Tags need Renaming in existing Historian Data Blocks without losing the History for those Tags
Before you use this utility you are recommended to do the following
1 Move the history blocks where you want to rename a tag outside of the current Circular and Alternate directories, rename the tags and then, optionally, move the history blocks back
2 Stop InSQL, rename the tags, and then restart InSQL.
Open the Tag Rename Utility
You will then need to browse to your History Block(s) then click OK
This will then be updated into the Utility and then click Next
You then will need to type in the current Tag you wish to change and then enter it’s new format. If there is more than one Tag repeat these steps or you can use a CSV file by clicking the relevant button.
All the History Blocks that are available in the Folder you selected will appear. Click on the Check All Button then Click Next
