Azure IoT Device

Click Azure IoT Edge. You can enable/ disable the Azure IoT Edge.

Note that you will need to register an Azure account to be able to manage the Azure IoT Device for your IoT application.

To create the Azure IoT Device connectivity, following the steps below:

  1. Click img to set connection.
  2. Enter Connection String.
  3. Select a connection protocol.
  4. Select an authentication Type.

    When using x509 authentication Type, you only need to put the hostName(FQDN) in the connection_string of configuration. TPE will automatically complete the connection string in the following format.

    • device id: from the cn of subject in x509 certificate.
    • iothub name: the connection string parameter you set. 
    Hostname={iothub name}.azure-devices.net;DeviceID={device ID};x509=true
  5. (Optional) Upload X.509 Certificate and Private Key.
  6. (Optional) Upload a trusted root CA to connect to a transparent gateway (e.g. Azure IoT Edge)
  7. Click SUBMIT.

Telemetry Message​

The simplest message type for sending IoT device data to your IIoT applications is a telemetry message. To create a telemetry message, do the following:

  1. In the CLOUD CONNECTIVITY section, select a cloud service provider.
  2. Click on the Telemetry Message tab.
  3. Specify an Output Topic name.
  4. Enter the Polling Interval in seconds.
  5. Setup a threshold by file size (bytes) or time interval (seconds).
  6. Click NEXT.

img 7. Select tags from provides (e.g., Modbus Master).
8. (Optional) Enable custom payload by using the jq filter.
9. Click NEXT.
10. (Optional) Enter Property Key and Value.
11. Click SUBMIT.

img Device-to-Cloud (D2C) message policy allows you to transform default payload to your desired payload schema via the jq filter. For additional information, refer to the jq website (https://stedolan.github.io/jq/manual/).

Store and Forward​

D2C messages can be cached in a specified location and sent to the cloud later. This feature will help you to keep the acquired data in a queue temporarily when the network between your IIoT Gateway and the cloud is disconnected and transmit them to its destination after the reconnection. To enable the function, click on the Store and Forward and select Enable Store and Forward. You can select a target disk and set a maximum storage cache, set a retention policy, and a TTL (Time to Live) value for the messages.
