Everything written on this site is open and always will be: status codes, glossary, spec guides, code recipes, lesson transcripts. An account unlocks the video, the labs, the downloadable code bundles and the exams. No card, no trial, no sales call.
Open to everyone
Every reference page. Every lesson's written body and transcript. Every code recipe. No account, no wall, no email required, and that is deliberate: gating the text would make this site useless to the person who needs it at 2am.
Behind the free account
Lesson video, hands-on labs against the public OPC UA servers, downloadable code bundles and nodeset files, progress tracking across courses, and the credential exams.

You are in
Your access is unlocked on this browser, across every course. We have also emailed you the three OPC UA references (the Status Code Diagnostic Tree, the Server Acceptance Test Pack and the Machine Data to OEE Mapping Kit) so you keep them even if you switch device.
That did not go through. Email contact@teeptrak.com and we will set your account up by hand.
What happens to your details
Plainly, because this is an engineering audience and vagueness here is irritating. This is a contact form, and it reaches a human. When you submit it, your details go to our team and a record is created in our CRM. Someone from TEEPTRAK may get in touch about industrial data collection. If you would rather nobody did, do not fill this in: every written page on this site is open without an account, and always will be.
Your access does not depend on any of that. It unlocks immediately in this browser, whether or not anyone contacts you, and whether or not you reply if they do.
We do not sell your details or pass them to anyone outside TEEPTRAK. Email contact@teeptrak.com and we will delete your record and your account.
