title: Tag prefix Win CC
body: <p>I am busy with a C script in Siemens WinCC. 
  I would like to open a faceplate on in which I can open other faceplates. 
  Howerver, I would like to use the Tagprefix from the first faceplate in the second. Does anybody have an idea how I can give the tag prefix through? </p>
  
  <p>Thanks in advance!
