Warning
Changes made at an edge device to UDT definition member tags are not propagated through the system. You will see that any tag instances of that UDT at the edge device will reflect the changes, but the recorded definition for the UDT at engine will not change nor will tag instances for other edge devices using that definition.

UDT collision detection uses the MD5 sum of the UDT to detect differences.

If a collision is detected, a warning will be logged and you can see the detail by setting the com.cirruslink.mqtt.engine.gateway.sparkplug.SparkplugBPayloadHandler to TRACE.

This detail will show the UDT definition at MQTT Engine and also the UDT definition published in the NBIRTH message. The offending edge node can be identified from the NBIRTH message.
