Stuck? Ask a practising engineer

A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.

  • Questions answered in the context of the module you are on
  • The same engineers who teach the AEP programme
  • Career tools, CV help and public job listings included
  • Your progress and notes stay in your account for good

Common questions

Is TwinCAT free to learn on?

Yes. TwinCAT 3 XAE downloads free and runs on a 7-day trial licence you renew by typing a captcha. No hardware needed.

Do I need Visual Studio?

No. TwinCAT installs its own XAE shell; a full Visual Studio is optional.

Why so much structured text?

Because TwinCAT projects in industry are mostly ST with object-oriented features. Ladder, CFC, SFC and FBD are covered too.

Is this CODESYS?

TwinCAT 3 shares the CODESYS editor heritage, so the CODESYS course on this site is a good preparation; TwinCAT adds Beckhoff's runtime, EtherCAT, ADS and tooling.

Is the course really free?

Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.

What certificate do I get, and is it a Beckhoff qualification?

An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a Beckhoff credential and is never described as one.
