Check, if the data in the non-volatile memory, referred to as NVRam, (message logger, retain variable) was valid when booting the PacDrive Controller.
This function reads the status of NVRam while booting. This may be required if the PacDrive Controller was de-energized for an extended period.
If the NVRam is not OK, then the system writes automatically an entry into the message logger during the restart process (316 "NvRam CRC error").
