Welcome to the WinCC OA Hub – a public repository that provides practical tools, helpers, and ready-to-use examples to make development with SIMATIC WinCC OA easier, faster, and more effective.

- Help integrators and users speed up development.
- Share best practices in UI design, scripting, and architecture.
- Showcase integrations and automation approaches.
This repository serves as a curated collection of public helper tools and application examples, including:
- Sample WinCC OA projects (e.g., dashboards, libraries, integration adapters)
- Snippets and scripts in CTRL, CTRL++, JavaScript, and other supported languages
- UI components, scripts, libs, snippets, ...
All content is:
