Simple Sample and TIPs - WinCC Unified - Tag counting and usage

As from TIA V18 the tag count for licensing and use become some changes:

• Only tags effectively in use are counted. The number of the configured tags are also shown in the compilation logs as “Number of tags”, but their quantity does not imply limitations.
• The variables actually used (screens, trends, alarms) are also counted (as “Number of used tags”) and these, yes, are taken into account for the purpose of operating limits and licensing.
• Internal Tags are taken into account for the purpose of operating limits and licensing.
• A tag being used explicitly within a script is counted the same as a tag used directly on the object.
• A tag being used explicitly within a script is counted the same as a tag used directly on the object.
• A tag being used implicitly within a script (that is, its name cannot be determined outside of runtime) is not counted as a tag used directly on the object.
• Energy Suit Tags  are not taken into account for the purpose of operating limits and licensing.
