概览

What is T-IA Connect (Siemens TIA Portal)?

T-IA Connect (Siemens TIA Portal) is a GenAI bridge that securely connects large language models to Siemens TIA Portal. It generates deterministic PLC logic (SCL/ISA-88) from natural language using Sovereign GenAI models, enabling engineers to create and compile PLC blocks via chat.

How to use T-IA Connect (Siemens TIA Portal)?

Install T-IA Connect from its website, then configure the MCP server in your AI assistant’s claude_desktop_config.json pointing to TiaPortalApi.App.exe with the --mcp flag. Alternatively, launch the core engine in headless mode (--headless) to use the REST API at http://localhost:9000/ for direct HTTP calls.

Key features of T-IA Connect (Siemens TIA Portal)

120+ MCP tools for full TIA Portal orchestration
Deterministic SimaticML XML builder prevents AI hallucination
Sovereign AI integration with European-hosted models (Qwen3-Coder-30B)
Headless operation — no GUI or WPF window required
Supports TIA Portal versions V17 through V21
Compiles PLC blocks directly from chat in under 30 seconds

Use cases of T-IA Connect (Siemens TIA Portal)

Generate PLC blocks (FB, FC, OB) from natural language descriptions
Automate testing with PLCSim Advanced via chat commands
Browse and understand existing PLC project structure without manual navigation
Compile TIA Portal projects headlessly from CI/CD pipelines

常见问题

What are the prerequisites for using T-IA Connect (Siemens TIA Portal)?

You need T-IA Connect installed, Siemens TIA Portal V17, V18, V19, V20, or V21, and a TIA Portal project file (`.ap17` / `.ap18` / `.ap19` / `.ap20`).

How does T-IA Connect (Siemens TIA Portal) ensure deterministic PLC logic?

The AI reasoning step is followed by a deterministic C# engine that builds strict SimaticML XML, preventing AI hallucination. The core engine remains private and proprietary.

What AI models are used and where are they hosted?

The system uses Qwen3-Coder-30B-Instruct via OVHcloud AI Endpoints, ensuring sensitive PLC logic never leaves the European Union.

Can T-IA Connect (Siemens TIA Portal) be used without a graphical interface?

Yes. Headless mode launches a REST API on `http://localhost:9000/` without any GUI, allowing fully automated, script-based operation.

Is there a free trial available?

Yes. A 14-day full-featured free trial is available for download at [t-ia-connect.com](https://t-ia-connect.com/).
