Connects OPC UA and OPC DA (Classic) clients and servers to any MQTT Broker, including Azure, Google and Amazon IoT
Supports publish and subscribe
Offers customizable JSON data format to support most MQTT applications
Supports Transport Layer Security (TLS), certificate-based authentication, username/password authentication, Last Will and Testament, and Quality of Service message delivery
Supports MQTT Version 3.1.1, including publish and subscription methods
Supports self-signed certificates from AWS IoT, enabling direct connection without a third-party intermediary
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
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.
Other add-on features for the DataHub OPC Gateway include DDE/Excel support for connecting to Excel spreadsheets and other DDE servers, Email/SMS notification to receive an email or SMS message based on data changes, data historian to store and retrieve large volumes of data at high speeds, data redundancy to do hot standby switching between identical data sources, and camera to stream live video or images of your system.
