Release Notes → Update 5c → Update 5c - Detailed Release Notes

FrameworX 10.1 Update 5c — June 22, 2026

OPC UA

• Structured-type UDT tags over ExtensionObject now decode correctly — OPC UA devices that expose UDT tags as ExtensionObject — including CODESYS and WAGO PLCs — now read all struct members with accurate values at runtime. Nested structures are fully supported.
• Data Explorer drills into nested struct nodes — the OPC UA Data Explorer now expands struct hierarchies beyond the root level, making it straightforward to inspect and map deeply nested UDT members from any OPC UA server.
• TagProvider browses nested struct members — the OPC UA TagProvider now exposes sub-members of nested struct nodes, completing full struct-hierarchy visibility from tag browsing through to runtime.
• OPC UA Simulator enforces configured security policies — the built-in OPC UA Simulator now applies exactly the security policies configured, with no silent fallback to unsecured endpoints.
• Address space commas preserved — node identifiers containing commas in the OPC UA address space are now stored and used correctly in Devices configuration.
• CertificateType — Custom option available — the CertificateType field on OPC UA devices now includes the “Custom” option, enabling managed certificate workflows for deployments that require it.
• Custom certificate trust — no repeat prompts — once a server certificate is trusted with the Custom policy, subsequent connections proceed without re-prompting. The certificate trust prompt in the import wizard is also shown only once.
• Tag import resilience — OPC UA tag import completes successfully even when the server is intermittently unreachable or the configuration references a legacy format.

AI Integration — MCP and AI Authoring

• Headless solution execution for automated testing — AI agents and CI pipelines can now start a solution headlessly with its full web client available, enabling end-to-end automated testing without a visible desktop.

• Partially-configured rows from automation — AI agents can create mid-commissioning (partially configured) rows explicitly, supporting incremental provisioning workflows.
• Display clipboard across solutions — AI Designer can now copy and paste Display content between different solutions using new clipboard export and import tools.
• Author display configuration completely from automation — legend, connections, chart orientation, child-display links, and themes can all be authored from automation tools without opening the Designer UI.
• Verify dialog content in automated tests — dialog content and prompts in automated Designer tests can be inspected without rendering them, enabling headless CI validation of dialog-driven workflows.
• Validate electronic-signature workflows from automation — electronic-signature and security workflows can be exercised safely through automated tests, with full audit-trail fidelity.
• Local AI — tag property read coverage — the Local AI Chat can now read all tag properties, including type, reference tag, and startup value.
• LocalAI shipping configuration — the SolutionCapabilities dialog and ModelOptions defaults now reflect the Local AI shipping configuration, ensuring out-of-the-box behavior matches documentation.
• UNS Asset Tree folders — Description field — asset folder descriptions can now be set and updated through AI tools, completing the metadata round-trip for UNS assets.
• Rendered color reading — AI tools can now read the actual rendered color of display elements at runtime, enabling color-aware automation and visual validation.
• Imported solutions open their own main page — solutions opened via AI tools now navigate to their own main page; long builds report progress rather than timing out silently.
• Browser auto-launch on web-client solutions — starting a .NET 10 solution that includes the web client now automatically opens the browser, matching the interactive Designer experience.
• Write tools report accurate completion status — MCP write tools no longer return success when the Designer was busy or disconnected at the time of the call.
• Misspelled field warning on writes — display and script writes that include an unrecognised field name now surface a warning, preventing silent data loss from configuration typos.
• Query and script content integrity check — saved queries and script content are verified against what was sent; a notice is raised when the editor internally overwrote the intended value.
• Dataset query SQL integrity — dataset queries created or edited through AI tools now reliably save exactly the SQL that was provided. JSON workspace imports no longer corrupt tag references inside SQL text.
• ConsoleMCP — element type validation — write_objects rejects unknown display element Type strings; verify_workspace flags elements whose Type is not in the element catalog, preventing silent misconfiguration.
• ConsoleMCP — protocol and element schema completeness — list_protocols now returns Point Address schemas for DataHubService and LabView; list_elements eliminates duplicate Polygon/Path shape-alias entries.
• ConsoleMCP — workspace isolation — workspace stop and auto-close actions target only their own runtime instance, never affecting other open workspaces.
• ConsoleMCP — trailing backslash fix — create_solution_file no longer hangs when the output path ends with a trailing backslash.
• AI Runtime connector — local runtime discovery — the AI Runtime connector reliably locates locally running runtimes across all configurations.

• User-account fields in AI tools — security user fields such as Blocked are now fully accepted by the AI authoring tools, completing the security-user schema.
• Display Description persists on update — a display’s Description field is now correctly saved when an existing display is updated through the AI Designer.
• verify_solution_file — Script Expression inventory — the tool now inventories Script Expressions and correctly finds solutions stored in non-default folder locations.
• Element round-trip fidelity — re-writing a normalized display through ConsoleMCP now correctly reports a change, enabling round-trip diffing and idempotency checks.
• Responsive canvas — element-lock behavior documented — element-lock behavior in the AI Designer context and Display schema is documented, ensuring consistent automation results on responsive-canvas displays.
• AI Chat — Secure Gateway routing — the Chat panel shows replies correctly when LLM traffic is routed through a Secure Gateway egress server, supporting air-gapped and cloud-hybrid deployments.

Visualization and Displays

• Windows service path hardening — service registration for TStartupService, TWebServices, MQTTBroker, and Hardkey now uses quoted executable paths, eliminating the unquoted service path vulnerability.

Designer

• Symbols imported with complete graphics — symbols imported from the library or from XAML files are saved with their full graphical content intact. Symbol loading continues to work correctly after import.
• Visual Query Builder — multi-language support — the embedded Visual Query Builder loads the database schema tree correctly regardless of the active Designer UI language.
• Ontology export/import round-trip — ontology names survive an export/import cycle without modification; malformed ontology files are rejected safely without corrupting the solution.

• Industrial Ontology import — JSON-LD (.jsonld) and Turtle (.ttl) formats are now importable, completing import/export format symmetry: all four formats (RDF/JSON, N-Triples, JSON-LD, Turtle) are available in both directions.

New Features and Enhancements

• OIDC / OAuth2 — SSO Sign-In Button: The SSO entry-point button on the client logon surface is now active. Operators see a direct single sign-on option alongside the standard login; identity provider sessions are managed transparently through the configured Keycloak, Auth0, Entra ID, or login.gov provider.
• AI Chat — Multi-Provider and Richer Conversations: AI Chat now supports multiple simultaneous providers — Local AI, Anthropic Claude, OpenAI GPT-4o, Google Gemini, and Azure OpenAI — with the active provider selectable per conversation. The conversation experience adds streaming responses, code-block rendering with syntax highlighting, and one-click copy, making AI-assisted operator workflows more productive.
• Local AI — Simplified Setup and SecureGateway Routing: A guided first-run wizard streamlines Local AI service configuration. SecureGateway routing enables AI endpoints hosted in the cloud to be accessed through the FrameworX gateway, simplifying hybrid and air-gapped deployments.
• Runtime REST API — Tag Writes and Standardised Errors: The Runtime REST API gains POST /tags/{name}/value for writing tag values, complementing the existing read and history capabilities. All REST endpoints now return RFC 9457 Problem Detail error responses, providing consistent, machine-parseable error handling for IT integrations.
• SiemensPlus — Cross-Platform Siemens Driver: Update 5b introduces SiemensPlus, a new Siemens driver built on a modern API foundation with native cross-platform support — running on Windows, Linux, and Docker-hosted FrameworX deployments. Existing solutions using the original Siemens driver continue to operate without any changes; the legacy driver remains fully supported for backward compatibility.
• Combo Box and List Box — Live Enumeration Source: Combo Box and List Box controls can now source their data items directly from a Tag enumeration definition. Values and display labels update dynamically as the enumeration changes — keeping dropdowns in sync with process configuration without manual maintenance.
• Linear Gauge — Fully Dynamic: Fill colour, minimum, maximum, and all range-band boundaries on the Linear Gauge are now bindable to tags. Gauge appearance responds live to runtime value changes, enabling process-aware visualisations without scripting.
• Security Secrets — At-a-Glance Credential Health: The Security Secrets dialog is redesigned around operational clarity: each secret shows its current status (Valid / Invalid / Expired), expiry date, and a Rotate action — giving administrators a single, actionable view of credential health.
• Industrial Ontology — Faster Large-Scale Imports: Large ontology imports are significantly faster, with reduced memory usage during RDF graph traversal. Deployments with complex or extensive ontology definitions see meaningful performance improvements on import and reload.
• Device Nodes — Category Field: A new Category field on Device Nodes enables grouping and filtering in the Device Explorer tree, improving navigation and organisation in solutions with large numbers of devices or complex architectures.
• Solution Center — Offline License Activation: Air-gapped deployments can now activate FrameworX licenses without internet connectivity. A QR-based activation code exchange allows a connected machine to generate and transfer the activation to the isolated target machine.
• JSON Import/Export — More Control: Exports support filtering by tag type, enabling targeted round-trips for specific asset categories. Import correctly handles circular UserType reference structures that previously required workarounds.

FrameworX 10.1 Update 5 — Released May 26, 2026

Platform Foundation

.NET 10 (LTS) Runtime
FrameworX 10.1 Update 5 ships on .NET 10 Long-Term Support — Microsoft’s latest and most performant runtime baseline. Every server deployment, Web Contents target, and Designer Web host benefits automatically. The upgrade is handled entirely by the installer; no solution changes or manual steps are required. .NET Framework 4.8 continues to be supported for environments where it is needed.

Within-Major Compatibility
Every 10.1.x solution opens and runs on Update 5 without migration, code changes, or rework. Solution Center’s multi-version routing allows 10.1.4 and 10.1.5 installations to coexist side-by-side during phased rollouts.

Platform Reliability

• Designer–Runtime IPC applies a bounded timeout, so a slow device driver can never drop an active Designer session.
• Backend services maintain uninterrupted operation in unattended deployments.
• Protocol driver file lookup is case-insensitive across Windows and Linux/Docker hosts, enabling seamless cross-platform deployments.

Enterprise IT, Security, and Deployment

OIDC / OAuth2 Single Sign-On
FrameworX now integrates with enterprise identity providers through OIDC/OAuth2, with out-of-the-box support for Keycloak, Auth0, Microsoft Entra ID, and login.gov. Per-provider configuration dialogs, LDAP dispatch, and industry-standard JWT validation (RFC 8725) are all managed by the runtime. The SSO sign-in button on the client logon surface is available from Update 5b onward.

Runtime REST API v1.0
A new data-plane REST API (port 3101+) exposes live tag values, alarm state, historian queries, and aggregated history — purpose-built for enterprise IT integrations and partner systems. Authentication is via Bearer-GUID. Update 5b adds tag write support.

SolutionCenter API v1.0
A management-plane REST API (port 10108) covers the full solution lifecycle: solution management, file operations, license control, and machine-level administration. Secured with JWT/OIDC and documented via a published OpenAPI 3.0 specification.

Kubernetes-Native Deployment
TServer and TWebServices expose /health and /ready HTTP endpoints fully compatible with Kubernetes liveness and readiness probes, making container-native and cloud-hosted FrameworX deployments first-class citizens.
