Figure 4-13: Settings file traceability
With respect to the figure, the traceability feature is used as follows.
• The transfer date of a settings file written to a D30 is logged in the relay and can be viewed in the EnerVista software
or the front panel display. Likewise, the transfer date of a settings file saved to a local computer is logged in the
EnerVista software.
• Comparing the dates stored in the relay and on the settings file at any time in the future indicates if any changes have
been made to the relay configuration since the settings file was saved.

The serial number and file transfer date are saved in the settings files when they are sent to a D30 device.
The D30 serial number and file transfer date are included in the settings file device definition within the EnerVista UR Setup
offline window as shown in the example.
