Hi,
The ID of a parameter which create a new record is called Event IO ID in that record.
Normally device creating records as per data acquisition settings,in this records event IO ID is always Zero.
In IO parameter settings, You can configure any parameter as High Priority.The records generated by this parameter contains AVL ID of that parameter as Event IO ID.
If you configure ignition as high priority event, and a new record generated by triggering the ignition, contains IO ID 239 as Event IO ID.
Please find the below link for AVL IDs
