I use the tag engine to connect with the KEPWARE OPC server program and at times I want to change how the tags are located inside KEPWARE but keep the same tagnames inside LABVIEW. I export the .scf file and modify it inside EXCEL. When I import it again it will create duplicate tagnames. When you have 4000-8000 tags, it can take awhile to delete the duplicates. It would be great if we could replace the existing tag name data. Maybe I should be creating a vi to modify the properties of individual tags instead. How does anyone else work around this issue??
