View Data from a Manufacturing Connect Edge Instance and/or a Child Device
To view data from a Manufacturing Connect Edge Instance, at least one child device (connected device within the Manufacturing Connect Edge instance) must be properly set up. The child device must be connected with tags, and then the tags must be transformed as imported topics inside the Manufacturing Connect Edge instance's Default Generic MQTT SSL connector. This first child connection will facilitate the data connection between a Manufacturing Connect Edge instance and the Manufacturing Connect. Additional child device connections from a Manufacturing Connect Edge instance will append to the Manufacturing Connect Edge instance's data.
Note: Viewing a child device's messages works only for standard tags.
Using Manufacturing Connect, activate an edge device. See Create a Configuration and Activate an Edge Device for more details.
To use view data from an edge device and/or a child device, you will need to do the following.
- Step 1: Connect a Device with Tags in Manufacturing Connect Edge
- Step 2: Setup Default Generic MQTT SSL connector with imported Topics in Manufacturing Connect Edge
- Step 3: View Data in Manufacturing Connect
To jump to a specific section, refer to the Table of Contents on the right side and click the corresponding step.
Before data can be viewed for a Manufacturing Connect Edge Instance, a device must be first connected to the instance and then associated with tags. This allows the connected device's data to be extracted from the Manufacturing Connect Edge instance.
To connect a device with at least one tag:
Manufacturing Connect Edge : DeviceHub > Devices : Newly connected deviceAdd Tags to the connected device from the previous step.
Manufacturing Connect Edge : DeviceHub > Tag : Newly connected device
Step 2: Set Up Default Generic MQTT SSL Connector with Imported Topics in Manufacturing Connect Edge
After a device is connected with tags, the Default Generic MQTT SSL connector must be enabled. Then the generated tags earlier must then be transformed as topics to be immediately imported and enabled into the Default Generic MQTT SSL connector.
To set up Default Generic MQTT SSL connector with at least one imported topic:
Make sure that the Default Generic MQTT SSL connector is connected. See Manage Individual Connectors within Manage Connectors for details.
- Import the added tags from Step 1: Connect a Device with Tags in Manufacturing Connect Edge as outbound topics to the Default Generic MQTT SSL connector. See Connector Topics within Manage Connectors for details.
Enable the imported topics. See the Manage Connector Topics section in Manage Connectors for details.
Default Generic MQTT SSL connector with enabled imported tag as topic- (Optional) Edit the imported topics to assign user-friendly names.
Once a Manufacturing Connect Edge instance is connected to Manufacturing Connect and a device is added to that Manufacturing Connect Edge instance, you can view data (outbound messages) from that Manufacturing Connect Edge instance or that instance's (child device) in the Manufacturing Connect UI.
To access the data viewing UI in Manufacturing Connect:
- Log in to Manufacturing Connect.
- From the navigation panel, select Edge Management. The Edge Devices tab appears.
To view edge device data:
- From Edge Devices, click the ID of the edge device whose data you want to view. The Device Details pane appears.
- Click the Raw tab. The Raw Data pane appears.
- Toggle Auto-Refresh at the bottom of the pane.
- Select the refresh interval from the Interval drop-down list. The messages published by the topics you have added to the Generic MQTT-SSL connector in Step 2: Setup Default Generic MQTT SSL connector with imported Topics in Manufacturing Connect Edge appear on the pane. The list of messages is refreshed according to the interval you have selected from the earlier step.
To view child edge device data:
- Click the Show child devices icon next to an edge device. The child devices for the edge device drop down.
- Click the ID of the child device whose data you want to view. The selected device's information pane appears.
- Click the Explore tab. The Explore pane appears.
- Toggle Auto-Refresh at the bottom of the pane.
- Select the refresh interval from the Interval drop-down list. The topics you have added to the Default Generic MQTT SSL connector in Step 2: Setup Default Generic MQTT SSL connector with imported Topics in Manufacturing Connect Edge appear on the pane. Their Last Value and Updated At fields refresh according to the interval you have selected in the previous step.
- To see the list of values a topic has published since it began auto-refreshing, click Last Value for that topic. The values appear in the Edge Device Object value dialog box, in a tabular format.
- To display the same data as a chart, select the Chart tab.
Note: Once a child device's data has been published (and has become viewable) in Manufacturing Connect, you can visualize this data using Grafana. See Visualize Child Device Data Using Grafana.
