Global Events

Global events are project-level events that are always active regardless of which screen is being displayed. On the contrary, screen events are only active when their associated screen is being displayed.

Global Event Types

There are 4 available global event types:

  • Project Startup Event : This event occurs when the project is first executed.
  • Timer Event: This event occurs periodically while the project is running.
  • Device Event: This event occurs when data in a device's memory meets a specified condition.
  • Expression Event: This event occurs when a variable or expression evaluates to a specified condition.
