NIAGARA SPARKPLUG
INTEGRATION

A smart, open-source Niagara integration

Sparkplug is an open-source software specification that provides MQTT clients the framework to seamlessly integrate data from their applications, sensors, devices, and gateways within the MQTT infrastructure in a bi directional and interoperable way. 

The Sparkplug specification describes a standard application layer protocol for applications, sensors, devices and gateways.

To achieve this the specification defines three clear goals, that are lacking from current MQTT and IoT implementations:
 

  1. Define a standard MQTT topic namespace

  2. Define standard MQTT state management

  3. Define the MQTT payload

Why Sparkplug?

​MQTT Sparkplug cuts the complexity and eliminates the mess, this means no challenges with complicated architectures and custom connections.

SINGLE SOURCE OF TRUTH

​Configure process variables one time at the source and deploy to the  entire enterprise
 

DECOUPLED DATA

​No longer maintain custom connections between various data sources
 

IMMEDIATE DISCOVERY

​New machine and sensor data becomes immediately available to all subscribers
 

INHERITED SECURITY

​Leverages TLS for data transport and requires no open port for edge network devices
 

STATE AWARENESS

​Birth and death certificates provide subscribing clients confidence in data validity
 

Differences between Sparkplug and plain MQTT

  • Sparkplug defines a clear topic namespace so applications know where to subscribe for data straight away

  • MQTT allows custom or vendor-specific topic namespaces so it can be hard to understand topics in a broker

  • Sparkplug defines a very strong message payload, with clear data types, metadata, datasets

  • MQTT has no definition of the payload it carries, MQTT only knows it carries a discrete number of bytes

  • Sparkplug defines how applications can become aware of the state of a Sparkplug node (state awareness) and specifies how applications are notified (by subscribing to a defined topic namespace) of the state of a node

  • MQTT contains no definition of state awareness of a node

  • Sparkplug enables loose coupling between all participants in a system by defining data formats upfront

  • MQTT contains no data formatting definitions so IoT solutions based on plain MQTT are tightly coupled causing design and deployment problems
