macro_command main()
short a,b
float c
GetData(a, "Local HMI", LW, 30, 1)
GetData(b, "Local HMI", LW, 31, 1)
c=a/b
SetData(c, "Local HMI", LW, 32, 1)

end macro_command





這樣對不對

放個圖片怎么就這么難

寫成下面這樣就可以了    之前沒把a,b換成浮點數，宏指令不支持



macro_command main()
short a,b
float a1,b1,c
GetData(a, "Local HMI", LW, 10, 1)
GetData(b, "Local HMI", LW, 11, 1)
a1=a
b1=b
c=a1/b1
SetData(c, "Local HMI", LW, 12, 1)
end macro_command
