Database Error: Data type for Ref. Tag '<tag name>' unknown. Setting Alias Tag '<tag name>' data type to Default ('<type>')

Error Type: Warning

Possible Cause:

The data type of the "Alias For" *tag referenced in the Alias Tag's declaration could not found in the Tag Import file. This data type is necessary to generate the alias tag correctly.

Solution: The Alias Tag will take on the default type specified in the Default Type tab in Device Properties.

Note:

In RSLogix5000, "Alias For" is a column in the tag view under the Edit Tags tab. This is where the reference to the tag, structure tag member, or bit that the alias tag will represent is entered.
