A UNS Transmitter is an agent that monitors tags and publishes them as MQTT Messages with a JSON payload to an MQTT Server. 

The UNS Transmitter can be configured to read tags from the UNS structure created by MQTT Engine and publish tag changes over MQTT to any Enterprise consuming clients.

• Messages can be consumed by any MQTT client that can parse JSON messages.
• Any MQTT client created by the agent will only publish data using the MQTT protocol.
  • Uses the namespace unsAv1.0 which can be disabled
  • A single data message is published for each tag when QualifiedValue of the tag changes 
  • A single properties message is published for each tag on every client connection
• Has no concept of Ignition UDTs
