For the Schneider Electric Unity Pro, they do have versions labeled differently. Their software includes Unity Pro for programming, which might have different product lines. Their versioning might use numbers like V12.0, but I need to check if XL is part of their naming. Searching their site, Unity Pro includes different types, like Unity Pro (standard), Unity Pro XL (extended license or extended features?), which might be a version for more complex projects. The download would be from their official site, requiring login and appropriate license.
