Re-import IEC61850 Objects in Logical and User Defined Views

When re-importing IEC61850 data in Logical and User Defined Views using a CSV file, the re-import applies only to the IEC61850 logical devices referred to in the CSV file.

The re-import operation is done in a similar way as the import, except that the existing IEC61850 logical device objects are updated as follows:

• The new logical device entries in the CSV file are added to the existing logical device entries in the System Browser, if the Delete unselected items from the views check box is not selected.
• If the device description of a logical device is modified in the CSV file, with no change to the existing paths of LogicalHierarchy or UserDefinedHierarchy, then the existing device description of the logical device is updated with the new description, if the Delete unselected items from the views check box is not selected.
• If the device name or device description of a logical device is modified in the CSV file, with no change to the existing LogicalHierarchy or UserDefinedHierarchy paths, then the modified device nodes are added as siblings of the existing logical device nodes in the System Browser, as long as the Delete unselected items from the views check box is not selected.
• If the device name or device description of a logical device is modified in the CSV file, with no change to the existing paths LogicalHierarchy or UserDefinedHierarchy paths, andthe Delete unselected items from the views check box is selected, then the existing logical device nodes below the hierarchy path are deleted and the device nodes in the CSV file are added. In this case, only the logical device nodes are deleted; the hierarchy paths are not deleted.
• If the device name or device description of a logical device is modified in the CSV file, the existing path of LogicalHierarchy or UserDefinedHierarchy is modified, and the Delete unselected items from the views check box is selected, then the existing device nodes below the previous hierarchy path are deleted and the device nodes with new hierarchy paths in the CSV are added. In this case, only the logical device nodes are deleted; the hierarchy paths are not deleted.
• If the existing LogicalHierarchy or UserDefinedHierarchy path is modified in the CSV file, the Delete unselected items from the views check box is selected, and there no change to the device name or device description, then the existing device nodes below the previous hierarchy path remains unchanged and the device nodes with new hierarchy paths in the CSV are added.
• A logical device, for example, IEC61850 device1 associated with Device Connection IEC61850 Device Connection 1 is present in the logical view. On re-import, if there is no change to the name of the logical device entry in the CSV file, but the name of the Device Connection changes to IEC61850 Device Connection 3. In this case, #1 will be appended to the logical device name of the second entry in a logical view or user defined view. On subsequent re-imports, the number equivalent to #n+1 is appended to the logical device name.

In situations where there are two device nodes with the same names, the Importer performs the parsing operation using any of the following methods:

• If a node with the same name does not exist, then the node is created.
• If a node with the same name referring to the same data point exists, then only the description is updated.
• If a node with the same name referring to a different data point exists, then a new node with name_#n is created.
