7.1.3.2 Applications
•
Commands 1, 2, 6, 13, and 14 (Run Now and/or Run On Power-up). If a
device other than CRD: drive is specified, the file will be copied to that
device.
•
Command 1, 2, and 13 (Run On Power-up). If the copy (first application,
above) succeeds, the new Run On Power-up program is accepted. If the
copy fails, no change will be made to the Run On Power-up program.
•
Commands 1, 6, 13, and 14 (Run Now). The Run Now program is changed
whether or not the copy (first application, above) occurs. If the copy does
succeed, the Run Now program will be opened from the device specified.
•
Commands 13 and 14 (Delete Associated Data). Since CRD:powerup.ini is
only processed at power-up, there is not a compiled program to delete
associated data for. The information from the last-running program is still
available for the datalogger to delete the files used by that program.
7.1.3.3 Program Execution
After File is processed, the following rules determine what datalogger program
to run:
1) If the Run Now program is changed, it will be the program that runs.
2) If no change is made to Run Now program, but Run on Power-up program
is changed, the new Run on Power-up program runs.
