Tag index not found [ERROR 272]

Tag index not found [ERROR 272]

Tag index 423 not found in 3ls1045-.dt at 1942,3444

This message means that a symbol has a tag index that is not found in the tag (or trend) database. The name of the tag might be blank or not found in the database either.

The value of this message for pop-ups is significant, as it is the easiest way to find out that pop-ups that have been keyed by index refer to tags that no longer exist.

This message can be important in conversion of SODG systems to Symphony Plus.

Note that tag index values 1, 6 and 100 are built into ABB standard symbols, so must be ignored if they show up.

The conversion of SODG graphics, even ones using names as keys, is done using tag index values in .DT text files. Any errors in tag name to index mapping will cause problems.

This message can be found in unused symbols. The recommended technique is to use DBDOC builds to remove unused symbols iteratively, so that it is clear that errors apply to symbols that are used.

DBDOC has techniques for finding and eliminating blank tagnames.

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.
