DataHub MQTT Smart Broker with Sparkplug B for Robust Industrial Applications

Standard MQTT Broker Support 

DataHub's real strength lies in it's native, automatic conversion to OPC data protocol standards, ability to expose any data you can get into DataHub via the broker, and its other "Smart" capabilities including it's Sparkplug B support.  If you try to use a "free" broker with your OPC servers, you have to define, manage and support those connections and not all information is passed as reliably as the DataHub.

The DataHub MQTT Broker in it's basic configuration, operates as a standard MQTT broker with these features and adds Smart Broker features and overcomes MQTT weaknesses at no added cost as shown on this page. 

• SSL/TLS or Plain Text Communications
• Encoding via
  • UTF-8
  • Base-64
  • JSON
• User/password support
• Multiple JSON formats per connection 
• Scalable - large # of MQTT client connections possible.

What's a Smart MQTT Broker?

The power of DataHub emerges when you leverage it's smart abilities to deal with some of the limitations of MQTT, specifically in it's ability to 

• Bidirectionally convert protocols - MQTT to OPC DA, OPC UA, OPC A&E and back to MQTT
• Convert MQTT SparkplugB to standard MQTT for systems that don't support SparkplugB
• Supports IETF draft specification for JSON Schemas 
• Automatically extract data into an array of 
  • Name
  • Value
  • Quality
  • Timestamp
• Connect points to topics
• Manage and propagate "Not connected" Quality so that MQTT clients know how to interpret the data received

This power is further extended with the Sparkplug B support and ability to add security not found in MQTT including Sparkplug B.
