LADX Mini is the light version of LADX Studio, built into your student portal. Use it to practise PLC ladder logic while you learn.
- Open LADX Mini in the portal menu, just under Dashboard.
- Start a blank project with the + button, or open one of the Worked examples.
- Draw your ladder logic, then press Simulate and watch power flow through the rungs the way it would on a live controller. Stop and Reset clear it again.
Your projects save to your account as you work, so you can carry on from any device. You can delete a project you no longer want.
It runs in your browser, so there is nothing to install and no hardware to buy. For the full AI-based PLC programming experience, the page points you on to LADX.AI.
LADX Mini is a practice tool. It does not replace the vendor software your course uses.
