How to Build a Data Model

Based on simple folder-file structure, you can define the data hierarchy to a tree map.

Building Models Manually

Note

factory/equipment/CNC will be used as an example, in which factory and equipment are paths and CNC is a topic.

1. Log in to Tier0, select UNS.
2. Hover over the upper-right corner icon > New Path to add a path factory.
3. Enter the path name factory, click Create.
4. Select factory, hover over the same icon and add another path equipment under it.
5. Select equipment, hover over the same icon > New Topic, and add a topic CNC under it.
6. Set the topic Name, Type, select Enable History/Mock Data*, click the arrow to continue.
7. Set the payload fields, click Create to finish the topic creation.

Different selections

When the Topic Type is set to State or Action:

• Mock Data: Select it to generate mock data flow for testing.
• Enable History: Select it to store the data in Tier0 database.

Importing Models

• By JSON text
  1. On the UNS page, click the upper-right corner icon Import.
  2. Select the JSON tab, wirte JSON text on the window.
  3. Click Submit to import the model.
• By JSON file

4. Click the flow you just added, drag in nodes according to your data source type (e.g.modbus) on the canvas.
5. Drag in an mqtt out node, select the Server as emqx.
6. Enter the topic name copies from UNS (e.g. factory/equipment/CNC), click Done.
7. Click Deploy at the upper-right corner, trigger the flow and the data will be sent to corresponding model under UNS.
