Re-import IEC61850 Objects in Management View

When re-importing IEC61850 data using a CSV file, the re-import applies to the IEC61850 device connections and logical devices referred to in the CSV file. The re-import operation is done in a similar way as the import, except that the pre-existing IEC61850 objects are updated as follows:

• Creating new device connections and logical devices.
• Updating existing device connections and logical devices.
• Deleting existing device connections and logical devices (only if the Delete unselected items from the Views check box is selected). Deleting the IEC61850 device connections and logical devices results in deleting them from all the hierarchies in other views.

This operation also causes the Management View hierarchy to update with any new objects that are added or removed from the CSV file.

The import process deletes any IEC61850 device connections and logical devices that are no longer present in the CSV file (only if the Delete unselected items from the views check box is selected).

During re-import, the IEC Importer prevents changing an already imported IEC logical device in the Object Model (OM) instance. For example, during import, if an instance of an IEC_Device Object Model is created with the name IEC_Device_1, then the Importer will report an error if you specify an instance with the same name (IEC_Device_1). but with a different Object Model during re-import.

Re-Importing Alias Information

The following information with respect to re-importing the data from the Alias column of the CSV file applies when re-importing objects from any of the views (physical, logical, user-defined).

• If the alias information in the IEC61850 CSV file is not assigned to any node in the system, then the alias can be assigned to the IEC61850 Device Instance node or IEC61850 Logical Device node.
• If the alias information in the IEC61850 CSV file is assigned to any node in the system, then the system checks to see if the name of the node to which the alias is assigned and the name of the node associated with the IEC61850 Device Instance or IEC61850 Logical Device are identical or different. If both nodes have identical names, then the alias information is imported. However, if the names of both the nodes are different, then the alias information is not imported since the same alias cannot be assigned to two nodes in the system. In this situation, a message informing you the reason for the import failure displays in the Preimport Log File dialog box.
