Import/Paste Configuration Dialog - Configure Rung Properties Overview
Use this dialog box to configure rung properties when the import component is a selection of Ladder Diagram rungs.
The Import Content shows the routine name (that the rungs are being imported into) and any references in the References folder (if there are any referenced tags, data types, Add-On Instructions, or other components).
Tag references are represented in the Import Content by the tags item found under the References folder. When this item is selected, the tag references grid displays. The grid includes any tag directly referenced by the imported rungs.
When the routine is selected in the import content, the properties of the routine are displayed, along with information about how many rungs are being imported, and where they will be inserted.
Parameters
Import Rungs
Displays the number of rungs as read from the import file (read-only).
Operation
Identifies what is done with the rung upon import.
If you checked Overwrite Selected Rungs on the Import Rungs dialog box, then the rungs collide with the existing rungs and Overwrite or Use Existing are the only valid options for the Operation field.
If you did not select Overwrite Selected Rungs on the Import dialog box, then the rungs do not collide with existing rungs, and Create or Discard are valid operations.
Note that the Use Existing and Discard options do not import the rungs, but import the references as they are configured in the references folders.
Text appears to the right of the Operation field that identifies where the imported rungs affect the routine.
For more information, see
Import Configuration Operations
.Name
The name of the routine into which the rungs are being imported.

Displays the routine type.
In Program / In Phase / In Instruction

Preserve existing tag values in offline project
When an existing tag has
Operation
set to Overwrite
, this check box provides the option to indicate whether data table-backed tag data values are preserved (check box selected) or overwritten (check box cleared) in an offline project as a result of an import. The check box is selected by default.Keep the following considerations in mind when using the check box:
- Tag data values are never overwritten in the online controller, regardless of the check box state. The check box only affects values written to the offline project.
- Data table-backed tag data values include the value of the tag as well as any force-tag values. The state of the check box (selected or cleared) applies to all data table-backed tags in the import.
- Types for tags that are not data table-backed follow special rules for import and are unaffected by the check box state. Tag configuration data for these types is always overwritten, in both the online controller and the offline project. Tag data values for these tag types are not present in the export file and so are never overwritten anywhere. These types include:
- ALARM_ANALOG
- ALARM_DIGITAL
- AXIS
- COORDINATE_SYSTEM
- ENERGY_BASE
- ENERGY_ELECTRICAL
- Message
- MOTION_GROUP (All tags of any Motion-related type cannot be written while online)
