Section 2. Data Storage and Retrieval
2-6
2.3.1.4 File Control
The default naming for a file stored to disk is to use the data table name
appended with a 2 digit number and the extension
.DAT . If the table name
is longer than 6 characters, it is truncated. For example, the table name
EVENTS is stored as EVENTS00.DAT. A table named CYLTEMP is
stored as CYLTEM00.DAT.
When the file collection options that create a new file are used, each time a
table is collected, the 2 digit number is incremented (e.g.,
EVENTS00.DAT, EVENTS01.DAT, EVENTS03.DAT ...). PC9000
searches the selected directory and adds 1 to the number of the highest
numbered file of the matching name to create the new name.
When the new data are to be appended to the existing file, PC9000 searches
the selected directory for the highest numbered file of the matching name,
and appends the data to that file.
Change File – Press the Change File button to change the name of the file
to be stored on disk. This is not possible when "All Tables" is selected.
Set Path – Press here to select a different disk or directory to write the files
to.
EXECUTE – Press here to begin collecting data.
2.3.1.5 Status Messages
TABLE SIZE – Shows the size (in records) of the table highlighted in the
Table Name box above.
COLLECTION RANGE – Displays the range of records to be collected.
More records than the last number in this range may actually be retrieved.
LOGGER MESSAGE – Displays messages from the CR9000.
2.3.2 RealTime Write File
This feature is provided to allow the user to start and stop collecting data
for some event without leaving the real-time window. Check this box to
write the current table to a file in the computer. Writing begins with the
current record and continues until the Write File box is unchecked or until
the window is closed.
This collection method requires that the PC is connected to the CR9000
while the data are collected. Because the beginning and end points of the
data file are roughly determined by when the box is checked, this is best
suited to collecting data when the user rather than the measurements
determine when data should be collected.
The bottom line of the screen will periodically display the current record
being written. The name of the file written will be the first six characters
of the table name plus 2 digits and an extension of .DAT. If the table name
is MAIN then the first file created will be named MAIN00.DAT. The next
