OPC UA NodeId Syntax & Namespace Verifier
Validates OPC UA NodeId formats across numeric, string, GUID, and opaque types.
Notice: engineering verification utility. Use test or de-identified data and verify results independently before relying on them.
How it works
Standard: OPC UA Part 6: Address Space Model
Formula: ns=index;i=number OR ns=index;s=string OR ns=index;g=guid OR ns=index;b=base64
Checks: Namespace index non-negative; identifier format matches identifier type specifier
