At this point, the Central Ignition Gateway with MQTT Distributor, MQTT Engine, and MQTT Recorder is fully configured and ready to receive MQTT Sparkplug messages from the Remote/Edge Ignition Gateway.  MQTT Distributor listens on TCP port 1883 by default for inbound MQTT connections.  Make sure the Operating System's Firewall, Antivirus, and Malware protection services allow inbound connections on port 1883/TCP before proceeding.

Remote/Edge Ignition Gateway Setup

With the Central Ignition Gateway ready to receive MQTT/Sparkplug RECORD objects, the EFM ABB Totalflow and MQTT Transmission modules can be configured on the Remote/Edge Ignition Gateway. 

Start by configuring the MQTT Transmission module. Do so by opening Ignition Designer and creating a tag structure similar to what is shown below.

Note this structure is based on usage of the 'Default Transmitter' in MQTT Transmission.  So, the directory structure is very important.  Note the structure.

  • tag provider/Edge Nodes/[Group ID]/[Edge Node ID]/[Device ID]/...

In the example below this implies the following definitions:

  • [Group ID] = G1
  • [Edge Node ID] = E1
  • [Device ID] = Totalflow G4 Sim

These exact values will be used for the EFM ABB Totalflow connection Sparkplug parameters to tell the EFM ABB Totalflow which MQTT Transmission Transmitter configuration to use and, in turn, which MQTT connection to use to send the history data on.

Next the MQTT Transmission server configuration must be modified to point to the Central Ignition Gateway we set up earlier.  To do so, in the Ignition Gateway Web UI browse to the Configure tab on the top and then to MQTT Transmission Settings in the lower left as shown below.

In the MQTT Transmission Settings configuration, click the Servers tab.  Then click 'edit' on the Chariot SCADA MQTT Server definition.  Modify the URL to match the URL of the Central Ignition Gateway.  In this example, MQTT Distributor is installed on a Central Ignition Gateway at the IP address of 192.168.1.2.  Once the URL is modified to match the configuration, there should be a '1 of 1' in the Connected column as shown below.
