The aim of the session is to show how a modern and resource-saving industrial IoT architecture can be built with the help of MQTT Sparkplug, HiveMQ and InfluxDB. Starting with challenges in classic OT/IT systems, the concepts of Sparkplug will be explained, and the session will cover how they can be implemented with MQTT to fulfill requirements for a modern IIoT solution. Attendees will also learn the entire setup process.

| 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

4. © 2021 InfluxData. All rights reserved. 4
| HiveMQ Platform
● High availability
● 100% MQTT compliant
● Scalability
● Observability
● Enterprise Security

5. And the Gap between IT and OT
Status Quo in IIoT

6. © 2021 InfluxData. All rights reserved. 6
| Lots of Data Silos

7. © 2021 InfluxData. All rights reserved. 7
| Coupled Infrastructure

8. © 2021 InfluxData. All rights reserved. 8
| Siloed OT Systems - No Interoperability

9. | 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

12. © 2021 InfluxData. All rights reserved. 12
| 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. © 2021 InfluxData. All rights reserved. 16
| Sparkplug enabled Architecture

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

| 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
