Enter the serial number of the F60 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 F60 device specified by the serialnumber.4.1.7 SETTINGS FILE TRACEABILITYA traceability feature for settings files allows the user to quickly determine if the settings in a F60 device have beenchanged since the time of installation from a settings file. When a settings file is transfered 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 F60device or obtained from the F60 device. Any partial settings transfers by way of drag and drop do not add the traceabilityinformation to the settings file.Figure 4–11: SETTINGS FILE TRACEABILITY MECHANISMWith respect to the above diagram, the traceability feature is used as follows.2The serial number and last setting change dateare stored in the UR-series device.The serial number of the UR-series device and the file transferdate are added to the settings file when settings filesare transferred to the device.842864A1.CDRCompare transfer dates in the settings file and theUR-series device to determine if securityhas been compromised.1 SETTINGS FILE TRANSFERREDTO UR-SERIES DEVICESERIAL NUMBER AND TRANSFER DATESENT BACK TO ENERVISTA ANDADDED TO SETTINGS FILE.
