The recording of this webinar can be found here: https://www.youtube.com/watch?v=LTkpqw7NszE&feature=youtu.be A key challenge of IIoT deployments is integrating and sharing data between different systems and services. Many IIoT architectures become a complex set of integrations between hardware devices and software services. Even with MQTT as the hub of an IIoT system, true interoperability can be difficult to achieve. Sparkplug is an emerging new specification built on top of MQTT that aims to break down the data silos created by pairwise integrations commonly found in IIoT architectures. Where MQTT allows for IIoT systems to decouple operations data from specific applications, Sparkplug defines a common format for MQTT data exchange that promotes plug 'n play interoperability between hardware solutions and software solutions. In this webcast, we will introduce the key concepts of MQTT Sparkplug and show how it can promote simplified IIoT architectures. We will also do a live demonstration that will showcase connecting industrial field devices to HiveMQ's MQTT broker using the Sparkplug client embedded in Opto 22’s groov RIO edge I/O and then visualize Sparkplug messages in an enterprise time-series database. In just 15 minutes we will demonstrate the simplicity of creating plug ’n play interoperability for IIoT solutions.

Challenges
• Difficult to change workflows and
processes
• Difficult to setup a new system/facility
• Difficult to analyze data across the
entire system

Decoupled Architecture

9. Copyright © by HiveMQ. All Rights Reserved.
• Decoupled clients and broker
• Publish/Subscribe protocol
• Extensible
• Reliable

Pub/Sub Pattern

But There Are Still Issues
• Devices and endpoints have different
topics, payloads and data structures
• Applications assuming specific formats
and structure
• Data agnostic - payload must be
interpreted but no context

INTRODUCING
A simple, open specification, that will enable
plug and play interoperability between IIoT
devices and IIoT applications.
Sparkplug Defines:
● Topic namespace
● Data Model and Structure
● Extensible process variable
payload
● Defines MQTT state management

13. Copyright © by HiveMQ. All Rights Reserved.
KEY CONCEPTS
● Continuous Session Awareness
● Report by Exception
● Interoperability by consistent data
format
● Auto Discovery

SCADA /
IIoT Host
● Application responsible for monitoring
and control MQTT EoN node
● Maintain continuous session state
awareness of all participants (machines,
devices, PLCs, sensors, gateways and
applications)
● Not responsible for establishing or
maintaining connections directly to the
device
● In Sparkplug, devices, EoN and SCADA/
IIoT Host connect to central MQTT
broker to publish and subscribe to data;
allowing report by exception

EDGE OF
NETWORK (EoN)
NODES
● EoN provide physical and logical
gateway function for devices that don’t
implement Sparkplug
● EoN manage the state and session of
itself and the connected sensors
● EoN allows devices that implement
protocols like OPC-UA, Modbus, and
proprietary PLC to connect to a
Sparkplug architecture

17. Copyright © by HiveMQ. All Rights Reserved.
DEVICES/
SENSORS ● Devices and sensors are the key
endpoints in any industrial automation
system
● Devices and sensors connect with EoN
that bridge the data from these devices
into the Sparkplug protocol

MQTT
APPLICATION
NODES ● MQTT Application Nodes can produce
and consume Sparkplug messages but
don’t act as a SCADA / IIoT Host.
● Typically Application Nodes are MES,
Historians, Analytics systems

19. Copyright © by HiveMQ. All Rights Reserved.
MQTT BROKER ● MQTT broker is the central data
distribution point in a Sparkplug
architecture
● MQTT broker requirements:
○ 100% compliant to MQTT 3.1.1
○ Requires features like Retained
Messages, Last Will and
Testament and QoS
○ Not all MQTT brokers support
these features: MS Azure IoT Hub
and AWS IoT can’t be used with
Sparkplug

HiveMQ MQTT Platform
● High availability
● 100% MQTT compliant
● Scalability
● Observability
● Enterprise Security
● Integration with OT/IT
Systems
