DataHub IoT Gateway

IoT-Gateway Diagram

The DataHub™ IoT Gateway™ streams real-time OPC UA and OPC DA industrial data directly into Manufacturing Execution Systems (MES), device clouds, and Big Data analytics platforms.

You can

  • Connect OPC UA and OPC DA (Classic) clients and servers to any MQTT Broker, including Azure, Google and Amazon IoT.
  • Publish and subscribe.
  • Customize JSON data formats to connect almost any MQTT application.
  • Implement Transport Layer Security (TLS), certificate-based authentication, username/password authentication, Last Will and Testament, and Quality of Service message delivery.
  • Use MQTT Version 3.1.1, including publish and subscription methods.
  • Connect directly to AWS IoT with a self-signed certificate, without relying on a third-party intermediary.

Unique Advantages

  • No point count restrictions.
  • Includes both client and server interface for both UA and DA.
  • Maintains the OPC UA data model, while other gateways flatten it.
  • Automatic OPC ↔ MQTT protocol conversion built-in.
  • Automatically discovers all the points from the server.
  • Eliminates cache latency and stale data, so you always know the data quality and have the most current value.
  • Multi-threaded interface means that a slow or non-responsive server will not slow down other connections.

One key advantage of using the DataHub IoT Gateway is that the data model stays intact, unlike other gateway solutions.  The full data hierarchy from the OPC UA server gets faithfully represented in the OPC DA client or MQTT broker.
