This is how I generally handle this issue when using a single tag database for multiple systems. Export the tags to a .csv (comma separated variable) format. Open it with Excel. Create a new sheet that formats the pertinent tag columns in a manner suitable to each of the other programs. You can find out the format required by each program by exporting tags from them in csv format and looking at the arrangement of the information. Save the reformatted sheet as a .csv and then import it into the HMI software. I don't use RSViewME, but Panelbuilder will let you copy and paste from excel directly into its tag editor. RSView32 will let you export/import a .csv tag file. One of these methods should be possible with RSViewME. You then may have to go back and fill in the blanks.
When dealing with a large system, I create the tag database early on, save it as an .xls and make it the master copy for all the programs. When I need to make changes, I make them on the master copy, and save the individual sheets as .csv files for importing into the other programs that use those tags. This helps keep all devices "on the same page" with regard to tag names and addresses.
