History tag ABC123 references ABC123.<tagatom> (not found in any database)
Only Conductor NT systems can produce this message.
The history database refers to a tag that does not exist in the tag database associated with this console. The history tag has not been defined, although it is shown. Note that trend definitions are also affected. Since this history tag has no meaning, there is clearly a problem with any trend group that references it.
Example:
History tag CBTE01 references CBTE01.C_APV (not found in any database).
The Historical Tag can have any legitimate name, including CBTE01. However, the "Tag Atom" entry must refer to a legitimate database value. In this case, the problem is that there is no database tag "CBTE01", which means that Tag Atom "CBTE01.C_APV" is erroneous. If the entry in Tag Atom were changed to have the "CBTE-01" in the name, there would be no error.
Usually, this message comes because no such tag is in the database at all, often because it did exist but was deleted. DBDOC checks that the tag name and tag atom make sense.
In the example, the error refers to an invalid Historical Tag, not a missing one. The other form of the error is, of course, to name a trend tag that does not exist at all. To resolve that error, you either eliminate the trend tag entry in the Trend Configuration section, or you correct the spelling of the Trend Tag entry in the Trend group.
This message is likely to show an error in the system configuration. It should be reviewed. The issue raised may be in unused logic or graphics, or have other realities that make it a non-issue.
