  • Tag Provider Name
    • The name of the Tag provider containing the tags.
  • Tag Path
    • An optional folder path under the Tag provider where the root folder of the Tags can be found.
  • Push Trigger
    • Defines what triggers a push to the cloud endpoint
      • EVENT_DRIVEN (default) - when a tag change event occurs, and no pending push exists, tag events will be aggregated for the 'Tag Pacing Period' before being pushed
      • PERIODIC - will push data for all tags associated with the Agent every 'Tag Pacing Period'
  • Tag Pacing Period
    • The buffer period, in milliseconds, that Tag events will be aggregated into a single payload before pushing.
  • Convert UDTs
    • Whether to convert UDT members to normal Tags before publishing.  If enabled the Tags representing the UDT member will retain their member path prefixed by the UDT Instance name.
  • Publish UDT Definitions
    • This can only be set if 'Convert UDTs' is false
    • Whether or not to publish include UDT definitions in the NBIRTH message
  • Optimize UDTs
    • Whether or not to 'convert UDTs' only for DATA messages.
  • Set
    • The Set of Azure IoT Hub endpoints that the Tag Agent will push to.
  • Auto-discover Tags
    • Whether newly added tags should be dynamically scanned and their values pushed.  This field is disabled by default.  It should remain disabled while manually editing tags and/or their configurations. It should only typically be enabled in systems where tags are created in real time.

...

As you can see, the Sparkplug settings can be used to either hard-code these IDs, or leave them blank so that the Agent will scan and discover them based on the tag tree layout.  For more information see this document keeping in mind that MQTT Transmission Transmitters can be thought of like 'Agents' in Injectors with regard to Sparkplug IDs and tag trees.

Advanced

  • Filtered Properties
    • A semicolon delimited list of Tag properties to filter/block from being published.  These should typically not be modified unless there is an explicit requirement that a specific property is needed to be added or removed from the default.
