Sparkplug B is an industrial IoT data transfer specification built on MQTT 3.1.1. Sparkplug B provides a unified way for device manufacturers and software providers to share data by making MQTT networks state-aware and interoperable while ensuring flexibility and efficiency.
Data collected by Neuron from devices can be transferred from the edge to the Sparkplug B application via the Sparkplug B protocol, and users can send data modification commands to Neuron from the application. sparkplug B is an application-based protocol running on top of MQTT, so the setup in Neuron is similar to the MQTT driver.
Parameters
| Parameter | Description |
|---|---|
| Client ID | MQTT client ID, a unique identifier for the connection |
| Group ID | The top-level logical grouping in the Sparkplug B protocol, which can represent entities such as factories or workshops |
| Node ID | Unique Identification of Edge Nodes in Sparkplug B Protocol |
| SSL | Whether to enable mqtt ssl, default false |
| Broker Host | MQTT Broker Host |
| Broker Port | MQTT Broker Port |
| Username | Username to use when connecting to Broker |
| Password | Password to use when connecting to Broker |
| CA | Ca file, enabled only if the ssl value is true |
| Client Cert | Cert file, enabled only if the ssl value is true |
| Client Key | Key file, enabled only if the ssl value is true |
| Keypass | Key file password, only enabled if ssl value is true |
TIP
Only the Group ID and Node ID are from the Sparkplug B specification, the rest are connection parameters of the MQTT Broker, see MQTT Overview.
