Data Archiving
Pressing the Data Archiving button opens the External Data Archiving
dialog box.
This panel supports various features in external mode, including:
• Directory notes — directory level annotation
• File notes — file level annotation
• Data archiving — Automated data logging and storage
Directory Notes. Pressing the Edit directory note button opens the MATLAB
editor. Place comments in this window that you want saved in the specified
directory.
File Notes. Pressing Edit file note opens a file finder window that is, by default,
set to the last file to which you have written. Selecting any MAT-file opens an
edit window. Add or edit comments in this window that you want saved with
your individual MAT-file.
Data Archiving. Clicking the Enable Archiving check box activates the
automated data archiving features of external mode. To understand how the
archiving features work, it is necessary to consider the handling of data when
archiving is not enabled. There are two cases, one-shot and normal mode.
In one-shot mode, after a trigger event occurs, each Scope block writes its data
to the workspace just as it would at the end of a simulation. If another one-shot
is triggered, the existing workspace data will be overwritten.
In normal mode, external mode automatically rearms the trigger after each
trigger event. Consequently, you can think of normal mode as a series of
one-shots. Each one-shot in this series, except for the last, is referred to as an
