Durable subscriptions are OPC UA subscriptions with a very long lifetime and large queues so that monitored data can be collected and stored during times where the Client is disconnected. When the disconnected Client connects and creates a Session it will transfer the Subscription to this Session and receive the queued data and events.

Description Durable subscriptions are OPC UA subscriptions with a very long lifetime and large queues so that monitored data can be collected and stored during times where the Client is disconnected. When the disconnected Client connects and creates a Session it will transfer the Subscription to this Session and receive the queued data and events.

Usage Considerations

  • "Disconnected Client" - i.e. Client can connect only once or a few times a day
  • Stored data and events are available even after server restart

Conformance Testing

Client Server

Create and manage durable subscriptions

Durable storage of data and events while Client is disconnected
