New video shows how to access data no matter where your Node-RED server is running.

The Node-RED how-to video series continues with some tips on using certificates. Recent videos in the series covered why you should run Node-RED on groov devices, and how to install and configure Opto 22 Node-RED packages for PAC Control, groov I/O and groov View.

Now Terry Orchard is back at the demo desk to show you how to use both self-signed and Certificate Authority certificates to help move data between groov RIO and EPIC, no matter where your Node-RED server is running.

Using powerful built-in software, it’s easy to add more functionality to the multifunction, mixed signal I/O on groov RIO, including using RTD temperature probes with minimal code.

The groov RIO MM1, MM2, and even the groov EPIC GRV-MM1001-10 modules are extremely flexible, with an incredible number of software configurable options. Even with all that potential, you can do more when you combine this I/O with software tools like PAC Control, CODESYS, Node-RED, and custom Linux programs.

A great way to see this is with RTD sensors.

The Node-RED package video series wraps up with a closer look at groov View nodes.

If you've been following the OptoBlog, you've noticed we have a new series of Node-RED videos dedicated to explaining all the Opto 22 Node-RED packages available for your groov EPIC or RIO device. The last video in this 5-part series is now available.

Terry Orchard is back in the OptoStudio to explain groov View nodes. You'll learn about Read and Write, review how the nodes are configured, and see some examples of how they can be used.

The Opto 22 node packages for Node-RED video series continues with a focus on groov I/O nodes.

Get ready for another video that explains how and why to use the Node-RED programming tool on groov EPIC. In this new video, Terry Orchard explains the different types of groov I/O nodes, gives some examples of how to use them, and explains what makes them different from other nodes.

Before watching, you might want to review the Node-RED Package Intro and Configuration video. This  will provide some background on how the nodes were initially set up that are now being used in this latest I/O video.

Now, Terry has a flow ready to go with some examples that make it easy to follow along. Watch and learn.

Learn how to use Node-RED with the PAC Control node; watch the next video in our new series.

Have you been watching Terry Orchard's latest Node-RED video series that explains why you should run Node-RED on Opto 22 groov products? Last week's OptoBlog post shared how to get started with configuring the Node-RED packages so they're ready to use.

This week we move on to more details about the PAC Control node package. Watch as Terry explains in this latest video: Opto 22 Node-RED Packages: PAC Control.

Next video in our new Node-RED series: how to install and configure Opto 22 Node-RED packages.

Did you catch last week's video that made the case for why you should run Node-RED on groov EPIC and RIO? If you missed it, watch that first video to hear Opto 22's Terry Orchard explain why the groov platform is ideal for Node-RED and your IIoT and automation projects.

Next up in the series is Opto 22 Node-RED Packages: Introduction and Configuration. You'll learn how to install these packages and how to configure them so they're ready to use.

Hear from Opto 22's Terry Orchard as he makes the case for why groov EPIC and RIO are the ideal platforms for running Node-RED programming software.

Opto 22's groov EPIC and RIO products are designed to give you multiple options when it comes to developing applications for your control systems.

Node-RED is fast becoming one of the more popular options, and this new video explains why running Node-RED on groov EPIC or groov RIO is the best choice for your industrial automation projects.

Learn best practices for managing Node-RED projects on groov devices.

It’s important to be able to manage Node-RED projects for recovery, version control, copying flows to other devices, and sharing code. There are several ways to do this, but what should you be aware of and what are the best practices for doing this on a groov device? 

See what people were watching in 2022 on the OptoVideo YouTube channel.

The start of a new year is a good time for reflecting on what worked well the previous year. So we took a look at our OptoVideo channel on YouTube to see what videos received the most views and proved to be the most popular in 2022.

Review the new Top 10 Videos of 2022 playlist to see what you might have missed, or re-watch some valuable content. Topics range from programming with Node-RED, to unlocking the power of the edge with Ignition, to using the new OPC UA server on groov RIO.

New categories and reorganization of topics are just some of the reasons to visit the OptoForums.

Whether you're new to using Opto 22 products or a long-time user, you can benefit from checking out the OptoForums. It's where engineering minds meet to post questions, answer fellow forum user questions, recommend solutions or even provide code samples—all related to Opto 22 hardware and software.

Moderated by Opto 22's Ben Orchard and Terry Orchard, the Forums are another great resource to keep bookmarked for troubleshooting or application advice.

And the Forums recently went through some reorganization, with more topics and categories added to help you find your answers more quickly and efficiently. Take a look at what's new.
