How to Import Tags
Export Tag (*.XSY) from Unity Pro XL
In Unity Pro XL, navigate to Variables & FB instances, then select Export to save the tag file as *.XSY.

Export Tag (*.SCY) from PL7 PRO
In PL7 PRO, open the Variables section and create your data. Then go to File > Export to save the tag file as *.SCY.
NOTE: Symbol must have data to be exported.


Import Tags into EBPro (EasyBuilder Pro)
Open System Parameter Settings
In EBPro (EasyBuilder Pro), go to System Parameter Settings and click Import Tags.
Select the file type
Choose the file type to import:XSY Files (*.xsy)for Unity Pro XL exports, orSCY Files (.SCY)for PL7 PRO exports.
Select tags to import
In the Add Tags dialog, select the tags to import into the project and click OK.
