Configuration Notes:
When considering questions with licensing law implications, a general distinction can be made between internal, external and archive tags. Only external tags and archive tags count as far as licensing is concerned.

The table below contains an overview of the different types of tags and explains their significance in terms of licensing.
Tag type Meaning
External WinCC tags The number of external WinCC tags is of significance for RC and  RT license types.

RC means that a certain number of external WinCC tags can be used both in configuration and in runtime mode depending on the license. RT means a certain number of external WinCC tags can be used in runtime mode depending on the license. Configuration can be limited with an RT license to max. one hour in "demo mode".

Internal WinCC tags Internal WinCC tags are of no significance to licensing.
Archive tags The number of archive tags is only of significance in connection with the licenses for WinCC archive power packs.


  • Licenses for WinCC archive power packs have been introduced since WinCC version V6. Archive tags were of no significance to licensing in earlier versions of WinCC.
  • From WinCC version V6.0.0.3 licenses for WinCC archive power packs are only necessary for the runtime mode of an archive configuration with more than 512 archive tags. You can also configure more than 512 archive tags without this license in CS without "demo mode".
  • Since WinCC version V6.0 SP3, archive tags in compressed archives have no longer been of significance to licensing.

If, for example, you have installed an RC128 PowerTags license on your computer, you can configure 128 external tags and use them in runtime. If you create an instance tag for a type of structure with five external structural elements, five external tags are created which count according to the license. 

A raw data tag counts as one external tag. It uses a counter irrespective of its size.
