### Watch Opto 22's Showcase from the Ignition Community Conference and see how easy it is to bring your plant's assets into Ignition for robust data and analytics.
Do you have critical assets operating outside Ignition?
When machine health, energy use, and environmental conditions stay dark, you find out about failures, wasted power, and downtime only after they've cost you.
At last month's Ignition Community Conference, Benson Hougland and Garrick Reichert took the stage for a live demo of how *groov* devices + Ignition can overcome these challenges simply and securely.
Partnering with 7 other technology platforms (thanks to open source standards), the demo walks you through the ACME Dynamite Factory architecture. The factory may be fictional, but the data is very real. Watch:

### Read the new case study to learn how a multi-site agricultural application gained modern controls, remote monitoring, and real-time visibility.
What does it take to turn a complex industrial challenge into a smarter, more effective solution?
DNR Systems and Boron Tech Solutions (BTS) are here to share their success story. A boron filtration system was working well at the local level, but it needed to be duplicated easily and securely on a much larger scale across hundreds of acres of farmland.
Get the details from this new case study on how DNR and BTS found the complete package to go end-to-end for fully managed SCADA to the cloud.

### 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.
See how their engineering team made a distributed infrastructure easier to manage.
