The OPC UA Online Reference is a searchable collection of specifications and information models.
Information models are made available by publishing a index of types defined in the model as human readble tables. When possible the definition of a Type is linked to the appropriate section in the specification. These tables are generated automatically from the published NodeSet.
A subset of specifications are also made available. These pages are automatically generated from Microsoft Word documents. The documents are generated from the latest released version with errata applied. Note that the online reference is a work in progress and not all published errata will be in the online documents.
Every effort has been made to ensure the online versions of the specifications match the documents available on the OPC Foundation website. If any differences exist between the documents and published errata and the online version then the documents and published errata should be assumed to be the correct version.
