概览
A desktop app that lets you read and edit your TIA Portal V20 project through a built-in browser window — no extra software or cloud connection needed. It connects to TIA Portal while it's running on your PC and opens a native Windows window at startup. Anyone working with Siemens S7 PLCs who wants a faster way to browse blocks, view/edit SCL code, inspect tag tables, and manage their project — without clicking through TIA Portal menus. It also exposes all tools to Claude AI via MCP so you can describe changes in plain English and have Claude implement them. See What is TIA Portal Openness? for a plain-English explanation of the API this project is built on. See the User Manual for a full walkthrough of both operating modes. Both modes talk to the same REST server and the same TIA Portal connection.

TIA Portal Dashboard
A desktop app that lets you read and edit your TIA Portal V20 project through a built-in browser window — no extra software or cloud connection needed. It connects to TIA Portal while it’s running on your PC and opens a native Windows window at startup.
Who is this for? Anyone working with Siemens S7 PLCs who wants a faster way to browse blocks, view/edit SCL code, inspect tag tables, and manage their project — without clicking through TIA Portal menus. It also exposes all tools to Claude AI via MCP so you can describe changes in plain English and have Claude implement them.

Ready to use? See the User Manual for a full walkthrough of both operating modes.
Two modes
| Mode | Tab | How to use it |
|---|---|---|
| User Control | Left tab | Fill in fields and click Run — fully manual, no AI |
| Agent Control | Right tab | Claude calls tools automatically via MCP — describe what you want in plain English |
Both modes talk to the same REST server and the same TIA Portal connection.
What it can do
| Feature | Description |
|---|---|
| Browse blocks | See all OBs, FBs, FCs, and DBs in the sidebar |
| Read & edit SCL code | View and save SCL source directly in the window |
| Raw XML editor | View and import block XML for any language (LAD, FBD, STL, GRAPH) |
| Compile blocks | Trigger compilation and see the result inline |
| Analyse SCL | Scan SCL code for issues (unbalanced blocks, nested IFs, etc.) |
| Create blocks | Generate new FB, FC, OB, or GlobalDB from SCL source |
| Create LAD blocks | Build an FB, FC or OB from a structured rung description (contacts, coils, set/reset, compares, edge detection, timers, counters, Sr/Rs, arithmetic, scaling, parallel branches, move, FB/FC calls, system functions); imported and compiled for you, compiler output returned. Verified on TIA V20 / S7-1200 |
| Create instance DBs | Create a new Instance DB linked to any FB |
| Patch block texts | Update a block’s title, comment, and per-network titles without touching logic |
| Block attribute inspector | List all readable/writable attributes and compositions on any block |
| Browse tag tables | See every tag, its data type, address, and comment |
| Import tag tables | Import a complete tag table from SimaticML XML |
| Batch rename tags | Rename many tags at once in a single atomic operation |
| Create tags | Create a tag table, or add individual tags with type, address, and comment |
| Export blocks & tags | Export any block or tag table to SimaticML XML on disk |
| I/O mapping | List a device’s I/O points — module, channel, address, direction |
