With Ignition running and the AWS Injector module loaded and configured we can now open the Ignition Designer to create/observe the initial Tag structure.  Regardless of the OS Ignition is running on, there is a “Launch “Get Designer” button on the Ignition Gateway Console. From here you can launch your Designer on any machine.  This is shown below.  The default credentials for the designer are the same as the Gateway Console, admin/password.

Once you have logged into the Designer enter a new project name and open the project. The project name that we used for this tutorial is simply called “Tutorial1”“test”.

After Designer opens, you will see the default Designer screen as shown below.

With the AWS Injector module installed in Ignition, a new folder is created under the "All Providers" folder and is called “AWS Injector”. This folder will contain both information tags about the module's version and state, as well as control tags for refreshing the module and it's Tag Agents.

Next, we need to create a folder structure where we will create a virtual Edge device and some tags to be sent by the AWS Injector module.  When the AWS Injector module is installed in Ignition, a folder is automatically created in the Ignition tag structure with the following path:

• All Providers/default/Edge Nodes

Step 5: Use Ignition Designer to Create New Tags

For this tutorial, right click on the Edge Nodes folder and create a new folder called Tutorial Group. Then right click on the Tutorial Group folder and create another new folder called Tutorial Edge Node.  Finally, right click on the Tutorial Edge Node folder and create another new folder called Tutorial Device. This folder structure creates the same hierarchy that is described in the Sparkplug B specification of Group ID, Edge ID, and Device ID.Image Removed

With this folder structure in place, now we can create some memory tags of various data types to publish. Right click on the Tutorial Device folder and select ’New Tag’/’Memory Tag’. In the tag editor change the Name of the tag to “Boolean001”, and change the Data Type to Boolean. Follow this same procedure for new memory tags called “Integer001” of type Integer, “Float001” of type Float, and “String001” of type String. The resulting folder structure should look as follows.

Step 6: Use Ignition Designer to Send Tag Data (Current Tag Values)

Now that we have a folder structure with some tags we can refresh the AWS Injector module.  Make sure that the Ignition Designer has read/write communications turned on by selecting Project/Comm Read/Write.

To refresh the default Tag Agent with the folder structure we’ve created, open the folder "All Providers/AWS Injector/AWS Injector Control" and click on the Refresh Boolean. Note the Boolean tag will not change to true. This is really a one-shot and as a result, the tag will not change to true.

When this happens, the Tag Agent will scan the "Edge Nodes" folder and find the new Memory Tags that we have created, construct messages representing those tags with their current values and send the messages to the Kinesis Stream and/or DynamoDB Database that we have configured.
