LADS — Laboratory and Analytical Device Standard
Laboratory and Analytical Device Standard — lab automation, sample handling, analytical instrument workflows. Pulls AMB, Machinery, and DI.
OPC UA companion specification for laboratory automation — sample-handling robots, plate readers, spectrophotometers, analytical instruments. Distinct from ADI (which focuses on process-analytical devices); LADS targets discrete lab workflows.

- AMB — for asset / maintenance records
- Machinery — for the machinery-item base type
- DI — comes via the cascade
Notable types
The two DTOs cover lab-specific records — sample identification, result aggregation. Workflow-specific shapes; see the NodeSet2.xml source for the field layouts.
Notable enums
DeviceState_LADSEnum— instrument operational state with lab-specific values (e.g. "ReadyToRun", "Aborting").
