# T-IA Connect

> The API Bridge & AI Connector for Siemens TIA Portal

T-IA Connect is a native Windows desktop application that wraps the Siemens TIA Portal Openness API into a modern REST API. It allows engineers, DevOps teams, and AI agents to programmatically control TIA Portal — creating projects, generating PLC code (SCL/STL), compiling, exporting, and managing devices — without opening the TIA Portal GUI.

## Key Features

- **REST API for TIA Portal**: Full HTTP/JSON interface to TIA Portal Openness (projects, devices, blocks, tags, compilation, export).
- **AI Code Generation**: Built-in integration with LLMs (Claude, ChatGPT, local models) to generate SCL/STL code from natural language descriptions.
- **MCP Server**: Model Context Protocol server allowing AI agents (Claude Desktop, Cursor, etc.) to directly interact with TIA Portal.
- **Headless Mode**: Run TIA Portal entirely in the background via CLI (`--headless`), perfect for CI/CD pipelines.
- **Multi-Version Support**: Works with TIA Portal V16, V17, V18, V19, and V21.
- **Plugin SDK**: Extend T-IA Connect with custom C# plugins.

## Supported TIA Portal Versions

- TIA Portal V16
- TIA Portal V17
- TIA Portal V18
- TIA Portal V19
- TIA Portal V21
