This Quickstart document covers how IoT Bridge can be used to consume MQTT Sparkplug data and create and update data in Snowflake. This will show how to configure IoT Bridge as well as show how to use Inductive Automation's Ignition platform along with Cirrus Link's MQTT modules to publish device data to an MQTT Server. This data will ultimately be consumed by IoT Bridge to create and update the Snowflake components. This tutorial will use the AWS IoT Core Cirrus Link Chariot MQTT Server implementation. However, IBSNOW does work with any MQTT v3.1.1 compliant MQTT Server including Cirrus Link's MQTT Servers.

...

With Ignition and MQTT Transmission installed, we can configure the MQTT Transmission module to connect to AWS IoT Core using the same certificates Chariot MQTT Server 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, our tags are configured. A UDT definition will map to a model in Snowflake and UDT instances in Ignition will map to Snowflake. But, before this will happen we need to point MQTT Transmission to AWS IoT Corethe Chariot MQTT Server. To do so, browse back to the Ignition Gateway Web UI and select MQTT Transmission → Settings from the left navigation panel as shown below.

...

Now click the 'edit' button to the right of the 'Example Transmitter'. Scroll down to the 'Convert UDTs' option and uncheck it as shown below. This will also un-grey the 'Publish UDT Defintions' option. Leave it selected as shown below.

Then select the 'Servers' tab and 'Certificates' tab as shown below.

Now upload the three certificate files that were acquired during the AWS IoT thing provisioning. Upload all three to the MQTT Transmission configuration. When done, you should see something similar to what is shown below.

Now switch to the 'Servers' and 'Settings' tab. Delete the existing 'Chariot SCADA' pre-seeded MQTT Server Definition. Then create a new one with the following configuration.

• Name
  • AWS IoT
• URL
  • Your AWS IoT Endpoint URL of the form ssl://ENDPOINT_URL:8883
• CA Certificate File
  • The AWS Root CA certificate
• Client Certificate File
  • The AWS client certificate for your provisioned 'thing'
• Username
  
  • Your username for the Chariot MQTT Server connection
• Password
  • Your password for the Chariot MQTT Server connection
  Client Private Key File
  • The AWS client private key for your provisioned 'thing'

When complete, you should see something similar to the following. However, the 'Connected' state should show '1 of 1' if everything was configured properly.
