New Who's groovin' video series lets you preview a variety of industrial application challenges and solutions.

When you’re working through a control or monitoring problem, it helps to see how someone else already solved something similar.

That's the idea behind a new short video series called Who's groovin'.

Get a sneak peek.

Get class details and reserve your seat for one of the 2026 groov EPIC Premium Factory Training classes.

The first training class of 2026 just wrapped up at Opto 22 headquarters. It was a full class, which means word is getting out, and classroom PLC training is in demand!

Are you considering a system upgrade or just curious how groov EPIC compares to other systems you've used?  Do you need help configuring and programming hardware and software for your industrial automation or IIoT application? 

Then consider spending 4 days with us at Opto 22 headquarters learning all the programming options and features of groov EPIC, the Edge Programmable Industrial Controller.

January's group of students represented a variety of industries and provided some great feedback on their training experience. Take a look at what they said.

New case study shows you a simple way to digitally transform manual, disconnected underground systems into smart systems with full-scale, remote visibility.

Do you work on industrial applications in hazardous environments, where one failure can lead to immediate and severe consequences?

Watch recorded conference sessions for FREE and learn how to connect your systems with Node-RED.

Included in groov EPIC and groov RIO is Node-RED, an open-source software program that allows you to wire together devices, databases, cloud applications, and APIs (application programming interfaces) using simple logic flows.

Node-RED is being used in a wide range of mission-critical applications, from city utilities and semiconductor fabs to manufacturing lines and smart buildings.

Anywhere an engineer needs two systems to talk, Node-RED often shows up. It’s a visual way to move data, trigger actions, and link systems. Due to Node-RED's growing popularity, it's no surprise that last week's Node-RED conference provided some excellent resources and idea exchanges.
