A traceability feature for settings files allows the user to quickly determine if the settings in a L60 device have been
changed since the time of installation from a settings file. When a settings file is transferred to a L60 device, the date, time,
and serial number of the L60 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 L60 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 L60
device or obtained from the L60 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.
