Section 2. Data Storage and Retrieval

2.3.1.2 Collection Method
All Records, Create New File – Collects the entire table stored in the
CR9000. PC9000 gets the current record number from the table in the
CR9000 and then retrieves the oldest record in the table up to the current
record number. The number in the file name is incremented to create the
file name in which the data are stored.
Since Last, Create New File – Click here to save new data in a new file.
PC9000 searches for the last file with the Root name, gets the last record
number from that file, then the current record from the table in the CR9000,
and requests all records in between those numbers from the CR9000. The
number in the file name is incremented to create the file name in which the
data are stored.
Since Last, Append To File – Click here to append retrieved data to the
end of the named file. PC9000 searches for the last file with the Root
name, gets the last record number from that file, then the current record
from the table in the CR9000, and requests all records in between those
numbers from the CR9000. The data are appended to the existing file.
Number of Records, Create New File – Collects the number of records
entered in Num of Recs box. Retrieves that many records back from the
current record number. The number in the file name is incremented to
create the file name in which the data are stored.
Num of Recs – Enabled when Number of Records, Create New File is
checked. Enter the number of records back from the current record number
to retrieve.
2.3.1.3 Table Selection
All Tables – When the All Tables box is checked, all data tables except the
Public and Status tables are collected when collection is executed. The
data from each table are stored in a file with the table name and increment
number (see Table naming). This is a convenient method of collecting all
data from the CR9000. The first time data are collected, “all data” is
checked and the file type and collection method are selected. PC9000
remembers the settings, and on subsequent collections the operator only
needs to click on execute.
Stream – acts the same as Write file for the selected Table Name (Section
2.3.2).
Table Name – When "All tables" is not checked, a single data table can be
selected for collection. The Table Name box is used to select the table to
be retrieved.
Reset Table – Resetting a data table erases all data in the table and sets the
record number back to 0. Unless the table is configured as fill and stop by
the CR9000 program, it is not necessary to reset the table because the
"Since Last" collection option can be used to get only the new data. If the
table is configured as fill and stop, it stops collecting data once full and
must be reset before more data can be collected. Use with caution.
