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.

If your goal is to get useful data from field devices and legacy systems, you’ve probably found that putting together an IIoT system is complicated, requiring many OT and IT devices, software, and protocols. But these 3 real-world case studies show how two tools—the MQTT communications protocol and industrial edge devices—can simplify your IIoT project.  [Read More](https://blog.opto22.com/optoblog/control-engineering-article-highlights-3-iiot-case-studies) 0 Comments [Click here to read/write comments](https://blog.opto22.com/optoblog/control-engineering-article-highlights-3-iiot-case-studies#comments-listing) Topics: [IIoT](https://blog.opto22.com/optoblog/topic/iiot), [MQTT](https://blog.opto22.com/optoblog/topic/mqtt), [cybersecurity](https://blog.opto22.com/optoblog/topic/cybersecurity), [MQTT implementation](https://blog.opto22.com/optoblog/topic/mqtt-implementation), [edge computing](https://blog.opto22.com/optoblog/topic/edge-computing), [control engineering](https://blog.opto22.com/optoblog/topic/control-engineering) ## [MQTT: Bringing it all together](https://blog.opto22.com/optoblog/mqtt-bringing-it-all-together) Posted by [Josh Eastburn](https://blog.opto22.com/optoblog/author/josh-eastburn) on Jul 29, 2020, 8:45:29 AM - [Tweet](https://twitter.com/share) [![](https://blog.opto22.com/hubfs/sparkplug-network.png)](https://blog.opto22.com/optoblog/mqtt-bringing-it-all-together) ### Building industrial MQTT networks at scale with Opto 22 *groov* devices.

At its heart, MQTT was designed for unreliable networks. Back in the ’90s, ConocoPhillips (now Phillips 66) was looking for a way to improve telemetry reporting over its low-bandwidth dial-up and costly VSAT (small satellite dish) SCADA network. IBM partnered with system integrator Arcom Control Systems (now [Cirrus Link Solutions](https://www.cirrus-link.com/)) to develop a minimalist communication protocol that could gracefully handle intermittent network outages and high latency among many distributed devices over TCP/IP.  [Read More](https://blog.opto22.com/optoblog/mqtt-mission-critical-fault-tolerance) 0 Comments [Click here to read/write comments](https://blog.opto22.com/optoblog/mqtt-mission-critical-fault-tolerance#comments-listing) Topics: [Node-RED](https://blog.opto22.com/optoblog/topic/node-red), [MQTT](https://blog.opto22.com/optoblog/topic/mqtt), [Ignition Edge](https://blog.opto22.com/optoblog/topic/ignition-edge), [groov EPIC](https://blog.opto22.com/optoblog/topic/groov-epic), [groov Manage](https://blog.opto22.com/optoblog/topic/groov-manage), [Sparkplug](https://blog.opto22.com/optoblog/topic/sparkplug), [MQTT implementation](https://blog.opto22.com/optoblog/topic/mqtt-implementation), [groov RIO](https://blog.opto22.com/optoblog/topic/groov-rio) ## [MQTT: Faster, better with Sparkplug B](https://blog.opto22.com/optoblog/mqtt-faster-better-with-sparkplug-b) Posted by [Josh Eastburn](https://blog.opto22.com/optoblog/author/josh-eastburn) on Feb 18, 2020, 3:30:40 PM - [Tweet](https://twitter.com/share) [![](https://blog.opto22.com/hubfs/opto-04-69-68_manage_local_sparkplug_configuration_combined.png)](https://blog.opto22.com/optoblog/mqtt-faster-better-with-sparkplug-b) ### In part 2 of our series, we look at how to set up *groov* Manage and Ignition Edge for publishing with Sparkplug B payloads. MQTT is the darling of enterprise IoT because of its efficiency, simplicity, and flexibility, which makes it ideal for use in applications that communicate with resource-constrained edge-of-network devices. After being nurtured for years within IBM, and incorporated into their smart energy, health, and utilities solutions, MQTT has become the chosen messaging protocol across all the major cloud IoT platforms as well as highly scalable applications, like Facebook Messenger.

Follow along with this series, starting with basic string publishing. Ever since ‘00, when the next year rolls around I think, “Welcome to the future!” Every year it feels much truer, and how could 2020 be any less? (UPDATE: 🤦) I’m excited about what we have planned for you this year. Among other things, we’re upping our commitment to MQTT in a big way. Stay tuned for announcements on that in the coming months. For the moment, though, I want to address the current feature set *groov* EPIC offers for MQTT, [the lightweight pub-sub communication protocol for IoT](https://blog.opto22.com/optoblog/request-response-vs-pub-sub-part-1). With so many ways to do it—via *groov* Manage, Node-RED, or Ignition Edge—you may be wondering which, if any, is right for your application. In this series, I’m going to look at different scenarios where you might want to use MQTT, then show you how to get started.
