10.4 Compare settings

Settings can be compared against default values and between two UR devices.
Some of the IEC 61850 settings use floating point data, which guarantees accurate representation of real numbers up to
seven digits. Numbers with more than seven digits are approximated within a certain precision. This can result in
differences between what is entered and what is saved, and for example results in differences shown on a settings
comparison report.

10.4.1 Compare against defaults

To compare settings against default values:
1. Right-click the device in the Offline Window area and select Compare Settings With Defaults. The file generates and
the number of differences displays.
2. To save the report, click File > Save As, select the TXT, PDF, or CSV format from the drop-down list, and enter a name
for the file.
In the figure, the first entry (red) is from the device, while the second (green) is the default value.

10.4.2 Compare two devices

Preferences can be set under File > Preferences as follows:
• Comparison Report: Sequential File 1, File 2 Layout — When disabled (default), the report shows only what differs, as
shown in the previous figure. When enabled, the report indicates differences by device.
