What OPC UA NodeIDs Are
NodeIDs are the identifiers that let a client refer to objects, variables, and other nodes inside an OPC UA server. A routable endpoint is not enough on its own; stable NodeID selection is what turns browsing into a usable mapping workflow.
Why It Matters
- Point lists often need exported NodeIDs rather than screenshots.
- Rebuilt server models can break assumed node paths.
- Read-only gateway workflows still depend on dependable NodeID intake.
