TIA MCP工具

TiaCommander — MCP Server for Siemens TIA Portal

*\V15.1–V18 and V20–V21 are expected to work as TIA Portal maintains backward-compatible Openness APIs across versions, but have not been tested. Only V19 is fully tested.

---

Overview

TiaCommander is an MCP server that connects AI assistants to Siemens TIA Portal via the Openness API. It enables AI-assisted PLC programming, project management, library operations, hardware configuration, cross-reference analysis, and deployment — all through natural language.

Tested AI clients: Claude Desktop, Claude Code, VS Code (Copilot), Cursor, Windsurf, Codex CLI, Gemini CLI.

16 tools, 166 actions covering the full TIA Portal project lifecycle.

No installer, no registry changes, no system modifications. Extract, configure, and run. Download the latest .zip from GitHub Releases.

Claude Desktop users: Download the .mcpb bundle from Releases and install via Settings → Extensions → Advanced Settings → Install Extension. No config file editing needed. See the Quick Start Guide for details.

Prerequisite: Siemens TIA Portal V15.1 or later must be installed on your machine. TiaCommander loads Siemens Openness libraries directly from your TIA Portal installation at runtime — it will not start without TIA Portal.

What's Next

TiaCommander is actively developed. Here's what we're working on:

• HMI integration — Openness API access to HMI screens, tags, and alarm views
• Runtime monitoring — live PLC data via Web API and OPC UA (S7-1200 V4.4+, S7-1500)
• TIA Portal V20 support — updated Openness DLLs and new API features
• PLCSIM Advanced — simulation control for offline development and testing
• S7-1500 expanded testing — broader device family coverage with telemetry-driven validation
