4.1.7 SETTINGS FILE TRACEABILITY
A traceability feature for settings files allows the user to quickly determine if the settings in a F60 device have been
changed since the time of installation from a settings file. When a settings file is transferred to a F60 device, the date, time,
and serial number of the F60 are sent back to EnerVista UR Setup and added to the settings file on the local PC. This infor-
mation can be compared with the F60 actual values at any later date to determine if security has been compromised.
The traceability information is only included in the settings file if a complete settings file is either transferred to the F60
device or obtained from the F60 device. Any partial settings transfers by way of drag and drop do not add the traceability
information to the settings file.
Figure 4–11: SETTINGS FILE TRACEABILITY MECHANISM
With respect to the above diagram, the traceability feature is used as follows.
1. The transfer date of a setting file written to a F60 is logged in the relay and can be viewed via EnerVista UR Setup or
the front panel display. Likewise, the transfer date of a setting file saved to a local PC is logged in EnerVista UR Setup.
2. 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.
a) SETTINGS FILE TRACEABILITY INFORMATION
The serial number and file transfer date are saved in the settings files when they are sent to a F60 device.
The F60 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 below.

The serial number and last setting change date
are stored in the UR-series device.
The serial number of the UR-series device and the file transfer
date are added to the setting file when setting files
are transferred to the device.
