All of the field values for cards are similar. Only a few cards have card-level parameters and these cards have only a few parameters. Unless you want to bulk edit card-level parameters you can use the Card.fmt format specification file included with the DeltaV software to export and import local I/O card data.
If you need to bulk edit a large number of cards that have card-level parameters, you can create the format specification files for each of the card types you want to bulk edit. To include card-level parameters in format specification files you must correctly specify the Subtype (browse to the location of the card you want to bulk edit).
