Is there a way to create multiple instances of user defined data types by importing a .csv or other file that contains the tag instances and the values for the data type parameters? I want to create many tag instances without having to type in the values for the data type parameters individually.

Yes, first create a single instance of the UDT. Once created select it and press the button in the SQLTags browser to export it to a CSV file. Once there copy and paste the two lines to make multiple tags changing the param name and tag name. Save the file and import it back in.

**NOTE** Just export a single tag not the entire tags folder.

OK thanks, that worked. Not sure but I think there may be a minor bug… I tried this solution originally, on a tag instance that was created from a UDT, and then added the data type parameter to the UDT (sequence: created UDT (no paramters), created tag instance, modified UDT (added data type paramter). When I exported the tag instance, the parameter was not included in the export and so I assumed this process does not work for UDT’s. Creating a UDT with all parameters upfront and exporting from tag instances seems to work properly.
