Take advantage of a new section of Opto 22's website devoted to groov RIO resources and tools.

As an OptoBlog subscriber, you've heard us talking about our latest edge I/O offering, groov RIO (GRV-R7-MM1001-10). It's I/O for the IIoT™. We've previously shared a press release, video, webinar, and a white paper resource for this exciting new product. And now there is one place to go for all your groov RIO questions...

Our MQTT series continues with a deep dive into groov EPIC’s (and now groov RIO’s) features for high-reliability MQTT networks.

Part 1 - MQTT: Basic publishing with groov EPIC
Part 2 - MQTT: Faster, better with Sparkplug B

Topics: Node-RED, MQTT, Ignition Edge, groov EPIC, groov Manage, Sparkplug, MQTT implementation, groov RIO

Follow along with Opto 22's Benson Hougland as he presents a live demonstration of the recently released groov RIO.

groov RIO (GRV-R7-MM1001-10) is available now with all of the features and capabilities you’ve heard about. But it’s one thing to read about it and another thing to see it for yourself.

With the latest firmware update, groov EPIC gets I/O for the IIoT and more

Out this week, groov EPIC firmware version 2.0 is a milestone for the platform, and there are more than a few reasons to consider updating. Here’s an overview of what’s included.

Topics: Updates, PAC Control, IIoT, Node-RED, MQTT, Codesys, groov EPIC, groov RIO

In part 2 of our series, we look at how to set up groov Manage and Ignition Edge for publishing with Sparkplug B payloads.

Part 1 - MQTT: Basic publishing with groov EPIC
Part 2 - MQTT: Faster, better with Sparkplug B
Part 3 - MQTT: Mission-critical fault tolerance

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.

The OpenJS Foundation and nodered.org have officially released Node-RED version 1.0!

Since the previous major Node-RED version v0.20, there have been big changes and improvements to both the visual editor on the surface and the runtime under the hood. These improvements are what truly make this a full version 1.0 update, and not just an iterative v0.21. This blog post will cover what has been updated or changed at a high level, and discuss the impact on users of Node-RED running on groov EPIC.

Part 2 - MQTT: Faster, better with Sparkplug B
Part 3 - MQTT: Mission-critical fault tolerance

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? 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. 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 and show you how to get started.

Watch these new groov EPIC videos for tips on using your Modbus TCP devices with groov View, PAC Control, Node-RED, and Inductive Automation's Ignition software.

Opto 22 engineer Ben Orchard is back in the Opto 22 studio with several new video lessons on communicating to Modbus TCP devices with a groov EPIC processor.

For each lesson, Ben is using a groov EPIC Learning Center (GRV-EPIC-LC) along with a Modbus SATEC P130 power meter, which is measuring the voltage and frequency of the mains power in our studio.

Opto 22 speaks up for open-source software.

For this month’s IoT feature in Design World magazine, Opto 22 had the chance to weigh in on the value that open-source software brings to industrial automation.

Some key points for the industry:

• Open source is everywhere in the enterprise and consumer sectors, powering innovation in products, services, and projects we all know.
• Open source changes the economic model for industry, freeing engineers and end users from the trap of vendor
  lock-in.
• Open source accelerates innovation and offers key technologies that empower IIoT growth.
