功能选择中有—参数设置切换界面  这时可以有用户设置的密码  这个在威纶通触摸屏中怎么做啊？？、哪位大师教一下啊

用宏来做：
macro_command main()
int Pass,DataEn=0
short Page
bool  ON=true,Off=false
GetData(Pass, "Local HMI", LW, 2, 1)
if pass==123456 then
   page=10
   SetData(page, "Local HMI", LW, 20, 1)
else
  SetData(ON, "Local HMI", LB, 1, 1)
  end if
  SetData(Off, "Local HMI", LB, 0, 1)
  SetData(DataEn, "Local HMI", LW, 2, 1)

end macro_command
