At this point, modify the URL to point to the Ignition Distributor gateway.  Example: If your Gateway IP is 10.1.10.97 then set the URL to tcp://10.1.10.97:1883 and save your settings.(Below   Confirm your connectivity from Edge to Gateway (below are two possible examples):

When done with the steps above, you should have a folder/tag structure as shown below.

Note additional tags could be added to the 'Device 1' folder as well.  These could be OPC tags, UDTs, or other types of tags.  Also, additional folders could be added below this level as well.  The structure of the 'default transmitter' requires that the first three folder levels represent the Sparkplug Group ID, Edge Node ID, and Device ID respectively.

At this point, we can start the Transmitter by writing to the 'Transmission Control/Refresh' boolean tag.  Writing to this tag tells MQTT Transmission to rescan the entire tag tree, detect the folders and tags present, and then begin publishing Sparkplug messages to the MQTT Server.  The location of the tag to write to is shown below.

Step 8: Verify MQTT Transmission is Connected

Open the Ignition Edge MQTT Web UI and browse to 'Configure → MQTT Transmission → Settings → Servers' and verify the connected status shows '1 of 1'.  If it does not, double check the firewall and antivirus settings on the Central Ignition Gateway and ensure port 1883 is open.

Step 9: Verify Data Flowing into MQTT Engine

With MQTT Transmission now connected, open Ignition Designer on the Central Ignition Gateway.  Expand the Tag Browser and look expand the folder tree as shown below.  You should see the 'My Tag' tag published from the Ignition Edge MQTT Edge Node.
