MQTT: Faster, better with Sparkplug B

Posted by Josh Eastburn on Feb 18, 2020 3:30:40 PM

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.

What's new in Node-RED v1.0

Posted by Terry Orchard on Jan 22, 2020 1:43:14 PM

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.

MQTT: Basic publishing with groov EPIC

Posted by Josh Eastburn on Jan 8, 2020 8:35:33 AM

Wondering how to implement MQTT with groov EPIC? 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? 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.

Video series gives you tips for using Modbus TCP devices with groov EPIC

Posted by Janice Colmer on Jan 7, 2020 9:09:43 AM

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.

Open source is the future of automation

Posted by Josh Eastburn on Dec 4, 2019 8:00:00 AM

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.

An EPIC case study in the oil and gas industry

Posted by Janice Colmer on Oct 2, 2019 7:48:56 AM

Learn how tech-based company netDNA automates water management for fracking and water transfer with the help of groov EPIC.

In the oil and gas industry, technological advances like hydraulic fracturing (fracking) and horizontal drilling have caused a boom in exploration and drilling. The initial “gold rush” approach to oil and gas development focused on people resources, with most work done manually.

But now companies are looking to add automation in the field, especially for water pumping and treatment, key ingredients in successful unconventional oil and natural gas production. In an industry with remote, widely separated, and changeable operations, automation and data communications aren't easy.

Outside-in Journal: Training Day Part 3

Posted by Josh Eastburn on Sep 23, 2019 3:54:52 PM

See what the final day of Opto 22's factory training looks like from the inside.

As the resident engineer-in-training, I’ve taken on the job of communicating to the outside world what it looks like inside of Opto 22. I’ve started off by giving you a look into the mindset and technologies at work here through the lens of our on-site training. Follow these links if you missed part 1 or part 2 of the series.

Last time I left you hanging right when we were about to get into CODESYS® near the end of Day 2. Today I make good on that teaser, as well as looking at Day 3 content (including Node-RED, MQTT, and the groov View™ graphics library) before Ben and Norma wrap up the class with a lesson on design fundamentals.

Outside-In Journal: Training Day Part 1

Posted by Josh Eastburn on Sep 4, 2019 10:18:01 AM

Documenting the journey from the outside world into the world of Opto: First in a series.

After more than a decade as an automation engineer, I recently joined Opto 22’s marketing group. A few weeks ago, my workday was focused on maintaining the cell culture process automation of a world-class pharmaceutical manufacturer. This system had dozens of distributed controllers and hundreds of devices that worked together to deliver thousands of kilograms of the finest monoclonal antibodies you’ve ever seen. It was big.

What I enjoyed most about my job, though, was helping other engineers succeed. In the early years, I learned pretty quickly that you could take a group of smart people, give them bad tools, callous management, and a ridiculous schedule, and they would fail every time. I did the best I could to fix the managerial and scheduling issues, but the tools were always a limitation.

Now it’s my job to help connect other engineers with the kinds of tools and technologies I wish I’d had. I’m kicking it off with a deep-dive into the first place I visited as a new Opto employee: the training room.

If you’re wondering whether it’s worth your time and money to get some Opto training yourself, I’ll be walking through everything you can expect to experience.
