Version 2026.1.0

Build: 2026.1.0-33

Release date: 10.03.2026

This is a major release of the Prosys OPC UA Browser that includes various new features and improvements.

This release adds the NodeSet Export View and CSV Node Export View for exporting Server AddressSpace to NodeSet XML files and CSV files respectively. The exported NodeSet XML files can be used to generate code with the Code Generator of Prosys OPC UA SDK for Java or imported to Prosys OPC UA Simulation Server (Professional Edition). The exported CSV files provide lists of Nodes in the Objects Folders of Servers and can be used for programmatical processing of the Nodes.

Starting from this version the Browser features a new commercial Professional Edition, which is required to use the NodeSet Export View and CSV Node Export View.

Changes to Common parts

This version of Prosys OPC UA Browser uses Prosys OPC UA SDK for Java version 5.6.0-221.

  • Improved: Product Version, ApplicationUri and other information can be copied to clipboard in About dialog.

  • Changed: The default value of "Preferences > Views > Max Events In Event View" was changed from 1000 to 100.

  • Removed: 32-bit Windows is no longer supported.

Changes to Client

  • New: NodeSet Export View (available in Professional Edition only).

  • New: CSV Node Export View (full use requires Professional Edition).

  • New: "Copy Value as JSON" added to the context menu of Attribute Table for Value Attribute.

  • Changed: File name prefixes must be configured for Data Loggers in Data Views.

Unique file name prefixes must be configured for existing Data Loggers before they can be enabled.

  • Improved: Context menus in various Views include "Navigate to Node" item for navigating to the selected Node in the Address Space Browser.

  • Improved: "mul" locale is supported as the value of "Preferences > General > Preferred Locale".

  • Improved: Times can be configured at millisecond precision in History View and Event History View.

  • Improved: Write Value dialog can be opened from the context menu of Attribute Table for Value Attribute.

  • Improved: Event View and Event History View now sort EventTypes and their Event Fields alphabetically in the "Select Event Fields" dialog.

  • Improved: "Read file" dialog will attempt to determine file extension from the BrowseName of the FileType Node.

  • Fixed: Handle StatusCode Bad_TcpEndpointUrlInvalid when connecting to a Server fails.

  • Fixed: Handle non-numeric values in Data View graphs.

  • Fixed: Changes in Preferences are applied to existing Clients properly.

  • Fixed: "Search for a Node" function now works correctly in cases where the path to the Node includes non-hierarchical References.

  • Fixed: ReferenceDescriptions with missing information, e.g. BrowseName with null Name, are now handled properly instead of triggering an internal error.

  • Fixed: Event View and Event History View now behave correctly when selecting Event Fields that have the same BrowseName from different Event Types.

Fixing this required changing the View configuration format for Event View and Event History View. Thus, old configurations for visibility, sorting and width of table columns can no longer be loaded and defaults will be used instead. The selected Event Fields are loaded from old configurations as usual.

Plus a number of other small changes.
