How to Add Data Sources

Once the data model is built under Namespace, you need to connect real data to the model for subsequent processing and use.

Adding Data Flow Manually

1. Log in to supOS, go to UNS > SourceFlow.

Index	Item	Description
1	Name	Click the flow name to start editing the data flow.
2	Flow Operations	Copy / Edit / Delete the data flow.
3	Search	Search for existing data flows.
	New SourceFlow	Add a data flow.

2. Click New SourceFlow, enter a name and click Save.
3. Click the flow you just added, and drag in nodes according to your data source type (e.g.modbus).
4. Drag in an mqtt out node, and finish its configurations.

1. Add the internal broker via emqx:1883.

   

2. Set its subscription topic to the data model in Namespace.

   For example, the data model structure is factory/equipment/cnc, the topic will be factory/equipment/cnc.

   

5. Click Deploy at the upper-right corner, trigger the flow and the data will be sent to corresponding model under Namespace.

Configuring Data Source through Generated Flow

1. Log in to supOS, go to UNS > Namspace, and under the Model tab, select a file.
2. Scroll down to Topology, click the icon on SourceFlow to redirect to the generated data flow under SourceFlow.

3. Change the data source of the generated flow.

info

Make sure the returned data of the source node is JSON object. Currently, supOS can only parse this data type.

4. Delete the mock data node and connect the source node to the rest of the flow.

5. Click Deploy at the upper-right corner, and then trigger the flow.
6. Go back to Namespace, check whether the data is sent back to the file (data tag).
