## Overview

This repository is a short set of notes for participants in the 2026 Siemens Cup intelligent-manufacturing general-knowledge event, not an application. Its documented workflow is to consult the notes, check fixed-IP reachability with ping, and test HMI access using administrator or guest credentials. The only repository artifact shown is README.md, so the diagram reflects documented guidance rather than an inspected implementation.

Main entry points: [`README.md`](https://github.com/qiufen223/cimc20th-2026-general-knowledge/blob/main/README.md) (Competition notes)
