Local HMI", LW, 300, 1)
