V13.0.1.0 enhancements

Documentation tag: Release 13.0.1.0

OPC-UA Java stack legacy replaced by Eclipse Milo™ Software Development Kit (SDK)

Following are the key benefits of Eclipse Milo as compared to the legacy stack.

Criteria	Eclipse Milo	OPC UA Java stack
SDK	High-level SDK with APIs for both Client and Server development, handling complex tasks such as session management, subscription transfers, and certificate management.	Only basic framework for communication (serialization, security, and transport).
Development efforts	Allows developers to focus on the application logic rather than implementing the intricacies of the OPC-UA specification, thus significantly reducing development time, and cost.	Building application requires extensive knowledge of the OPC-UA specification parts.
Maintenance and support	Actively developed and maintained open source project with a strong community and commercial backing.	No longer maintained or supported and reached its end-of-life on March 31, 2026.
Real-world use	Extensively tested and proven in the real-world production environments for years, leading to robust and reliable performance.
Java™ SE compatibility	Modern Java versions (Java 11 and higher for the recent versions).	Might be tied to older environments.

Performance improvement

A considerable performance improvement has being observed with following key points.

User interface performance
- The new implementation mainly includes three parts.
  - Eclipse Milo SDK - Used for connection and other server-related operations which boosted the performance.
  - Front-end synchronous optimization - Optimizes small, interactive workloads by reducing latency using minimal payloads and efficient in-memory data handling.
  - Back-end asynchronous design - Handles large-scale operations asynchronously to improve scalability and resource utilization without blocking the UI.
Runtime performance - Reduced memory and CPU utilization observed by using Eclipse Milo SDK.

Search by using "Regular Expression"

Filter client items added in the Input/Read/Write Node, by using flexible pattern matching with regular expressions.

Connect All DataSource

You can now connect to a group of datasources instead of connecting to all the datasources.

You can create a folder and then create group of datasource under this folder. Right-click the folder and select the Connect All DataSource to attempt a connection for only the datasources present under the folder.

Fix pack V13.0.0.2 enhancements

Documentation tag: Release 13.0.1.0

Delete all the items: You can now delete all the added client items in the Integration development perspective by using Delete All. For more information, see Delete All.
Trigger Item List: If you add more than 1100 client items through the Input, Read, or Write node, the Trigger Item List: Showing 1100 Client Item out of <total number of the client items> label gets displayed. Hover over the label to see the list of all the added client items as a tooltip. For more information, see Mapping the properties for the OPC-UA-Input, Mapping the properties for the OPC-UA-Read, and Mapping the properties for the OPC-UA-Write.
suppressDataChangeNotification: A new property suppressDataChangeNotification specifies whether to suppress the information log after deploying the Input Node flow Data change notification observed for items and datasource on the Integration Server console. The default value is false.; Add this property in the server.conf.yaml file with value set as true to suppress the particular information log. For more information, see suppressDataChangeNotification property.
Connect All Datasources: You can now connect to all the data sources in the Manufacturing perspective by using Connect All Datasources. This feature enables eager connection to all the data sources, helping reduce response time when you are working with and adding client items to the Manufacturing nodes. For more information, see Connect All Datasources.

Fix pack V13.0.0.1 enhancements

Documentation tag: Release 13.0.0.1

Dynamic metadata Discovery: The OPC UA Subscriber node can now discover the type of received message with no need to provide it manually. For more information, see Using OPC-UA-Subscriber node.
Manufacturing perspective without connection timeout: You can now use Manufacturing perspective without waiting for connection timeout. For more information, see Setting the environment variable for JSON files data storage.
View Data Sources connection state: The newly created data source in the DataSources view displays Connected (Green) or Disconnected (Red) connection status. For more information, see What to do next section in the Creating a data source.
