Import/Paste Configuration Dialog - Parameters and Local Tags Definition Overview
Use this dialog box to view Parameters, Local Tag definitions, and their properties. All settings in this dialog box are read-only and cannot be changed.
Tag references are represented in the Import Content by the Tags item found under the References folder. When the Tags item is selected, the Details pane displays the tag references in the import content. The list includes any tags directly referenced by any imported logic and tags (via Alias For).
If the operation on a tag is set to use the existing tag in the project then the Scope, Alias For, Data Type and Description fields show the values from the tag in the project and appear dimmed. Otherwise, these fields display the values from the import file.
Note that local tags do not display if the instruction is source protected Add-On Instruction. To learn more about source protection, see About Source Protection.
The imported Add-On Instruction’s Parameters and Local Tags displays in the Import Content when you select the Parameters and Local Tags item found under the imported Add-On Instruction’s item. When you select Parameters and Local Tags, the Details pane displays the Parameters and Local Tags definitions grid.
Parameters
Row Header
The leftmost part of the grid, provides an indication of the condition of the component that was imported, as follows:
 | Indicates why the component needs attention. Hover the cursor over the red flag icon and a tool tip displays and indicates the reason for the message. |
 | Indicates a safety warning. |
Import Name
Displays the name of the component as read from the import file.
An import name does not display for any Parameter and Local Tag that exist in the project but not in the import content.
Operation
Displays the operation for each tag dependent upon the operation selected for the Add-On Instruction being imported:
- Create - for Parameters and Local Tags that exist in the import content, but not in the project and the operation for the parameter and local tags are set to Create or Overwrite.
- Discard - for Parameters and Local Tags that exist in the import content, but not in the project and the operation for the parameter and local tags are set to Discard or Use Existing.
- Delete - for Parameters and Local Tags that exist in the project but not in the import content and the operation for the parameter and local tags are set to Overwrite.
- Use Existing - for each colliding Parameter and Local Tag and the operation for the parameter and local tags are set to Use Existing.
- Overwrite - for each colliding Parameter and Local Tag and the operation for the parameter and local tags are set to Overwrite.

Import Configuration Operations
.Final Name
Displays the contents of the Import Name field.
The Final Name is blank if the Operation field is set to Discard.
In cases where the operation is delete, this field contains the name of the deleted tag or parameter.
Usage
Displays content depending upon the content in the Operation field.
Operation | Usage Column |
Undefined | Displays nothing |
Use Existing or Delete | Displays the usage of the Parameters and Local Tags in the project |
Overwrite or Create | Displays the usage of the Parameters and Local Tags as it is read from the import file |
Blank (read-only) | Displays nothing (for members of a Parameter or Local Tag that are displayed only because they have member or bit-level descriptions defined in the import file). |
Alias For
If a tag is an alias, the Alias For column displays the target tag (the tag that contains the datatype definition for an alias tag). For Add-On Instruction definition, only Input and Output tags can alias Local Tags; Local Tags and InOut tags cannot alias another tag.
Data Type
Displays the data type of the Parameters and Local Tags, as read from the import file if the Parameters and Local Tags Operation is set to Create, Overwrite, or Discard.
If the Operation field is set to Use Existing or Delete, it displays the data type of the Parameter or Local Tag in the project.
If the Tag is an alias Tag, or if the row represents a member of an expanded tag, this field is blank.
Description
Displays the description of the Parameter or Local Tag.
External Access
This column indicates whether the tag has Read/Write, Read Only, or no access (None) from external applications such as HMIs. You cannot modify this column. For more information about External Access, see About External Access.
Constant
This column indicates if logic is prevented from writing values to the associated tag or parameter. If a logic routine tries to write to a constant tag, the routine will not verify.
Messages
Pay particular attention to warnings that appear in the area below the grid.
