How Toyota and MTNA Cut Operations Data Complexity with MQTT Sparkplug and Unified Namespace Architecture

Learn how these manufacturers eliminated hours of wasted time by unifying data from fragmented systems using MQTT Sparkplug, with Toyota leveraging Inductive Automation’s Ignition platform and MTNA deploying Opto22’s groovRIO, and both proving the value of their low-cost approach before scaling enterprise-wide.

Key Highlights

Toyota eliminated 240 hours of monthly waste per site by creating a unified data layer that lets engineers access all systems from a single interface instead of logging into dozens of separate platforms.
Both companies proved their concepts with minimal investment. MTNA used a single injection molding machine and Raspberry Pi, while Toyota piloted one production line before rolling out enterprise-wide solutions.
MTNA connected old PLCs without Ethernet using universal I/O systems at roughly $1,000 per machine, while Toyota built abstraction layers to connect more than 500+ existing applications without replacing infrastructure.
