You are asked whether to delete the tags associated with the collector. Selecting Yes removes all tags using that collector's interface name (name matching that of the collector being deleted), but not the data for those tags. It is recommended that you select No. This allows you to resume collection of the tags later.
Note: Prior to deleting tags, it is recommended to export the tags associated with the collector name to a spreadsheet using the Excel Add-In and then save the spreadsheet for future reference. For more information on exporting tags with the Excel Add-In, refer to Using the Historian Excel Add-In >
