sudo /etc/init.d/ibassystemctl restart ibas

At this point, IBAS should connect to AWS IoT Core and be ready to receive MQTT Sparkplug messages. Verify by running the following command.

...

After doing so, you should see something similar to what is shown below. Note the last line is 'MQTT Client connected to ...'. That denotes we have successfully configured IBAS and properly provisioned AWS IoT Core.

Edge Setup with Ignition and MQTT Transmission

At this point IoT Bridge is configured and ready to receive data. To get data flowing into IBAS we'll set up Inductive Automation's Ignition platform along with the MQTT Transmission module from Cirrus Link. Begin by downloading Ignition here.

Installation of Ignition is very straightforward and fast. There is a guide to do so here.

With Ignition and MQTT Transmission installed, we can configure the MQTT Transmission module to connect to AWS IoT Core using the same certificates that we provisioned earlier. Begin by clicking 'Get Desginer' in the upper right hand corner of the Ignition Gateway Web UI as shown below.

At this point, data should be flowing into AWS SiteWise. By tailing the log in IBAS you should see something similar to what is shown below. This shows IBAS receiving the messages published from Ignition/MQTT Transmission. When IBAS receives the Sparkplug MQTT messages, it creates and updates asset models and assets in SiteWise. The log below is also a useful debugging tool if things don't appear to work as they should.

At this point, the asset models and assets have been created in AWS SiteWise as well. To see them, browse to the AWS Web Console and go to IoT SiteWise. Then click 'Models' using the left side pop-out navigation panel as shown below.
