Writer

This section contains the API to configure data set writers and writer groups inside OPC Publisher. It supersedes the configuration API. Applications should use one or the other, but not both at the same time.

        The method name for all transports other than HTTP (which uses the shown
        HTTP methods and resource uris) is the name of the subsection header.
        To use the version specific method append "_V1" or "_V2" to the method
        name.

ExpandAndCreateOrUpdateDataSetWriterEntries

POST /v2/writer

CreateOrUpdateDataSetWriterEntry

PUT /v2/writer
Description

Create a published nodes entry for a specific writer group and dataset writer. The entry must specify a unique writer group and dataset writer id. A null value is treated as empty string.
