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).

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.

Catch the replay of this recent Automation Ladies podcast that explores real-world use cases and practical approaches to using edge automation.

Have you been locked in to proprietary systems on your plant floor? Are you looking for open source solutions without all the hidden costs?

Opto 22's Dan White joins the Automation Ladies podcast to discuss open source architectures, the switch to edge computing in manufacturing, and the pain points that force engineers and technicians to seek solutions like groov edge devices.

The Who's groovin video series is back with episode 9 and the key to monitoring radioactive waste when every second is critical.

Have you ever been involved in a controls project that was a patchwork of competing vendors and systems?

Or have you been faced with the task of integrating different systems into one platform that scales?

In this edition of Who's groovin, see how a Bulgarian engineering firm took a radioactive waste facility from mismatched hardware to a single unified SCADA platform.

Watch:

Take advantage of several new features, fixes and improvements in this latest release of the PAC Project software suite, R10.6002.

Whether you use Opto 22's basic or professional version of the PAC Project Software Suite, you'll want to hear about some new features and enhancements just added to PAC Control as well as some fixes for PAC Display.

Let's review the highlights.

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.
