Searching a Tag Using Advance Search Criteria

About this task

The Advanced Tag Search dialog allows you to search the set of tags that match the search criteria and then to perform actions based on one or more tags that you select from the list. It saves the most recently used search criteria to a file named DefaultSearchCriteria.xml in the Excel AppData path (c:\user- s\<username>\AppData) and this criteria is automatically loaded into the dialog the next time it is opened. This feature allows you to re-use or modify the criteria rather than entering them each time. If you want to reset your criteria, delete the XML file.

Using this search dialog, you can:
  • Add multiple search criteria based on the tag criteria and the criteria value.
  • Modify the existing criteria value.
  • Delete the unwanted search criteria from the list.
  • Save any list of criteria to a file.
  • Load a saved criteria list for searches.
  • Automatically load the most recently used criteria for re-use.
  • Search the Historian database based on the search criteria.
  • View the details of a tag.
