OPC UA includes several features that ensure the robustness of OPC UA communication and that are integrated in different layers of the OPC UA Framework. It includes

  • Error detection and handling on transport and service level,
  • Buffering of data so that they are not lost during a network connection
  • Auditing – i.e., the support for security audit trails with traceability between Client and Server audit logs., and
  • Availability of diagnostic information.

Note – The Robustness features are specified as part of the Services in OPC UA Part 4.
