As I understand, calculation tags do not count towards license..But what if we put manual data in it? Will it count towards license?

And if we use it in script, will it count towards license?

Even with manual data, calculation tags don't count against your tag license. As a general rule, only tags with I/O addresses count.

Hi Dave, Thanks for reply. How about we use it in script?

I found vtscasda help guide as below. Please clarify what it means code level?

The tag limit applies only to legacy and I/O and Calculations tags that have a read or write address or any tag that has been modified at the code level.
