MQTT Publisher for OPC UA

MQTT Publisher allows Matrikon Data Broker (MDB) to securely publish data over the Message Queuing Telemetry Transport (MQTT) to your chosen cloud provider, including Microsoft Azure, AWS, and Google Cloud. This extension of MDB simplifies sending OPC UA formatted data securely to the cloud.

Cost-Effective Publishing
MQTT Publisher’s data queuing and compression features reduce publishing costs by improving the data to overhead ratio and decreasing the volume of data that needs to be transmitted.

Use Cases

MQTT is often used in one-to-many scenarios where an MQTT publisher provides data to multiple MQTT subscribers. Its connectionless nature makes it ideal for WAN (internet) applications, reducing security risks associated with point-to-point connections.

MQTT Publisher uses OPC UA PubSub compliant JSON encoding to maximize interoperability and minimize future sustainability issues related to custom JSON formats.
