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.
Opto 22 will be sponsoring and participating in three Ignition-related events in Orlando in February. If you plan on attending the annual ARC Industry Forum, you’ll want to extend your visit that week to include one or more of these Inductive Automation events.
Meet Blendtech, a division of PT Industrial Electric and supplier of Terminal Automation Systems (TAS). A TAS is commonly used to automate the processes at petroleum distribution terminals to keep them running efficiently and in compliance with government regulations.
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 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.
groov EPIC firmware version 1.5.0 is available now and has several great new features and a few bug fixes. While our groov EPIC Readme file has all the technical details, here’s a sweeping look at the new features I’m most excited about.

The end of 2019 is quickly approaching, and the Opto 22 team is once again preparing for the holidays.
As we look back on 2019, it was another EPIC year that included exciting new features and changes for the groov EPIC system. Here’s a recap of some of the highlights and our upcoming holiday schedule.
In our latest video, Applications Engineer Ben Orchard is back to give you step-by-step instructions for reading serial data via the EPIC’s USB port with a RS-232 to USB converter.
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:
