The Foundation Beneath the Foundation — OPC, OPC UA, and Why It All Starts Here

Before you can understand what makes Ignition powerful, you have to understand the standards it's built on. In this deep-dive fireside chat, Travis and Tom welcome Kevin Herron — one of the architects behind Ignition's OPC UA implementation — to decode the world of OPC and OPC UA from the ground up.   This isn't a marketing conversation. It's a technical one. Kevin walks through what OPC actually is, why OPC UA represented such a fundamental leap forward, and how OPC UA Part 5 and the Companion Specification Architecture give industrial software a shared language for describing data, behavior, and meaning — not just raw values. The conversation explores how Ignition was built with OPC UA at its core, what that means for interoperability, and why it matters whether you're a system integrator trying to simplify a deployment or an end user trying to achieve real digital transformation.   If you've ever heard "OPC UA" thrown around without a clear explanation of what it actually does — this is the episode that fills that gap.   Download a free trial of Ignition at inductiveautomation.com and connect to an OPC UA device or server on your own network — you'll see the data model in action within minutes. Then head to the OPC Foundation's website to explore Companion Specifications for your industry. And tune in for Episode 4, where we go beyond OPC to explore MQTT, Sparkplug B, and the edge compute revolution with two of the people who helped build those standards.
