EDWartens Lab
Practise this in the EDWartens Lab
Write and test the same ladder logic in the Lab's PLC simulator, go online and force inputs. The Lab uses a vendor-neutral editor, so brand software stays in the course.
Works alongside Mitsubishi GX Works3: MELSEC iQ-R and iQ-F. The Lab is plc programming practice in your browser: no install, no hardware, free to use. Sign in as a learner and it opens with your account.

Why practise in a lab
Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.
- Practise safely, so a mistake costs nothing.
- The lab checks your work like a site test, so you know when it is right.
- Free, in your browser, with nothing to install.
