Add an Add-On Graphic to a screen

Add an Add-On Graphic to a screen from either the Toolbox or the Project Explorer. Add no more than 500 elements on a screen. Each Add-On Graphic instance adds the number of elements contained in that Add-On Graphic toward the recommended limit of 500 elements. If there is an Add-On Graphic defined that contains 10 elements and that that Add-On Graphic appears 10 times on a screen, this accounts for 100 elements on the screen. After adding an Add-On Graphic to a screen, change its appearance and behavior by changing the properties of the Add-On Graphic, associating the Add-On Graphic with an animation or event, or binding the Add-On Graphic to a user-defined tag. Directly binding the definition of an Add-On Graphic to a controller tag is not allowed.
Prerequisites
  • Verify that the definition of the Add-On Graphic exists in the
    Assets > Add-On Graphics
    folder of the
    Project Explorer
    .
    TIP:
    Tips:
    • The
      Add-On Graphics
      folder contains two predefined Add-On Graphics to display, zoom, and navigate a PDF document on the HMI device:
      • PDF_Viewer_Landscape.
         Occupies the entire screen of an HMI device.
      • PDF_Viewer_Portrait.
         Occupies half of the screen of an HMI device.
    • The PDF_Viewer_Portrait Add-On Graphic is not available on six-inch or seven-inch HMI devices.
To add an Add-On Graphic to a screen
  1. In the
    Toolbox
    , expand the
    Add-On Graphic
     category.
  2. Drag or double-click the Add-On Graphic or press
    Enter
     when the Add-On Graphic is selected.
    The Add-On Graphic appears on the screen and links to the definition in the
    Add-On Graphics
     folder.
    TIP:
    Tips:
    • Double-clicking adds the Add-On Graphic to the center of the screen.
    • If a graphic element is selected on the screen when adding the Add-On Graphic, the Add-On Graphic is placed on top of the selected graphic element.
    • If the outline of an empty Add-On Graphic appears on the screen, the definition of the Add-On Graphic is empty. Add graphic elements to the Add-On Graphic by changing the definition of the Add-On Graphic. All instances of the Add-On Graphic update to display the contents of the Add-On Graphic.
    • Add an Add-On Graphic from a different project by copying and pasting the Add-On Graphic between the projects.
    • Search for a known name of the Add-On Graphic to add using the search feature of the
      Toolbox
      .
    • The name of each Add-On Graphic added to a screen is appended with a number that increments with each instance. For example, MyPlantMixer_002 indicates a second instance of the MyPlantMixer Add-On Graphic on a screen.
    • It is recommended to have no more than 200 Add-On Graphic definitions in a project.
    • To add an Add-On Graphic from the
      Project Explorer
      , drag the Add-On Graphic from the
      Assets > Add-On Graphics
       folder to the screen, or right-click the Add-On Graphic and select
      Add Add-On Graphic to (screen name)
      .
IMPORTANT:
  • Too much content on screens can result in the HMI device running out of memory. The
    Properties
    tab displays the size of the image. Use the predefined
    HMI Device
    screen to monitor memory usage. If the HMI device runs out of memory while running an application, the HMI device restarts and provides an error message indicating that an out-of-memory condition occurred.
  • If the computer running
    View Designer
     runs out of memory,
    View Designer
     shuts down and provides a message indicating that an out-of-memory condition occurred.
    View Designer
     retains the last saved version of the project.
