Enter the serial number of the C30 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 C30 device specified by the serial
number.
A traceability feature for settings files allows the user to quickly determine if the settings in a C30 device have been
changed since the time of installation from a settings file. When a settings file is transfered to a C30 device, the date, time,
and serial number of the C30 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 C30 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 C30
device or obtained from the C30 device. Any partial settings transfers by way of drag and drop do not add the traceability
information to the settings file.
The serial number of the UR-series device and the file transfer
date are added to the settings file when settings files
are transferred to the device.
Compare transfer dates in the settings file and the
UR-series device to determine if security
has been compromised.
With respect to the above diagram, the traceability feature is used as follows.
