Full OPC UA Protocol Simulation β€” Live Factory Metrics, Zero Hardware Required

The TWAIN OPC UA endpoint at https://twainopcua.compliancetest.net delivers a fully-operational OPC UA server simulation environment purpose-built for TWAIN Innovation Cloud developers. Start a simulation session with a single API call, then stream live factory metrics β€” node counts, active sessions, subscriptions, security posture, performance diagnostics, and data change volumes β€” all in real JSON over HTTPS.

As a registered TIC participant you receive a personal API key enabling authenticated access to all three endpoints. The live metrics dashboard visualises all metrics as a heat-scored card grid with click-through modals explaining every metric's description, use case, expected range, and OPC UA standard reference β€” ideal for learning the protocol or demonstrating an integration.

Whether you are building an industrial IoT monitoring platform, a TWAIN document scanner integration that uses OPC UA for device discovery, a billing engine for metered factory data services, or a compliance audit tool for IEC 62443 / IEC 62541 certified deployments β€” this endpoint gives you live, structured OPC UA data to work with immediately.
