Licence and FAQ

Demo and full version

The demo is the whole app: every part, the physics, the PLC connection and the AI assistant. Plants of basic parts (belts, rollers, sensors, buttons, the E-stop) run and save without limits. A plant with a full-version part, such as a turntable, a palletizer or a stacker crane, runs for 10 minutes of simulated time per run and is not saved.

The full version is a yearly licence; see Pricing. To enter your key, click the Demo badge in the app bar and Activate.

FAQ

Windows or macOS warns me when I start the app. The app is not code-signed yet. Windows: More info → Run anyway. macOS: right-click → Open → Open, or System Settings → Privacy & Security → Open Anyway.

Do I need a PLC? No. In Run mode the Signals card switches every output by hand, and the samples have a demo program.

Which PLCs work? S7-1500, S7-1200 and S7-PLCSIM Advanced over PUT/GET. The plain S7-PLCSIM is not supported. See Connect your PLC.

Where are my projects? Project ▸ Show project folder opens it. A project is a folder you can zip, share or keep in git.

What does the AI assistant need? An API key from your Anthropic account, entered once in the assistant. The key stays on this computer and is never saved in a project. Chats are kept on this computer (up to 50, 30 days); Preferences › Assistant conversations turns this off or deletes them.

Does the assistant write my PLC program? No. It builds and changes the plant and explains the signals; the program is yours.

The loads jam or fall off. That is the physics: loads move only by friction, so they slip, queue and tip like real ones. Leave gaps before curves, use side guides, and keep inclines moderate.
