Enter the serial number of the D30 device to lock to the settings file in the
Serial # Lock
field.
The settings file and corresponding secure FlexLogic equations are now locked to the D30 device specified by the serial
number.
4.2.3 SETTINGS FILE TRACEABILITY
A traceability feature for settings files allows the user to quickly determine if the settings in a D30 device have been
changed since the time of installation from a settings file. When a settings file is transferred to a D30 device, the date, time,
and serial number of the D30 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 D30 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 D30
device or obtained from the D30 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.

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.
