From TiA Portal V19 Update 2, a new parameter input has been added when using a Script on a Screen Object.

export async function Test_Left_Trigger(item, triggerDataSet) {

    ...
}

I can't find proper information on this topic. What data type is triggerDataSet? If it's an object, which properties are available?

The last Update Readme reports the following sentence, but the new parameters is called TriggerTags:

unknown user

Trigger tag in scripts
When you use a trigger tag to trigger a script in a screen object or a scheduled task, the
"TriggerTags" parameter is added to the function.
The "TriggerTags" parameter contains a collection of all configured trigger tags with the
following attributes of the tags:
• .Name
• .HasChanged
• .Value
• .QualityCode
• .TimeStamp
You can access the trigger tags and the respective attributes directly from the collection
without explicitly reading out the tags via ".Read()".
If you want to transfer user data type elements to the "TriggerTags" parameter, contact
Siemens Online Support.

Thanks.

Hi everyone,

I was looking for that also.

There is some explanation in a Siemens documentation you can download from here
