Event for parameter change or tag deleted

Hello,

i have a memory Tag which holds a specific Parameter for every Tag. Whenever i create a tag i add a row with the path and the parameter to the dataset of the memory tag. This works.
Now i want to track changes if the parameter is changed (at this moment i do this through a tag restart but i hope there is a better option) or if the tag is deleted. So is there any event or something like that which i can catch to implement a script for this case?

Thank you

No, tag properties (and UDT parameters) do not generate any change events. There are some interfaces in the SDK that might work, but expect fragility and likely memory leaks if you attach jython listeners to the tag manager.
