Unity Pro - Xl V13

Unity Pro XL v13 supports five distinct PLC families from a single project:

Version 13 is a significant release because it sits comfortably between the older "Classic" architecture and the newer EcoStruxure era. It is often the "sweet spot" for legacy migrations because it supports both older hardware migrations and newer remote I/O configurations.

Unity Pro is sensitive to versions. If a contractor saves a project in v13 with Service Pack 2, and you try to open it with v13 "Base" (no service pack), you will likely get an error. Always check the .stu (Station) file version.
