Handling Duplicate OPC UA Data Sources

OPC UA data sources are identified as duplicates if they contain identical server endpoint values.

If duplicate OPC UA data sources are detected during application import, select one of the following:

Option Description
Use Existing Maintains the data source record that currently exists in Operations Hub. Does not import the duplicate from the file.
Replace Deletes the data source record that currently exists in Operations Hub. Imports the duplicate from the file to replace the deleted record.
Note: This option is enabled only for duplicate data source records sharing the same name and endpoint connection value (URI). Details such as security policy, authentication, etc. may vary in these records.

Duplicate Apps in Operations Hub: During import conflict, if you opt for duplicating the application, the relevant data sources are also duplicated.

To resolve any OPC UA data source server endpoint (URI) conflict when duplicating apps:
  • Select Use Existing to avoid deleting the existing OPC UA record in Operations Hub. This record will not be imported from the file.
  • Select Replace, to replace the existing OPC UA record in Operations Hub with the record from the import file.
The data source records that do not have a conflict get duplicated.
Replace Apps in Operations Hub: During import conflict, if you opt for replacing the application, Operations Hub data source records having the same name as the imported records, are deleted before being replaced with the imported ones.
Note: Any OPC UA data source record in Operations Hub that shares the same name with a record from the import file will get replaced in this scenario. Such records are not considered to be duplicates.
To resolve any OPC UA data source server endpoint (URI) conflict when replacing apps:
  • Select Use Existing to avoid deleting the existing OPC UA record in Operations Hub. This record will not be imported from the file.
  • Select Replace, to replace the existing OPC UA record in Operations Hub with the record from the import file.
The data source records that do not have a conflict get replaced.
Note: Duplicate OPC UA data sources that existed in older versions are not removed after upgrading to 2.1 or later. It is recommended to manually delete such duplicate records, or modify them to use a unique server endpoint connection.
