I'm new to OPCUA protocol, and I want to make OPCUA server on device that samples continious analog signal. What is the best OPCUA arhitecture for fast continious sample transfer to client?

I recommend

OPC UA Pub/Sub architecture : OPC 10000-14: OPC Unified Architecture

Meaning OPC UA over MQTT.

Reason:

  1. From a data speed perspective
  2. END-TO-END encryption
  3. OPC UA object encoding
  4. standards-based data connectivity
