OPC Reactive Extensions (Rx/OPC) are OPC-specific classes that implement the Rx interfaces. With Rx/OPC, you can e.g.:

• Create observable collections (data streams) that provide OPC events.
• Consume (observe) data streams, and process them using OPC.
• Combine data flows to create more complex operations.

For OPC Alarms & Events, Rx/OPC gives you the ability to work with flows representing OPC event notifications, or flows that represent OPC event conditions to be acknowledged.
