Common questions

Is PLCWare - TIA Portal (tia) safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 5 days ago, and the latest version (1.12.3) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

PLCWare — for Siemens TIA Portal V21

Try it free for 30 days. The trial is self-serve, includes the Pro scopes and needs no card:

[Start the 30-day trial](https://plcware.io/en/trial?utm_source=github&utm_medium=readme&utm_campaign=hub)

· plcware.io has the plans and prices.

PLCWare automates Siemens TIA Portal V21 through its native Openness interface, exposed as a local HTTP/JSON API on the engineering machine. Create devices and networks, generate and import SCL/SimaticML, manage blocks/types/tags, and run compile → download → online — all behind a clean HTTP surface that any application, script, or AI assistant can drive.

It carries every bit of complexity the Openness API forces (net48/AMD64 assemblies, runtime assembly resolution, a single serial worker that owns the TiaPortal) and hides it behind HTTP, with a system-tray GUI (start/stop/monitor the API) and a CLI for headless use.

This is the product hub — downloads, documentation, and customer support. The

application is proprietary; its source lives in a separate private repository.

How it fits together

Three pieces, split by what runs where:

Piece	What it is	License	Where
PLCWare app / `serve`	The engine — a Windows app that drives TIA Portal V21 and exposes the HTTP/JSON API. This product.	Proprietary (activation license)	Releases
`@renanlido/tia-openness-mcp`	The bridge — a thin MCP→HTTP client so AI tools (Claude, Codex, Gemini, Cursor…) can drive the API.	MIT (open)	npm
`tia-harness`	The client harness — a Claude Code plugin (skills + subagents) that turns an engineering spec into a verified TIA project.	MIT (open)	renanlido/tia-harness

The MCP and the harness are open and free. The serve app is what actually talks to TIA Portal, and it's the licensed product.

Download

Free to download. Grab the latest installer from the Releases page:

TIAOpenness-Setup- .exe — one-click installer (recommended): copies the app and runs first-time setup (adds you to the Siemens TIA Openness group, creates a shortcut, optional autostart), then opens the Getting started screen.
TIAOpenness-app- .zip — portable build; unzip and run TIAOpenness.exe setup.

Prerequisites: Windows 10/11 (x64), .NET Framework 4.8 (the installer checks), and TIA Portal V21 + the Openness component installed (the app loads the Siemens assemblies from your local install — they are not redistributed).

See the [Getting started guide](docs/getting-started.md) for the full walkthrough.

Languages

The app ships bilingual — English / Portuguese:

The desktop app (GUI, CLI, setup and diagnostics) auto-detects your Windows language (English everywhere outside Brazil). You can also pick explicitly: in the installer wizard, in the app's Language selector, or with --lang en|pt on the command line.
The docs and the `tia` MCP server (tool descriptions, remediation hints, messages) are English.
The HTTP API speaks English; a few human-readable status texts (environment checks, license status) follow the app's configured language.

Try it — free download, license to use

The app follows the "download free, activate with a license" model (like JetBrains / Sublime):

The download is public and free — anyone can install it.
A valid activation license unlocks use. Without one, every API endpoint except GET /health answers 403 license_required, so the binary does nothing until activated.
The activation license is a cryptographically signed token, validated offline — no phone-home required to run.

Want to evaluate it? Start the self-serve 30-day trial at plcware.io/en/trial: it includes the Pro scopes and needs no card.

Plans and licensing

Plans and prices are on plcware.io. Licensing covers per-seat use, with tiers from inspection/scaffolding up to full create → compile → deploy and hardware control. For licensing questions, contact PLCWare support or email support@plcware.io.

Drive it from AI (MCP)

The app is non-opinionated (endpoints pass parameters straight through to Openness), which makes it ideal to drive from an AI assistant. The `tia` MCP server is a thin HTTP client published on npm. The PLCWare 1.7.1 Windows installer bundles the MCP runtime for app-managed connections to Claude Code, Claude Desktop and Codex, including desktop-only Codex. These routes need no system Node.js/npm or Git. Desktop's .mcpb/settings fallback, the separate Desktop skills step and Codex plugin setup are documented in [docs/INSTALL.md](docs/INSTALL.md). The public Codex CLI plugin, Gemini CLI extension, manual setup, older versions and Mac/Linux/remote clients without the Windows installer payload retain the npm/npx route. The commands below are manual MCP-only alternatives, not additions to an existing plugin connection.

npx -y @renanlido/tia-openness-mcp

For Claude Code (one line, user scope):

claude mcp add --transport stdio --env TIA_API_BASE=http://localhost:5000 --scope user tia -- npx -y @renanlido/tia-openness-mcp

Other clients (Claude Desktop, Codex, Gemini CLI, Cursor, VS Code, Windsurf) and the Windows cmd /c npx gotcha are covered in [docs/INSTALL.md](docs/INSTALL.md).

The MCP never sends a key — activation is the host's responsibility (the license configured

on the serve machine). Without a licensed serve to point at, the MCP can only diagnose

connectivity (tia_ping).

MCP client: MIT (see LICENSE). Desktop app: EULA.

For an end-to-end harness that turns a structured spec into a verified TIA project, install the tia-harness Claude Code plugin.

MCP Registry releases

The publish-mcp-registry workflow publishes io.github.renanlido/tia-openness when this hub publishes an mcp-vX.Y.Z release. The release must already contain server.json; its server and package versions must match both the release tag and the exact version available on npm. The workflow verifies the pinned publisher's Sigstore bundle before authenticating through GitHub OIDC. No Registry token or new secret is required.

The application releases (app-v*) are ignored. For a failed MCP publication, correct the release asset if necessary and rerun the failed workflow from Actions. Local validation: node --test .github/scripts/verify-registry-manifest.test.mjs.
