At this point, the application will start, connect to the MQTT server, publish a Edge Node Birth Certificate, publish a Device Birth Certificate, and begin periodically reporting random data values to Ignition via MQTT Engine.  This can be verified via Ignition Designer.  Using a Web Browser, browse to the Ignition Gateway on your Ignition Gateway.  If it is running on your development machine, that is: http://localhost:8088.  You should see this:

You will see the result of MQTT Engine seeing a new edge node and device connect to the MQTT Server and publish an NBIRTH and DBIRTH message.  As a result, MQTT Engine created the Ignition Tags shown above.  These are also dynamically updated as the values change.  You can also write to the outputs.  This can be done by putting designer into read/write and preview mode.  Do so by clicking this button in the menu to enable read/write mode:

Then you can change any of the values on the outputs here:
