What is a project event?

Create a project event to trigger an action for an entire project. Events created for a specific item, such as a graphic element, Add-On Graphic, or a screen, trigger an action only for that item. A project event triggers regardless of the screen or popup on the HMI device.
Project events execute commands on the HMI device after:
  • Evaluating an expression from false to true
  • Pressing a key
    TIP:
    You can use an external keyboard with the HMI device. The
    L1
     through
    L10
     keys listed when creating Key Press and Key Release events correspond with pressing
    Shift+F1
    through
    Shift+F10
    keys on an external keyboard. The
    R1
     through
    R10
     keys listed when creating Key Press and Key Release events correspond with pressing
    Ctrl+F1
     through
    Ctrl+F10
     on an external keyboard.
For example, use project events to display a specific screen or popup when a machine enters a specific state and needs operator attention. These events trigger automatically without operator intervention.
TIP:
A matching key press event for the currently displayed screen or graphic element with focus takes precedence over the project event.
Add one or more commands to a project event to execute those commands when the event triggers. Each event has a bindable
Enabled
property for evaluating the event. If the
Enable
property is false, the event is not evaluated and the commands of the event do not perform.
