Section 8. Operation • Initializes system variables. • Clears communications memory. 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. 77). Beginning with CR1000 operating system v.16, 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 CR1000s in remote and difficult-to-access locations. 8.3.3.2 Program Send Reset Final Storage (p. 454) 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. 454) command and CRBasic Editor Compile, Save and Send (p. 451). See Preserving Data at Program Send (p. 110) for a more-detailed discussion of preserve / erase data at program send. 8.3.3.3 Manual Data-Table Reset Data-table memory is selectively reset from • Support software Station Status (p. 466) command • external keyboard / display: Data | Reset Data Tables 8.3.3.4 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 associated with the program are erased. Drive formatting is performed through datalogger support software (p. 569) Format (p. 454) command. 8.3.4 File Management As summarized in table File Control Functions (p. 341), files in CR1000 memory (program, data, CAL, image) can be managed or controlled with datalogger support software (p. 77), CR1000 web API, or CoraScript. Use of CoraScript is described in the LoggerNet software manual, which is available at www.campbellsci.com.

Section 8.
Operation
340
Initializes system variables.
Clears communications memory.
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. 77).
Beginning with CR1000 operating system v.16, 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 CR1000s in remote and difficult-to-access locations.
8.3.3.2 Program Send Reset
Final Storage
(p. 454)
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. 454)
command and
CRBasic
Editor
Compile, Save and Send
(p. 451).
See
Preserving Data at Program Send
(p.
110)
for a more-detailed discussion of preserve / erase data at program send.
8.3.3.3 Manual Data-Table Reset
Data-table memory is selectively reset from

8.3.3.4 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
associated with the program are erased. Drive formatting is performed through

8.3.4 File Management
As summarized in table
File Control Functions
(p. 341),
files in CR1000 memory
(program, data, CAL, image) can be managed or controlled with
datalogger
support software
(p. 77),
CR1000 web API
,
or
CoraScript
.
Use of
CoraScript
is
described in the
LoggerNet
software manual, which is available at
www.campbellsci.com
.

datalogger security, see the
Security
(p. 70)
