As industrial systems become more connected, developers face a familiar challenge: integrating data across PLCs, SCADA, cloud platforms, historians, and enterprise applications without creating complex, hard-to-maintain architectures.
That’s why MQTT and Sparkplug have become key technologies for modern Industrial IoT.
MQTT provides a lightweight, publish/subscribe messaging protocol that’s ideal for distributed industrial environments. Its efficiency and flexibility have made it a popular choice for moving data between systems. However, flexibility alone doesn’t guarantee interoperability.
Sparkplug builds on MQTT by introducing a standard way to exchange industrial data. By defining consistent device state, metrics, and metadata, it eliminates much of the custom engineering traditionally required to connect equipment from different vendors.
For developers, the benefits are significant:
🔸 Faster system integration
🔸 Automatic device discovery
🔸 Standardised data models
🔸 Reduced maintenance
🔸 Scalable, vendor-neutral architectures
Instead of spending time managing bespoke interfaces, teams can focus on building applications that deliver real operational value.
As manufacturers continue investing in digital transformation, understanding open standards like MQTT and Sparkplug is becoming an increasingly valuable skill. Whether you’re developing edge applications, modernising legacy systems, or designing Industrial IoT solutions, these technologies provide a foundation for building connected systems that are reliable, scalable, and easier to maintain.
To explore these concepts in more depth, Arlen Nipper, co-creator of MQTT and President and Co-Founder at Cirrus Link Solutions, and Thomas Burke from Inductive Automation share their expertise in this technical webinar.
They discuss the thinking behind MQTT, why Sparkplug was developed, and how both technologies are helping developers simplify industrial connectivity.
If you’re looking to build more interoperable and future-ready industrial applications, it’s well worth exploring.
