I am wanting to create a popup window for a few alarms. The maintenance staff has asked that when an alarm goes off that a pop up screen will appear. Is there a way to make a popup come on based on a tag value rather then a button?

Thanks

Yes, you would use a client tag change event script, subscribed to the desired tag.

I have written the code on the root container as a custom property but it does not work. Any ideas?

```python
def Popup(self):
	"""
	Arguments:
		self: A reference to the component instance this method is invoked on. This argument
		  is automatic and should not be specified when invoking this method.
	"""
selectONE = system.tag.read("[default]VIB-01/Alarm").value

if selectONE == 1:
	system.nav.openWindow('Generators')
	system.nav.centerWindow('Generators')
else:
	system.nav.closeWindow('Generators')

```

I have got it to work using a client tag however I do not want it to open when the tag turns to 0. As of now any change in the tag value causes the popup to happen.

Thoughts?

You'll have to check `newValue.value != 0` in your tag change script, as the script gets called for any change like you've seen.

P.S. I also recommend checking `initialChange`, which is `True` when the tag 'change' is due to a new subscription (client start or project update), and `newValue.quality.good`, since if the tag quality changes that also triggers a change.

I have the code as follows. Where should I make the changes?

```python
def valueChanged(tag, tagPath, previousValue, currentValue, initialChange, missedEvents):

		system.nav.openWindow('Generators')
		system.nav.centerWindow('Generators')

```

```python
type or paste code here

```

My mistake, `newValue` is for Gateway tag change event scripts.

```python
def valueChanged(tag, tagPath, previousValue, currentValue, initialChange, missedEvents):

	if (not initialChange) and currentValue.quality.good and currentValue.value != 0:
		system.nav.openWindow('Generators')
		system.nav.centerWindow('Generators')

```
