Question:
How are tags counted in E3, for licensing purposes?
Solution:
Only communication tags and blocks are counted for this purpose (according to their size — Size property), whether communication happens via driver or via OPC. Internal, demo, timer, and other types of tags, are not taken into consideration for licensing, and therefore can be used freely.
Question:
How are tags counted when N/B parameters are altered at runtime?
Solution:
Each time the N/B parameters combo sets up a new tag, the counter will be incremented. When the maximum amount in the license is reached, the new tags will not be able to communicate, but this will not affect communication with previous tags, nor will domain execution stop.
You can check the tags counter while the domain is running. To do so, just open the Licenses window in E3 Server and click Update button to check the number of tags in use at that moment.
