Industrial automation insights
Engineering perspectives on the future of manufacturing.
Building an IIoT Roadmap That Actually Delivers ROI
Most industrial IoT initiatives stall in pilot purgatory. Here's the staged framework Nexa uses to move plants from connected sensors to measurable ROI in 9 months.
PLC vs PAC: Choosing the Right Controller in 2026
Programmable Automation Controllers blur the line with industrial PCs. A pragmatic engineering comparison covering scan time, IEC 61131 compliance, motion control and total cost of ownership.
Predictive Maintenance: From Sensors to Savings
We deployed 4,300 vibration sensors across a refinery. Here is the data on what predictive maintenance actually saves — and the three mistakes that quietly kill the program.
Securing the Convergence of OT and IT
IT security frameworks don't translate cleanly to plant floors. A practical, ISA/IEC 62443-aligned framework for protecting industrial control systems without breaking production.
SCADA Modernization Without Stopping Production
A step-by-step migration pattern that replaced a 22-year-old SCADA across 14 sites — without a single planned outage. Parallel-run, tag mapping, and operator change management explained.
Calculating Real ROI on Industrial Robotics
Robot vendors quote 18-month paybacks. Our 6-axis deployments average 14 — but only when you account for changeover time, quality cost and floor-space reclaim. A real-world ROI worksheet.
