Add an event command for navigation on the HMI device

Add an event command to navigate a screen or popup on the HMI device. Do this to open a screen, navigate screen history, open or close a popup, or open the Navigation menu on the HMI device.
Prerequisites
  • Create an event to trigger the command:
    • Touch press.
      Occurs when touching the item on the screen that is configured with the event.
    • Touch release.
       Occurs when releasing the item on the screen that is configured with the event.
    • Key press.
      Occurs when
      pressing the specified key.
    • Key release.
      Occurs when releasing the specified key.
To add an event command for navigation on the HMI device
    1. Select the graphic element configured with the touch or key event.
    2. In the
      Properties
      pane on the
      Events
      tab, select
      Add Command
      .
    Expand the
    Navigation
    category and select the command:
    • Navigate Backward.
       Navigates back in history to the screen opened using the
      Navigation
      menu or a
      Screen Navigate
       command.
    • Navigate Forward.
       Navigates forward in history to the screen opened using the
      Navigation
      menu or a
      Screen Navigate
       command.
      TIP:
      Logging off the HMI device erases the navigation history.
    • Show Navigation Menu.
       Opens the
      Navigation
      menu on the HMI device screen when the event occurs.
    • Popup Close.
      Closes the popup on the HMI device when the event occurs. Only one popup at a time can open on the HMI device.
    • Popup Open.
      In the
      Open Popup
       box, navigate to and select the popup the event is to open.
    • Screen Navigate.
      Opens the specified screen when the event occurs. In the
      Navigate To
       box, select the shortcut or screen that the event is to open.
      TIP:
      Tips:
      • If the selected screen or popup for a Screen Navigate or Popup Open command has a user-defined data type property, bind the value in the
        Property Configuration
         box to the user-defined data type property of the shortcut or popup. This passes the value to the screen or popup when it opens on the HMI device.
      • If a graphic element on the screen or popup to open for a Screen Navigate or Popup Open command has an aliased property with a value, the Screen Navigate command or Popup Open command can read the value from a referenced graphic element and apply it to the alias. In the
        Property Configuration
         box at the bottom of the command, enter the name of the graphic element and the property that has the value to apply to the aliased property. Use the format ElementName.PropertyName. When the event triggers, the graphic element on the screen or popup with the aliased property shows the property value of the graphic element that is referenced in the
        Property Configuration
         box. The
        Property Configuration
        box appears for the command only if there is an aliased property or user-defined property on the target screen or popup.
