External tags have address in PLC space. These are the tags, which are counted by WinCC license (the one you specify when you buy WinCC). Power tag are tag whch you use to increase (upgrade) your existing WinCC license. For example you bought WinCC with 128 (external) tags. You need more tags because the client change his mind and wants to incorporate more devices. You need to buy Power tag to increase your license to 2048 tags for example. Archive tags are the variables which you archive in WinCC database. They could get their information from internal or external tags. When you buy WinCC (the type of license is irrelevant), it comes with 512 archive tags. I you want to archive more than 512 tags, you need to by upgrade license for archive tags. regatds, yolov

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. Note: 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 ofnosignificance to licensing.
Archive tags	The number of archive tags is only of significance in connection with the licenses forWinCC archive power packs. Notes: Licenses for WinCC archive power packs have been introduced sinceWinCC version V6. Archive tags were of no significance to licensing in earlier versions of WinCC. FromWinCC version V6.0.0.3licenses 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". SinceWinCC version V6.0 SP3, archive tags incompressed archiveshavenolonger been of significance to licensing.

Example:
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 asoneexternal tag. It uses a counter irrespective of its size.
