        This function specifies if an elementary symbol is active or inactive.
      - hook_<libraryPrefix>_faceplateHeadline()
        This function specifies the text for the header of a faceplate.
      - hook_<libraryPrefix>_faceplateWindowTitle()
        This function queries the text of the faceplate window title of the referenced data point.
      - hook_<libraryPrefix>_hasUserAuthorization()
        This function determines whether a certain user has the authorization to change the value of a data point element.
      - hook_<libraryPrefix>_highlightElementarySymbol()
        This function determines whether an elementary symbol is highlighted.
      - hook_<libraryPrefix>_namingFaceplateTabs()
        This function determines the titles for the tabs in a faceplate.
      - hook_<libraryPrefix>_objectTooltip()
        This function determines the tool tip text of a symbol.
      - hook_<libraryPrefix>_openFaceplate()
        This function opens the faceplate of a symbol.
      - hook_<libraryPrefix>_projectFillPopUpMenu()
        This function configures the context menu of a symbol and elementary symbols of a faceplate.

hook_<libraryPrefix>_faceplateHeadline()

This function specifies the text for the header of a faceplate.

Synopsis

langString hook_<libraryPrefix>_faceplateHeadline(string sDp);

Parameters


Parameter	Description
sDp	Data point name to which the symbol references.

Return Value

Header text of a faceplate.

Description

This function specifies the text for the header of a faceplate. By default the description of the data point is used as a text for the header.

You can find the function in the stdlib_hook_project.ctl under wincc_oa_path/Stdlib_3.20/scripts/libs/

langString hook_faceplateHeadline(string sDp)
{
  langString lsHeadline = hook_getFaceplateHeadline(sDp);
  if ( lsHeadline == "" ) lsHeadline = dpGetDescription(sDp);
  return lsHeadline;
}
