### 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.

### A new webinar series highlights the strong partnership between Inductive Automation Australia, Binford Tech, and Opto 22 to offer complete solution packages to customers in the region.

Australian engineers are increasingly asked to connect more systems, modernize aging infrastructure, improve cybersecurity, and deliver real IIoT results. Can you do it without ripping out existing systems that work?

This new two-part webinar series shows how you can.

Join Opto 22, Inductive Automation’s only hardware Premier Technology Partner, Inductive Automation Australia, and Australia-based distributor Binford Tech for a practical presentation on how modern industrial hardware can simplify secure edge deployment with Ignition.

### Listen to a recent episode of Inductive Automation's *Ignited* podcast to see how the open-source MQTT protocol has completely changed industrial data architectures.

Are you looking to build systems that move data—reliably and securely—across an enterprise? Have proprietary approaches slowed you down or locked you in?

Episode 4 of Inductive Automation's new *Ignited* podcast is a must listen! The co-inventor of MQTT, Arlen Nipper, and Opto 22 VP Benson Hougland are the featured guests on this podcast, reviewing industrial automation technology and taking you into the future.

Inductive Automation's Travis Cox and Thomas Burke host this discussion about why MQTT and Sparkplug B are now the key to scalable industrial data, and why edge computing changes everything.

Listen in on these insightful conversations:

### Watch the next episode in the *Who's groovin* video series and see how to build secure, resilient, and scalable SCADA systems.

Would you trust a SCADA system that takes five minutes just to confirm that a pump turned on? At the Genesee County Drain Commissioner’s Division of Water and Waste Services in Michigan, they didn’t have much choice.

In this edition of the *Who’s groovin* video series, see how Genesee County replaced slow radio polling with edge-based MQTT Sparkplug communications—giving their operators a real-time view of what’s happening at all of their 180 sites.

### New case study explains how Genesee County Drain Commissioner - Water & Waste Services solved their slow radio polling communication problem over 600 square miles.

Communication breakdowns in industrial systems aren’t just frustrating—they’re costly, disruptive, and often difficult to diagnose. 

The Genesee County Drain Commissioner Division of Water & Waste Service (GCDC-WWS) in Michigan struggled with the communication slowdowns in their legacy radio polling system. Poor alarming meant operators could not reliably fine-tune the pumping stations. With 180 remote sites across 600 square miles, these delays became unacceptable.

This new case study shows you how they solved the problem.

### Tips when using PAC Project with *groov* View, MQTT, Node-RED, RESTful API, and more

Are you wondering what else you can do to improve your PAC Project system’s performance? Did you optimize your SNAP PAC system and apply the same techniques to your *groov* EPIC system? There may be some other options you might not think of, like these:

-Moving *groov* View or MQTT to an alternate host task   
-Enabling only essential tags as "Public" for Ignition or MQTT   
-Scanning only PAC Control variables and tables if you’re using Node-RED

Whether you’re running an edge device like ***groov* EPIC** or a classic **SNAP PAC** system, performance optimization is a balance among logic, I/O communication, and HMI responsiveness. You might find some time savers in the [Optimizing PAC Project System Performance](https://www.opto22.com/support/resources-tools/documents/1776-optimizing-pac-project-system-performance-tec) technical note.

Here are a few highlights from the tech note.
