IIoT Gateway vs Edge Computer vs Industrial Router: What’s the Difference?
Read more: IIoT Gateway vs Edge Computer vs Industrial Router: What’s the Difference?People ask me all the time: what’s the difference between an IIoT Gateway, an Edge Computer, and an Industrial Router? And honestly, I get why it’s confusing. Vendors love to mix these terms, and sometimes the same box gets called…

Top 10 IIoT Gateway Devices to Watch in 2026
Read more: Top 10 IIoT Gateway Devices to Watch in 2026Most factories are not fully “smart factories.” They are a combination of legacy assets that remain critical, newer equipment with restricted networks, vendor skids with limited documentation, quality systems requiring trusted data, IT teams enforcing security controls, and business stakeholders…

Why Edge Data Contextualization Is Key for AI in Manufacturing
Read more: Why Edge Data Contextualization Is Key for AI in ManufacturingIf you’ve ever tried to get meaningful insights from a plant’s data, you know the struggle. You wire up a sensor, push the data to the cloud, and… good luck figuring out if “Tag_123” is a temperature, a pressure, or…

IIoT at Scale: Containerization, Docker, and Kubernetes Explained
Read more: IIoT at Scale: Containerization, Docker, and Kubernetes ExplainedI’ve spent the better part of two decades watching manufacturing tech evolve from isolated systems to today’s cloud-connected, agile factories. Lately, the biggest leap I’ve seen is how containerization (with Docker and Kubernetes) is making it easier to scale IIoT…

Equipment Connectivity: The Unglamorous Work That Makes Everything Possible
Read more: Equipment Connectivity: The Unglamorous Work That Makes Everything PossibleIf you’ve ever walked into a modern factory and seen dashboards glowing with real-time data, robots humming along, or operators using tablets to check production status, you’ve seen the shiny side of smart manufacturing. But behind all that magic, there’s…

Edge AI Is Transforming IIoT with Real-Time Decisions
Read more: Edge AI Is Transforming IIoT with Real-Time DecisionsLet’s break it down simply. Edge AI means running artificial intelligence—things like machine learning models—directly on devices at the “edge” of your network. That’s usually right where the machines, sensors, and cameras are, not in some far-off data center. Why…

MQTT Quality of Service (QoS) Explained
Read more: MQTT Quality of Service (QoS) ExplainedIf you work in manufacturing or IIoT, you’ve probably heard the term “MQTT Quality of Service” (or just MQTT QoS) thrown around. It sounds technical, but it’s actually a pretty simple idea — it’s about how sure you want to…

Model Context Protocol (MCP) Explained: Making IIoT Smarter
Read more: Model Context Protocol (MCP) Explained: Making IIoT SmarterIf you work in industrial automation or manufacturing, you know the pain of getting data from machines, sensors, and systems into the hands of people and AI tools that can actually use it. The Model Context Protocol (MCP) is a…

Birth Certificates for Machines: How Sparkplug NBIRTH Messages Work
Read more: Birth Certificates for Machines: How Sparkplug NBIRTH Messages WorkLet’s talk about something I see a lot in real-world industrial IoT projects, but that’s rarely explained in plain English: Sparkplug NBIRTH messages. If you’ve heard the phrase “birth certificate for machines,” that’s what we’re talking about. These NBIRTH messages…

IIoT Journey: Edge-First, Cloud-Second
Read more: IIoT Journey: Edge-First, Cloud-SecondI want to talk about why, after two decades in Industrial Smart Manufacturing, I’ve become a strong believer in an “Edge-First, Cloud-Second” approach for connecting plants, machines, and people. This isn’t some theory — it’s the result of real projects,…

Foundations: What Is a PLC in an IIoT Architecture?
Read more: Foundations: What Is a PLC in an IIoT Architecture?Let’s start at the beginning: what’s a PLC, and why does it matter so much in smart factories and IIoT (Industrial Internet of Things) setups? The Basics: What Is a PLC? A PLC, or Programmable Logic Controller, is basically the…
