Matrikon® Data Broker MQTT Publisher [Extension]

Version 2.2

Use MQTT Publisher to enable MDB to securely publish its data over the popular Message Que Telemetry Transport (MQTT) to the cloud provider of your choice. MQTT Publisher is a dedicated Matrikon Data Broker (MDB) extension that makes it easy to securely send OPC UA formatted data to the following cloud providers: Microsoft Azure, AWS, and Google Cloud.

Cost-Effective Publishing

MQTT Publisher Data Queuing and Data Compression functionality minimize data publishing costs by improving the data-to-overhead ratio and reducing the raw volume of data that needs to be sent to convey the same information.

Note: if your shopfloor data sources are behind a firewall or DMZ, refer to the MDB webpage to learn how you can easily overcome these common challenges.

Use Cases
  • Data is often published over MQTT in one-to-many scenarios where an MQTT publisher makes data available to MQTT subscribers. The connectionless aspect of MQTT makes it a popular choice for WAN (internet) based applications because it avoids the types of security threats associated with point-to-point connection-based transports.
  • MQTT Publisher uses OPC UA PubSub compliant JSON data encoding to maximize interoperability. This minimizes future sustainability challenges associated with supporting custom JSON encoding
