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.

groov EPIC Security Series, Part 4: User Accounts

Posted by Ben Orchard on May 10, 2019 3:12:44 PM

In this blog post, let’s take a closer look at user accounts on the groov EPIC system, and how you can improve your system security by giving users and services fine-grained access to applications running on EPIC. In other words, make sure each person or service has only the access they really need and nothing more.

But before we get deep into user accounts, let’s first discuss user account credentials. Take a moment and ask yourself the following questions:

Do you use the same password for multiple accounts?
Do you use a mix of punctuation and capital letters in your passwords?
Do you use long phrases as your passwords?

groov EPIC Security Series, Part 2: What's a Firewall?

Posted by Ben Orchard on Apr 17, 2019 2:41:07 PM

Ever notice how emergency exits in a building open outward? Then, to keep the building secure, they are usually locked from the outside. You can get out easily enough, but you can’t get in that way.

However, on a building’s main front entrance, the door often swings in so you can enter. Typically, there is a security guard or perhaps a receptionist there to check your ID and keep an eye on the comings and goings.

New webinar series: Why groov EPIC?

Posted by Janice Colmer on Nov 8, 2018 2:52:46 PM

Join Opto 22 engineers to learn why groov EPIC is right for your future applications.

The cutting edge technology that’s part of the groov EPIC (Edge Programmable Industrial Controller) system is crucial for IIoT and automation projects in today’s world. With the convergence of OT and IT in recent years, it’s important to understand how groov EPIC is bridging the gap between these operational and information technologies.

This webinar is the first in a multi-part series describing why groov EPIC was developed for the future of automation and IIoT.
