The first message shows the 'NBIRTH' message which is an indication that the Sparkplug Edge Node has come online. The second message is a Sparkplug DBIRTH message denoting that a Sparkplug Device has come online along with its 'metrics' or tags, their metadata, and values. In this case we only had a single tag so that is all that is included in the payload.

Because Azure Injector is driven by tag change events, try writing a '10' to the T1 tag. This should result in a new DDATA message as shown below.
