  • From Unity Pro
  • From the Windows Start menu
  • From a command line interface
  • Unity DIF can provide differences for the following sections:
  • PAC Configuration (Hardware and Network)
  • Derived Data Types
  • Derived FB Types
  • Variables and FB Instance
  • Motion
  • Communication
  • Programs
  • Animation Table
  • Operator Screen
  • DTM Catalog
  • Project Settings
  • The result of the comparison can be printed or saved in .pdf and .txt file formats.
