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.

You’ve heard the rumors. Now, as an OptoBlog subscriber, you can be first in line...

Coming next month: groov RIO®, a new family of intelligent, standalone, Ethernet-based, PoE-powered, remote I/O units for IIoT and automation applications.

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.

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.

Curious to get your hands on a groov EPIC learning center (LC)? So was I. Lucky me, this was dropped off at my cubicle recently. Let’s see what’s inside!

One of the new features in recent versions of the groov EPIC firmware (R1.4.0+) that hasn’t gotten much attention yet is the built-in virtual private network (VPN) client. I’m excited about it because it’s an incredibly rare feature in PLCs and PACs and makes it much easier to create a secure architecture for managing remote equipment.

Why? Because a VPN essentially creates a secure tunnel through the internet—using encryption and user authentication—that can connect remote EPICs to your PC or trusted company network. From a security and connectivity standpoint, it’s like the EPIC is on your desk or in your facility, protected in all the ways you protect your company network. Anything you can do with a locally networked device, you can do with a remote system using VPN.

How one integrator used the remote connectivity in groov EPIC and groov View to save his systems from Midwest storms.

Rainstorms have pounded Wisconsin this season, along with much of the Midwestern United States, producing strong winds, flood waters, and tornadoes. Opto 22 field sales rep Dave Engsberg calls this area home and shared a story last week about one groov EPIC system on a particularly rainy night.

His story is a great example of what secure remote connectivity can mean for your applications: the difference between continuing operations or being submerged under water.

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.

Step inside Opto 22 HQ again for day 2 of groov EPIC training.

The Outside-In series brings you an outsider’s perspective into the way Opto 22 operates behind the scenes. Today, we’re back in Temecula, CA (not Australia… I know! I was surprised too) for the next day of groov EPIC® system factory training. If you missed the first day, the class was introduced to groov Manage and PAC Control™. Plus, we got to see Terry Orchard demo Linux® secure shell access on the EPIC.

Day 2 wraps up PAC Control and covers PAC Display™, groov View™, Ignition Edge® and CODESYS®. If you’re interested in the hands-on training available for HMI/SCADA development or IEC 61131-3 languages on the EPIC platform, keep reading.

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.
