When a settings file is transfered to a M60 device, the date, time,and serial number of the M60 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 M60 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 M60device or obtained from the M60 device.
