What is an event?

An event is something that occurs to trigger an action. Events trigger either manually or automatically by the system. Events trigger by:
  • Button Behavior
    . Touch or release a button or key on the HMI device, or configure a graphic element or Add-On Graphic with typical button behaviors.
  • Touch Press and Touch Release
    .
    Touch or release a graphic element, Add-On Graphic, screen, popup, or System Banner on the HMI device.
  • Key Press and Key Release
    .
    Touch or release a key on the HMI device keypad or an external keyboard.
  • State Enter and State Exit
    .
    Perform an event when a graphic element or Add-On Graphic transitions
    into or out of a selected state. For example, perform the event when the value of a tag in the controller changes from 50 to 100.
When an event triggers, it performs an event to:
  • Change the state of a graphic element. An event can apply the next or previous state in an indicated state table configured in
    Studio 5000
    View Designer
    . An event can change the appearance of a button to a previous red state or to the next green state.
  • Log on or off the project.
  • Open a specific screen or navigate to a previous or next screen in the navigation history.
  • Open or close a popup.
  • Open the
    Navigation menu
    .
  • Increment the data value of a tag with a value or expression configured in
    Studio 5000
    View Designer
    .
  • Toggle a selected tag value between True and False.
  • Change the selected tag value by a value or expression specified in
    Studio 5000
    View Designer
    .
  • Change the language displayed on the HMI device.
  • Export a data log.
To identify the events configured for the application, contact the HMI designer.
