Basic Message Components
Topic
The topic is published in the format spBv1.0/[Group ID]/[Message Type]/[Edge Node ID]/[Device ID] where:
Group ID
This identifies a logical grouping of Edge nodes and devices. This can be a region, a facility name, or any meaningful grouping of Edge Nodes within your application.
- Message Type
The message_type component of the topic namespace signals how the MQTT payload should be processed. The following message_type components are defined for the Sparkplug topic namespace:
CL Modules Sparkplug message types and how they differ: Edge node BIRTH certificate. This is a startup message from an Edge node to announce its presence and share its configurations.
CL Modules Sparkplug message types and how they differ: Notification of an edge node’s disconnection or failure.
CL Modules Sparkplug message types and how they differ: Device BIRTH certificate. This is a startup message from a device to announce its presence and share its configurations.
CL Modules Sparkplug message types and how they differ: Notification of a device’s disconnection or failure.
CL Modules Sparkplug message types and how they differ: Data messages from an edge node which include edge node metric data.
CL Modules Sparkplug message types and how they differ: Data messages from a device which include device metrics.
CL Modules Sparkplug message types and how they differ: Command to an edge node.
CL Modules Sparkplug message types and how they differ: Command to a device.
CL Modules Sparkplug message types and how they differ: It represents the state of the primary host application. Edge nodes subscribe to it to get the online status of the host.
- Edge Node ID
- The ID of the logical Edge Node. This is often the name of the system running Ignition with MQTT Transmission or Injectors.
- Device ID (Optional)
- The ID of a device attached to the Ignition instance. This can be a PLC or logical grouping of tags that represent a physical or logical device connected to Ignition.
Payload
The payload contains the following :
- timestamp
- The time stamp the payload was created
- metrics
- An array containing data specific to the message type being published
- Parameters include:
- name
- Set to null in DATA messages if aliasing used
- timestamp
- dataType
- value
- alias
- Set to null if aliasing not used
- isHistorical
- Flag denoting the metric represents a historical value
- Set to null for live data and True for historical data
- isTransient
- Not used in Cirrus Link modules
- Set to null
- isNull
- Flag denoting the metric has a null value
- metaData
- Included in BIRTH messages
- Includes Tooltip and Documentation if they have been changed from the Ignition default. See the Ignition Tag Properties reference for all available properties.
- properties
- The Quality property
- May be included in BIRTH and DATA messages
- If the Quality property is not included, the quality of the tag data is considered Good. See the Ignition Tag Quality Code Reference for the Data Quality value reference
- Additional property values
- Included only in BIRTH messages
- Included if they have been changed from the Ignition default or if they are custom properties. See the Ignition Tag Properties reference for all available properties.
- The Quality property
- name
- seq
- The message sequence number used to ensure that messages are processed in the correct order
- uuid
- Set to null
- body
- Set to null
