Where Rung earns its place on the plant floor.

Walkthroughs of the incidents OT engineers actually face — and how Rung compresses hours of manual digging into minutes, running locally and read-only by default.

Demo · full walkthrough
Watch Rung troubleshoot a live fault, start to finish.

One scripted session covering the mechanics that matter: plain-language diagnosis, an approval on the one step that changes something, a mid-session privacy-level switch, and a verified fix.

Energy · power generation
The historian went dark at 2:14 a.m. It was back before shift change.

A control engineer diagnoses and resolves a live Aveva Historian outage on a power plant's transformer bank — context, the actions Rung took, the result, and what it would have cost without it.

Discrete manufacturing · packaging
The engineer who wrote this logic left three years ago. Rung explained it in six minutes.

A control engineer explains undocumented Rockwell ladder logic and traces a signal across two controllers on a packaging line — without an OEM site visit, and without ever connecting to a live controller.

Discrete manufacturing · fleet-wide
Nobody had a current PLC inventory for this site. Rung had been building one all year.

A control engineer turns a capital-planning deadline into a prioritized, fleet-wide PLC obsolescence plan — using a site inventory Rung already built during ordinary troubleshooting work, without a plant-wide audit.

Each walkthrough is grounded in the failure modes Rung's troubleshooting playbooks are built around, not a specific customer's data — we'll link real case studies here as design partners come online. Have an incident you'd like to see one built around? Tell us.
