Configuring UNS Transmitter Payload

Ignition Modules
1

Hello,

We have started publishing Ignition tags to an MQTT broker via the UNS Transmitter. Currently, the transmitter publishes additional metadata (qualityCode, dataType, name, etc.) alongside the tag value.

We are exposing process parameters to downstream applications and want to publish either the value or a simpler payload. Some of the metadata is redundant (name and dataType) while qualityCode requires the consumer to understand the meaning of Ignition quality codes in order to interpret it.

Example:

Topic:

someTopic/folder1/speed

Current Payload:

{
  "name": "someTopic/folder1/speed",
  "dataType": "Float",
  "value": 25,
  "timestamp": 1780339660850,
  "qualityCode": 192
}

We would like to publish either:

25

or

{
  "value": 25,
  "timestamp": 1780339660850
}

Is there a configuration option to customize or simplify the payload produced by the UNS Transmitter?

Thanks!

At this point it is not possible to customize the UNS Transmitter payloads.
