Your AI Assistant for
TIA Portal Automation
Stop switching between your AI chat and TIA Portal. T-IA Connect gives any AI model direct access to your PLC project — read code, create blocks, manage tags, compile and deploy — all from a single natural language command.
What Is a TIA Portal AI Assistant?
A TIA Portal AI assistant is an AI model — Claude, ChatGPT, Copilot, or a local LLM — that can directly read and modify your TIA Portal project. Not just answer questions, but actually perform engineering tasks: creating function blocks, generating SCL code, managing PLC tags, running compilation, and downloading to hardware.
T-IA Connect acts as the bridge. It exposes 60+ TIA Portal operations through the Model Context Protocol (MCP), so your AI assistant can work inside your PLC project the same way a human engineer would — with full context of your existing code structure.
What the AI Assistant Can Do
Real TIA Portal actions, executed by your AI in seconds
Read Project Structure
The AI reads your entire TIA Portal project — devices, programs, function blocks, tags, and data blocks — before writing a single line of code.
Generate SCL Code
Describe what you need and the AI writes complete, production-ready SCL function blocks with proper error handling, comments, and interface definitions.
Manage PLC Tags
Create, update, or bulk-import tags from IO lists. The AI handles naming conventions, data types, and memory addresses automatically.
Create Data Blocks
From simple DB structures to complex UDTs — the AI creates data blocks that match your project's naming and organization standards.
Compile and Download
Run full compilation, check for errors, and download to real or simulated PLC hardware — all triggered through natural language commands.
Document Existing Code
Point the AI at undocumented legacy blocks. It reads the logic, understands the intent, and writes comprehensive block comments and documentation.
How It Works
From install to first AI-generated code in minutes
1. Install T-IA Connect
Download and install on your engineering workstation. It runs locally as an MCP server alongside TIA Portal — no cloud, no VPN, no data leaves your network.
2. Connect Your AI Client
Configure your AI client (Claude Desktop, Cursor, VS Code, or any MCP-compatible tool) to connect to T-IA Connect. Takes less than 5 minutes.
3. Open TIA Portal and Start
With TIA Portal open, your AI assistant can read your project and start performing tasks. Ask in plain language — the AI handles all TIA Portal API calls.
Works with Any AI Model
Not locked to one vendor — use the AI that fits your workflow
Claude (Anthropic)
Best choice for complex SCL generation and code refactoring. Excellent at understanding safety-critical PLC logic and multi-step automation workflows.
ChatGPT / GPT-4o
Strong for tag management, documentation, and code conversion tasks. Works through Cursor, VS Code, or any OpenAI-compatible client.
Local Models (Ollama)
Full air-gap support. Run Llama 3.1, Qwen 2.5 Coder, or Mistral locally. Zero cloud dependency, complete data sovereignty.

Read moreFrequently Asked Questions
Does the AI assistant work offline?
T-IA Connect runs 100% locally on your workstation. The MCP server and TIA Portal integration work offline. The AI model itself can be local (Ollama) for full air-gap operation, or cloud-based (Claude, ChatGPT) — your choice.
Which TIA Portal versions are supported?
T-IA Connect supports TIA Portal V16, V17, V18, V19, V20, and V21. It uses the TIA Openness API, which is available from V16 onwards.
Is my PLC code safe? Does it get sent to the cloud?
Your TIA Portal project data stays on your machine. T-IA Connect runs as a local server — it never sends your code anywhere. If you use a cloud AI model, only the specific context needed for each task is sent, and only when you initiate a command.
Can I use T-IA Connect without a paid AI subscription?
Yes. T-IA Connect works with any MCP-compatible AI client. You can use free tiers of Claude or ChatGPT, or run a fully local model with Ollama at zero cost.
