Watch this new video for a concise explanation of why today's industrial control projects require a flattened technology stack.

Are you facing application challenges like shorter deadlines, tighter budgets, and smaller teams? Are you dealing with legacy equipment that increases your cybersecurity risk and makes it almost impossible to access the data you're being asked for? 

groov EPIC edge controllers and groov RIO edge I/O modules were designed to help overcome these challenges.

Opto 22 VP of Product Strategy, Benson Hougland, breaks it all down for you in this new video. See why edge-based automation can help you get data across your organization quickly, securely, and confidently.

Bookmark the new Articles section of the Opto 22 website for white papers and editorial content covering the latest technology in the world of industrial automation.

Industrial automation is evolving quickly. New technologies, communication standards, and cybersecurity challenges are constantly changing how engineers design and maintain systems. When you’re working on a project, you don’t always have time for tedious research.

That's why we've created a new section of the Opto 22 website that gives you practical information you can use right now.

See what you'll find in the new Articles menu option.

New white paper outlines actions you can take for practical and cost-effective machine monitoring with edge devices.

Keeping machines running smoothly is at the heart of every industrial operation. Machine monitoring helps avoid downtime by providing real-time insights needed to catch problems early and keep equipment working.

Have you been tasked with an IIoT (industrial internet of things) or digital transformation initiative for your company? Ready to learn how edge devices can be a part of your solution?

Listen in on a conversation from this year's ProveIt! conference as Benson Hougland discusses the why and how of securely moving data from OT to IT systems with the Manufacturing Hub podcast.

Have you tuned in to the Manufacturing Hub podcast yet? It's an educational show hosted by two longtime industrial practitioners—Dave Griffith and Vladimir Romanov. They asked Opto 22's Benson Hougland for a sit down discussion at this year's ProveIt! conference in Dallas, where several topics were covered.

What types of solutions are readily available for manufacturers to start their digital transformation? What are the most common challenges and roadblocks? What does the future look like in terms of product features?

And most importantly, was Opto 22 able to prove a viable solution on stage at the ProveIt conference?

New video provides some practical solutions to consider in the age of TCP/IP.

Looking to digitally transform your operations, but your existing machines don't support newer protocols like MQTT or OPC UA?

Don't worry, you're not alone. Legacy industrial control systems are still operating everywhere today. But don't settle or wait for them to fail. 

It's time to learn more about modern edge devices that can bridge the gap between old and new.

This new 1-minute video is a great conversation starter on the topic.

Without disturbing existing systems, edge devices make it easy to convert data from a custom fieldbus into open protocols for digital transformation.

If TCP/IP won the “protocol wars” in the ‘90s, then WHY are you still fighting protocol battles on the plant floor today? Because industrial networks were around long before the internet. As far back as the 1960s, machines communicated via serial networks like RS-232, RS-485, and CAN Bus—with specialized proprietary fieldbus protocols like Modbus, Profibus, and DeviceNet.

Even with TCP/IP on Ethernet, specialized protocols remained. Modbus now has a TCP/IP version, Profibus gave way to ProfiNET, DeviceNet to EtherNet/IP, and even some new ones joined the protocol party.

After the industry demanded interoperability, OPC was born—now OPC UA—a big step toward a unified architecture on OT networks. Meanwhile on the IT side, using HTTP and HTTPS was common. It’s how web browsers—and most of the internet—work today.

MQTT Sparkplug came later. A recently named International Standard, it’s built on efficient, secure, and scalable publish/subscribe communications—a great fit for digital transformation projects and the IIoT.
