Run Tag Event Script from Button Press (Gateway and Project Scope)

I would like to put a button on the screen to manually fire the script that typically runs automatically based on a tag event.

Is there a way to manually call the tag event script directly from the tag?

Or, will I have to more-or-less copy paste and make adjustments for calling from the button script instead of the tag change script?

Place the script in a Script Library, then you can call it from both the Tag Event and a Button press.

I have the script in the library, but there are properties of the tag that I need to pass to the script.

You can read tag properties from a tag using

system.tag.readBlocking(['path/to/tag.property1Name','path/to/tag.property2Name'])

This project script calls a named query. Typically, it's from the gateway scope, so my named query call has extra parameters when calling from the button press (project/client) scope that is causing errors.

Any way to avoid this without adding an extra parameter to my project script?

I decided to just add an optional parameter to my project script, since that's the easiest solution. Default "clientScope" variable to 0 (false), and it can be provided as true when needed to call from the project scope.

This is the only way that I know of.

You can also use system.util.sendMessage to the gateway and let the gateway message handler call the library script. It will then be in gateway scope all of the time.
