3. Enter the serial number of the D60 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 D60 device specified by the serial
number.
A traceability feature for settings files allows the user to quickly determine if the settings in a D60 device have been
changed since the time of installation from a settings file. When a settings file is transferred to a D60 device, the date, time,
and serial number of the D60 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 D60 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 D60
device or obtained from the D60 device. Any partial settings transfers by way of drag and drop do not add the traceability
information to the settings file.
With respect to the above diagram, the traceability feature is used as follows.
