The Delimited File Import Manager view is the default view on the Histories extension (FileHistoryDeviceExt) of a FileDevice (in a FileNetwork). See Figure 155.
This manager view is similar to other driver’s history import managers—see History Import Manager. However, there is no “Discover” feature to add history file import descriptors (types ExcelCsvFileImport and DelimitedFileImport). Instead, you use the History Import New function to add history file import descriptors, as each is simply to reference a local delimited-type text file (such as a CSV type).
Like other manager views, the Delimited File Import Manager view is a table-based view, where you create () history file import descriptors, or double-click existing import descriptors to make Edits. For details, see the next section Delimited File Import Manager usage notes.
The following notes apply specifically to using the DelimitedFileImportManager view, the view most used within a FileNetwork (outside of property sheets for created history file import descriptors).
-
When adding a new descriptor, select the ExcelCsvFileImport type over the DelimitedFileImport type whenever the source file is a CSV type that was created using Microsoft Excel. This provides more support for importing “complex” CSV-formatted data—for example, including data that incorporates comma usage(s) within data fields.
-
Add a single descriptor referencing a File that is patterned like other delimited files you wish to import, then adjust configuration properties of that descriptor until it executes (imports a history) properly—without a fault status. Note the Timestamp Format property may take some tweaking.
Then, duplicate that working import descriptor, (and before executing) change its File reference, History Id, and whatever other properties you wish to keep unique. This saves engineering time.
