Presentation
Unity DIF is a companion software for Unity Pro. It compares two Unity Pro
applications and displays an exhaustive list of the differences. The differences are
displayed graphically and textually based on the type of program/section chosen.
Unity DIF improves productivity during the main life stages of a control system,
mainly during development and debugging of applications and commissioning,
operation and maintenance of the installation.
Software setup
Unity DIF compares two Unity Pro application les (XEF, ZEF, STU and STA) and
detects anything ADDED, DELETED and MODIFIED. The user interface and
graphical representation of differences are similar to Unity Pro for consistency and
ease of understanding the differences.
Unity DIF can be launched in several ways:
b From Unity Pro
b From the Windows Start menu
b From a command line interface
The user interface and graphical representation of differences are similar to
Unity Pro graphics for consistency and ease of detecting the differences.
