Section 6. Storing and Retrieving
Datalogger Programs
CR500/510, CR10/10X, CR23X, 21X and CR7 programs can be uploaded and downloaded
between the datalogger and the Storage Module in the *D Mode. (OSX and OS7 series
PROMs are required for the 21X and CR7.) Campbell Scientific’s SMS software allows
programs to be transferred between the computer and the SM. Using these capabilities, a
program can be developed in the computer, stored in the SM and then carried to the field and
downloaded to the datalogger.
The SM can store up to eight programs, numbered 1 to 8. These are stored in an area of
memory separate from that used for data storage.
With the release of the OS series PROMs (OS10, OSX, OS7), the dataloggers were given the
capability of automatically loading program 8 if a Storage Module is connected to the
datalogger when the datalogger is powered up. This feature is standard in the CR500/510,
CR10/10X and CR23X dataloggers.
21X and CR7 PROMs before the current OSX and OS7 versions do not have the capability to
store and directly load programs from the SM. For these dataloggers, programs may be
transferred via the DSP4 Heads Up Display (see Section 6.3).
6.1 SMS Storage Module Support Software
Select the Program tab in SMS. Refer to the PC208W manual for more
information.
6.2 *D Mode — With Datalogger
The *D Mode is used to transfer programs between the datalogger and Storage
Module. The general commands in Table 6-1 are used to save, retrieve or clear
programs from the Storage Module. Refer to the appropriate datalogger manual
for instructions on using the *D Mode.
Table 6-1 *D Mode Keyboard Commands
Key Display Description
*D 13:00 Enter *D Mode
7XA 7X:00 Address Storage Module X
1YA Store Program in SM as Y (Y=1..8)
2YA Load Program Y from SM
3YA Erase Program Y from SM
13:0000 command completed
The program is stored, retrieved, or erased by referring to a program number
(1...8) in the Storage Module. If the program to be retrieved does not exist in the
Storage Module, the error message ‘E99’ will be displayed.
There are 128 kbytes of memory available for program storage. For example, you
can store one 128 kbyte DLD file or 8 x 16kbyte files. Flash memory technology
affects the use of memory when storing and erasing programs.
