Hi, I am using vijeo designer v 4.6.. Now in my HMI program i was supposed to change a screen whenever user switches from Manual mode to Auto mode..... In this case i want to do it with out touching the screen that means automatically tht screen trigger or screen change must happen.... I did this scenario in siemens HMI program.... I want to know whether it s possible in vijeo designer and if it can be how to perform the process.... Pls guide me... Thanks in Advance
