ActivateScreen by Tag in Script

11/12/2008 9:20 PM	Rate (0)
WilqU Posts: 7 Rating: (0)	Hi everyone! Can you help with this one? I'm using MP277 10" and WinCC flexible 2008. I'd like to type name of window in IOField and after click enter button I want to jump to that window. IOField is connected with string tag i.e ScreenChoiceTag. I know I can write a script and use If ... ElseIf... or Case... with ActivateScreen system function but I have 68 screens. I want to write something shorter like this: ActivateScreen ScreenChoiceTag,0 but it's wrong syntax. I can't use ScreenChoiceTag as a parameter here. Is it possible to do it in this way?

After the user enters the desired screen name into the I/O field have them push a button that calls a script with the following line. HmiRuntime.BaseScreenName = SmartTags("ScreenTag")
