ABOUT PROEKSPERT

20+ years of expertise delivering measurable results

With 20+ years of experience in industrial test automation, Proekspert has partnered with global leaders like Danfoss to deliver scalable, reliable solutions as part of our industrial software engineering services.

Using frameworks built on LabVIEW and TestStand, we ensure precision and efficiency while reducing regression testing time and enabling seamless scalability across product variants.

Technologies
LabVIEW, NI TestStand, custom database, SQL, legacy code stabilization, operator UI improvements.

Client challenge/business need
This manufacturer needed to upgrade factory test automation built on legacy hardware and custom LabVIEW systems – ensuring reliable end-of-line testing, reduced downtime, and scalable production growth.

Solution at a glance
Proekspert mapped, modernized, and migrated core automated tests to NI TestStand, reusing LabVIEW assets and overhauling databases for transparency and direct access. The team delivered UI upgrades for operator efficiency and stabilized integration – enabling step-by-step migration with no production disruption.

Results

Lower risk of failure. Critical tests now run on a supported, stable automation platform – no more legacy hardware headaches or hidden bugs.
Higher operator productivity. A streamlined, more intuitive UI and transparent data access speed up daily work and troubleshooting, with less retraining.
Ready to scale. The test platform can now support new products and sites quickly – without carrying old technical debt forward

Client challenge/business need
Danfoss runs large scale automated testing across development and production for its frequency drive portfolio. Quality assurance is a permanent, mission critical function that must remain reliable as products, firmware, and global sites evolve. The challenge is sustaining and evolving this test infrastructure without disrupting releases or operations.

Solution at a glance
Since 2008, Proekspert has operated and continuously evolved Danfoss’s automated QA environment. We modernize and maintain NI TestStand based workflows, reuse and stabilize LabVIEW assets, improve databases for transparency, and refine operator UIs – ensuring the test platform evolves safely alongside products without interrupting production.

Results

Lower operational risk. Critical drive tests run on a stable, supported automation platform that is continuously maintained, improving test reliability and confidence across releases.
Sustained operator productivity. Clear operator UIs and transparent access to test data support efficient daily work, faster troubleshooting, and consistent execution across global test environments.
Built to scale long term. A mature automated test platform supports new drive models, firmware generations, and production sites without introducing legacy constraints or maintenance risk.
