Description
Check whether one of the cases below applies.

  • In a picture, faceplates were not incorporated as OLE Control, but with the dynamic wizard "Screen selection via measuring point". In this case the messages of these faceplates are not forwarded to the group display in the overview area.
    Remedy
    Insert a group display into the picture for each faceplate. Link the "Group Value" property of each group display directly to the EventState tag of the measuring points that are connected to the faceplates. You can switch the group display to be hidden by way of the "View" property. Save the "Picture Tree Manager" to complete configuration of the group displays.
     
  • The messages from pictures that are at a lower level than others in the "Picture Tree Manager" are not put through to the next highest level automatically.
    Remedy
    Place a group display in the higher level picture. Link the group display with the lower level picture using the dynamic wizard "Link group display with picture". You can switch the group display to be hidden by way of the "View" property. Save the "Picture Tree Manager" to complete configuration of the group displays.
     
  • If you have inserted faceplates or group displays into a picture, their messages are displayed in the overview area only if the "Picture Tree Manager" has been saved.
    Remedy
    Deactivate WinCC and open the "Picture Tree Manager". In the "Tools" menu you must enable the "Recalculate entire group display hierarchy when saving" option. Now save the "Picture Tree Manager". If there are still no messages displayed in the overview area, close and re-open WinCC.
