Configure a destination node

更新时间:

After you configure a processing node, you can set up the destination node to define the final output of a Topic parsing task based on the output fields from the processing node.

Prerequisites

Ensure the source node is configured.

Background information

Procedure

  1. Access the data parsing workbench.

  2. In the middle canvas, click the add image icon following the current node.

  3. From the node list, single click Destination Node.

  4. On the canvas, single click Destination Node, and in the Destination Node panel, select the Destination Type and configure its settings.

    Important

    When Pass-through is set to Yes in the Format Parsing Source Node, the Target Type defaults to IoT Instance Topic and is not editable. For instructions on configuring the source node, see Configure the Source Node.

    Destination Type

    Description

    IoT Instance Topic

    Choose the Product and specify the Destination Topic.

    Only products and custom topics within the current instance are available for selection.

    The panel also displays the Output Data Format configured in the preceding node.

    IoT Instance Custom Storage Table

    Select an existing Custom Storage Table.

    If no custom storage table exists, create one first. For details, see Create and manage custom storage tables.

    This panel also lists the output fields defined in the previous node.

    Important
    • If the selected table is empty, IoT Platform automatically populates it with fields based on the output field definitions.

      You can define the Metric Name, Unique Key, Data Type, Precision, Description, and other attributes as needed. Make sure these definitions match the custom storage table requirements.

    • If the table already has fields, the output fields must match the existing fields in the custom storage table, including the primary key. Otherwise, adjust the output fields in the preceding processing node to meet the custom storage table field requirements.

    For more details, see Manage custom storage tables.

    To view more details about the output fields, go to the Dataservice Studio > Data Metric page. For more information, see Data Metric Overview.

    IoT Twin Engine

    Select the Twin Engine Space.

    Only Enterprise or Ultimate Edition IoT Twin Engine Spaces within the current instance are available.

    Important

    The trial version of IoT Twin Engine is not available for selection (it appears grayed out). To use this feature, purchase the Enterprise or Ultimate Edition of IoT Twin Engine.

    After selection, the parsed data can serve as a data source for entities within the IoT Twin Space.

  5. To finalize, click Save in the upper-right corner of the Data Parsing Workbench.

    Note

    When using an API data source, add a field named ts in the node preceding the destination node. This field represents the Unix millisecond timestamp of data generation.

What to do next

After the destination node is configured, debug and publish the data parsing task. For more information, see Start a data parsing task.
