How it is assessed

All three credentials above, plus a timed troubleshooting practical: four broken configurations, and for each you must name the status code, the root cause and the fix. Small cohort; holders are listed publicly with their consent.

What it is aligned to

Aligned across the client and server facets covered by the other three credentials, plus the Part 7 profile and facet machinery and the conformance-unit mapping published in the released nodeset documentation files.

What this credential is not: This credential is issued by OPC UA Connect and by nobody else. Certification in the OPC UA ecosystem is a product-level programme: a specific product version is tested at an independent laboratory against named profiles and facets. We are not aware of any individual, person-level OPC UA certification offered by the specification's publisher or by any standards body. So this certificate is not issued by, recognised by, endorsed by, accredited by or equivalent to any such programme, and it should not be described as one. What it does assess is real, and the profiles and facets it is aligned to are public and named: see our disclosure page for how we state all of this.

The exam needs a free account.
