How to Close a Perspective Popup Asynchronously After a Delay in Ignition?

Transistor · January 5, 2025, 5:07pm

In Project Browser, select the root of your view.
In Perspective Property Editor scroll down to CUSTOM.
Create a new custom property startTime.
- Create an expression binding on startTime with the expression, now(0). This will fire once when the popup opens and save the current timestamp in the custom property.
Create a second tag, timeout.
- Add an expression binding,
  (now(1000) - {this.custom.startTime}) > 5000
  This will evaluate every 1000 ms and will return true when the popup has been open for 5000 ms.
Right-click on custom.timeout and select Edit Change Script. Add the script,

def valueChanged(self, previousValue, currentValue, origin, missedEvents):
	if currentValue.value:
		system.perspective.closePopup("")

Tips:
now(0) → Runs once on load.
now() → Runs at the default scan rate - typically 1000 ms.
now(4321) → Runs every 4321 ms.
