Sample applications

This repository contains a large collection of platform-independent samples that demonstrate the stack's client, server, PubSub, companion-model, and developer-tooling APIs. Each sample has its own README.md with build and run instructions. If you are new to the SDK, start with the minimal samples.

Minimal samples

Getting started runs the Minimal Boiler Server and the Minimal Client together.

Minimal Boiler Server — minimal Boiler-model server with the fluent state-machine builder; Native-AOT publishable.
Minimal Client — hosted client that discovers a secure endpoint of the Minimal Boiler Server, creates a subscription, browses, and reads; Native-AOT publishable.
Minimal Calc Server — minimal server built on the source-generated NodeManager pipeline and Calc model.

Reference applications

Console Reference Server — the certified reference server with Quickstarts, CTT, and Mono configurations. It also ships as a Docker container.
Console Reference Client — cross-platform reference client demonstrating sessions, subscriptions, browsing, and method calls.
Console LDS Server — a standalone Local Discovery Server built on Opc.Ua.Lds.Server.

PubSub samples

Console Reference PubSub Client — one executable with publisher, subscriber, and external external-server-adapter modes across the supported transport profiles.
SecureChannel PubSub (experimental) - brokerless UADP/JSON over dedicated or shared UASC, in one or two processes, with byte/value validation, live revision and optional Session authorization.

Experimental Data Channel samples

These .NET 10 applications use the rewritten Data Channels protocol. Configured dedicated/native modes create no Session or optional address-space model. Native modes require the reviewed assets described in their READMEs; there is no alternate-carrier fallback.

Streaming - finite complete-message runs over all four carriers, payload role reversal, live revision and a shared-channel Read/Publish benchmark.
Audio - complete opaque PCM messages, finite headless WAV output and explicit Windows playback.

Companion-model samples

Generic recycling simulation — one durable causal coordinator and ten process views with typed OPC UA coordination, native companion equipment, material genealogy and read-only committed measurements. Its optional operator console walkthrough covers browser inspection and role-limited controls with screenshots and an animated tour. The guide distinguishes synthetic simulation from calibration, original-source parity and formal companion certification.
Pump Device Integration Server — Device Integration Part 100 server using Opc.Ua.Di.Server's fluent builder.
AMB Server — OPC 10000-110 Asset Management Basics with AddAssetManagement next to AddMachinery: a cooling pump and a flow sensor (Device Integration devices) and a hydraulic press (a Machinery machine) as assets with configurable AssetIds, health alarms with root causes, maintenance activities, documentation links, locations and persistence, and a simulation that raises alarms and moves the maintenance on.
AMB Client — discovers every asset with AmbClient, prints snapshots and the location hierarchies, adds and removes a documentation link, and streams health alarms and maintenance activities.
Minimal Robot Server — OPC 40010 Robotics with independently configurable RSL/GPOS motion and live OpenUSD transforms.
Intent Enabled Robot — collaborative arm exposing task-level Robot Intent motion verbs, Part 10 program lifecycle, missions, command authority, and safety-aware refusal.
Intent Viewer Client — click a target in an OpenUSD viewport and watch the arm execute the resulting intent; it also runs headless.
Bin Picking Cell — Robot Intent, Vision, an eye-in-hand camera, and an in-address-space OpenUSD scene in one reference cell.
Bin Picking Client — closes the Vision-to-Robot-Intent loop, with optional MCP hosting and an OpenUSD viewport.
Visual Inspection Cell — hosts Vision, AI Model Management, ISA-95 Job Control V2, and an operator dialog for deterministic machined-bracket inspection.
Visual Inspection Agent — drives the inspection loop with typed clients, routes inference through deployment Invoke, applies recipe verdicts, schedules allowlisted jobs, and records operator ground truth.
AI Model Management sample — ModelManagementServer publishes the draft AI Model Management catalogue and routes inference; ModelManagementClient discovers deployments and exercises the Methods.
Machine Vision server and client — released OPC 40100-1/-2 in Machinery, with recipe/file workflows and a shared draft/native inspection engine.
MachineTool and WMTP — separate or combined MachineTool/peripheral hosting, independent simulated instances, retained and modern production, remote files, measurement configuration and record workflows.
GMS server and client — native systems, qualification, environmental conditions and typed result/characteristic/correction workflows.
AutoID server and client — a simulated OPC 30010 RFID reader with scans, tag memory access and scan/presence events.
Cranes and Hoists — Robotics-derived topology, acquisition quality and authorized simulated limit requests.
Combined companion suite — MachineTool, WMTP, GMS, CranesHoists and MachineVision on one DI/Machinery owner, with isolated instances and a bounded real-session self-check.
Minimal ISA-95 Server — hosts the OPC-10030 ISA-95 Common Model with OPC-10031-4 Job Control V1 and V2, using the typed common-model builder and in-memory Job Control provider.

OpenUSD site composition

Generator Server — simulated generating sets with datasheet-driven behavior and independent OpenUSD twins.
Site Composition Server — federates the pump and generator servers into one live OpenUSD site.
