Spark plug transfer object

Sparkplug transfer objects send data via a Sparkplug connection; the connection profile determines which of the two is used.

  • Sparkplug Node Publish – sends a payload to applications using Group, Node, and Device IDs; can only be used with connections in the Node profile.
  • Sparkplug Application Command – sends arbitrary commands to Sparkplug nodes via Group, Node, and Device IDs; can only be used with connections in the Application profile.
