If you select Logged, SPC retrieves data from an ODBC database table that has already been updated by CIMPLICITY. Define logged collection in the Variable Quality Characteristics Properties dialog box.
Note: SPC logs all of its data. Therefore, the Logged option is not necessary for saving data. It refers to using an additional data source for input. The Point collection method is more efficient.
To specify logged for data collection:
Select the Collection tab.
Click the Logged radio button.
Use the ODBC data source drop-down list to select the name of the database from which SPC will retrieve data.
In the Database user field, enter a name for the user when logging into the ODBC data source.
In the Password field, enter a password for the user when logging into the ODBC data source.
Click to browse for the Table ID where data is located.
Click to browse for the Column ID where data is located.
Check the Manual entry allowed box to enable manual data entry for SPC chart sets at runtime; clear to disable option.
Step 3.3. Define a variable's collection characteristics.
