Enter the serial number of the F35 device to lock to the settings file in the Serial Lock field.3. Click the OK button to apply the change.The settings file and corresponding secure FlexLogic equations are now locked to the F35 device specified by the serialnumber.4.1.9 Settings file traceabilityA traceability feature for settings files allows the user to quickly determine if the settings in a F35 device have beenchanged since the time of installation from a settings file. When a settings file is transferred to a F35 device, the date, time,and serial number of the F35 are sent back to EnerVista UR Setup and added to the settings file on the local computer. Thisinformation can be compared with the F35 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 F35device or obtained from the F35 device. Any partial settings transfers by way of drag and drop do not add the traceabilityinformation to the settings file.Figure 4-13: Settings file traceabilityWith respect to the figure, the traceability feature is used as follows.1. The transfer date of a settings file written to a F35 is logged in the relay and can be viewed in the EnerVista softwareor the front panel display. Likewise, the transfer date of a settings file saved to a local computer is logged in theEnerVista software.2. Comparing the dates stored in the relay and on the settings file at any time in the future indicates if any changes havebeen made to the relay configuration since the settings file was saved.4.1.9.1 Settings file traceability informationThe serial number and file transfer date are saved in the settings files when they are sent to a F35 device.The F35 serial number and file transfer date are included in the settings file device definition within the EnerVista UR Setupoffline window as shown in the example.
