OPC UA supports arbitrarily complex data structures that can be read or written as a single value. The information how to decode structures is provided in the Address Space so that they can be explored and used on the fly.
Servers can provide elements of a structure as separate Variables with potentially simple data types.

Usage Considerations
Efficient and consistent transfer of data that belong together.

Conformance Testing

Client Server
  • Determine the type and encoding of structures.
  • Read and decode or encode and write arbitrary structures.

Expose Variables with structured types, provide the encoding, provide read/write access
