Section 5. Real-Time Tools
To summarize, any change in data table structure will delete all tables
on the dataloggers CPU, regardless of whether or not the Preserve
Data option was chosen. If the Preserve Data option was chosen but
the datalogger was unable to retain the existing data, the following
message will appear in the Compile Results: Warning: Internal Data
Storage Memory was re-initialized.
CR9000(X)/CR5000 Datalogger Run Now Options
The Run Now options and behavior for the CR9000(X) and CR5000
dataloggers are different from the CR1000, CR3000, and CR800
Series dataloggers. Below is a dialog box for a CR5000 datalogger.
When Run Now is checked, the program is compiled and run in the
datalogger. All data tables on the CPU are erased. You have the
option of whether or not to erase data files stored on a card.
Run On Power-up
The file will be sent with the Run On Power-up attribute set. The
program will be run if the datalogger loses power and then powers
back up.
Run Always
Run Now and Run On Power-up can both be selected. This sets the
programs file attribute in the datalogger as Run Always. The
program will be compiled and run immediately and it will also be the
program that runs if the datalogger is powered down and powered
back up.
Pressing Run Options to restart a stopped program in the CR1000, CR3000, or
CR800 displays a different dialog box. From the dialog box you choose
Restart Program to begin running the selected program immediately. You can
also select an option button to determine whether or not the data tables
previously created by the program are erased or retained. Note that you cannot
change the Run on Power-up option when restarting a program.
