Errata exists for this version of the document.
Table 67 defines values for the statusCode parameter and Table 68 defines values for the inputArgumentResults parameter that are specific to this Service. Common StatusCodes are defined in Table 178.
Server vendors or OPC UA companion specifications may reuse existing StatusCodes for application specific error information. This is valid as long as the canonical description of the StatusCode does not have a different meaning than the application specific description. To eliminate any vagueness, the Server should include the application specific description in the DiagnosticInfo.
Good StatusCodes with sub-status shall not be used as statusCode since many programming language bindings would cause such codes to throw an exception.
