| Introduction to HiveMQ
• Founded in 2012, based outside of Munich
• HiveMQ helps move data to and from connected devices in an
efficient, fast and reliable manner
• 130+ customers with production IoT applications

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

| Decoupled Architecture

11.
| Decoupled clients and broker
| Publish/Subscribe protocol
| Extensible
| Reliable

| Pub/Sub Pattern

13.
| 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

14.
A simple, open specification, that will enable plug and play
interoperability between IIoT devices and IIoT applications.
Introducing Sparkplug
Sparkplug defines:
● The Topic namespace
● A Data Model and Structure
● An extensible process variable payload
● MQTT state management

15.
KEY CONCEPTS
Sparkplug
● Continuous Session Awareness
● Report by Exception
● Interoperability by consistent data format
● Auto Discovery

16.

| Sparkplug enabled Architecture

17.
● Ideal for real time data
● Direct Integration
● Includes Monitoring Dashboard
● Could Replace Historian and Analytics

| Sparkplug Scenario - what was visualized
All Participants send data in a predefined protobuf schema
Devices forward Data to an
EoN
The topic structure is predefined namespace/group_id/message_type/edge_node_id/[device_id
]
The message types are predefined
