And as mentioned above if you are using the more robust method of specifying the host be sure to match Primary Host ID (eg. Ignition_Gateway) in Edge and Central Gateway settings.  Edit the 'Default' Sets to enter and update the Primary Host ID.

6: Launch Designer and Edit default Edge Tags

At this point we must download and launch the newest Ignition Designer tool to create or edit the default Tag(s) to send to MQTT Engine using the MQTT protocol.  Get Designer from Ignition Edge web portal as shown below.  Start and point the Designer tool at the same IP address, username and password as created on your Edge-Gateway to create your project.

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.Image Removed

Extra Activities

...

• TLS enable the MQTT Distributor module and disable port 1883
  • Note production MQTT Infrastructures should never run on the open Internet without using TLS enabled MQTT connections!
• Modify the MQTT Transmission default transmitter tag tree to add additional tags and get them to show up in the Central Ignition Gateway
• Write to a tag in MQTT Engine to show it update in MQTT Transmission
• Disable MQTT Transmission in Ignition Edge MQTT to see the tags go stale in MQTT Engine
• Set up store and forward in MQTT Transmission to show data being saved in Ignition Edge MQTT when the connection goes down
• Load and Configure a Database at the Central Gateway (launch Gateway webpage) then edit and associate Tag History using Ignition Designer
• Use a Custom Transmitter rather than the Default Transmitter to provide more flexibility on the MQTT Transmission side in terms of tag tree/arrangement
  • (show link here)
• Add a second or more Ignition Edge MQTT instances pointed at the same MQTT Distirbutor Distributor instance that was set up in this tutorial
