Show a popup in perspective on all clients if a value changes

Why do I use a tag change scrip on the tag vs the gateway? What is the difference between using one or the other?

This is what is showing up in my wrapper logs, added a few print statements inside the if statement which show up there but still not popping up on my sessions.

popupId = "O2Alarm"
viewPath = "Page/Popups/O2 Alarm Popup"  # insert your view path here
logger = system.util.getLogger("POPUP")
sessions = system.perspective.getSessionInfo()
for session in sessions:
	for pageId in session.pageIds:
		logger.info("{0} | {1}".format(session.id, pageId))

		if currentValue.value:
			print "Current value is:"
			print currentValue.value
			print popupId
			print viewPath
			system.perspective.openPopup(popupId, viewPath, sessionId=session.id, pageId=pageId)
		else:
			# note no viewPath arg
			system.perspective.closePopup(popupId, sessionId=session.id, pageId=pageId)

This is what I have for my code which is pretty much what you sent besides a few added print statements, not quite sure why my popup is not showing up.

cmallonee · June 27, 2022, 3:21pm

That logging looks very much like it should be working, and I even see a sessionId and pageId in the logging. That code worked for me and I’ve even verified that the space in the View path does not affect functionality. Are you positive you saved after creating the “Page/Popups/O2 Alarm Popup” file?

Evan_Rosonke · June 27, 2022, 3:26pm

I am positive that I had saved that file, everything else seems as it is working, strictly the popup is not showing up when enabling that tag.

cmallonee · June 27, 2022, 3:29pm

Remove the logging you put into place and place a new line of logging AFTER the popup functions are called. This will tell you whether or not the function is executing as expected. Are you looking at the browser session, or are you testing this in the Designer?

Evan_Rosonke · June 27, 2022, 3:36pm

Looking at it in the browser session and still have no popup, have tried changing value in designer as well as in studio 5000 to toggle the value.

Below is what happens in the logger when I place logger.info(“{0} | {1}” … inside of the if statement

No, don’t place the same logging, just put

logger.info("openPopup complete")

on the line following the openPopup function. I recommend removing your print statements, just to remove clutter. Also, always place any stacktraces within a code block (triple back-ticks) so that it can be easily parsed.

Also also, if you modify code and provide a new stacktrace, you should also provide the NEW code in a code-block, and it’s extra helpful if you can identify which line the error is referencing. In your case, leave a comment on what is line 16 in your code-block. If you don’t do this, then others trying to help you have to make guesses about which line you’ve made changes to, and what could possibly be triggering the error.

cmallonee · June 27, 2022, 3:53pm

When I run the following code:

def valueChanged(tag, tagPath, previousValue, currentValue, initialChange, missedEvents):
	popupId = "O2Alarm"
	viewPath = "Split"  # insert your view path here
	logger = system.util.getLogger("POPUP")
	sessions = system.perspective.getSessionInfo()
	for session in sessions:
		for pageId in session.pageIds:
			logger.info("{0} | {1}".format(session.id, pageId))
	
			if currentValue and currentValue.value:  # I added an additional safety check for first time use here
				system.perspective.openPopup(popupId, viewPath, sessionId=session.id, pageId=pageId)
				logger.info("openPopup complete")
			else:
				# note no viewPath arg
				system.perspective.closePopup(popupId, sessionId=session.id, pageId=pageId)

I get the following logging:

POPUP	27Jun2022 08:49:51	B9B1743A | Split
POPUP	27Jun2022 08:49:51	openPopup complete
POPUP	27Jun2022 08:49:51	f456b99d-af9d-4410-94ce-39aec47272c8 | 32a9092e

Which tells me that

the first page found was a browser session
the popup function executed as expected (and I verified a Popup was open)
A designer “page” was found (note the 8-digit identifier in use for the sessionId and View name in use for the pageId).
The openPopup function did not complete the second time through because the session was a Designer.

Evan_Rosonke · June 27, 2022, 4:13pm

Also, my line 14 was my previous line 16, I just removed white space from above.

Evan_Rosonke · June 27, 2022, 4:28pm

This is my wrapper log

This is my code
I am still not getting a popup in the browser session.

I am using the tag path from my designer and copying it from there, I assume that’s what I am supposed to use?

This is the path I am using

cmallonee · June 27, 2022, 4:36pm

In your browser session, please use the Application bar to locate the Page ID for your page.

Click the arrow icon in the bottom-right of the session:
Screen Shot 2022-06-27 at 9.33.42 AM

Click the button in the center of the bar:
Screen Shot 2022-06-27 at 9.33.49 AM

Click the STATUS button:
Screen Shot 2022-06-27 at 9.33.58 AM

locate the Page ID:
Screen Shot 2022-06-27 at 9.34.12 AM

If that Page ID value matches the pageId being logged (172301c6), then you’ll need to contact support because everything seems to be working exactly like it should.

Evan_Rosonke · June 27, 2022, 4:42pm

This is the session status

I do not believe my PageID matches, not sure how to fix that?

cmallonee · June 27, 2022, 4:47pm

That tells me you’re looking at a page from a different gateway. Do you see how even your Session ID does not match? If that session existed on the Gateway you’re interacting with then we would also see that session included in the logging.

Evan_Rosonke · June 27, 2022, 4:50pm

I do see that, How would I go about fixing that? I have the page inside my gateway that I am using, not sure why it is calling a different one? I had created it in another gateway on our server and copied it to the server I am trying to use it on, would that be the cause and if so how do I got about fixing it?

Alagumani_Kaliyaperu · September 3, 2022, 2:26pm

Hi I am also have the same requirement, i tried to follow the script as you discussed in above conversation, actually I am on learning stage i just started my career in Ignition last month so can you please share your latest script and if possible please share the step by step procedure to control the Popup by Boolean tag.

Thanks

jlandwerlen · September 3, 2022, 2:36pm

This post is really detailed, so if you are having problems please post what you have tried and the specific problems or errors you encounter, otherwise there isn’t much help that can be offered other than what is in this post.

If you are new to Ignition It’s highly recommended to complete IU before you do anything else.

Alagumani_Kaliyaperu · September 3, 2022, 2:57pm

![Designer|690x393](upload://7em7fihMkVU18wJE4f1kyA98A66.
Thanks for your reply. I am not sure about my PageId, Session.id. I have attached my script picture for your reference. also i am not sure where I have to write the script.

Alagumani_Kaliyaperu · September 3, 2022, 2:58pm

Its my Script

jlandwerlen · September 3, 2022, 3:19pm

When posting code, use preformatted text (hit the button with </>

Example code

What is view path for the popup you want to popup?
You place the code in value changed event of your tag, which appears from your screenshot as correct.

You don’t need to worry about PageId and SessionId as the code handles that for you. If you don’t understand sessions, pages, and views, then you need to start there and fully understand the concepts.

If you put the correct view path into the script it should work. The code posted worked for me.

Alagumani_Kaliyaperu · September 3, 2022, 3:53pm

Thanks for your support. If you don’t mind can get your popup working back for my reference. Since I am new to ignition so it will help to understand the concept.
