Hello,  
I am working on reverse engineering a previous Co-workers Ignition project when I came across a value change script he has on a tag:

`system.util.invokeAsynchronous(smart_interface.matrox.status.dataReady, args=[tagPath, currentValue])`

and I can not seem to figure out what it is doing. I looked it up in the manual and kind of get what the function is doing, but not fully. The manual makes it seem like “`smart_interface.matrox.status.dataReady`“ would be a function I could find, but I can not find it anywhere.

Would someone be able to explain it to me a little better?

Thanks!

Look in your gateway web UI to find the gateway scripting project setting. Open **that** project in the designer, and look in its project library scripts.

Tags don't belong to any project, and therefore have no access to a project library unless one project is designated to cover non-project scope. (Conversions from v7.9 would set this up for you with the content of the `shared.*` scripts.)
