Section 8. Operation operations. The maximum record number is &hffffffff (a 32-bit number), then the record number sequence restarts at zero. The CR6 reports back to the datalogger support software 31 bits, or a maximum of &h7fffffff, then it restarts at 0. If the record number increments once a second, restart at zero will occur about once every 68 years. 8.3.2 Memory Reset Four features are available for complete or selective reset of CR6 memory. 8.3.2.1 Full Memory Reset Full memory reset occurs when an operating system is sent to the CR6 using DevConfig or when entering 98765 in the Status table field FullMemReset. A full memory reset does the following: • Clears and formats CPU: drive (all program files erased) • Clears SRAM data tables • Clears Status-table elements • Restores settings to default • Initializes system variables • Clears communication memory • Recompiles current program Full memory reset does not affect the CRD: drive directly. Subsequent user program uploads, however, can erase CRD:. Operating systems can also be sent using the program Send feature in datalogger support software (p. 89). Settings and status are preserved when sending a subsequent operating system by this method; data tables are erased. Rely on this feature with caution, however, when sending an OS to CR6s in remote and difficult-to-access locations. 8.3.2.2 Program Send Reset Final-memory (p. 496) data are erased when user programs are uploaded, unless preserve / erase data options are used. Preserve / erase data options are presented when sending programs using File Control Send (p. 496) command and CRBasic Editor Compile, Save and Send (p. 492). See Preserving Data at Program Send (p. 129) for a more-detailed discussion of preserve / erase data at program send. 8.3.2.3 Manual Data-Table Reset Data-table memory is selectively reset from • Support software Station Status (p. 509) command • external keyboard display: Data | Reset Data Tables 8.3.2.4 Formatting Drives CPU:, USR:, USB:, and CRD: drives can be formatted individually. Formatting a drive erases all files on that drive. If the currently running user program is found on the drive to be formatted, the program will cease running and any SRAM data 383
