New case study shows you how Optimum Technologies overcame a lack of experience in industrial controls to quickly build an entirely new thermal vacuum facility.

Can you build a sophisticated test and control system in just one week—with no controls experience?

Optimum Technologies did. Discover how they used groov EPIC to quickly build a thermal vacuum test system, streamline data collection and control, and even uncover a problem with their new test chamber.  

Get the details from this new case study, and see what you can take away for your own automation project.

New case study explores a city's need for real-time visibility of its critical infrastructure—all through remote monitoring.

When you’re responsible for critical infrastructure spread across a city, knowing what’s happening at every site can be a major challenge.

For Kuala Lumpur’s River of Life project, operators needed real-time visibility into 25 remote pumping and treatment sites—without relying on routine site visits to discover problems.

A practical guide for learning about Proportional Integral Derivative (PID) loop control and tuning.

PID loops are everywhere in industrial automation—but getting them tuned for fast, stable, and efficient control can be a challenge.  

This new technical article defines the elements of a PID loop, reviews how PIDs are configured for Opto 22 devices, and introduces a free online tuner you can use for many loop controllers (not just Opto's). 

A maintenance release: a few enhancements, one security patch, an updated Java runtime, current Ignition and Cirrus Link versions, and some bug fixes.

If you use or plan to use groov hardware, you’ll want to be aware of this small but important firmware release.

Firmware 4.1.3 handles upkeep and a few small enhancements: a web server security patch, current Ignition and Cirrus Link versions, and fixes for hostname registration, backup restores, and USB port control.

It’s available for every groov EPIC and groov RIO device ever shipped!

Here's what's in it and what each item means for your application.

The October 2026 groov EPIC Premium Factory Training class offers you a bonus workshop on advanced CODESYS programming topics.

Are you considering a controls 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?  

Here's your chance to attend factory training for the groov EPIC system—plus an additional workshop that offers more training on advanced features of the CODESYS programming option (included in EPIC).

Get all the details on the last Opto 22 training class of 2026.

The upcoming EVO Expo provides two days of training, live demos and direct access to industrial automation manufacturers.

Are you trying to solve a specific industrial application challenge? Are you trying to keep up with new technology trends or looking to expand your industry network? 

These are all reasons you'll want to attend the EVO Expo, October 6 - 7, 2026—hosted by OptoPartner EVO Integration.

Get all the event details and see how the expo aims to give you a hands-on, practical way to stay ahead in industrial automation and manufacturing. 

Last month's water-utility attacks hit exposed PLCs. Here's how to tell if yours is one, and how to take it offline for good.

Somewhere in your plant or remote infrastructure, a controller might be reachable from the public internet right now.

Someone probably set up remote access years ago so they wouldn't have to drive an hour out to a remote site every time it needed a look.

Nobody circled back. For a long time, that felt harmless. Last month, it stopped feeling that way.

Tune in to episode 12 of the Ignited podcast for real conversations on edge applications making a difference in very different industries.

Industrial automation is changing fast, but some of the biggest challenges remain surprisingly familiar: connecting equipment, getting useful data where it needs to go, and building systems that don’t box you in later.

Edge solutions are increasingly helping solve those challenges in both greenfield and brownfield systems. But don't you want to see what that actually looks like in practice?

Listen in as Opto 22's Dan White sits down with the Inductive Automation Ignited podcast team to break down four simple edge application stories that led to huge results.

Get details and specifications for two newly released groov I/O modules: GRV-ODCIHC-12 and GRV-ODCIHV-12.

Explore more options for your groov EPIC system with the release of two groov DC output modules.

Do your applications require driving high-current or high-voltage DC loads? Take a closer look at how these new I/O modules can help.

New article clarifies when to use sinking and sourcing in discrete DC circuits.

If you've ever hesitated when selecting digital I/O because of the terms sinking and sourcing, this new article can help.

It's a common point of confusion in industrial automation. Choosing the wrong module can lead to unnecessary troubleshooting, rewiring, or project delays.

The article and the accompanying tech note cover the basics: what's the difference, when it matters, and how you choose and wire the right I/O module.
