8.02.00

September 2025

New Features

  • Optimized payload hadling in acquisition engine:
      The acquisition engine now supports payload compression, enabling up to 500 tags per payload while maintaining the 22KB size limit. This enhancement reduces message volume and network load, especially in high-frequency configurations. Compression is handled on the edge gateway; decompression occurs in the server-side data processor worker module [SWCDMPC-7186].
  • OPCUA connector - subscription mode feasibility validation:
    Subscription mode support for OPCUA is under feasibility testing using the acquisition engine. When enabled, the connector receives updates only on data changes, improving responsiveness and reducing reliance on polling intervals [SWCDMPC-8883].
  • Data Export V2:
    This enhancement allows you to export tag data to cloud storage locations, such as AWS S3 and Azure Data Lake Storage Gen2, on both scheduled and on demand basis. You can also configure for an on prem location or file share by mounting to a path. This feature enables users to write data directly to cloud destinations from the portal, schedule recurring jobs for real-time uploads, export historical data on demand, save jobs with predefined tag sets for quick execution, and monitor job execution status-including history and error logs-through the portal interface [SWCDMC-7129].
  • Language preference persistence:
    You can set your preferred language on your profile page and used as your default preference. When you sign in, the system displays this language by default. You can change it anytime during your session [SWCDMC-8054].
  • Edit Dashboard V2:
     Time-series widgets now offer a simplified, user-friendly visualization in both the dashboard and widget configuration. You can enable this feature through environment settings and apply it at either the project level or the environment level. Users can now design dashboards with project- or environment-specific settings, including chart type, range, and axis selection [SWCDMPC-8060].

Enhancements

  • Improved event ingestion throughput:
    The product now achieves event ingestion throughput of 200events/sec and event knowledge graph created at 60events/min.
  • Knowledge Graph
    feature is now compatible with flexible projects.
  • Enhanced Backup Data handling in Data Diode RX:
    Backup data is now routed to a dedicated topic and processed by a separate worker, ensuring that live data handling remains uninterrupted. Previously, both live and backup data were routed to the same topic, which could cause delays. With this change, each data stream has its own topic, improving processing efficiency and system responsiveness. File operations within the RX module are optimized, and event logging has been added to improve visibility during backup transfers.
  • OPCUA Connector enhanced with security and certificate support:
     The OPCUA data connector now supports username/password authentication, security modes (None, Sign, Sign and Encrypt), and security policies including Basic256Sha256, Basic256, Basic128Rsa15, and Aes128Sha256RsaOaep. Certificate-based authentication is supported across Windows, Ubuntu, CentOS, and RHEL9 agents.
  • History pages for bulk operations and bulk updates of asset hierarchies:
    History page has been introduced in asset hierarchies, which enables users to track previous upload attempts and monitor changes over time. Users can perform bulk updates, download existing hierarchy data for reference, and access history pages showing prior upload activities. Audit logs capture upload status, user details, and line-level error feedback to support troubleshooting and ensure compliance.
  • Tag Browser-Hierarchy-based pagination:
    The platform introduces a new way of selecting tags, called the
    Tag Browser
    , to simplify traversal and selection across hierarchies.
    • Provides an intuitive and efficient way to browse and choose tags.
    • Integrated into
      Data Explorer, Data Import, and Data Export v2
      .
    • Enhances productivity by reducing complexity in tag selection.
  • Performance improvements:
    Optimized system performance to deliver faster load times and smoother interactions across key modules. Enhanced responsiveness for large data operations to improve overall user experience.
  • 64 bytes data types for Modbus Data Connector:
      Added support for 64-bit data types in the Modbus Data Connector. This enhancement improves compatibility with a wider range of industrial devices and enables more precise data handling for high-resolution measurements.
  • Unified semantic model projects - Parameter bulk upload optimization:
    Bulk upload of parameter data for graph model projects has been optimized for improved performance and reliability. This enhancement ensures faster implementation with reliability and easy execution for large scale projects.

Fixed Anomalies

  • Assets incorrectly visible in Asset Explorer:
    Resolved an issue where assets appeared in the Asset Explorer page for users who did not have access permissions.
  • App cloning failed due to existing module:
    Fixed an error that occurred when users attempted to clone an app, which previously failed with a “module already exists” message.
  • Associated project list missing in Workspace:
    Addressed a problem where the Workspace view did not display the associated project list as expected.
  • Access token permissions:
     Users were able to delete or create access tokens without the required create/delete permissions in their user role. This has been corrected.
  • Asset model deletion:
     Users were unable to delete asset models; this functionality is now working as expected.
  • Sensor data connectors:
     Deletion of blocks was not functioning properly and has now been fixed.
  • Rollup aggregator:
     Rule function was not working and has been restored.
  • Analytical model:
     Reuploading GraphQL files was not updating the analytical model; this has been fixed.
  • Scheduled plugin reports:
     These were failing and are now functioning correctly.
  • Widget plugins in Data Explorer:
     In fixed level projects, widget plugins were not selectable; this issue has been addressed.

Expected Behaviours

  • Tag Browser:
    Once tags are selected from the Tag Browser, they will not appear as pre-checked when the Tag Browser is reopened.
    • Duplicate selections are automatically handled to avoid repetition.
    • The underlying page continues to display the complete list of all selected tag details.

Known Issues

  • When an equipment is reassigned from one asset model to another, rules linked to the previous asset model are not automatically removed. Users must manually re-save the rules to clear the earlier associations.
  • The unified semantic model project doesn’t support the parameter representation feature for user roles in this release.
  • Data & asset problems:
     Asset Type not saving, AG Grid filtering issues, Data Mapping errors, and Modbus server data fetch failures.

Known Limitations

  • Edit Dashboard V2
     supports only time series widgets.
  • Data Explorer:
    • Maximum 10 workspaces per worksheet.
    • Maximum 30 tags per workspace in Data Explorer.
  • Data Import:
      limited to 50 tags per import.
  • Data Export V2:
    limited to 1,000 tags per export.
  • Auto Patch feature:
    Currently supported only in Online environments.
  • Modbus Server Writeback feature:
    • Minimum writeback frequency is 10 seconds.
    • Bulk write operations for tags are not supported.
  • High availability or auto-scaling for graph database server.
  • Higher latency for events to appear on the platform when knowledge graph stack is installed. This is due to the slowness in ingestion of events to the graph database (Current measured throughput - 60 events/min).
  • Entity deletion from Analytical Data Model screen:
    User cannot delete already created entities from new graphql upload. In current version it only removes the link to the existing nodes.
  • Catalog feature:
    Currently supported for Asset Model, Apps, and Dashboards with some limitations. After cloning apps and dashboards from the catalog, tag mapping and certain configurations will need to be updated manually.
  • Hierarchy level access restriction is supported only at hierarchy levels. The unified semantic model projects list equipment but doesn’t support the access restrictions at hierarchy level.
  • The bulk upload feature supports creating hierarchies but doesn't allow editing or deleting existing ones.
  • More than 25 concurrent users operating on the event explorer screens (graph view) may experience slowness in data lading.
  • Knowledge graph feature cannot be enabled in more than 10 projects/tenants in one installation of Unifytwin.

Removed Features

  • The Alarm Tree Widget has been removed from the Dashboard widget creation screen.
  • The Tree-View option for the Alarm Tree Widget has also been removed from Asset Explorer.
